Key tree species boost Amazon forest restoration, new study shows
- A study in Global Change Biology shows that just 15 to 25 tree species make up nearly half of the trees and carbon stocks in regrowing Amazon forests.
- While pioneer species grow quickly, experts warn that forests need a robust succession of stronger trees to avoid ecological decline over time.
- Understanding these forest dynamics may help Brazil meet its international pledge to restore 12 million hectares (30 million acres) of forest by 2030.

South Africa’s new gold rush: Big promises, closed books in new carbon frontier
- The drought-adapted succulent spekboom (Portulacaria afra) has long been trumpeted as the crown prince of South Africa’s nature-based carbon sink solutions.
- The World Bank ensured its coronation with a $120 million outcome-based bond, structured and named in its honor.
- According to Amazon, the tech giant’s commitment to buy carbon credits from the first developer to draw on the bond gave other financiers the confidence to back the industrial-scale project. Does this make the tech giant the power behind the throne of an emerging nature-based carbon credit sector?
- Mongabay’s investigation uncovers a sector dominated by international corporations whose investment promises are hard to scrutinize, in a cautionary tale of what happens when projects fail.

Logging operations uncovered at Cambodian senator’s dam in the Cardamoms
- Construction of the Stung Russei Chrum Kandal hydropower dam inside Phnom Kravanh National Park, one of Cambodia’s largest protected rainforests, began in 2023.
- Satellite imagery suggests forest clearance and large-scale logging are happening beyond the authorized construction sites.
- Experts say the images reflect a wider pattern in Cambodia of exploitation of licenses for dam development to further illegal logging operations.

Gulf of Mexico’s unique Orca Basin shouldn’t become a carbon dump (commentary)
- Deep in the Gulf of Mexico, an ecosystem exists in water so salty and lacking in oxygen that its marine life is unique and virtually unstudied.
- Called the Orca Basin, it’s now the focus of a corporate effort to profit from fighting climate change by dumping tons of organic waste into its depths, a deep-sea biologist explains in a new op-ed.
- “The Orca Basin is not a waste repository waiting for a use. It is a living system that has been developing for thousands of years, hosting organisms we have barely begun to characterize, preserving a chemical and biological record we have barely begun to read,” the author argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

For 50 years, Philip Fearnside has calculated the costs of losing the Amazon
- Philip Fearnside has spent 50 years studying the practical limits of Amazon development, beginning with the agricultural settlements built along Brazil’s Trans-Amazonian Highway. His work repeatedly asked who benefits from projects and who bears their longer-term costs.
- He produced influential research on deforestation, forest carbon, tropical dams, and the wider effects of roads, often challenging official assumptions about emissions and economic viability. He later contributed to the IPCC’s work on climate change.
- Fearnside has paired research with public engagement, publishing in Portuguese, writing for Amazônia Real and Mongabay, speaking to journalists, and testifying on projects including the BR-319 highway. That role has also made him a target of hostility, including at a 2021 public hearing where his microphone was cut.
- Former students and colleagues credit him with generous, exacting mentorship and an unusual command of the scientific literature. At a recent tribute at Brazil’s National Institute for Amazonian Research, he rejected any suggestion of a farewell: he intends to keep working.

Global sea surface temperatures reach a record high, again
Global sea surface temperatures have reached a record high, raising serious concerns for global Earth systems, according to new data released by the European Union’s Copernicus Climate Change Service (C3S). On Aug. 22, the daily global average sea surface temperature, outside polar regions, reached 21.1° Celsius (69.98° Fahrenheit), exceeding the previous record set in March […]
Can REDD+ deliver for Philippines’ Iraya Mangyan?
- The Mindoro Forest and Biodiversity Conservation Programme combines Indigenous forest patrols, ancestral-domain support, carbon monitoring and livelihood projects to protect more than 40,000 hectares (nearly 99,000 acres) of Iraya Mangyan forest.
- Indigenous patrollers and local officials say the program has already strengthened monitoring and helped reduce timber poaching and small-scale mining, while surveys have documented hundreds of plant and animal species across the project area.
- Community nurseries and paid conservation roles are creating early livelihood opportunities, but many benefits remain limited and uneven while the project awaits verification, a finalized benefit-sharing agreement and carbon revenue expected no earlier than around 2029.
- Whether the program can deliver lasting benefits will depend on finalizing a transparent revenue-sharing agreement, sustaining patrols and livelihoods during the long wait for carbon income, and ensuring the Iraya retain a meaningful role in decisions over their forests.

US proposes rescinding Roadless Rule protections for national forests
Aug. 25 is a National Day of Action to support U.S. national parks and public lands. One focus of the event is the U.S. government’s intention to rescind a rule that bans road construction and industrial logging across more than 23 million hectares (57 million acres) of national forest land. The 2001 Roadless Rule, has […]
Why carbon markets alone won’t save Southeast Asia’s concessions forests
New research suggests a “massive and untapped” opportunity for conservation within commercial concessions in Southeast Asia, reports Mongabay’s Carolyn Cowan. Using satellite data, researchers identified roughly 42 million hectares (104 million acres) of intact forest still standing inside logging, timber, rubber and oil palm concessions across Cambodia, Indonesia, Malaysia and Myanmar. The study suggests that […]
Mariano Cenamo, advocate for a sustainable Amazon bioeconomy, has died, aged 46
- Mariano Cenamo spent more than two decades trying to make standing forests economically competitive with cattle ranching and other activities driving Amazon deforestation, helping establish Idesam and later backing a new generation of sustainable businesses.
- His work evolved from early efforts on forest carbon and REDD+ to agroforestry, bioeconomy ventures, investment, and entrepreneurship, always centered on creating practical sources of income for people living in the Amazon.
- Drawing on Cenamo’s own writings and interviews, as well as Vanessa Adachi’s posthumous portrait in Reset, this obituary explores the ideas, motivations, and personal style behind one of the Amazon’s most influential environmental entrepreneurs.
- Cenamo died on July 10 after several years with cancer. He was 46.

Suriname moves to evict Mennonites and illegal Amazon settlers
- The government in Suriname has created a task force to crack down on land developers who illegally clear the Amazon Rainforest for agriculture and cattle ranching.
- Many areas under development are connected to Mennonites who migrated to the country from other parts of the region to help meet a domestic demand for food production.
- Conservationists warn that the group’s history of industrial-scale clearing and unauthorized ranching in other nations puts the rainforest at risk.
- Some Mennonites have received a deurwaardersexploot, a written notice delivered by a bailiff to appear in court, according to Suriname President Jennifer Geerlings-Simons.

Carbon markets alone won’t keep Southeast Asia’s forests standing, study says
- A new study has identified “massive and untapped” conservation potential within forestry and plantation concessions in Southeast Asia.
- Roughly 42 million hectares of forests remain standing inside logging, oil palm, timber and rubber plantation concessions across the region, the study says.
- The researchers examined what it would take to financially incentivize forest conservation inside these concessions, finding that using carbon markets alone would require carbon prices many times higher than current values.
- They point to the need for diversified sources of conservation funding to complement carbon markets, such as blended finance, green bonds and payment for ecosystems services, as well as more supportive governance frameworks that elevate the viability of conservation over development.

How carbon markets can succeed & also serve Global South communities (commentary)
- The world’s forests provide essential ecosystem services, capture and store huge amounts of carbon dioxide, face enormous pressure, and need sustained economic incentives if they are to survive.
- So why has the voluntary carbon market consistently fallen short of its promise to support forest conservation and communities, a new op-ed asks.
- “The ecosystem services forests provide are worth something, and the people who live in and protect those forests must be the primary beneficiaries of that value. Anything short of that is not conservation but a new form of exploitation,” the author argues.
- This article is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

The unsung biodiversity of the Mediterranean Sea needs urgent protection
The Mediterranean Sea accounts for less than 1% of the world’s ocean surface water, but it contains roughly 18% of global marine biodiversity. It is home to 150 million people along its coastline (roughly equivalent to Russia’s population). And it sequesters 17.2 million metric tons of CO2 each year. Joining the Newscast this week to […]
Scientists use AI to produce first high-resolution map of global seagrass extent
- Scientists have produced the first high-resolution map of seagrass ecosystems around the world.
- Data from the map reveal that 70% of global seagrass cover is concentrated off the coasts of just five countries.
- The map also found that nearly 80% of seagrass loss happened outside marine protected areas, emphasizing the importance of targeted conservation action.
- Seagrass ecosystems play an important role in protecting coastlines and carbon sequestration; however, they face threats from hurricanes, coastal development, and marine heat waves.

Can selective logging help the Congo Basin store more carbon?
- A recent study created a machine-learning program that estimated the amount of carbon dioxide already stored, and sequestered annually, by rainforests in Central Africa’s Congo Basin, the planet’s largest forested carbon sink.
- They found that managed logging concessions, which remove a small number of large trees annually and strictly control other human activities, made up more than half of the net carbon removed by Congo Basin rainforests.
- The authors say these results suggest that expanding logging concessions could help the Congo Basin sequester more carbon while also providing locals with a source of income.
- Other experts, however, argue that addressing local conflicts that lead to illegal forest clearing would be a better way to benefit these forests.

Laser scanning forests may boost carbon estimates, but credibility questions linger
- Ground-based laser scanning, called LiDAR, can be used to make detailed maps of forest structure.
- Such detail can allow for more accurate estimates of the amount of carbon stored in aboveground vegetation, which is helpful for assessing the outcomes of reforestation projects and assigning an accurate number of carbon credits.
- Carbon credits, bought and sold on the carbon market, are used by companies and other entities to offset their own greenhouse gas emissions.
- But experts caution that transparency, not estimation accuracy, remains the carbon market’s biggest challenge.

‘Rare animals, photography and Instagram’ could help an Ivorian rainforest
- In late May, Mongabay accompanied a group of conservationists and scientists to Taï National Park — a large rainforest in Côte d’Ivoire famous for its habituated western chimpanzees.
- Despite the presence of these charismatic apes, the park gets relatively few visitors, whose presence could help to support conservation efforts and deter poachers.
- Conservationists are now planning to promote niche tourism in the park and support work by the Ivorian Office of Parks and Reserves (OIPR) to protect Taï’s stunning biodiversity.
- Chimpanzee sightings are a major attraction for any visitor to the park, but other animals, including one of the world’s largest scorpions and Africa’s largest and rarest owl, could also prove to be a draw for those looking for an adventure-filled experience.

World Peatland Day honors a crucial ecosystem in the fight against climate change
Peatlands are boggy wet ecosystems found from boreal forests in the Russian Arctic to the tropics of central Africa. Typically, when vegetation decomposes it releases carbon dioxide into the atmosphere. However, when that same organic matter falls in a bog and is covered with water, carbon gets trapped and becomes sequestered there, sometimes for millennia. […]
A ‘symphony’ of wildlife suggests carbon financing is working in Sierra Leone
- A study conducted in Sierra Leone’s Gola Rainforest National Park found that the United Nations Reducing Emissions from Deforestation and forest Degradation (REDD+) financing program, set up to ensure that forests sequester carbon, also confers some benefits to the park’s animal biodiversity.
- Compared to a neighboring protected area without REDD+ funding and a bordering community-owned agroforestry area, the national park had higher soundscape saturation, a proxy for biodiversity. However, the authors also found that the agroforestry area had a higher diversity of insects than the two other study areas.
- The study emphasizes that carbon financing programs can provide benefits outside of storing carbon, but experts also highlight that it shows that on-the-ground monitoring can be cheaply, effectively added to programs like REDD+ to help better conserve forests as whole ecosystems.

The most underfunded climate opportunities may be at sea
- At the Philanthropy Asia Summit’s “Sea Change” panel on ocean-climate solutions in Asia, speakers highlighted a mismatch between the ocean’s importance to the climate transition and the tiny share of philanthropic funding directed to ocean-climate work.
- Ocean philanthropy has long focused on conservation, fisheries, and coastal livelihoods, but climate change is now threatening many of those gains while also making the ocean central to mitigation through offshore wind, cleaner shipping, blue carbon, and coastal resilience.
- Philanthropy cannot finance offshore wind farms or the decarbonization of global shipping, but it can play a catalytic role by funding policy design, marine spatial planning, community engagement, technical research, coordination, and local capacity.
- Some of the strongest opportunities for funders lie in Asia, where offshore wind, ports, shipbuilding, shipping routes, and coastal communities converge, and where early philanthropic support can help make large-scale transitions faster, more inclusive, and more credible.

Mangroves are ‘powerful and undervalued’ for curbing nitrogen pollution, study finds
Mangrove forests could help sequester more than five million metric tons of nitrogen pollution from coastal ecosystems across the Earth if they are restored and protected, a recent study found. Nitrogen pollution typically comes from synthetic fertilizers largely used in agriculture or from human waste seeping into water sources. Nitrogen is an essential nutrient for […]
Agriculture drives most tropical peatland loss in Indonesia, Peru and DRC: Study
Agriculture is the biggest driver of peatland loss in Indonesia, Peru and the Democratic Republic of Congo, home to the largest expanses of tropical peatlands in the world, a recent study has found. Peatlands are crucial in the fight against climate change: They cover less than 3% of the world’s landmass, but sequester more carbon […]
Cerrado’s hidden carbon highlights gaps in Brazil’s conservation policy
- Hectare for hectare, wetlands in the Brazilian Cerrado holds six times more carbon than the lowland Amazon, according to the first study to estimate carbon stocks in the biome.
- Researchers also found that these wetlands are less stable than other tropical peatlands, and thus potentially more vulnerable to changes in rainfall and groundwater levels.
- Satellite mapping suggests these wetlands may also cover as much as 16.7 million hectares (41 million acres), or 2% of Brazil’s total landmass, a far greater area than previously thought.
- Researchers say they hope that more accurate estimates of the Cerrado’s carbon storage may help change perceptions of it as an environmentally insignificant “sacrifice biome” suited for industrial agriculture.

10 forces that could reshape the future of the world’s forests
- A new horizon scan identifies ten emerging forces—spanning politics, finance and technology—that are likely to shape forests over the next decade, increasing uncertainty for ecosystems and the people who depend on them.
- Traditional funding for conservation is weakening as public aid declines, while new mechanisms—from carbon markets to direct financing for Indigenous and local communities—are expanding unevenly.
- Advances in remote sensing, AI and connectivity are improving monitoring and accountability, but are also enabling illegal activities and accelerating pressures in some regions.
- Growing demand for critical minerals, shifting trade rules and tighter political control over civil society are reshaping forest governance, fragmenting authority and redistributing risks and benefits.

Chile’s ancient conifers host underground web of life that sustains forests: Study
- Estimated to be more than 2,400 years old, one alerce tree in Chile’s Alerce Costero National Park hosts about twice as much fungal diversity underground as younger alerce trees, a team of researchers found.
- The scientists found 361 fungal DNA sequences unique to this tree, indicating that older trees harbor a vaster fungal network that benefits other plants on the forest floor.
- Real estate expansion, climate change and infrastructure projects continue to threaten the alerce, which is listed as endangered. Although Chile protects the species, experts say older trees that support complex ecosystems should enjoy higher levels of protection and limited interaction from humans.

The underwater meadows that help keep beaches from disappearing
Seagrass meadows, which rarely draw the attention given to coral reefs or mangrove forests, perform a steady but important task: they help hold coasts in place. The plants anchor themselves in sediment through dense root systems that bind the seabed, similar to how forests stabilize soil on land. Oscar Serrano Gras, a researcher affiliated with […]
‘Ancient’ carbon venting from lakes in the Congo Basin peatlands: Study
- A new study finds that lakes are likely releasing carbon that’s been held in the peatlands of the Congo Basin for thousands of years.
- Scientists know these lakes release carbon dioxide, which until now was thought to result from recently decayed plant matter.
- A team of researchers radiocarbon-dated carbon from water samples to show that some of the CO₂ probably has much older origins, reporting their findings in a new study.
- The authors says more work is needed to understand the implications of this ancient carbon release for carbon dynamics and climate change.

Grasslands and wetlands are being lost to agriculture four times faster than forests
Wild ecosystems such as grassland savannas, bush and open wetlands are losing ground worldwide to make way for large pastures and grain fields. A new study found these ecosystems are being converted at a rate four times higher than for forests. Over a 15-year period, from 2005-2020, researchers found that 190 million hectares (470 […]
A South African reserve shows how carbon can catalyze rewilding conservation
- Managers have spent decades expanding Tswalu Kalahari Reserve in South Africa to its present 118,000-hectare (292,000-acre) size and bringing native species to the former livestock rangelands that have been incorporated into the reserve.
- In addition to providing a home for wildlife species at the high-end safari reserve, Tswalu is also measuring the impact on soil carbon stores in the dry savanna ecosystem.
- Research has shown that careful application of rewilding can potentially bring carbon benefits, effectively addressing biodiversity loss and climate change together, though the results depend on contexts and the complex dynamics of soil ecosystems.
- Tswalu has begun selling carbon credits, which it says will help fund continued conservation on the reserve.

Forest advocates accuse EU energy firm of Dutch biomass certification fraud
- The sustainability certification of forest biomass produced to generate industrial-scale energy has long been controversial and called into question.
- Wood pellet companies argue their product is sustainable and doesn’t cause deforestation, while governments claim biomass burning results in climate-neutral emissions, which is why they offer subsides to energy companies burning sustainability certified forest biomass.
- However, forest advocates and scientists have provided significant evidence that forest biomass production contributes to deforestation, is not sustainable and that burning wood generates more carbon emissions per unit of energy than coal.
- In an unprecedented move, Dutch law enforcement is considering a criminal investigation into RWE, one of the Netherlands’ largest energy providers, after a Dutch forest advocate alleged that the firm dodges biomass certification rules, using wood pellets imported from Malaysia sourced not from sawmill waste, but allegedly from whole trees.

Climate or biodiversity? Global study maps out forestation’s dilemma
- A new study maps areas designated for potential carbon dioxide removal projects, such as planting forests or bioenergy crops, that might conflict with biodiversity hotspots.
- Such climate strategies could harm species if they change existing ecosystems or use too much land.
- The study points to the importance of more careful site selection for these projects.
- The authors of the study also note the importance of reducing humanity’s CO2 emissions, rather than relying solely on removing CO2 from the atmosphere later on.

Nepal signs major carbon deal but community access remains challenging
- Nepal is the first country in Asia to sign an agreement potentially worth $55 million with the LEAF Coalition to reduce emissions from deforestation across three provinces.
- Experts and community representatives emphasize the deal’s success hinges on local people’s access, transparent funding, strong safeguards and inclusive benefit sharing.
- While communities push for 80% of the funds to go directly to forest communities, bureaucratic processes, administrative fees and gaps in coordination and capacity could limit direct access, echoing lessons from Nepal’s previous REDD+ programs.

The cost of compliance with the EUDR will limit its impact on reducing deforestation (commentary)
- Many links in agri-commodity supply chains have very narrow profit margins, making them particularly sensitive to additional costs.
- The costs of implementing “zero deforestation” agri-commodity supply chain commitments requiring physical segregation are likely to cause positively engaged companies to avoid commodities grown in regions with active deforestation, leaving companies with no deforestation commitments in their place.
- Contrary to dominant beliefs in adding controls and costs, systemically linking markets and public policy in producer regions enables cheaper, more price-competitive and thus more effective forest-climate strategies; jurisdictional REDD+ is poised to provide such a bridge, argue Bjørn Rask Thomsen, Europe Director at Earth Innovation Institute and former food industry CEO and Daniel Nepstad, Executive Director and President at Earth Innovation Institute in this op-ed.

New study assesses geoengineering marine ecosystem risks, knowledge gaps
- A new review study examines the current research regarding the risks that various geoengineering approaches pose to marine ecosystems.
- The study looked particularly at a range of marine carbon dioxide removal (mCDR) methods, along with solar radiation modification (SRM) technologies, and found that some approaches carry fewer risks than others.
- Electrochemical ocean alkalinity enhancement and anoxic storage of terrestrial biomass in the deep ocean (utilizing crop waste, for example) carry fewer risks to marine ecosystems than some carbon dioxide removal methods, such as those that would add nutrients to seawater to promote major plankton growth.
- However, better models, increased field testing, and better geoengineering regulatory oversight are needed to fully assess potential geoengineering marine ecosystem impacts, especially if commercialization proceeds. Public fears over field testing also need to be allayed.

Mapping underground fungal networks: Interview with SPUN’s Toby Kiers
- Mycorrhizal fungi are found in every soil system on Earth, and have symbiotic relationships with the plants whose roots they live on.
- They receive carbon dioxide from plants in exchange for nutrients, making them major carbon repositories and an important tool for carbon sequestration.
- The Society for the Protection of Underground Networks (SPUN) is deploying a wide range of technologies, from remote sensing to imaging robots, to map these crucial underground networks.
- “We think of these networks as one of Earth’s circulatory systems, but people are not paying attention,” SPUN co-founder Toby Kiers tells Mongabay in an interview.

Cambodia’s canal mega-project threatens coastal communities and marine life
- The Cambodian government is set to begin construction of the Funan Techo Canal, a nearly $1.2 billion, 180-kilometer (112-mile) waterway navigation project that will cut across four provinces to connect the Mekong River to the sea.
- The primary rationale for building the canal is to reduce Cambodia’s shipping costs as well as to generate jobs and economic development.
- Mongabay has followed this mega-project’s development for more than a year, speaking with more than 50 people living along the canal’s proposed route. Virtually everyone we spoke with noted that the government has provided very little information about the project, and amid the uncertainty, fear has taken root.
- In coastal communities in Kep province, where the canal will meet the sea and a new port and deepwater shipping lanes will be built, fishers we spoke with said they worried they’d lose their homes and that construction would render their already meager fishing grounds barren and inaccessible.

‘Blew us away’: Researchers find nitrogen boost spurs faster tropical forest growth
- A new study in Panama finds that nitrogen availability limits forest growth in the early stages of regeneration.
- Nitrogen addition to newly cleared land and 10-year-old forests substantially boosted regeneration, though adding nutrients to older forests did not have the same effect
- The study also found that phosphorus availability did not limit forest growth at any stage of forest maturity.
- The researchers recommend ensuring nitrogen-fixing species are included during reforestation.

In Brazil, planting forests for carbon credits could help ecosystem restoration
- The sale of carbon credits from forest restoration is taking off in Brazil, but the sector still needs to tackle mistrust, the complexity of ecosystem restoration and the long-term nature of the projects.
- Founded in 2021, Brazilian firm re.green commercially restores forests by selling carbon credits and has projects spanning 34,000 hectares (84,000 acres) in the Amazon and Atlantic Forest.
- The company aims to restore 1 million hectares (2.5 million acres) of tropical forests across Brazil. Its work so far has been recognized through an EarthShot Prize in 2025.
- As well as restoring ecosystems to sell high-integrity carbon credits, the company also works with the community and produces data and knowledge on forest restoration.

Earth Rover Program seeks to track the world’s soil health
- Leveraging tools from seismology — the study of earthquakes and the inside of our planet — the Earth Rover Program aims to provide critical data on the health of soil.
- Humans, and terrestrial life in general, depend on the soil for nourishment.
- Yet, in many parts of the world, soils are degraded, worn out and eroding away.
- The recently founded program involves the development of inexpensive technology that farmers and scientists alike can use to better understand soil health and what can be done to improve it.

Hidden heroes: Australian tree bark microbes consume greenhouse & toxic gases
- A new study carried out in Australia finds that the bark of common tree species holds diverse microbial communities, with trillions of microbes living on every tree.
- The research determined that many of these microbial species specialize in metabolizing methane, hydrogen, carbon monoxide and volatile organic compounds (VOCs).
- Methane is a powerful greenhouse gas, while hydrogen and carbon monoxide are considered indirect greenhouse gases. Carbon monoxide and VOCs are also both hazardous to human health.
- The study found that tree bark microbes play a significant, previously unknown role in atmospheric gas cycling, potentially boosting estimations of the climate benefits offered by global forests. Learning which tree species boast the best microbes for curbing climate change and pollution could better inform reforestation strategies.

Measuring biodiversity in a world of tree-planting pledges
- The Global Biodiversity Standard (TGBS) is a certification scheme for forest restoration projects that show positive outcomes for biodiversity.
- Each assessment includes a field visit by experts from regional hubs, who have been trained in TGBS methodology.
- The regional hubs also offer ongoing mentoring to projects, to promote internationally recognized best practices in restoration.
- One year on, TGBS has certified six sites, and 15 regional hubs offer mentoring.

Huge ‘blue carbon’ offsetting project takes root in the mangroves of Sierra Leone
- In October, a wholly owned subsidiary of West Africa Blue, a Mauritius-based company, signed a “blue carbon” offsetting deal with the 124 communities on the island of Sherbro in Sierre Leone.
- The agreement will reward the communities financially for conserving and restoring their mangroves, which act as a carbon sink.
- The funds will be generated by selling offsets on the voluntary carbon credit market, with revenues shared between West Africa Blue, the communities and the government of Sierra Leone.
- Though carbon offsetting projects have been subject to criticism in the past, community members on Sherbro say they’re optimistic about the improvements to their livelihoods that the project could bring.

The rise of CC35 and the business behind its climate deals
- The executive secretary of CC35, a climate network of capital cities in the Americas, used annual climate summits and other events to advance private interests in carbon credit businesses, a Mongabay investigation has found.
- His plan included persuading a provincial government in Argentina to sign a multimillion-dollar carbon contract with an associate facing fraud allegations in a parallel carbon business. According to a recent Mongabay investigation, the associate had pressured Indigenous communities in Brazil and Bolivia to sign abusive carbon deals, conceding rights for an area larger than Ireland.
- The head of CC35, Argentinian Sebastián Navarro, also failed to fulfill CC35’s commitment to cover all costs associated with Ecuador’s pavilion at COP28, after making false claims to the government and creating debts for the country.

Top-down projects, exotic trees, weak tenure: Congo Basin restoration misses the mark
- Despite a panoply of projects — from tree-planting drives to agroforestry schemes — a new study finds that much of what’s happening in the name of “forest restoration” in the Congo Basin may not be restoring forests at all, but largely focused on growing nonnative, commodity species.
- The research found nearly two-thirds of projects favored planting exotic species over native ones, primarily because they grow more quickly, require less care, and their seeds are easier to source.
- It also noted a lack of ecological monitoring, with few initiatives tracking tree survival rates, soil recovery or carbon storage, and most lasting less than five years — far too short to measure real ecological impact.
- Beyond agroforestry and fuelwood plantations, the study calls for approaches that promote natural regeneration, restore native biodiversity and reconnect fragmented habitats.

Scientists push for greater climate role for Latin America’s overlooked ecosystems
- Tropical forests are rightly regarded as important carbon sinks and crucial in the fight against climate change, but other tropical ecosystems have largely gone overlooked despite their carbon -sequestration potential.
- Peatlands, mangroves, coastal freshwater wetlands and seagrass meadows are just some of the ecosystems that have a potentially huge capacity to capture and store carbon, but don’t feature prominently enough — or at all — in the national climate plans of Latin American countries.
- Peatland soils can store between three and five times more carbon dioxide than other tropical ecosystems, with similar figures for mangroves and coastal freshwater wetlands.
- Seagrass meadows cover just 0.1% of the ocean floor, but can store up to 18% of global oceanic carbon.

SE Asia forest carbon projects sidelining social, biodiversity benefits, study finds
- Across Southeast Asia, forest carbon projects intended to offset greenhouse gas emissions are falling short on social justice safeguards, according to recent research.
- The study identifies weak governance, land tenure conflicts, corruption and fragmented policies as contributing to the shortcomings.
- Well-managed forest carbon initiatives have an important role to play in global efforts to reduce emissions, the researchers say, but they must center the rights of traditional custodians of forests.
- Against the backdrop of global democratic backsliding, experts urge greater scrutiny of project accountability to uphold social and environmental standards within the carbon sector.

How community custody empowered Ecuador’s crab catchers and revived its mangroves
- Under agreements for sustainable use and protection, Ecuador’s environment ministry has granted concessions for 98,000 hectares (about 242,000 acres) of mangrove forests to artisanal fishers in the Gulf of Guayaquil.
- The fishers can catch crabs to sell, but are committed to the protection of this valuable ecosystem, imposing closed seasons twice a year and refraining from catching female and juvenile crabs.
- The concessions represent 62% of the total area of mangrove forests in Ecuador, of which 80% are located in the Gulf of Guayaquil.
- This system has allowed for the conservation of mangroves for 26 years and has been shown to be effective in protecting this type of forest, which is capable of retaining up to five times more carbon than other tropical forests.

Saving forests won’t be enough if fossil fuels beneath them are still extracted, experts warn
- A new analysis finds that tropical forests in 68 countries sit atop fossil fuel deposits that, if extracted, would emit 317 billion metric tons of greenhouse gases — more than the remaining 1.5°C (2.7°F) carbon budget — revealing a major blind spot in global climate policy.
- Because Brazil’s proposed Tropical Forest Forever Facility (TFFF) focuses only on stopping deforestation, researchers warn it risks missing far larger emissions from potential oil, gas and coal extraction under protected forests.
- India, China and Indonesia hold the largest fossil reserves beneath forests, with Indonesia facing acute trade-offs as most of its coal lies under forest areas where mining threatens biodiversity and Indigenous communities, including rhino habitats in Borneo.
- Experts say that compensating countries for leaving fossil fuels unextracted — through mechanisms like debt swaps or climate finance — could unlock massive climate benefits, but fossil fuel phaseout remains excluded from TFFF negotiations despite growing calls to include it.

Indonesia labeled ‘Fossil of the Day’ for echoing industry talking points at COP30
- Indonesia has been publicly rebuked at COP30 with a “Fossil of the Day” award after civil society groups accused its delegation of echoing fossil fuel and carbon industry lobbyists during negotiations on Article 6.4, the U.N.’s new carbon market mechanism.
- Observers say Indonesia’s position closely mirrors the talking points in an industry-backed letter calling for weaker safeguards under Article 6.4 — a move critics warn could undermine the integrity of global carbon markets and benefit groups with financial stakes in nature-based carbon projects.
- Indonesia denies being influenced by lobbyists, even though at least 46 representatives from fossil fuel and heavy-industry companies are accredited under its delegation — raising broader concerns about corporate access to negotiations amid a COP already flooded with a record proportion of fossil fuel lobbyists.
- Experts warn Indonesia’s push to loosen Article 6.4 rules risks weakening international oversight, aligning the mechanism with the far less transparent Article 6.2, and potentially undermining both Indonesia’s climate credibility and the robustness of the Paris Agreement’s carbon market safeguards.

As Indonesia turns COP30 into carbon market showcase, critics warn of ‘hot air’
- Indonesia is using the COP30 climate summit to aggressively market its carbon credits, launching daily “Sellers Meet Buyers” sessions and seeking international commitments 6 despite unresolved integrity issues in its carbon market.
- Experts warn Indonesia’s credits risk being “hot air,” since its climate targets are rated “critically insufficient,” meaning many claimed reductions may not be real, additional or permanent — especially in forest-based projects.
- Forest and land-use credits, Indonesia’s biggest selling point, are among the riskiest, with high risks of overcrediting, leakage and nonpermanence; ongoing fires and deforestation further undermine credibility.
- Environmental groups say the carbon push distracts Indonesia from securing real climate finance, enabling wealthy nations to offset rather than cut emissions, while leaving Indonesia vulnerable to climate impacts and dependent on a fragile market.

How a ‘green gold rush’ in the Amazon led to dubious carbon deals on Indigenous lands
- A Mongabay investigation has found that companies without the financial or technical expertise signed deals with Indigenous communities in Brazil and Bolivia, covering millions of hectares of forest, for carbon and biodiversity credits.
- Many of the communities involved say they were rushed into signing, never had the chance to give consent, and didn’t understand what they were signing up to or even who with.
- Brazil’s Indigenous affairs agency has warned of legal insecurity and lack of standards in carbon credit initiatives, and an inquiry is underway — even as the businessmen involved target more than 1.7 million hectares in the tri-border area between Brazil, Bolivia and Peru.
- Two and a half years since the deals were made, Brazil’s Public Ministry has called for them to be annulled, following Mongabay’s repeated requests to the ministry for updates.

Three tracks to rescue 1.5°C: fossil exit, forest protection, and nature’s carbon (commentary)
- Ilona Szabó de Carvalho, co-founder and president of the Igarapé Institute and of the Green Bridge Facility, argues that keeping global warming below 1.5 °C requires action on three simultaneous fronts: phasing out fossil fuels, ending deforestation, and scaling up natural carbon capture in forests and oceans.
- She contends that energy decarbonization alone is insufficient; protecting and restoring ecosystems such as forests, wetlands, and mangroves is essential for both emissions reduction and resilience, and must be backed by transparent finance and accountability.
- With COP30 approaching in Belém, her piece calls for an integrated, finance-backed plan that ties together clean-energy expansion, a time-bound zero-deforestation roadmap, and rigorous safeguards for community-led nature-based solutions.

Why Sweden’s forest policy matters to the world (commentary)
- Sweden is one of the world’s largest exporters of forest-based products: paper, timber, cardboard and biofuels travel across the globe, ending up in your packaging, your books, in your home.
- A recent government proposal encourages fertilization with nitrogen to speed up tree growth, which may work in the short term but eventually fails and is leached into waterways, altering ecosystems and being released back into the atmosphere as greenhouse gases.
- “If a country with some of the world’s largest intact boreal forests chooses to double down on short-term extraction, it will not only undermine the EU’s climate goals — it will send a dangerous signal to other forest nations, from Canada to Brazil, that soil and biodiversity can be sacrificed in the name of so-called green growth,” a new op-ed argues.

Report identifies 10 emerging tech solutions to enhance planetary health
- A recent report underlines 10 emerging technologies offering potential to accelerate climate action, restore ecosystems, and drive sustainable innovation within safe planetary boundaries. These technologies include AI-supported Earth observation, automated food waste upcycling, green concrete and more.
- Innovative AI improvements in Earth observations (EO) can better identify and track human-caused environmental impacts and offer improved early warning alerts for planetary boundary overshoot. Such systems use AI-powered analytics to synthesize satellite, drone and ground-based data for near-real-time results.
- Artificial intelligence and automation can also work in tandem to manage citywide food waste programs, ensuring that food scraps are diverted from landfills or incineration, decreasing carbon emissions and reducing waste.
- Another tech solution is green concrete which could not only reduce emissions from traditional cement production, but when incorporated into infrastructure construction, can offer a permanent storage place for captured CO2.

Suriname’s plan to capitalize on carbon: Q&A with President Jennifer Geerlings-Simons
- Suriname’s first female president, Jennifer Geerlings-Simons, sat down with Mongabay to discuss her goals for the U.N. Climate Change Conference taking place next week in neighboring Brazil.
- She’s been a vocal proponent of climate financing for countries meeting their emission targets and conserving the rainforest.
- At the same time, Geerlings-Simons is grappling with Suriname’s deep-seated mining industry, which often skirts regulations and destroys natural ecosystems with mercury and cyanide.
- Geerlings-Simons said she recognizes the importance of extractive industries for funding the country’s infrastructure, law enforcement and the agencies that provide environmental oversight.

Beyond deforestation: redesigning how we protect and value tropical forests (analysis)
- Following his earlier essay tracing possible futures for the world’s forests, Mongabay founder and CEO Rhett Ayers Butler turns from diagnosis to design—asking what concrete interventions could still avert collapse. This piece explores how governance, finance, and stewardship might evolve in a second act for tropical forests.
- The essay argues that lasting protection depends structural reform: securing Indigenous land rights, treating governance as infrastructure, and creating steady finance that outlasts election cycles and aid projects.
- Butler also examines overlooked levers—from restoring degraded lands and valuing forests’ local cooling effects to rethinking “bioeconomies” and building regional cooperation across borders. Each points toward a shift from reactive conservation to deliberate, sustained design.

Australia to create a national park for 12,000 koalas
- The New South Wales government has unveiled plans for the Great Koala National Park, a 475,000-hectare reserve that combines existing protected areas with 176,000 hectares of state forest to safeguard an estimated 12,000 koalas and dozens of other threatened species.
- The move comes with a moratorium on native forest logging, $140 million in funding, and promises of new tourism infrastructure, though legislation to finalize the park is not expected until 2026 and is contingent on approval of a carbon credit scheme.
- Supporters hail the plan as a landmark conservation step that could boost biodiversity, generate carbon revenue, and create more sustainable jobs through ecotourism, while critics argue it sacrifices timber workers and delays certainty for communities.
- The decision reflects broader shifts in Australian forest policy, as states retreat from native forest logging, balancing ecological imperatives with political pressures from unions, industry, and rural constituencies.

There’s far less land available for reforestation than we think, study finds
- In recent years, policymakers have made pledges for huge tree-planting projects a cornerstone for meeting national carbon reduction goals, while doing little to seriously cut fossil fuel emissions. But a new study shows the carbon sequestration estimates made for those forestation projects may be wildly optimistic.
- The new research determined that land found suitable for forestation in past studies — an area about the size of India — shrank by as much as two-thirds when adverse impacts on biodiversity, food security and water resources were taken into account.
- When the new study figured in environmental and social constraints, the potential for existing tree-planting pledges to store a promised 40 gigatons of carbon by 2050, was reduced to just 12.5 gigatons — a significant sum, but far from what’s needed to offset continued fossil fuel use.
- The new study urges policymakers to be more pragmatic in their planting strategies, and prioritize lands best slated for permanent reforestation. Other researchers urge decision-makers to put more effort and money into protecting already existing biodiverse forests, which hold high carbon storage potential.

Global CO2 storage capacity may be drastically overstated, study finds
- The storage available for safe carbon storage could be far lower than current estimates, according to a new study.
- Carbon capture and storage (CCS) has been touted as a viable method for drawing billions of tons of CO2 out of the air, typically securing it in rock formations deep underground.
- However, this new analysis suggests that many locations suitable for carbon storage may also pose risks, such as water contamination or earthquakes.
- That finding led the study authors to conclude that the “prudent” available storage is much less than has been estimated.

Setting the record straight on Jurisdictional REDD+: The case of Brazil
- Jurisdictional REDD+ (JREDD+) has been a climate finance mechanism under the UN for nearly two decades. In Brazil, JREDD+ is a public policy approach developed by Brazilian federal and state governments to promote large-scale forest conservation and climate mitigation.
- Emission reductions are measured at the jurisdictional level—not tied to individual properties or collective territories—and generate carbon credits based on verified drops in deforestation and degradation.
- Participation is voluntary and protected by safeguards and law, ensuring communities, farmers, and local actors can opt in or out while retaining land and resource rights. JREDD+ enables access to climate finance from private and public sources, with benefits distributed to rural sectors and credits issued only after independent verification.

Warming triggers unprecedented carbon loss from tropical soils, study finds
- Tropical forests exchange more CO2 with the atmosphere than any other terrestrial biome, meaning that even a relatively small shift in the balance of carbon uptake and release there could have a big impact on global climate. Despite this, research on tropical soil responses to warming has lagged behind.
- In a field experiment in Puerto Rico, researchers used infrared heaters to warm understory plants and topsoil by 4° Celsius. Warming significantly increased soil carbon emissions, but terrain also had a major impact: A warmed plot at the top of a slope showed an unprecedented 204% increase in CO2 emissions after one year.
- Carbon emissions from plots lower on the slope increased between 42% and 59% in response to warming — in line with the results from the only other long-term tropical soil warming experiment to date. However, the upper-slope response represents the largest change in any soil warming experiment conducted globally.
- The new study results add to a growing body of evidence that tropical soils are far more sensitive to warming than previously thought. If elevated tropical soil CO2 releases persist in the long term, it could have dire consequences for Earth’s climate. But the soil biome may adjust over time, so future effects remain unclear.

The carbon market paradox: Steve Zwick on why financing forests is more complicated than it looks
- Steve Zwick’s career has traced the intersection of climate, finance, and media, from Chicago trading pits to international business reporting, Deutsche Welle, Ecosystem Marketplace, and now his Bionic Planet podcast and Carbon Paradox, where he focuses on clarifying the complexities of carbon markets and REDD+.
- He emphasizes that carbon markets are built on probabilities, not certainties, and criticizes both media and advocacy for flattening nuance into oversimplified verdicts. For him, methods evolve through revision, guardrails, and conservative accounting, with avoidance of deforestation often delivering the greatest climate impact.
- Zwick frames forest carbon as payment for services protecting a global commons, not charity, and insists that best practice must be community-led. He warns that skewed scrutiny and polarized narratives risk sidelining a tool that, while imperfect, can mobilize resources quickly until deeper emissions cuts take hold.
- Zwick was interview by Mongabay Founder and CEO Rhett Ayers Butler in September 2025.

Soil carbon: Crucial ally or potential threat to net-zero commitments?
- Earth’s top 2 meters (6 feet) of soil hold 2.5 trillion metric tons of carbon — more than is held in living vegetation and the atmosphere combined. But soil carbon sinks are under threat — global warming could trigger a positive feedback loop that seriously accelerates soil emissions, just as we take steps to decarbonize society.
- The effects of elevated temperature and atmospheric CO₂ on soil carbon have been factored into climate models. But those models don’t currently capture the true complexity of the soil carbon sink, in part because scientists don’t fully understand the mechanisms that influence soil carbon gains and losses.
- Major knowledge gaps urgently need to be addressed: How are long-term soil carbon stores protected from microbial consumption (and CO₂ release)? And how will global warming alter microbial communities, deep soil carbon, and the climate sensitivity of tropical soils (which store a third of global soil carbon)?
- Improved understanding of soil carbon dynamics could offer an opportunity to better manage agricultural and forest soils for carbon sequestration. With proper management, degraded soils could sequester a billion tons of additional carbon annually, making them a key ally in the fight against climate change.

Carbon offset markets are unfair to communities in Borneo & beyond (commentary)
- Recent investigations have found that many carbon offset projects overstate their impact, ignore Indigenous rights, and fail to deliver on promised benefits.
- In tropical forest regions like Malaysian Borneo, only 1% of climate finance reaches Indigenous communities, despite the latter’s proven role in preventing deforestation: in many cases these communities’ stewardship is what makes carbon offset programs possible.
- “The communities who have fought tooth and nail to keep these forests standing are not being rewarded with handsome sums for their efforts. The carbon credits (and the cash) flow primarily to the license holders, not to the Indigenous people who protect these lands,” a new op-ed states.
- This post is a commentary. The views expressed are those of the author, not necessarily of Mongabay.

Old forests, new fires, and a scientific standoff over active management
- Humans have altered the forests of western North America markedly over the past several centuries.
- We’ve suppressed fire, harvested much of the old-growth trees, and built homes and communities within these landscapes, all while anthropogenic climate change has led to hotter and drier conditions.
- Many scientists and forest managers say a set of tools such as prescribed burning and thinning boosts the chances that these forests will survive in a changing landscape.
- But others call for a more hands-off approach, arguing that our “active management” of forests will be detrimental to them and the ecosystems they support in the long run.

Fixing forests or fueling fires? Scientists split over active management
- After years of questionable policies, climate change and growing populations, wildfires have gotten worse in the western U.S., and around the world. That’s driven a push to use tools like thinning and controlled burns to reduce risk and restore natural fire patterns.
- Many researchers argue that the damage inflicted means we need to apply these “active management” tools thoughtfully and tailored to each forest’s conditions.
- But some scientists warn that too much intervention can harm ecosystems, especially old-growth forests.
- The debate has led to scientific and legal battles, ultimately centering on questions about the role people can play in helping forests recover in the face of increasing fire risk.

Global warming is altering storms lightning, impacting tropical forests
- As climate change escalates, intense storms are becoming more common in the tropics and elsewhere, resulting in a variety of forest impacts. Those effects are generating concern among researchers over potentially diminished carbon storage and altered forest composition.
- Increasingly common short-lived convective tropical thunderstorms are a key driver of tree mortality, according to one recent study. Researchers estimate that a combination of high winds and lightning is a major, and often unrecognized, driver of tree death.
- Research suggests convective storms are increasing in the tropics; this could mean more tree death in some regions, such as Latin America. Conversely, there are conflicting data as to whether lightning may decrease or increase in the tropics under climate change, leading to uncertainty about future impacts.
- Beyond the tropics, changing lightning patterns in temperate and boreal forests are linked to increased, often large-scale wildfires that can release vast amounts of carbon dioxide and health-harming particulate matter into the atmosphere.

Reversing damage to the world’s mangrove forests
Mangroves are an important lifeline for biodiversity, climate and coastal communities. Yet they are disappearing 3-5 times faster than total global forest losses, according to UNESCO. On July 26, celebrated as the International Day for the Conservation of the Mangrove Ecosystem, we present recent stories by Mongabay’s journalists on emerging threats to these critical ecosystems […]
From deforestation to renewal: Why reforestation isn’t just about trees
- Sociologist Thomas Rudel explores the social and political forces behind global reforestation, arguing that forest regrowth is rarely automatic and often depends on human decisions and local conditions.
- He critiques top-down climate pledges for failing to engage with smallholder farmers and Indigenous communities, who are frequently the key actors in both forest loss and recovery.
- Rudel highlights the importance of “corporatist coalitions” that link global funders with grassroots actors, enabling more flexible and locally effective forest restoration efforts.
- Rudel spoke with Mongabay founder and CEO Rhett Ayers Butler in July 2025.

Tropical forest roots show strain as changes aboveground filter below
- Tropical forest plant roots have not received as much research attention as aboveground vegetation. This knowledge gap affects our understanding of how rainforests adapt to change, including their ability to capture and store atmospheric carbon.
- An emerging field of research is looking at how root systems respond to global change. New evidence dramatically underlines the outsized importance of tropical forests in the global carbon cycle. Tropical forests represent one of the world’s largest carbon sinks, largely thanks to plant roots, which add carbon to soils.
- Despite the challenge of studying tiny roots hidden underground, researchers are uncovering important insights. Some tropical forests send roots deeper into the soil under dry conditions, possibly seeking moisture, which may aid in drought tolerance. Others seem unable to do this, making them more vulnerable to climate change.
- Recent plant root studies are confirming the immense stress tropical rainforests are under, with conditions changing faster than roots belowground can adapt. Knowing more precisely which forests can, and can’t, tolerate escalating climate change and other stressors could better inform management and conservation decisions.

From apps to Indigenous guardians: Ways we can save rainforests
Deforestation figures can be frustrating to look at, but there are a number of success stories when it comes to protecting tropical forests that we can learn from, Crystal Davis, global program director at the World Resources Institute, says in a recent Mongabay video. “We know what works. We know how to do it,” Davis […]
Bring the forest to the farm or the farm to the forest? Agroforestry faces a dichotomy
- A new comment article published in Nature Climate Change makes the case for more forest-based agroforestry — integrating crops into existing forests — as an underutilized climate and livelihood solution.
- The authors find that there’s a noticeable lack of funding for forest-based methods compared to field-based agroforestry, in which trees are added to pasture and croplands, which they say has led to missed opportunities for carbon storage and biodiversity.
- A lack of consensus and understanding on how to define agroforestry is another factor in the misalignment of intentions and outcomes of agroforestry as a climate solution.
- The authors call on policymakers and scientists to fund and study forest-based agroforestry methods with more rigor, especially in places where people depend on rural livelihoods such as agriculture.

Protecting Tanzania’s Udzungwa Mountains means putting communities at the center of conservation
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. Conservation efforts often falter on the fault line between ecological ambition and human reality. A new initiative in southern Tanzania seeks to bridge that divide, reports contributor Ryan Truscott for Mongabay. The Udzungwa Landscape Strategy (ULS), launched in […]
‘World’s largest’ carbon credit deal under fire as Amazon prosecutors seek repeal
- A Brazilian state was set to close a massive $180 million carbon credit deal, but now faces an escalating legal battle, accused of violating national laws and Indigenous rights, potentially ruining the project.
- Brazil’s Federal Prosecutor’s Office is seeking to nullify the 2024 contract, which sells 12 million carbon credits from Pará to companies like Amazon, Bayer, H&M Group and Walmart.
- Indigenous and Quilombola leaders voice concerns that the program could restrict their access to their land and interaction with nature, undermining inherent rights and deep spiritual connection to the rainforest.
- Widespread accusations over the failure of free, prior, and informed consent for the project highlight ongoing criticism of carbon credit initiatives in Brazil and globally, after scandals involving unapproved use of traditional territories and a loss of confidence in REDD+ projects.

Is rising CO2 really bad for the world’s drylands? Mongabay podcast probes
Increased carbon dioxide emissions since industrialization have accelerated climate change, and its widespread negative impacts have been reported worldwide. But the rising concentrations of CO2 in the atmosphere are also making some parts of our planet greener in what’s called the CO2 fertilization effect. Some politicians claim this effect means more atmospheric CO2 is doing […]
Carbon capture projects promise a climate fix — and a fossil fuel lifeline
- Governments across Southeast Asia are looking at carbon capture and sequestration (CCS) as a way to meet climate targets.
- Projects have been proposed in Malaysia, Indonesia and Thailand, with Japanese companies involved in all three countries.
- Critics say CCS costs too much to be commercially viable, underperforms at capturing carbon, and serves as a diversion from actually reducing emissions.

World Peatland Day: Protecting a crucial carbon sink
Peatlands are one of the world’s biggest carbon sinks. These naturally waterlogged boggy swamps can hold thousands of years’ worth of compressed, partially decomposed vegetation matter — despite covering just 3-4% of Earth’s land surface, they’re thought to store more carbon per area than the world’s forests combined. In honor of World Peatland Day on […]
From local planting to national plan, Belize bets on mangrove recovery
- Mangroves in Belize protect coastlines, are nursery grounds for fish, and store vast amounts of carbon.
- In 2021, the government of Belize committed to restoring 4,000 hectares (nearly 10,000 acres) of mangroves, and protecting an additional 12,000 hectares (nearly 30,000 acres) within a decade, as part of its emissions reduction target under the Paris climate agreement.
- To support this restoration target, WWF Mesoamerica is developing a national mangrove restoration action plan.
- Restoration initiatives are already underway in areas like Gales Point, Placencia Caye and elsewhere.

In Panama, an Indigenous-led project rewrites the rules of reforestation
- Scientists from the Smithsonian Tropical Research Institute are collaborating with local communities in the Ngäbe-Buglé Comarca, a protected Indigenous territory, to foster a ground-up reforestation strategy using native trees and carbon payments.
- The project involves about 30 plots totaling 100 hectares (247 acres) of land, giving participants full ownership of their trees.
- The approach is based on carbon-sequestration data and other scientific metrics collected from Smithsonian’s Agua Salud research site in Colón.
- The work also leans on economic analyses to ensure that reforestation projects can become reliable and sustainable livelihood strategies for Panama’s rural communities.

Brazil bets on macaúba palm to make renewable diesel and aviation biofuel
- Macaúba, a palm tree found across the Americas, is tipped as a new biofuel feedstock to decarbonize transport and aviation. The macaúba palm produces an oil when highly refined that can be made into renewable diesel and sustainable aviation fuel (SAF).
- Bolstered by hype and billions of dollars of investment, companies are planning to plant hundreds of thousands of hectares on reportedly degraded land across Brazil. Firms are also investing in major refining facilities. This macaúba gold rush was triggered by major financial incentives from the Brazilian government.
- Macaúba’s potential green attributes are similar to jatropha, a once promising biofuel feedstock that bombed a decade ago. Macaúba is widespread but currently undomesticated. Whether macaúba plantations can achieve the yield and scale needed to help satisfy the world’s sustainable energy needs remains unknown.
- Industry proponents state that it can be produced sustainably with no land-use change or deforestation. But other analysts say that very much depends on how the coming boom, in Brazil and elsewhere, pans out.

In New Guinea, megadiverse lowland forests are most at risk of deforestation
- Located at the edge of the western Pacific Ocean, New Guinea is a vast island where the biota of Asia and Australasia meet, making it a melting pot of unique plants and animals that occur nowhere else on the planet.
- Development pressure is ramping up across the island, however, opening up landscapes to new roads, industrial logging and agricultural conglomerates pushing biofuel agendas.
- New Guinea’s low-elevation forests, which represent some of the world’s last vestiges of ancient lowland tropical rainforest, are particularly imperiled, according to a new study.
- To avert tragedy, the authors urge policymakers to improve land-use planning systems, focus on retaining intact forest landscapes, and strengthen the rights of the people who live among them.

Republic of Congo’s gold mining boom undermines conservation efforts
The Republic of Congo has one of the lowest deforestation rates in the world, but “uncontrolled gold mining” in recent years could harm the country’s biodiversity, especially in the Sangha region, Mongabay’s Elodie Toto reported in a video published in February. Sangha, located in the country’s north, on the border with Cameroon and the Central […]
Report shows policy gaps in safeguarding the carbon rights of forest communities
- An absence of government legal and policy reforms is impacting the rights of Indigenous, Afro-descendant peoples and local communities associated with carbon programs in 33 countries, according to a recent report.
- More than half of the reviewed countries don’t have carbon trading regulations, and nearly half have no legal provision to recognize the communities’ right to free, prior and informed consent, the report found.
- It emphasizes safeguarding carbon rights to ensure the communities’ consent and rights over decision-making as countries prepare to comply with the Paris Agreement’s market mechanism for trading high-quality carbon credits.
- Although the voluntary carbon market is faring comparatively better in ensuring these rights, researchers say there still remains much to do in terms of addressing grievances and making sure people stay informed.

New report reinforces critical role of Amazonian protected areas in climate fight
- A new report has found that protected areas and Indigenous territories in the Amazon store more aboveground carbon than the rest of the rainforest.
- Protected areas and Indigenous territories were also found to serve as significant carbon sinks between 2013 and 2022, absorbing 257 million metric tons of carbon dioxide.
- Protected areas in Colombia, Brazil, Suriname and French Guiana were found to be significant carbon sinks.
- The report underscores the need to protect these areas that aren’t currently threatened by deforestation as they play a critical role in offsetting emissions from other parts of the forest.

England’s flooded farmlands offer habitat, carbon storage & storm protection
When aging infrastructure failed to protect coastal farmland in southwest England from sea level rise, conservationists chose to embrace the flooding and created a new wetland reserve. Mongabay’s Leo Plunkett and Sandy Watt report in a recent Mongabay video that the newly created marsh has brought a host of benefits to the region. The Steart […]
New research finds substantial peat deposits in Colombia’s conflicted Amazon
- A new study of Colombia’s lowland forests and savannas finds that the nation may have extensive peatlands — organic wetland soils formed over thousands of years — holding as much as 70 years’ worth of Colombia’s carbon emissions. Protecting them from agricultural development is essential to preventing greenhouse gas releases.
- Researchers made peatland estimates by taking sediment cores in 100 wetlands, quantifying peat content, then building a model to predict locales for other peat-forming wetlands using satellite imaging. Peat was found in unexpected ecosystems, such as nutrient-poor white-sand forests, widespread in northern South America.
- Sampling in many locations was only possible due to the ongoing but fragile peace process between the Colombian government and armed rebel groups. In some places, security has already deteriorated and further sampling is unsafe, making this study’s scientific estimate a unique snapshot for now.
- Most Colombian peatlands are remote, but deforestation is intensifying along the base of the Andes, putting some wetlands at risk. Colombia’s existing REDD+ projects have been controversial, but opportunities may exist to combine payments for ecosystem services with peacebuilding if governance and security can be improved.

Agroforestry can reduce deforestation, but supportive policies matter, study finds
- Agroforestry is recognized as a way to boost local biodiversity, improve soils and diversify farming incomes. New research suggests it may also benefit nearby forests by reducing pressure to clear them.
- The study found agroforestry has helped reduce deforestation across Southeast Asia by an estimated 250,319 hectares (618,552 acres) per year between 2015 and 2023, lowering emissions and underscoring its potential as a natural climate solution.
- However, the findings also indicate agroforestry worsened deforestation in many parts of the region, highlighting a nuanced bigger picture that experts say must be heeded.
- Local social, economic and ecological factors are pivotal in determining whether agroforestry’s impacts on nearby forests will be positive or negative, the authors say, and will depend on the prevalence of supportive policies.

Proforestation: The case for leaving trees alone
Founder’s Briefs: An occasional series where Mongabay founder Rhett Ayers Butler shares analysis, perspectives and story summaries. In a quiet corner of northern New York state, the white pines of the Adirondack Forest Preserve rise like sentinels, untouched for more than 125 years. Their silence speaks volumes. These towering trees, some 150 feet (about 46 […]
Betting on future forest carbon storage endangers Paris Agreement targets
- The carbon storage capacity of forests is widely recognized as a crucial factor in curbing global warming and preventing climate catastrophe.
- But a new study finds that the future potential for forest CO2 storage is being overestimated, with global forest health (along with the ability of forests to go on storing carbon) vulnerable to increasing disturbances including wildfires, disease, pests and deforestation.
- Scientists argue that the very real threat of declining forest carbon storage capacity necessitates far faster decarbonization efforts, along with urgent action to monitor and conserve forests, and prevent widespread deforestation.
- Delaying action by as little as five years could incur huge economic costs and jeopardize climate goals, researchers found.

New strategy launched to protect Tanzanian biodiversity hotspot
- A conservation strategy for the next 20 years has been launched to protect Tanzania’s most biologically rich landscape.
- The Udzungwa Mountains are home to rare and endemic plants and animals, including a small population of kipunjis, a genus of monkeys only revealed to the world in 2006.
- Sustainable financing is being sought to fund the conservation strategy and boost livelihoods and social well-being in communities surrounding three core protected areas.
- A key part of the strategy will be the rollout of energy-efficient stoves, seen as a priority by local communities who depend on firewood and charcoal.

Rethinking carbon: The climate movement needs to be a human one, says Paul Hawken
Celebrated author, thinker and entrepreneur Paul Hawken joins Mongabay’s podcast to discuss his new book, Carbon: The Book of Life, and argues that the jargon and fear-based terms broadly used by the climate movement alienate the broader public and fail to communicate the nuance and complexity of the larger ecological crises that humans are causing.

Netherlands’ largest forest biomass plant canceled, forest advocates elated
- Vattenfall, the Netherlands’ third-largest energy producer, has announced it is abandoning plans to build the country’s largest wood pellet burning power plant.
- Forest advocates, who launched a campaign to derail Vattenfall’s plans in 2019, declared victory. They note that burning wood pellets to make energy produces more carbon emissions per unit of energy than coal, despite industry claims that the technology is carbon neutral.
- Increasing scientific evidence shows that burning forest biomass for energy is a false climate solution that increases deforestation and biodiversity loss, while releasing significant carbon emissions at the smokestack — worsening climate change.
- In a recent pivot, EU officials now seem more willing to admit the error of past carbon neutrality claims for wood pellet burning power plants, though they now say those emissions can be eliminated by installing Bioenergy with Carbon Capture and Storage (BCCS) at the facilities — an untested, unready technology, scientists say.

Beyond reforestation, let’s try ‘proforestation’
- “Proforestation” describes the process of allowing existing forests to continue growing without human interference as they achieve their full ecological potential for carbon sequestration and biodiversity.
- Old forests sequester a higher amount of carbon than younger ones, with large, old trees containing the most carbon.
- Many species are old forest specialists, relying on ancient forests for survival. Losing these forests may mean their extinction.

New dams call into question Cambodia’s commitment to REDD+ projects
- Three new irrigation dams have been approved in Cambodia’s Cardamom Mountains, overlapping with two carbon credit projects
- The new developments join five hydropower projects that are already eating into these same forests.
- Communities in the affected area have described the onslaught of dam projects, from which they say they haven’t benefited, as “a war against the forest.”
- Experts say the approval throws into question the Cambodian government’s commitment to carbon credits as a viable climate tool.

Political appointments in Indonesian climate program spark outcry over accountability
- Indonesian Forestry Minister Raja Juli Antoni has appointed seemingly unqualified members of his political party to a key program to reduce greenhouse gas emissions, raising concerns over political favoritism and lack of climate expertise.
- The program is largely funded by Norway and the U.K., with critics warning that donor money is being misused for political appointments rather than forest conservation.
- Norway has called for accountability but remains passive, stating that fund allocation is Indonesia’s responsibility; activists have urged both Norway and the U.K. to audit spending and ensure funds aren’t misallocated.
- Experts warn that time is running out to meet Indonesia’s 2030 climate targets, and that failure could harm Indonesia’s global reputation and worsen climate-related disasters.

Forest biomass growth to soar through 2030, impacting tropical forests
- The forest biomass industry — cutting forests to make wood pellets to be burned in power plants — will continue booming through 2030, says a new report. By then, pellets made in the U.S., Canada, EU and Russia could top 31 million metric tons annually, with those made in tropical nations surging to over 11 million tons yearly.
- The U.K. and EU are forecast to go on burning huge amounts of pellets (more than 18 million metric tons each year by 2030). But Asia will burn even more (27 million tons), with Japan and South Korea expanding use, as Taiwan enters the market.
- Scientists warn that forest biomass burning is unsustainable and produces more CO2 emissions than coal per unit of energy generated. Pellet-making is contributing to deforestation and biodiversity loss in North America, and will increasingly do so in tropical nations, including Vietnam, Brazil, Indonesia and Malaysia.
- Forest advocates continue campaigning against biomass for energy, achieving some hard-won victories. Enviva, the world’s largest biomass producer, went bankrupt in 2024, while South Korea and Japan have taken first steps to reduce subsidies for wood pellets. But the U.K. continues offering millions in subsidies to biomass power plants.

Mangrove deforestation for commodities limits conservation funding in SE Asia
- Southeast Asia’s mangrove forests are still at risk of conversion for oil palm, rice and aquaculture, despite their immense potential for mitigating global biodiversity and climate goals.
- Commodity-driven deforestation and a range of climate change-related risks threaten the long-term survival of 85% of the region’s mangrove forests that could feasibly host carbon credit projects, a new study finds.
- The long-term risks undermine the integrity of blue carbon credits as a potential source of much-needed conservation funding, the study says, ultimately jeopardizing the capacity of mangroves to sequester carbon and provide ecosystem benefits.
- The authors recommend a diverse suite of conservation funding mechanisms rather than relying solely on blue carbon credits, and also urge greater investments in community-led mangrove initiatives.

Many companies meet climate pledges on paper — not on the ground, analyst says
A recent paper in the journal Nature Climate Change concludes there is limited accountability for corporations that fail to achieve their climate change mitigation targets. Lofty sounding initiatives like “carbon neutrality” or “net zero emissions” goals are often met with positive fanfare, but when companies eventually fail to reach them, there are scant consequences. According […]
Forest communities craft recommendations for better ART TREES carbon credit standard
- Fourteen organizations representing Indigenous peoples and local communities across Central and South America submitted recommendations to Architecture for REDD+ Transactions (ART) to demand transparent and inclusive carbon market standards at the jurisdictional level.
- The three major recommendations call for more transparency, inclusivity and accountability in jurisdictional programs of the voluntary carbon market through ensuring rights, free, prior and informed consent, and improved access to fair and equitable benefit-sharing.
- Analyzing the shortcomings of voluntary carbon markets surrounding their standards and certification, the signatories are demanding robust mechanisms that existing standards fail to meet or national legislation fails to implement.
- While opinions on voluntary carbon markets remain largely divided, Indigenous leaders and researchers say properly implementing these recommendations can help the carbon market address a $4.1 trillion gap in nature financing by 2050 and support communities.

Study shows degradation changes a forest’s tree profile and its carbon storage
- In highly deforested landscapes and degraded forests, large-seeded big trees are losing out to opportunistic, fast-growing species, a recent study has found.
- Having examined 1,207 tree species across 271 forest plots in six Brazilian regions in the Amazon Rainforest and Atlantic Forest, the study shows that tree species normally dominating landscapes with a high forest cover seem to be in decline.
- The researchers suggest this is because the relatively large wildlife needed to disperse large seeds disappear early on from human-modified landscapes, allowing trees with smaller seeds, and thus smaller dispersers like birds, to dominate the forestscape.
- As forests become increasingly degraded, they lose their functional characteristics, as soft-wood, fast-growing trees have less ability to store carbon, are less resistant to fire and drought, and generally die younger.

Mining in a forest conservation site clouds Republic of Congo’s carbon credit scheme
- The Republic of Congo set up a REDD+ program in the Sangha and Likouala regions, aiming to reduce deforestation and store carbon from 2020 through to 2024.
- However, in the Sangha region alone, the country’s mining minister has issued at least 79 semi-industrial gold mining and exploration permits since the project began.
- Scientists reviewing images of these mining activities condemn the “reckless” destruction of biodiversity.
- The government says the program stored more than 1.5 million metric tons of carbon in 2020, for which it expects to be paid more than $8 million from the World Bank.

Indonesian president says palm oil expansion won’t deforest because ‘oil palms have leaves’
- Indonesian President Prabowo Subianto has called for the expansion of oil palm plantations, saying any criticism that this will cause deforestation is nonsense because oil palms are trees too.
- The remarks have prompted criticism that they go against the established science showing how plantations have driven deforestation, biodiversity loss and carbon emissions.
- Experts have long called for the palm oil industry to improve yields at existing plantations rather than expand into forests and other ecosystems.
- But the main industry association has welcomed the president’s call, and even the Ministry of Forestry under Prabowo has changed its logo from a forest tree to something that resembles oil palm.

Experts question benefits of Colombian forestation project led by top oil trader
- Trafigura, one of the world’s largest oil traders, has recently invested $100 million to grow 30,000 hectares (74,000 acres) of forest in the eastern plains of Colombia’s Vichada department.
- The company says it aims to plant mixed-species trees, but has seeded primarily eucalyptus trees — nonnative species notorious for hogging water resources.
- That’s prompted skepticism from experts about the project, on top of the fact that the area Trafigura plans to turn into forest was never a forest to begin with.
- Even as the initiative vows to produce and sell carbon credits to slow the climate crisis, the company is simultaneously encouraging oil production and trade in Colombia.

Direct air capture climate solution faces harsh criticism, steep challenges
- Direct air capture — geoengineering technology that draws carbon dioxide from the air, allowing it to be stored in geologic formations or used by industry — is being heavily hyped as a climate solution.
- But as direct air capture (DAC) pilot projects an startups grow in number around the world, fueled by investment and government funding in the U.S. and elsewhere, this proposed climate solution is becoming ever more divisive.
- Critics paint DAC as a costly, ineffective distraction from drastically slashing fossil fuel extraction and emissions. The use of captured carbon by the fossil fuel industry to squeeze ever more oil from wells comes in for particularly sharp criticism.
- Though carbon dioxide removal (CDR) may be needed to help limit the worst impacts of global warming, experts say betting on direct air capture is riddled with challenges of cost and scale. Two hurdles: sourcing sufficient renewables to power DAC facilities, and minimizing carbon-intensive DAC infrastructure.

Satellites and lidar get AI boost to count forest carbon stock worldwide
- A newly launched tool combines satellite images, lidar data and artificial intelligence to estimate carbon stored in forests around the world.
- The Forest Carbon Monitoring tool, developed by Earth-imaging company Planet, trained an AI model using the organization’s archival satellite data and globally available lidar data.
- The model is now being used in conservation efforts as well as in the voluntary carbon market.

Trees live out their lives in surprising ways, massive new study finds
- Trees have more complex life histories than previously thought, which scientists must consider to forecast greenhouse gases in the atmosphere and plan conservation efforts.
- Researchers assembled a dataset of 3.2 million tree measurements, covering more than 1,000 species across North and South America.
- Four “growth strategy” groups emerged, ranging from species that live fast and die young to those that live slow and die old.
- Carbon forecasts should take a more nuanced look at how long carbon is stored in this wide variety of trees, the scientists recommend.

Storing CO2 in rock: Carbon mineralization holds climate promise but needs scale-up
- Carbon mineralization is a process by which gaseous carbon dioxide reacts chemically with certain rock types and transforms into solid carbonate minerals. This natural process is an essential part of the long carbon cycle, which has helped regulate Earth’s temperature for millions of years.
- Mimicking this natural process, subsurface mineralization is a human-induced carbon storage technology, with CO₂ injected directly into in-situ basalt, peridotite and other rock types to accelerate mineralization. In 2012, Iceland’s CarbFix project first demonstrated subsurface mineralization and has stored more than 100,000 metric tons of CO₂ since then.
- Proponents say the technology is safe, verifiable and offers rapid permanent CO₂ storage, giving this sequestration method advantages over other options such as reforestation (where forests can be cut or burn) or conventional geologic storage in sedimentary basins (which requires long-term monitoring for leaks).
- Interest in subsurface carbon mineralization is growing: expanding in Iceland, with test projects in the U.S. and Oman, and others recently announced. But investment in field pilots is needed, plus regulatory and policy support, for scale-up. Unlike other geoengineering methods, this technique seems to pose few environmental problems.

Antarctic krill store massive amounts of carbon in the deep ocean, researchers find
- Antarctic krill trap vast amounts of carbon from the atmosphere in the ocean floor through their sinking fecal pellets, a new study reports.
- The annual amount is similar to that stored by “blue carbon habitats” such as mangroves, seagrass and salt marshes, highlighting the importance of protecting krill.
- Global warming, melting ice and overfishing pose threats to krill, say researchers who call for new fishing policies to conserve them.

New transmission lines cut a Cambodian rainforest sanctuary in half
- Satellite imagery, drone photography and testimony from residents indicate that work has begun on electricity transmission lines that will cut through the heart of Prey Lang Wildlife Sanctuary in order to connect Cambodia’s energy grid with that of Laos.
- A 5.8-kilometer-long (3.6-mile) strip of land has already been cleared inside Prey Lang, indicating that plans are moving forward to run the transmission lines 65 km (40 mi) through the sanctuary.
- Conservationists, and even the former environment minister, recommended alternate routes avoiding the core of the forest, leading one expert to question whether the lines have been deliberately sited to facilitate access by timber traffickers and land investors.

Biodiversity credit approaches multiply as concerns cloud confidence
- In recent years, biodiversity credit projects and the methods to calculate their value have proliferated, seen by some as a way to finance the $700 billion gap in conservation funding identified in the 2022 Global Biodiversity Framework.
- Credits involve payment for measurable outcomes beneficial to nature, ranging from increases in species diversity at a site to securing land rights for Indigenous communities.
- Critics of biodiversity credits have voiced concerns about comparing outcomes across ecosystems, especially if buyers will use the credits for offsetting. They also say focusing on biodiversity credits is a distraction.
- Proponents argue for bolstering biodiversity credit integrity and confidence in the markets to boost demand. Projections by the World Economic Forum suggest the market could reach $7 billion by 2030, though less than $2 million in credits have been sold so far.

Mapping ‘gloop and mud’ sheds light on seabed carbon storage
- Two new reports showing the extent of carbon storage in the marine sediments around the coasts of Canada and the U.K. are helping to build the case for greater protection of the seabed, as part of efforts to mitigate climate change.
- They also highlight some of the threats to this underwater carbon sink, particularly sediment disturbance caused by bottom trawling, a fishing method.
- A new project funded by the U.K.’s Natural Environment Research Council is set to investigate whether or not continued disturbance poses the risk of turning the seabed into a source of CO₂.

Atmospheric methane removal: A promising but challenging climate solution
- Methane is currently responsible for about one-third of global warming. This greenhouse gas is about 80 times more potent than carbon dioxide in terms of its ability to heat up the climate system, though methane molecules only persist in the atmosphere for seven to 12 years before breaking down.
- Methane emissions are a major cause for concern, as they’ve been increasing at record speeds the past five years. At least two-thirds of annual methane emissions now come from human activities, including livestock, agriculture, fossil fuels, and landfills and other waste. Climate change is also increasing methane releases.
- Removing atmospheric methane is a tempting prospect as a climate change-curbing strategy. Multiple geoengineering approaches are being considered, but research remains limited and largely theoretical, while environmental impacts largely remain unknown and underexplored.
- Researchers say methane removal technologies, such as the iron salt method, should be investigated to break down atmospheric methane molecules. But scientists interviewed for this story repeatedly emphasized the most urgent need is to simultaneously make rapid deep cuts to human-caused methane emissions.

Calls for caution as enhanced rock weathering shows carbon capture promise
- Natural rock weathering is a fundamental part of Earth’s carbon cycle but occurs over thousands of years. Enhancing this cycle by spreading fine volcanic rock on agricultural land is a form of geoengineering that could speed up this process and permanently lock away carbon dioxide within decades.
- Startups and research programs are underway across the globe to explore the effectiveness and risks of this climate solution. Spreading rocks such as basalt can sequester carbon and benefit soils, with some studies showing crop yield increases.
- If scaled up, enhanced rock weathering could store gigaton levels of carbon in the future, according to early research. But myriad challenges and uncertainties remain, not least of which is how to accurately calculate and verify how much carbon is being stored, and for how long.
- Some companies are already pushing ahead with deployment, with the idea of profiting from carbon credits, but experts caution that long-term studies are needed to ensure the technique’s efficacy, sustainability and environmental safety.

Study: REDD+ doesn’t work without Indigenous peoples, but fails to engage them
- Climate policies like REDD+ often fail to prioritize Indigenous peoples, undermining their effectiveness in tackling the root causes of deforestation and climate change, according to a recent study.
- The authors propose 12 principles to improve climate policies, based on themes such as supporting Indigenous territorial defense and their rights, encouraging Indigenous-led climate initiatives, and directing climate funding to these populations.
- Indigenous-led initiatives like RIA in the Amazon offer a feasible alternative to REDD+ and emphasize the importance of compensating them for their ecological services; however, they face challenges in getting adequate funding.
- Experts suggest that the lessons learned from REDD+ could be applied to the development of biodiversity credits to help make this emerging climate solution more inclusive from the get-go.

Coffee agroforestry holds promise for smallholder growers in Malawi
- Coffee accounts for only around 11% of Malawi’s agricultural exports, but the crop is a key source of livelihood for thousands of smallholder farmers in the country.
- Small-scale coffee growers have faced challenges such as inadequate inputs, unstable markets and unpredictable rainfall patterns that have impacted yields.
- A coffee agroforestry project by the Food and Agriculture Organization and the Slow Food Coffee Coalition implemented in Malawi and Uganda is promising to tackle some of the challenges and make small-scale coffee farming more profitable.
- The FAO and the SFCC have called for increased adoption of coffee agroforestry as a sustainable agricultural model that redefines the future of coffee farming.

Controversial US marine geoengineering test delayed until next year
- The first-ever field test of ocean alkalinity enhancement in the United States was pushed back to 2025 due to shipping issues. But the geoengineering experiment has also run into public opposition from local environmentalists, commercial fishers and others.
- The test would dump sodium hydroxide (commonly called lye) off the New England coast to study its dispersal as a potential tool for sequestering CO₂.
- Opponents allege this small-scale geoengineering test could harm local wildlife, but researchers say the material will disperse within minutes.
- The scientists say they will also continue to reach out to local communities to alleviate fears over the study.

Cambodian environment minister bans logging at tycoon’s Cardamoms hydropower project
- Cambodia’s environment minister has ordered a ban on forest clearance at a hydropower project site where activists and media, including Mongabay, previously reported indications of illegal logging.
- The Stung Meteuk hydropower project is being developed by a company under Ly Yong Phat, a ruling party senator notorious for a long history of environmentally and socially destructive businesses.
- In April, Mongabay documented the illegal logging operations at the project site, where logging routes had been cut leading into the nearby Phnom Samkos Wildlife Sanctuary.
- Activists have welcomed the order to halt forest clearance, but say they’re skeptical the ban will be enforced against such a powerful figure, noting that timber processing continues at the site.

Clearest picture yet of Amazon carbon density could help guide conservation
- A combination of machine-learning models and satellite readings show that the Amazon Rainforest contains 56.8 billion metric tons of aboveground carbon, or more than one and a half times what humanity emitted in 2023.
- The map is the result of an analysis of data measuring tree cover, tree height and the carbon storage of trees, and yields one of the most precise estimates to date.
- The highest carbon levels are located in the southwest Amazon — specifically southern Peru and western Brazil — and in the northeast Amazon, in countries like French Guiana and Suriname. The findings could help conservationists and policymakers choose more effective conservation strategies in the future.
- The report concluded that, as a whole, the Amazon Rainforest is still acting as a carbon sink rather than a carbon emitter, a key to keeping global temperatures below 1.5°C (2.7°F) and preventing climate change.

Global carbon capture and storage potential way overblown, study finds
A new study finds that the potential for carbon capture and storage is much more limited, by a factor of five or six, than the capacity projected by the United Nations to fight climate change. The U.N.’s Intergovernmental Panel on Climate Change estimates a maximum of 30 gigatons of carbon dioxide can be trapped underground […]
Will we be ready? Geoengineering policy lags far behind pace of climate change
- The history of geoengineering policymaking has been piecemeal over past decades, with U.N. bodies failing to create or implement rigorous binding international regulatory frameworks for geoengineering management, and with academia and think tanks delivering reports and recommendations that offer little definitive detailed regulatory guidance.
- Now, as climate change impacts intensify, the debate over what safe, effective national and international geoengineering policies should look like has intensified among academics, regulatory and advisory bodies and researchers.
- Meanwhile, scientists continue trying to find out if geoengineering (the deliberate altering of global atmospheric or oceanic conditions), can help cool off a dangerously warming planet without triggering harmful effects.
- Some warn geoengineering is too risky and want field research stopped. Others say research is urgently needed so decision-makers can understand geoengineering options and risks, so as to make informed choices. For now, few definitive road signs exist to guide policymaking.

Indigenous communities sidelined for Suriname’s new carbon credit program, critics say
- The government in Suriname announced an offering of the world’s first sovereign carbon credits through the UNFCCC Paris Agreement framework, allowing the country to issue and trade carbon credits with other countries and the private sector.
- But communities living in the forests that made the credits possible say the government rushed the process and didn’t take them into account, leaving many of them in the dark about how the program works and what the benefits are.
- Indigenous and Tribal peoples would receive just 10% of carbon credit revenue from the program, according to government documents reviewed by Mongabay. But the communities don’t understand how it will be distributed.

Logging done sustainably doesn’t have to harm ecosystem services, study finds
- A new study finds that low-intensity logging doesn’t negatively affect a forest’s key ecosystem services such as carbon storage and food availability.
- The study, focused on a selective-logging concession in Gabon, concluded that tree removal rates weren’t high enough to make a dent in ecosystem services.
- Researchers found that while even low-intensity logging did have some impacts on plant diversity, these remained small and largely dissipated in about a decade.
- Experts says forest nations should strive to be “high forest, low deforestation” (HFLD) nations, like Gabon, for which the defined threshold is at least 50% forest cover and less than 0.22% annual deforestation rate.

Blockchain as a carbon market fix: Interview with William ten Zijthoff, Flávia De Souza Mendes & Maximilian Rösgen
- Satellite and blockchain technology could be combined to address the lack of transparency and accountability in the carbon market, according to a recently published report.
- The report suggests that while satellite imagery can provide data in real time, blockchain technology could be used to ensure that the data are accessible, transparent and not tampered with.
- The combination of the two technologies, according to the report, could also be used to improve traceability and ensure compliance with deforestation regulations.
- The complicated nature of blockchain technology, the lack of regulatory infrastructure and high energy consumption are likely causing skepticism and relatively slower uptake for its application in environmental monitoring.

Study highlights environmental and economic benefits of agroforestry for DRC coffee crops
- Growing coffee in agroforestry systems in the Democratic Republic of the Congo (DRC) supports 19 times higher biodiversity and stores twice as much carbon compared with monoculture systems, while maintaining comparable yields.
- But sustainable coffee production in the DRC requires small-holder farmers’ buy-in, considering their immediate economic needs and the local context of extreme poverty.
- Sustainable agroforestry systems are profitable in the long term but face challenges in attracting investment. Experts say responsibility for sustainability should extend to consumers and coffee companies.
- Successful implementation of agroforestry depends on making it beneficial for local farmers, providing additional revenue streams and respecting local ownership and knowledge of the rainforest.

Biomass power grows in Japan despite new understanding of climate risks
- New biomass power plants continue to come online in Japan, requiring an ever-greater quantity of imported fuel. The government’s feed-in tariff scheme, which has been tweaked but not canceled, incentivized these projects.
- Although understanding of forest biomass’s negative environmental and climate impacts is growing in Japan, policy advocates say operators of existing biomass power plants need to pay back construction bank loans, and the government’s refusal to admit its mistake is keeping biomass plants running.
- A major biomass fuel type is wood pellets, which in Japan is presently primarily sourced from plantation forests in Vietnam and primary forests in British Columbia, Canada. While BC ecologists have spoken out against wood pellets, and found allies in Vietnam, the biomass issue has proved challenging for Japan’s forest advocates.
- Though historically a small source of wood pellets for Japan, the growing popularity in Indonesia of pellets for both export and domestic use risks tropical forests there being cleared to make way for biomass energy plantations, NGOs warn.

Are the Amazon’s biggest trees dying? Forest coroners investigate
- As tropical forests are degraded and decline at increasing rates the world over, the fate of these forests’ largest trees remains unknown.
- Big trees store a huge amount of carbon, so assessing their current mortality rates and causes of death (especially due to escalating climate change) is vital to calculating how much tropical forest carbon sinks could decline in the future.
- The Gigante project, getting started in the Brazilian Amazon in June 2024, is initiating an innovative new protocol utilizing detailed drone surveys combined with ground truthing to evaluate tropical big tree mortality.
- The project has begun an identical survey in Panama and will conduct others in Malaysia, Cameroon and at another Amazon location. Knowledge of how tropical big trees are faring could help improve climate model accuracy. A Mongabay reporting team joined the Gigante project in Brazil at the start of this groundbreaking work.

Biochar could play big role in Bhutan’s carbon storage — but it’s news to farmers
- A new study shows that Bhutan has the potential to sequester 68% of its greenhouse gas emissions through biochar, a carbon-rich material made from organic waste that is used to help plants grow.
- The research shows that using crop residue as mulch and biochar can significantly increase yields; however, many farmers in Bhutan do not know about biochar nor do they have access to the raw materials, such as rice husks, necessary for its production.
- While many studies note biochar’s potential for mitigating climate change, some research shows that too much biochar under certain conditions can harm soil, soil organisms and water availability and can cause soil erosion.

As New England forests are razed for solar power, experts urge smarter siting
Every year across a handful of New England states and elsewhere in the U.S., developers cut forests to build utility-scale solar energy projects. Journalist and author Judith Schwartz lives near a forest in the otherwise environmentally progressive state of Vermont, where a company plans to install an 85-acre (34-hectare) solar power project and export the […]
Space mission that maps forests in 3D makes an early comeback
- NASA’s GEDI mission, which maps the Earth’s forests in 3D using lasers, is back in operation from a hiatus, six months earlier than expected.
- Since 2018, GEDI has used spaceborne laser altimeters to help scientists gather data on forest structure, aboveground biomass and carbon stored in forests.
- Following resumption of operations, researchers have used GEDI data along with data from other missions as well as analysis tools to estimate the aboveground carbon stored in protected areas and Indigenous territories in the Amazon Rainforest.

‘Extinct’ trees found in Tanzania spark hope for ecosystem recovery
- Conservationists in eastern Tanzania have found two specimens of a rare tree feared to be extinct.
- Millettia sacleuxii was only known from six specimens in forest reserves that have almost disappeared.
- Thousands of seeds have been collected and seedlings raised, and these are due to be planted out as part of a reforestation project in the Nguru Mountains.
- The two surviving Millettia “mother trees” were found near an area that conservationists hope to soon turn into a wildlife corridor.

‘It is indeed our problem’: Interview with Mário Soares on Brazil’s mangroves
- Mário Soares, a professor of biological oceanography at Rio de Janeiro State University who leads the Mangrove Studies Center (NEMA), has spent more than 30 years studying Brazil’s mangroves, their role in climate change, the effects of oil spills and the importance of mangrove conservation.
- While mangroves fetch a lot of attention in conversations about carbon sequestration, Soares argues that they serve numerous purposes in mitigating climate change; they are also vulnerable to the effects of climate change and must be conserved so that they, in turn, can reduce the vulnerability of the coastal zone.
- Soares also says the carbon market doesn’t solve the problem, only the symptom, because it applies “the market logic,” which created the problem in the first place; meanwhile, we’re not reducing emissions.
- Soares recently spoke to Mongabay about the history and future of Brazil’s mangroves in a video interview.

Hydropower dams further undermine REDD+ efforts in Cambodia
- Five hydropower dams are currently being built in the Cardamom Mountains with reservoirs set to collectively span more than 15,000 hectares (37,065 acres) across protected forests.
- Three of these new dams encroach on forests where REDD+ projects are currently operating, pitting “green” energy infrastructure against conservation goals.
- Residents living nearby one of the dam sites fear that history may repeat as hydropower dams have typically been used to illegally extract valuable timber.

Canada’s 2023 wildfires outsmoked global aviation, yet emissions go uncounted
- Canada’s 2023 wildfires burned an area nearly the size of Ireland, releasing emissions equivalent to four times the global aviation sector.
- Climate change creates longer, more severe fire seasons, leading to a dangerous feedback loop of increasing emissions.
- Canada’s emissions accounting method excludes wildfire emissions from U.N. reports, a practice questioned by some experts.
- Wildfires disproportionately impacted First Nations and Indigenous communities, whose traditional fire management practices could help mitigate risks.

History repeats as logging linked to Cambodian hydropower dam in Cardamoms
- Loggers are targeting protected forests in Cambodia’s Cardamom Mountains using the cover of a new hydropower dam
- The dam is being built by Ly Yong Phat, a wealthy Cambodian tycoon with ties to the top tiers of government and a long history of environmental vandalism in the Cardamoms
- Timber from the Stung Meteuk hydropower dam has already been sold via a government-facilitated auction, but some timber may have been illegally logged
- The dam also overlaps significantly with the Samkos REDD+ project which is still under validation and verification

Better accounting of peat and mangrove carbon to help Indonesia’s climate policies
- A new study shows how Indonesia can improve its carbon accounting for its vast wetland ecosystems of peatlands and mangrove forests.
- The country is home to 14% of the world’s tropical peatlands and 22% of its mangroves, but the deforestation, burning and conversion of these ecosystems is a major contributor to the country’s overall emissions.
- Researchers have identified gaps in the country’s current greenhouse gas accounting system that, if closed, could yield more accurate and transparent data to inform climate policies and emissions reduction goals.
- Indonesia has set itself a 2030 deadline to turn its forests into a net carbon sink and slash emissions by up to 43% as part of its commitment to the 2015 Paris climate deal.

Can iron fertilization of the oceans help solve the climate crisis? (commentary)
- In response to climate change, several carbon dioxide removal approaches involving the marine environment are being studied, with ocean iron fertilization being among those with the greatest potential, according to the U.S. National Academies of Sciences.
- The introduction of iron into ocean regions that are iron-limited stimulates the growth of phytoplankton, which play a pivotal role in carbon sequestration, and while critics have long pointed out that such fertilization could cause wide ranging ecological consequences, a number of researchers are pursuing it with new energy.
- “It is important to conduct research and hold public deliberations to explore if iron fertilization could be effectively and safely done, and whether coastal communities and rights holders might actually want it,” a new op-ed argues.
- This post is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

As Big Tech eyes the carbon market, will it work this time?
- Tech giants Meta, Microsoft, Google and Salesforce have announced the launch of an alliance that aims to invest in nature-based carbon removal projects.
- The Symbiosis Coalition has promised to purchase carbon credits worth 20 million metric tons of carbon dioxide by 2030.
- The collaboration comes at a time when the voluntary carbon market has faced increasing scrutiny over allegations of greenwashing, human rights abuses and lack of transparency.
- The coalition says that it will focus initially on afforestation, reforestation and revegetation, and that it has worked with independent experts to establish guidelines to ensure accountability and benefit sharing with local communities.

‘Non-market’ solutions to deforestation need more support, advocates say
- In a report released May 29, three environmental groups called for a shift away from carbon markets and toward “non-market” solutions to deforestation.
- The Paris Agreement has a clause calling for such solutions, which the groups said could include financing for Indigenous groups, payment for ecosystem services, and debt relief.
- The report criticized carbon markets, saying incentives for brokers and project developers are misaligned with global environmental priorities.

Are carbon credits another resource-for-cash grab? Interview with Alondra Cerdes Morales & Samuel Nguiffo
- Indigenous and traditional communities around the world are increasingly being recognized for their stewardship of forests.
- That’s led to their lands being seen as prime targets for carbon credit projects, the idea being that the carbon sequestered here can be sold to offset emissions elsewhere.
- While some Indigenous communities have welcomed these projects and the funds they bring in, others say they’re just another example of the monetization of natural resources that’s driving the climate crisis in the first place.
- Mongabay interviewed two leading Indigenous voices on both sides of the debate, who say the issue is a deeply nuanced one that carries implications for Indigenous land rights, culture and sustainability.

Research shows the Caatinga is Brazil’s most efficient carbon capture biome
- Studies found that for every 100 metric tons of CO2 absorbed by dried-out forests in the semiarid area of Brazil’s northeasern region, 45-60 metric tons do not return to the atmosphere; in the Amazon Rainforest, the balance between carbon absorption and release ranges from 2-11%, compared with 23% in the Cerrado biome.
- According to researchers, the Caatinga’s vegetation stores 8,677 metric tons of carbon per square mile [3,350 per square kilometer], which can be released in the event of deforestation — a problem that increased by 2,500% from 2019 to2022, making the Caatinga Brazil’s third-most deforested biome.
- The solutions suggested to preserve the Caatinga include social carbon credit programs, new conservation units, and degraded areas recovered through agroecology.

Indonesian company defies order, still clearing peatlands in orangutan habitat
- Indonesian Pulpwood producer PT Mayawana Persada is continuing to clear peatlands on critical Bornean orangutan (Pongo pygmaeus) habitat, despite a government order to stop clearing.
- An NGO coalition analysis found that 30,296 hectares (74,900 acres) of peatland, including 15,560 hectares (38,400 acres) of protected lands, had been converted as of March; 15,643 hectares (38,700 acres) of known Bornean orangutan habitat were cleared between 2016 and 2022.
- Conservationists are calling on the Ministry of Environment and Forestry to revoke the company’s permits.

UK’s Drax targets California forests for two major wood pellet plants
- Golden State Natural Resources (GSNR), a California state-funded nonprofit focused on rural economic development, along with the U.K.’s Drax, a global maker of biomass for energy, have signed an agreement to move ahead on a California project to build two of the biggest wood pellet mills in the United States.
- The mills, if approved by the state, would produce 1 million tons of pellets for export annually to Japan and South Korea, where they would be burned in converted coal power plants. The pellet mills would represent a major expansion of U.S. biomass production outside the U.S. Southeast, where most pellet making has been centered.
- GSNR promotes the pellet mills as providing jobs, preventing wildfires and reducing carbon emissions. California forest advocates say that cutting trees to make pellets —partly within eight national forests — will achieve none of those goals.
- Opponents note that the U.S. pellet industry is highly automated and offers few jobs, while the mills pollute rural communities. Clear-cutting trees, which is largely the model U.S. biomass firms use, does little to prevent fires and reduces carbon storage. Pellet burning also produces more emissions than coal per unit of energy produced.

Mangrove forestry only sustainable when conservation zones respected: Study
- The need to preserve mangroves and the ecosystem services they sustain, while also providing for the social and economic needs of the people who depend on them, is one of coastal conservation’s greatest conundrums.
- New research based on long-term data from a mangrove production forest in Malaysia suggests that, in some cases, it is possible to reconcile mangrove protection with resource needs — but only when the correct management is implemented and enforced.
- The study highlights the need for well-protected conservation areas within forest production landscapes to boost natural forest regeneration, sustain wildlife and balance overall levels of carbon storage.
- The authors also warn that management models that seek to maximize profits at the expense of such sensitive conservation areas could undermine the resilience of the overall landscape and diminish sustainability over time.

AI model maps global tree canopy heights in hi-res, with carbon counting in mind
- Scientists have used high-resolution satellite images to create a map of global canopy heights, and to also develop an AI model that can predict canopy heights.
- Tech company Meta collaborated with nonprofit organization World Resources Institute to develop the open-source map and model.
- While the map aims to establish and serve as a baseline for conservation initiatives, the AI model could be used to predict canopy heights in areas where high-quality data aren’t available.
- Canopy height is an important indicator of forest biomass and aboveground carbon stock, and is used to measure the progress of forest restoration efforts.

Protected areas bear the brunt as forest loss continues across Cambodia
- In 2023, Cambodia lost forest cover the size of the city of Los Angeles, or 121,000 hectares (300,000 acres), according to new data published by the University of Maryland.
- The majority of this loss occurred inside protected areas, with the beleaguered Prey Lang Wildlife Sanctuary recording the highest rate of forest loss in what was one of its worst years on record.
- A leading conservation activist says illegal logging inside protected areas is driven in part by demand for luxury timber exports, “but the authorities don’t seem to care about protecting these forests.”
- Despite the worrying trend highlighted by the data, the Cambodian government has set an ambitious target of increasing the country’s forest cover to 60% by 2050.

As fires ravaged Indonesia in 2023, some positive trends emerged, data show
- Indonesia’s 2023 fire season saw 1.16 million hectares (2.87 million acres) of land and forest go up in flames, and while this was five times higher than in 2022, experts highlight a positive trend.
- The fires were exacerbated by an intense El Niño weather system, unlike in 2022; the last time similar conditions prevailed, in 2019, the area affected by fires was much larger, suggesting fire mitigation efforts may be working.
- Most of the burning occurred in scrubland and areas of degraded forest rather than in intact forests, meaning greenhouse gas emissions from the burning were also much lower than in 2023.
- But a worrying trend highlighted by the numbers is that severe fires are now occurring in four-year cycles, intensified and exacerbated by the impacts of a changing climate.

Tropical forest loss puts 2030 zero-deforestation target further out of reach
- The overall rate of primary forest loss across the tropics remained stubbornly high in 2023, putting the world well off track from its net-zero deforestation target by 2030, according to a new report from the World Resources Institute.
- The few bright spots were Brazil and Colombia, where changes in political leadership helped drive down deforestation rates in the Amazon.
- Elsewhere, however, several countries hit record-high rates of forest loss, including the Democratic Republic of Congo, Bolivia and Laos, driven largely by agriculture, mining and fires.
- The report authors call for “bold global mechanisms and unique local initiatives … to achieve enduring reductions in deforestation across all tropical front countries.”

Land tenure lesson from Laos for forest carbon projects (commentary)
- Laos has lost approximately 4.37 million hectares of tree cover since 2001, and some suggest forest carbon projects could be a solution.
- However, these haven’t had a good track record in the nation, in part due to its land tenure rules — land is owned by the state but largely used by local communities through customary tenure arrangements — leading to misunderstandings between companies, communities, and government agencies.
- “Forest carbon projects should continuously engage in capacity-building for local communities and authorities, thus creating an enabling environment for just benefit-sharing, securing land tenure, and the sustainability of these projects to reduce emissions over the long term,” a new op-ed argues.

Enviva bankruptcy fallout ripples through biomass industry, U.S. and EU
- In March, Enviva, the world’s largest woody biomass producer for industrial energy, declared bankruptcy. That cataclysmic collapse triggered a rush of political and economic maneuvering in the U.S. (a key wood pellet producing nation), and in Europe (a primary industrial biomass energy user in converted coal plants).
- While Enviva publicly claims it will survive the bankruptcy, a whistleblower in touch with sources inside the company says it will continue failing to meet its wood pellet contract obligations, and that its production facilities — plagued by chronic systemic manufacturing problems — will continue underperforming.
- Enviva and the forestry industry appear now to be lobbying the Biden administration, hoping to tap into millions in renewable energy credits under the Inflation Reduction Act — a move environmentalists are resisting. In March, federal officials made a fact-finding trip to an Enviva facility and local communities who say the firm is a major polluter.
- Meanwhile, some EU nations are scrambling to find new sources of wood pellets to meet their sustainable energy pledges under the Paris agreement. The UK’s Drax, an Enviva pellet user (and also a major pellet producer), is positioning itself to greatly increase its pellet production in the U.S. South and maybe benefit from IRA subsidies.

Report links pulpwood estate clearing Bornean orangutan habitat to RGE Group
- NGOs have accused PT Mayawana Persada, a company with a massive pulpwood concession in Indonesian Borneo, of extensive deforestation that threatens both Indigenous lands and orangutan habitat.
- In a recent report, the NGOs also highlighted links that they say tie the company to Singapore-based paper and palm oil conglomerate Royal Golden Eagle (RGE).
- RGE has denied any affiliation with Mayawana Persada, despite findings of shared key personnel, operational management connections, and supply chain links.
- The report also suggests the Mayawana Persada plantation is gearing up to supply pulpwood in time for a massive production boost by RGE, which is expanding its flagship mill in Sumatra and building a new mill in Borneo.

Are biodiversity credits just another business-as-usual finance scheme?
- There’s a new emerging innovative finance scheme to support biodiversity conservation: voluntary biodiversity credits. These are meant to be purely voluntary, “positive investment” in nature by the private sector and, in theory, should not be used to offset damage elsewhere.
- But several Indigenous and environmental groups and researchers worry that, like the voluntary carbon credit market, a voluntary biodiversity market could end up being used for offsets, allowing companies and governments to continue business as usual.
- Critics also say there is lack of a clear demand for such credits from the private sector, and a voluntary biodiversity credit market won’t be a sustainable solution at a global scale.
- Indigenous and local communities have the potential to financially benefit from these biodiversity credit projects, which are likely to target their lands. But experts point out the need to first fix several fundamental problems that have already emerged in the carbon credit market, from the lack of land rights among Indigenous communities to unscrupulous middlemen, unjust contracts and dilution of funds.

UN probes controversial forest carbon agreement in Malaysian Borneo
- The government of Sabah state in Malaysian Borneo will continue to move forward with an opaque nature conservation agreement despite concerns raised by the United Nations.
- In a letter, the U.N. calls in question the transparency of the agreement and the state’s approach to the human rights law principle of free, prior and informed consent.
- The agreement was signed by state officials and a representative of a Singaporean company in 2021. Shortly after news of the deal became public, some Indigenous groups in the state said they hadn’t been consulted or informed about the deal covering 2 million hectares (4.9 million acres) of the state’s forests.
- The U.N. letter was written by a group of “special procedures experts” with mandates established by the U.N. Human Rights Council, including the special rapporteurs on the rights of Indigenous peoples, on human rights and the environment, and on the right to development.

Chocó land deal shows flaws in Ecuador’s forestry incentive program
- A conflict over thousands of hectares of the Andean Chocó bioregion of northwestern Ecuador — now enmeshed in a decade-long legal battle — shows that the country’s Socio Bosque program is susceptible to potential corruption and political dealmaking, activists in the area claim.
- Over 9,000 hectares (22,239 acres) were stolen from local communities through an illegal land sale that was then used to benefit from the Socio Bosque program, critics say.
- Complaints filed to the Ministry of Environment have led to multiple inspections of the land, and the person who collected Socio Bosque payments was ordered to return $152,364.

New report details rights abuses in Cambodia’s Southern Cardamom REDD+ project
- Human Rights Watch has detailed forced evictions, property destruction and violence against Indigenous communities living within a REDD+ carbon offset project area in southwest Cambodia.
- Trade of carbon credits from the Southern Cardamom REDD+ project were suspended last year amid similar allegations, and the project’s carbon certifier recently announced it’s expanding its ongoing investigation.
- Residents told Mongabay that Wildlife Alliance, the NGO that manages the project, has effectively outlawed their traditional methods of farming and livelihood, including restricting their access to sustainable forest products.
- Wildlife Alliance has denied the allegations, suggesting HRW has an agenda against carbon offsetting projects, but says it’s making improvements in response to the allegations.

Breadfruit’s low carbon storage could be offset by fast growth, study finds
- Breadfruit, a perennial tropical tree that produces large, carbohydrate-rich fruit, has been put forward by advocates as a climate solution as well as a way to strengthen food security; but the carbon storage potential of breadfruit has never before been investigated.
- In a new study, researchers from the University of Hawai‘i at Mānoa found that in orchards, breadfruit’s carbon storage abilities are relatively low compared with other broadleaf trees in wet environments.
- However, the authors say breadfruit compensates for this with a fast growth rate and may be better served as building blocks for agroforestry plots that can sequester even more CO₂; more research is required to understand the full potential of breadfruits in a sustainable system.

Forest and climate scientists fear Biden delay on mature forest protection
- More than 200 forest ecologists and top climate scientists, including Jim Hansen and Michael Mann, have written the Biden administration urging it to quickly move forward on the president’s commitment to protect old-growth and mature forests on federal lands.
- The scientists made an urgent plea for an immediate moratorium on logging federal forests with trees 100 years old or older, many of which remain vulnerable to logging and dozens of timber sales nationally. They also asked for the establishment of substantive federal management standards to protect those forests.
- Federally owned old-growth and mature forests play an outsized role in storing carbon, offering a vital hedge against escalating climate change.
- At stake are 112.8 million acres (45.6 million hectares) of old-growth and mature forest on federal lands, according to a 2023 U.S. Forest Service and Bureau of Land Management inventory — an area larger than California. Less than a quarter of those forests are currently protected against logging.

Megafires are spreading in the Amazon — and they are here to stay
- Wildfires consuming more than 100 square kilometers (38 square miles) of tropical rainforest shouldn’t happen, yet they are becoming more and more frequent.
- Because of its intense humidity and tall trees, fire does not occur spontaneously in the Amazon; usually accidental, forest fires are caused by uncontrolled small fires coming from crop burning, livestock management or clear-cutting.
- Scientists say the rainforest is becoming increasingly flammable, even in areas not directly related to deforestation; fire is now spreading faster and higher, reaching more than 10 meters (32 feet) in height.

Freeze on Russian collaboration disrupts urgently needed permafrost data flow
- Accelerating Arctic warming threatens to thaw more and more carbon-rich permafrost and release vast amounts of greenhouse gases into the Earth’s atmosphere, but scientists don’t know when such a tipping point event might occur.
- The potential for large and abrupt permafrost emissions adds urgency to better understanding the factors that could turn permafrost from a carbon sink into a carbon source.
- However, more than half of all Arctic permafrost lies under Russian soil, and a two-year freeze on collaborations between Russian scientists and the international scientific community — prompted by the Russian invasion of Ukraine on Feb. 24, 2022 — is disrupting data flows and hamstringing the polar research community.
- Despite an uncertain geopolitical landscape, scientists are determined to close the data gap with work-arounds such as pivoting to “proxy” field sites, ramping up remote sensing with AI, and mining archived data for new insights. But reintegrating Russian research with other Arctic research is a priority of the scientific community.

Freeing trees of their liana load can boost carbon sequestration in tropical forests
- Lianas are woody, vining plants, many of which thrive in areas where forest has been disturbed — often to the detriment of the trees they use to climb towards the sun.
- New research shows that liana cutting is a low-cost natural climate solution that can boost the amount of carbon absorbed by a tree.
- The study’s results indicate that freeing just five trees per hectare of their liana load could remove 800 million tons of C02 from the atmosphere over a 30 year period if applied across 250 million hectares of managed forest.
- Liana cutting is also seen as a way for foresters and conservationists to work together, improving both the forest’s power to sequester carbon and the quality of the timber that is being logged, as well as a way to generate income for local communities.

How much carbon does ocean trawling put into the atmosphere?
- New research suggests that bottom trawling stirs up large amounts of carbon from the seabed and releases 55-60% of this carbon into the atmosphere within nine years.
- This amount of carbon is nearly double the annual emissions from the combustion of fuel by the entire global fishing fleet of about 4 million vessels, the study suggests.
- The authors say that the remaining 40-45% of the carbon would remain dissolved in the water, contributing to ocean acidification.
- However, this study has drawn criticism for potentially overestimating the amount of seabed carbon that trawling releases.

Study: Burning wood pellets for energy endangers local communities’ health
- A new peer-reviewed study quantifies broadly for the first time the air pollution and public health impacts across the United States from both manufacturing wood pellets and burning them for energy.
- The study, said to be far more extensive than any research by the US Environmental Protection Agency, finds that U.S. biomass-burning facilities emit on average 2.8 times the amount of pollution of power plants that burn coal, oil or natural gas.
- Wood pellet manufacturers maintain that the harvest of forest wood for the purpose of making wood pellets to burn for energy remains a climate-friendly solution. But a host of studies undermine those claims.
- The Southern Environmental Law Center says the study provides new and rigorous science that could become a useful tool in arguing against the expansion of the wood pellet industry in the United States.

Markets and forests: 7 takeaways from our series on the forest carbon trade
This is the wrap-up article for our five-part series on forest carbon credits and the voluntary market. Read Part One, Part Two, Part Three, Part Four and Part Five. Mongabay recently published a five-part series on the carbon trade and its use as a tool to address climate change. The exchange of carbon credits, typically […]
The future of forest carbon credits and voluntary markets
- Observers predicted that 2023 would be a “make-or-break” year for voluntary carbon markets and “an inflection point” for their role in addressing climate change and global deforestation.
- Amid criticisms around carbon accounting, carbon neutrality claims, and issues with forest communities, governance bodies say they’ve worked to increase consistency and “integrity” for the voluntary carbon market and specifically the forest conservation strategy known as REDD+.
- Concerns remain from a variety of observers, including those who say the focus of credit-buying companies should be on eliminating their carbon emissions from across their entire suite of operations.
- But proponents of markets say that while decarbonizing is absolutely necessary to minimize the rise in global temperatures, the carbon trade allows for the mitigation of pesky residual emissions that it’s either impossible or too expensive to get rid of at this point.

Leveraging the hypothetical: The uncertain world of carbon credit calculations
- Criticisms of the voluntary carbon trade and forest conservation strategies like REDD+ have centered largely on the carbon accounting methods used to calculate credits.
- Each credit traded on voluntary markets is supposed to represent the reduction, avoidance or removal of 1 metric ton of carbon dioxide from the atmosphere.
- But recent science has raised questions about how REDD+ and other types of project figure out the number of tons of emissions saved.
- The process relies on establishing a baseline rate of deforestation against which a project’s emissions-reducing or -removing success is measured. But critics say the process can be faulty and that the conflicts of interest of the parties involved in setting the baseline have not been addressed until recently.

‘Cowboys’ and intermediaries thrive in Wild West of the carbon market
- A host of different players have crowded into the voluntary carbon trade as its value has grown.
- Motivated by the potential for profit, a concern for climate change or some combination of the two, these companies and organizations link the credits generated by projects, such as those that fit in the forest conservation scheme known as REDD+, with buyers, often companies and individuals in the Global North looking to compensate for their climate impacts.
- Some groups say they help shoulder the burden of tasks like marketing so that the communities and project staff on the ground can focus on the “change-making work.”
- But others, sometimes called “carbon cowboys,” seem interested in the money to be made from trading carbon. Some have faced allegations that they don’t bring the necessary expertise to their work, or that they don’t adequately inform local communities about the intended projects and the potential pitfalls.

Do carbon credits really help communities that keep forests standing?
- Communities play a critical role in REDD+, a forest conservation strategy that aims to reduce emissions that can be sold as credits to raise money for forest protection.
- REDD+ projects often include components for the benefit of the communities, such as a focus on alternative livelihoods and provision of health care and education.
- But reports that REDD+ communities have faced abuses and rights violations have emerged recently in connection with high-profile REDD+ projects.
- Several Indigenous-led organizations have voiced their support for REDD+ because, they say, it provides an avenue to fund their climate-related conservation work, while other groups say it’s not the answer.

False claims of U.N. backing see Indigenous groups cede forest rights for sketchy finance
- Several companies registered in Latin American countries claiming to have U.N. endorsement have persuaded Indigenous communities to hand over the economic rights to their forests for decades to come, a Mongabay investigation has found. The companies share commercial interests across various jurisdictions, and have not been able to demonstrate experience in sustainable finance projects.
- Indigenous communities in Peru, Bolivia and Panama were promised jobs and local development projects in exchange for putting on the market more than 9.5 million hectares (23.5 million acres) of forests. According to community sources, the claims of U.N. backing were the main selling point for agreeing to put their forests on the market. All three U.N. entities cited by the companies have rejected any involvement.
- Mongabay has found that the methodology employed for valuing natural capital has not been used before; there are no public details regarding its scientific and technical basis; and the company that created the methodology refused to share information about it.
- Experts have raised concerns that a lack of regulation in the fast-growing sustainable finance industry is allowing abuses against communities that act as guardians for critical ecosystems.

Forest carbon credits and the voluntary market: A solution or a distraction?
- Voluntary carbon markets and forest carbon credits have faced widespread criticism that reached a zenith in 2023.
- Media reports detailed concerns about their dubious climate benefits, respect for communities and land rights, and their use by Global North companies to avoid the difficult task of decarbonizing their operations.
- Supporters of forest conservation strategies like REDD+ say that they can and should play a role, as healthy forests can absorb a significant amount of atmospheric carbon. They also say REDD+ brings much-needed funding to protect and restore forests, not only for their carbon, but because of the biodiversity and communities they support.
- As 2023 draws to a close, and with it the U.N. climate conference in Dubai (COP28), proponents of the voluntary carbon trade are working to increase the “integrity” of markets in ways they hope make them a viable tool to deal with climate change.

Indigenous-led coalition calls for moratorium on terrestrial carbon trade
- The Pathways Alliance for Change and Transformation (PACT), a coalition of Indigenous, community and nonprofit organizations, published a paper in September 2023 calling for a moratorium on the forest carbon trade out of concern for the rights of Indigenous peoples and local communities.
- PACT says a pause in selling carbon credits is needed until protections for the land rights of these communities are laid out “explicitly, proactively, and comprehensively.”
- In December at the U.N. climate conference in Dubai, carbon markets experienced a setback after negotiators failed to agree on texts to articles in the 2015 Paris climate agreement meant to guide the carbon trade.

The year in rainforests: 2023
- The following is Mongabay’s annual recap of major tropical rainforest storylines.
- While the data is still preliminary, it appears that deforestation declined across the tropics as a whole in 2023 due to developments in the Amazon, which has more than half the world’s remaining primary tropical forests.
- Some of the other big storylines for the year: Lula prioritizes the Amazon; droughts in the Amazon and Indonsia; Indonesia holds the line on deforestation despite el Niño; regulation on imports of forest-risk commodities; an eventful year in the forest carbon market; rainforests and Indigenous peoples; and rampant illegality.

New dams in Cambodia pit ‘green’ hydropower against REDD+ project
- The recent approval of two hydropower dams in Cambodia’s Cardamom Mountains could undermine a REDD+ carbon project in the area.
- The Southern Cardamom REDD+ Project relies on keeping the forests in this region standing — a goal researchers say is “completely incompatible” with the forest clearing and flooding necessitated by the new dams.
- The lack of transparency inherent in both the carbon market and the Cambodian government means that the fate of the Cardamoms remains unclear for now.

New tool aims to make nature-based solutions projects in SE Asia a better sell
- A coalition of conservation NGOs has introduced a new tool aimed at helping local communities in Southeast Asia apply more effectively for funding for nature-based solutions projects.
- The group, which includes Conservation International and The Nature Conservancy, says the region has massive potential for projects to absorb carbon and protect wildlife, but that access to funding remains a huge gap.
- The new NbS tool is designed to help project managers put together project documentation that includes data analysis that should make it easier for donors to immediately identify the benefits from the projects being proposed.
- The tool isn’t limited to helping package nature-based solutions projects; proponents say it can also be used to put together the paperwork needed for other community-led initiatives that require data documentation and analysis.

In Laos, forest loss and carbon emissions escalate as agriculture intensifies
- Shifting cultivation is expanding into intact forest frontiers in Laos, triggering a spike in associated carbon emissions, according to a new study based on satellite data.
- As the dominant land use type in Laos, shifting cultivation has affected roughly one-third of the country’s total land area over the past three decades, the study says.
- The study also highlights how fallow land, a vital carbon store in Laos, is increasingly undermined by farming practices characterized by shorter fallow periods.
- The authors say their data can be used by policymakers to design programs that support more sustainable forms of shifting cultivation. Experts urge that such interventions sensitively consider why remote communities might be forced to transition away from traditional, subsistence-based farming toward intensified systems.

Tropical deforestation increases even as a few hotspots see respite, new data shows
- Emissions from deforestation in tropical forests rose by 5% in 2022, even as temperate forests strengthened their role as carbon sinks, according to data from a carbon mapping tool developed by nonprofit CTrees.
- According to the data, emissions from deforestation saw a dip in Indonesia and the Congo Basin in 2022; in Brazil, however, emissions continued to rise through 2022, and only started dropping this year.
- The JMRV platform uses satellite imagery and machine learning to map forests and non-forest lands around the world to monitor forest cover, carbon stocks and emissions.
- In addition to broader global data, the tool can also help local jurisdictions monitor and verify their carbon stocks to keep track of their emissions-reduction progress under the Paris climate agreement.

Community tropical forest management linked to social & environmental benefits: Study
- A study shows that forests in 15 tropical countries across Africa, Asia and Latin America managed by Indigenous peoples and local communities are associated with improved outcomes for carbon storage, biodiversity and forest livelihoods.
- The study finds that the positive outcomes were most likely observed when formal management institutions were in place and Indigenous and local communities had influence in defining their rights and roles in forest use and management.
- The findings suggest that governance reforms, like supporting Indigenous and local community rights or roles to manage forests, can play a role in supporting both human and environmental goals in tropical forested landscapes.
- However, giving local people formal rights is just a starting point, the lead author says; other procedures and support need to be in place to determine whether people actually get those rights and if they are able to use them to good effect.

Amazon deforestation declines but fossil fuels remain contentious, COP28 shows
- COP28 celebrates the strong downward trend in deforestation in the Amazon over the last year, but also reveals a conflict between Amazonian nations over fossil fuels.
- Colombia has stopped all new oil exploration contracts in a bid to eliminate dependency on the fossil fuel economy. On the other hand, Brazil announced plans that could make it the world’s fourth-largest oil producer by the end of this decade.
- Indigenous groups who live and depend on the Amazon Rainforest lament that they haven’t been heard or involved in important decision-making during COP28 that would ultimately impact them.
- Experts say that international finance is “fundamental” for climate action, and while this theme has been on the table at COP28, there has been no tangible action that would meet the scale required to preserve the Amazon Rainforest.

Despite progress, small share of climate pledge went to Indigenous groups: report
- A report from funders of a $1.7 billion pledge to support Indigenous peoples and local communities’ land rights made at the 2021 U.N. climate conference found that 48% of the financing was distributed.
- The findings also show that only 2.1% of the funding went directly to Indigenous peoples and local communities, despite petitions to increase direct funding for their role in combating climate change and biodiversity loss.
- This is down from the 2.9% of direct funding that was disbursed in 2021.
- Both donors and representatives of Indigenous and community groups call for more direct funding to these organizations by reducing the obstacles they face, improving their capacity, and respecting traditional knowledge systems.

Carbon credit certifier Verra updates accounting method amid growing criticism
- The world’s largest carbon credit certifier, Verra, has overhauled its methods for calculating the climate impacts of REDD projects that aim to reduce deforestation.
- REDD stands for reducing emissions from deforestation and forest degradation.
- The emissions reductions from these projects can be sold on the voluntary carbon market to individuals and companies, which proponents say provides a vital stream of funding for forest conservation.
- The update changes the process for calculating deforestation baselines, which help determine how effective a project has been at reducing forest loss and keeping the carbon those trees contain out of the atmosphere.

U.N. carbon trading scheme holds promise and peril for tropical forests
- Suriname is one of the first countries to announce it aims to use emissions reduction results through a forest conservation scheme known as REDD+ to trade almost 5 million carbon credits underArticle 6 of the Paris Agreement.
- Article 6 of the agreement establishes a framework for emissions trading through market and non-market mechanisms, which are poised to play a central role in delivering the pledged emissions cuts of many countries.
- Around 85% of countries that signed the 2015 Paris Agreement have indicated their intent to use international carbon markets to achieve their updated or new emissions reduction targets.
- While some experts see Article 6 as a valid way to channel finance into REDD+, others are wary that it could compromise the integrity of the system.

Enviva, the world’s largest biomass energy company, is near collapse
- The forest biomass energy industry took a major hit this month, as Enviva, the world’s largest producer of wood pellets — burned in former coal power plants to make energy on an industrial scale — saw catastrophic third quarter losses. Enviva’s stock tanked, its CEO was replaced and the company seems near collapse.
- Founded in 2004, Enviva harvests forests in the U.S. Southeast, with its 10 plants key providers of wood pellets to large power plants in the EU, U.K., Japan and South Korea — nations that use a scientifically suspect carbon accounting loophole to count the burning of forest wood as a renewable resource.
- A former manager and whistleblower at Enviva told Mongabay in 2022 that the company’s green claims were fraudulent. Last week, he said that much of Enviva’s downfall is based on its cheaply built factories equipped with faulty machinery and on large-scale fiscal miscalculations regarding wood-procurement costs.
- How the firm’s downfall will impact the global biomass for energy market, and worldwide pellet supply, is unknown. European and Asian nations rely on Enviva pellets to supply their power plants and to meet climate change goals, with the burning of forests to make energy erroneously claimed as producing zero emissions.

Control of Africa’s forests must not be sold to carbon offset companies (commentary)
- A forest carbon deal between Blue Carbon and the nation of Liberia would give the company exclusive rights to control 10% of the nation’s land mass for 30 years.
- Blue Carbon has also signed MOUs for similar deals with Tanzania and Zambia (and others) and combined with the Liberia deal, the land controlled by the company in these three African nations represents an area the size of the whole of the United Kingdom.
- “Carbon colonialism is a false solution to the climate crisis,” a new op-ed states. “The only real answer is to end our fossil fuel addiction by dramatically reducing our emissions, while financially supporting countries and local communities to protect their forests, rather than wrest control of them.”
- This post is a commentary. The views expressed are those of the author, not necessarily Mongabay.

Carbon counting without the guesswork: Q&A with FCL proponent Jerry Toth
- REDD+ projects aim to incentivize efforts that maintain standing forests, rather than cutting them down, by providing payments based on the carbon emissions kept out of the atmosphere.
- But REDD+, which is short for “reducing deforestation and forest degradation in developing countries,” has been widely criticized lately, in part because skeptics say that the accounting methods are open to manipulation by developers aiming to sell more credits — credits that many not represent a verifiable climate benefit.
- One alternative is the forest carbon ledger (FCL). FCL seeks to value the total amount of carbon in a forest and would provide payments based on how well that storage is maintained over time.
- Mongabay spoke with Jerry Toth, co-founder of a conservation group working to protect and restore the last remaining remnants of the Pacific Forest of Ecuador called the Third Millennium Alliance (TMA). Toth said FCL may provide a more robust alternative to REDD+ carbon accounting.

Is ocean iron fertilization back from the dead as a CO₂ removal tool?
- After a hiatus of more than 10 years, a new round of research into ocean iron fertilization is set to begin, with scientists saying the controversial geoengineering approach has the potential to remove “gigatons per year” of carbon dioxide from Earth’s atmosphere.
- The idea behind ocean iron fertilization is that dumping iron into parts of the ocean where it’s scarce could spark massive blooms of phytoplankton, which, when they die, can sink to the bottom of the sea, carrying the CO₂ absorbed during photosynthesis to be sequestered in the seabed for decades to millennia.
- So far, proof that this could work as a climate-change solution has remained elusive, while questions abound over its potential ecological impacts.
- Scientists with the Woods Hole Oceanographic Institution in Massachusetts, U.S., recently received $2 million in funding from the U.S. government that will enable computer modeling research that could pave the way for eventual in-ocean testing, effectively reviving research into ocean iron fertilization.

Forest elephants are the ‘glue’ holding Congo rainforests together
- African forest elephants play a vital role in shaping the environment and composition of the Congo Basin rainforest, including the giant carbon-sequestering trees it is noted for.
- Without them, the Congo rainforest would lose carbon stocks and biodiversity, and the composition of the forest itself would change.
- Yet the full ecological value of this charismatic species — and the ecosystem impacts if it is lost — are not fully understood, so increased funding for study and conservation is needed, experts say.
- On this final episode of the Mongabay Explores the Congo Basin podcast season, Andrew Davies, assistant professor of organismic and evolutionary biology at Harvard University, and Fiona “Boo” Maisels, a conservation scientist at the Wildlife Conservation Society, detail the unique value of forest elephants, what still remains unknown, and why urgent protection is needed.

Critical questions remain as carbon credit deal in Sabah presses forward
- Details around a secretive “nature conservation agreement” signed in 2021 between a Singaporean company and the government of Sabah, a Malaysian state on the island of Borneo, remain elusive.
- Several internationally known companies that work in climate mitigation have said they’re not affiliated with the agreement, despite implications by Jeffrey Kitingan, a deputy chief minister and the deal’s primary backer, that they are involved.
- Kitingan also revealed that Hoch Standard, the Singaporean company, is controlled by a single director through another company registered in the British Virgin Islands.
- Kitingan said the project is moving forward, leading to renewed calls from civil society, Indigenous and research organizations for the release of more details about the agreement.

Indonesia opens carbon trading market to both skepticism and hope
- Environmentalists have criticized Indonesia’s carbon trading mechanism, which had its first day of trading Sept. 26.
- The government touts the mechanism as a way to curb emissions and attract climate funding, but critics call carbon trading a false solution to climate change and a greenwashing attempt.
- Environmentalists say carbon trading could discourage companies from outright reducing emissions, enabling a “business as usual” attitude in which people and companies could buy carbon credits to continue polluting instead of changing their behaviors.
- A recent analysis by The Guardian and researchers from Corporate Accountability found that most of the top 50 emission offset projects — those that have sold the most carbon credits in the global market — were likely junk or worthless.

World owes it to Tanzania to keep Eastern Arc forests standing, study shows
- Tanzania’s Eastern Arc’s evergreen forests provide carbon sequestration that the world benefits, yet it’s local communities alone who shoulder the costs of keeping the forests standing.
- The authors of a new study recommend that international investments in conservation within the Eastern Arc worth $2 billion need to be made over the next 20 years.
- Without this, the authors say, the mountains’ forests and their extraordinary levels of biodiversity will be lost or degraded as local communities convert them to agricultural land or harvest timber from them.

‘We don’t have much time’: Q&A with climate scientist Pierre Friedlingstein
- “It’s not going in the right direction yet,” Pierre Friedlingstein tells Mongabay of the effort to meet the Paris Agreement goals; a member of the IPCC and a climate professor, he says he’s mildly optimistic about the trend in global emissions.
- Friedlingstein says he’s hoping deforestation will go down in the coming years in Brazil, but he’s not sure that Indonesia, another major global carbon sink, is ready to go in the right direction at the moment.
- He says the COVID-19 pandemic showed that climate is still “not on the top of the list” of government priorities, given that all nations sought to boost economic growth after lockdowns, despite the carbon emissions they incurred.

Revealed: Why the UN is not climate neutral
- The UN has long championed the need for urgent climate solutions. It has claimed to be at least 95% “climate neutral” every year since 2018, largely through the use of carbon credits.
- The New Humanitarian teamed up with Mongabay to investigate the UN’s claims of climate neutrality. In an investigation that took a year and spanned multiple countries, reporters obtained details about carbon credits purchased by 33 UN entities, representing more than 75% of its reported offset portfolio since 2012.
- More than a dozen of the projects that issued the UN’s carbon credits were linked to reports of environmental damage, displacement, or health concerns. Others were deemed worthless by a number of leading climate experts.

U.N. ‘stocktake’ calls for fossil fuel phaseout to minimize temperature rise
- The U.N. climate change agency published a new report Sept. 8 confirming that while there has been progress on climate change mitigation since the landmark Paris Agreement in 2015, more needs to be done to limit the global rise in temperatures at 1.5°C (2.7°F) above pre-industrial levels.
- The report is an element of the global stocktake, a Paris Agreement-prescribed inventory of progress toward climate-related goals.
- The authors of the report called for phasing out fossil fuels and ramping up renewable energy.
- The global stocktake process will conclude at the U.N. climate conference (COP28) beginning Nov. 30 in Dubai, United Arab Emirates.

El Niño hurts carbon storage in South America’s tropical forests, study says
- Climate change and El Niño are the main forces behind spiking temperatures across South America, raising questions about countries’ preparedness for extreme climate events as well as about the damage being done to the environment.
- A new study published this month in Nature revealed that, during extremely hot and dry conditions, tropical forests in South America stop acting as carbon sinks.
- But the study also found that tropical forests aren’t becoming more sensitive to drought, so conserving them can still be used to fight climate change.

Cambodia approves, then suspends, marble mine in Keo Seima REDD+ project
- The Cambodian government has suspended a planned marble mine inside a wildlife sanctuary that it had approved just months earlier.
- It’s not clear why this commercial extractive concession inside a protected area was approved in the first place, or why it’s now been suspended (but not canceled).
- The mine would have threatened an important REDD+ project in Keo Seima Wildlife Sanctuary that benefits both local communities and the area’s biodiversity.
- The REDD+ project is also a bulwark against deforestation; satellite data show it suffers far less forest loss than other parts of the wider wildlife sanctuary and surrounding areas that overlap with concessions.

What would it cost to protect the Congo Rainforest?
- The Congo Basin holds the world’s second-largest rainforest — the majority of which is in the Democratic Republic of Congo (DRC) — playing a vital role in carbon storage and ecological services that millions of people and species rely upon.
- However, the DRC is a nation with the second-highest rate of tropical deforestation behind Brazil. Meanwhile, Gabon says it has acted to protect its forests but hasn’t reaped the promised rewards.
- International commitments to protect the Congo Rainforest are historically meager compared with what experts say is actually needed, and many of these commitments go unfulfilled.
- On this episode of Mongabay Explores the Congo Basin, we speak with experts about what’s needed to overcome hurdles to financing forest protection to benefit conservation, climate and communities: Paolo Cerutti, senior scientist and DRC unit head at the Center for International Forestry Research (CIFOR-ICRAF); Chadrack Kafuti at Ghent University; Wahida Patwa Patwa-Shah, senior regional technical specialist, UNDP Climate Hub; and Lee White, minister of water, forests, the sea and environment in Gabon.

REDD+ projects falling far short of claimed carbon cuts, study finds
- New research reveals that forest carbon credits are not offsetting the vast majority of emissions that providers claim.
- A team of scientists looked at 26 REDD+ deforestation-prevention project sites on three continents, leading to questions about how the developers calculate the impact of their projects.
- The researchers found that about 94% of the credits from these projects don’t represent real reductions in carbon emissions.
- Verra, the world’s largest carbon credit certifier, said the methods the team used to arrive at that conclusion were flawed, but also added it was in the process of overhauling its own REDD+ standards.

Tropical lakes are carbon super sinks, even more than forests, study shows
- Research shows that Amazonian water bodies capture 39% more carbon per unit area than the rainforest itself.
- The research also revealed that lakes and rivers located in tropical regions with preserved forests sequester 10% of the carbon in these locations.
- The study shows the importance of preserving wetlands against climate change, the researchers say.

Macron touts forest conservation while promoting gas project on PNG visit
- During a recent visit to Papua New Guinea, French President Emmanuel Macron spent time with both fossil fuel executives and conservationists.
- Macron attended a presentation on the Managalas Conservation Area, which is supported by France as well as other European countries, and praised Indigenous peoples’ protection of the forest.
- During Macron’s visit, French firm TotalEnergies voted to undertake construction of a $10 billion liquefied natural gas project that will release an estimated 220 million metric tons of carbon dioxide.

Forest campaign group renews charge that carbon credit verification schemes are flawed
- A new assessment conducted by Rainforest Foundation UK raises fresh concerns about the validity of carbon offsetting schemes.
- The campaign group claims that all the leading carbon credit verification schemes have allowed millions of credits to enter the voluntary carbon market which do not accurately represent reductions in greenhouse gas emissions.
- RFUK is calling for a shift in emphasis to measures like global carbon levies and debt relief for poor countries, which it says would address root causes of emissions.
- Verra and several REDD+ project managers told Mongabay RFUK’s analysis is ideologically motivated, insisting that while verifying credits is not perfect, it is producing genuine, positive results.

‘What we need to protect and why’: 20-year Amazon research hints at fate of tropics
- In its bold outlines, many informed people understand that climate change is reducing tropical biodiversity and thereby degrading the functionality and ecoservices of tropical forests. But what are the specific mechanisms by which these forests are being diminished over long time frames?
- One project on the slopes of the Peruvian Amazon has tried to make exactly that type of assessment, via a 20-year ongoing research project that meticulously observes a narrow transect of rainforest stretching from the Amazon lowlands near sea level to the Andean highlands above 3,352 meters (11,000 feet).
- The international team conducting this work, the Andes Biodiversity and Ecosystem Research Group (ABERG), is painstakingly observing changes in more than 1,000 tree species, birds, frogs, snakes and more to determine not only how much climate change is affecting them, but untangling how the change process works.
- This type of in-depth research is vital to conserving tropical rainforest diversity, the carbon storage capacity it offers, and its assistance in maintaining long-persisting regional and global precipitation patterns vital to agriculture and other water needs. Mongabay contributor Justin Catanoso traveled to Peru to observe ABERG at work.

Why should funding Amazon forest sustainability be the world’s top priority? (commentary)
- In this opinion piece, Jonah Wittkamper, Mariana Senna, and Ricardo Politi argue that donors should urgently scale up support for the development of an Amazon bioeconomy based around protecting the world’s largest rainforest.
- Without such intervention, there is a risk of the Amazon rainforest ecosystem collapsing, a development that would destabilize regional rainfall, unleash massive carbon emissions, and drive large-scale species extinction.
- “Jumpstarting the region’s bioeconomy could create a permanent solution by shifting local financial incentives away from deforestation,” they write. “Philanthropy for Amazon bioeconomy development could only be necessary for several years. Catalytic funding could enable the economies of forest protection and regeneration to outcompete the economies of deforestation,” the op-ed argues.
- This article is a commentary. The views expressed are those of the authors, not necessarily Mongabay.

Drought cycles erode tropics’ ability to absorb CO₂, study finds
- A recent study finds that tropical carbon sinks have become increasingly vulnerable to water scarcity since 1960, and are consequently less able to absorb carbon dioxide.
- These findings suggest that tropical ecosystems are less resilient to climate change than previously thought.
- While the study doesn’t necessarily make projections for the future, the findings suggest that an acceleration of climate change, which is very likely to bring more drought, could further limit the ability of tropical ecosystems to absorb carbon dioxide, which, in turn, would worsen climate change.

From cardamom to carbon: Bold new Tanzanian project is regrowing a rainforest
- Farmers in eastern Tanzania are regrowing rainforest trees on part of their land.
- The farmers receive payments from the sale of carbon credits to supplement their incomes and to compensate them for loss of land and cash crops.
- So far, close to 270,000 trees have been planted on 200 hectares (494 acres) of farms located on the flanks of the Nguru Mountains.
- Nguru’s forests, home to a wealth of unique animal and plant species, are under increasing pressure from farmers who fell trees to grow crops, including valuable cardamom spice.

Forests in the furnace: Cambodians risking life and liberty to fuel garment factories
- Entire villages in parts of Cambodia have turned to illegal logging of natural forests to supply the firewood needed by garment factories churning out products for international fashion brands.
- Mongabay spoke with several people who acknowledged the illegal and dangerous nature of their work, but who said they had no other viable means of livelihood.
- The work pits them against rangers they accuse of heavy-handed tactics, including the seizure or destruction of their trucks and equipment, arrests, and extortion.
- This story was supported by the Pulitzer Center’s Rainforest Investigations Network where Gerald Flynn was a fellow. *Names have been changed to protect sources who said they feared reprisals from the authorities.

Timber harvests to meet global wood demand will bring soaring emissions: Study
- At a time when the world desperately needs to reduce its carbon emissions, global timber harvests to meet soaring demand for wood products — including paper and biomass for energy — could produce more than 10% of total global carbon emissions over coming decades, a new groundbreaking study finds.
- Global wood consumption could grow by 54% between 2010 and 2050, creating a demand for timber that would result in a “clear-cut equivalent” in area roughly the size of the continental U.S., adding 3.5 to 4.2 gigatons of carbon dioxide to the atmosphere annually for years to come.
- The study scientists warn that flawed national climate policies and faulty carbon accounting are failing to accurately forecast these potential carbon emissions resulting from the cutting of natural forests.
- The researchers point out that less natural forests need to be cut to meet the rising global demand for wood products. That demand could partially be met by increasing wood production in already existing plantation forests.

Microbes play leading role in soil carbon capture, study shows
- Soil is a significant carbon reservoir, storing more carbon than all plants, animals and the atmosphere combined, making it crucial for addressing the climate crisis.
- Microbes, such as bacteria and fungi, are the primary drivers of carbon storage in soil, surpassing other soil processes by a factor of four, according to a new study in Nature.
- The efficiency of microbial metabolism plays a vital role in determining the amount of organic carbon stored in soils worldwide, according to the research, which also calls for improved soil carbon models for effective policies and climate solutions.
- Enhancing microbial efficiency can lead to increased carbon storage in soils, but further research is needed to understand how to achieve this.

New data show 10% increase in primary tropical forest loss in 2022
- Globally, the tropics lost 4.1 million hectares (10.1 million acres) of primary forest in 2022, 10% more than in 2021.
- These losses occurred despite the pledges of 145 countries at COP26 in 2021 to increase efforts to reduce deforestation and halt it by 2030; the new data, from the University of Maryland, puts the world far off track for meeting the goal of zero deforestation.
- According to Frances Seymour of World Resources Institute, there is an urgent need to increase financing for protecting and restoring forests.

Seas of grass may be dark horse candidate to fuel the planet — or not
- Several kinds of grasses and woody shrubs, such as poplar and willow, have undergone U.S. testing for years to see if they can achieve high productivity as cellulose-based liquid biofuels for cutting greenhouse gas emissions in the global transportation sector. Some of these grasses also would have value as cover crops.
- While these experiments showed promise, the challenges for scaling up production of grass and woody shrub-derived biofuels over the next few decades remain significant. And time is short, as climate change is rapidly accelerating.
- Another roadblock to large-scale production: Millions of acres of land in the U.S. Southeast and Great Plains states would need to be earmarked for grass cultivation to make it economically and commercially viable as a biofuel.
- If many of those millions of acres required conversion of natural lands to agriculture, then deforestation and biodiversity loss due to biofuel monoculture crop expansion could be a major problem. On the plus side, grass biofuel crops likely wouldn’t directly displace food crops, unlike corn to make ethanol, or soy to make biodiesel.

Mycorrhizal fungi hold CO2 equivalent to a third of global fossil fuel emissions
- A recent study estimates that more than 13 billion metric tons of CO2 from terrestrial plants are passed on to mycorrhizal fungi each year, equivalent to about 36% of global fossil fuel emissions.
- The study highlights the overlooked role of mycorrhizal fungi in storing and transporting carbon underground through their extensive fungal networks
- Researchers analyzed nearly 200 data sets from various studies that traced carbon flow and found that plants allocate between 1% and 13% of their carbon to mycorrhizal fungi.
- Understanding the role of mycorrhizal fungi is essential for conservation and restoration efforts, as soil degradation and the disruption of soil communities pose significant threats to ecosystems and plant productivity.

U.N. climate chief calls for end to fossil fuels as talks head to Dubai
- International climate talks began in Bonn, Germany, on June 5.
- A key part of the discussion will be the global stocktake, assessing progress toward the emissions cuts pledged by nations as part of the 2015 Paris climate agreement.
- Discussions will work to provide the technical details of the stocktake, but the consensus is that the world is not on track to cut emissions by 50% by 2030, which scientists say is key to keeping the global temperature rise below 1.5°C (2.7°F) over pre-industrial levels.
- The talks are a precursor to COP28, the annual U.N. climate conference, scheduled to begin Nov. 30 in Dubai, United Arab Emirates, which is a major oil- and gas-producing nation.

Soil carbon in urban parks important in fighting climate change, study shows
- A recent study shows that urban parks and green spaces throughout the world have a similar amount of carbon stored in their soils as in natural regions close to cities, which means urban green spaces can be important to global carbon sequestration and mitigating the potential effects of climate change.
- Soil microbes in urban green spaces play a vital role in carbon storage, but that carbon is also vulnerable to loss through microbial respiration in an increasingly warmer world; researchers emphasize the need for greater understanding of the soil microbiome in urban policies and planning.
- For context, Suriname has 93% forest cover nationwide and is often referred to as the world’s “greenest” country — but the capital city, Paramaribo, lacks a structural approach to urban greenery.
- Researchers conducted a project to promote a greener and more livable Paramaribo, with the aim of mitigating the effects of climate change and raising awareness among citizens.

Protected areas store a year’s worth of CO₂ emissions, study reveals
- Researchers analyzed never-before-used satellite data to calculate how much carbon is stored in protected areas worldwide.
- The Amazon Rainforest’s protected areas accounted for the highest rate of carbon stock, according to the unprecedented study.
- The results can help policymakers and conservationists assess areas for protection to fight climate change — and not just forests.

Nearly 30% of all tree cover in Africa may be outside of forests, study says
- A team at the University of Copenhagen has generated a map of tree cover in 45 African countries down to individual tree crowns by feeding high-resolution satellite imagery into a machine-learning model.
- The analysis showed that nearly 30% of the continent’s tree cover lies outside what are traditionally considered forest areas in land-cover maps.
- For nine countries, trees outside forests account for around half their tree cover: Botswana, Burkina Faso, Eritrea, Libya, Mali, Namibia, Niger, Mauritania and Sudan.
- Such high-resolution tree-cover data could lead to more precise carbon stock assessments and better monitoring of land-use changes.

Financial downturn at Enviva could mean trouble for biomass energy
- Enviva harvests trees to manufacture millions of tons of wood pellets annually in the U.S. Southeast to supply the biomass energy demands of nations in the EU, U.K., Japan and South Korea. But a host of operational, legal and public relations problems have led to greater-than-expected revenue losses and a drastic fall in stock price.
- These concerns (some of which Mongabay has reported on in the past) raise questions as to whether Enviva can double its projected pellet production from 6 million metric tons annually today to 13 million metric tons by 2027 to meet its contract obligations. Enviva says its problems pose only short-term setbacks.
- While it isn’t possible to connect Enviva’s stock decline, or the company’s downgrading by a top credit ratings agency, with any specific cause, some analysts say that investors may be getting educated as to the financial risk they could face if the EU or other large-scale biomass users eliminate their subsidies to the industry.
- “The financial risk is there, maybe not today, but in the future, where countries may say, ‘This massive [biomass carbon accounting] loophole is making the climate crisis worse. Let’s close it.’ When that happens, Enviva and all other pellet manufacturers are out of business,” and investors would suffer, according to one industry expert.

Overlooked and underfoot, mosses play a mighty role for climate and soil
- Mosses cover a China-size area of the globe and have a significant impact on ecosystems and climate change, according to a new study.
- Researchers conducted the most comprehensive global field study of mosses to date to quantify how soil moss influences soil and ecosystem services in different environments on all seven continents.
- Soil mosses can potentially add 6.43 billion metric tons of carbon to the soil globally, an amount equivalent to the annual emissions of 2.68 billion cars.
- Moss-covered soil offers several other benefits, including cycling of essential nutrients, facilitating faster decomposition, and reducing harmful plant pathogens.

Indigenous groups voice support for REDD+, despite flaws
- A letter published May 9 and signed by a group of Indigenous-led organizations backs a mechanism for providing compensation in return for forest protection efforts known as REDD+, which is short for “reducing emissions from deforestation and forest degradation.”
- The aim of REDD+ is to provide results-based funding for economic development tied to those protection efforts, with financing coming from credits sold to companies and individuals to account for their carbon emissions.
- But critics question how carbon credits are calculated, and others have concerns about the lack of consent and participation by Indigenous and local communities most affected by REDD+ work.
- The letter argues that REDD+, in despite its shortcomings, is one of the few direct funding flows to communities for climate-related work, and they call for greater inclusion in the broader conversation about REDD+ and carbon credits and offsets.

Questions over accounting and inclusion mar Guyana’s unprecedented carbon scheme
- Guyana has put nearly all the forests in the country on the carbon market, allowing it to sign a carbon credit deal with petroleum company Hess Corporation worth $750 million, with 15% of funds going to Indigenous communities.
- However, some climate experts have questioned how ART, the independent carbon credit issuer, calculates the emissions reductions for forests that are already intact and under little threat of deforestation, saying they’re vastly overstated and bending the rules to create money.
- There are disputes between Indigenous groups about whether communities were properly and legally consulted before all their lands were put onto the carbon market.
- ART maintains that its methodology for calculating carbon reduction is conservative and important to protect intact forests, while the government insists that it properly consulted Indigenous leaders before it included their forests in the carbon scheme.

Return of the GEDI: Space-based, forest carbon-mapping laser array saved
- Since 2018, the GEDI mission has been firing lasers from the International Space Station to measure aboveground biomass on Earth.
- The information gleaned from it has been crucial for scientists to understand how deforestation contributes to worsening climate change.
- The mission was supposed to be decommissioned earlier this year, with the lasers fated to be jettisoned from the ISS and burned up in the atmosphere.
- However, NASA made a last-minute decision to extend the mission after a push from the scientists involved in it: the GEDI equipment will be put into storage for 18 months, then reinstated to resume operations for as long as the ISS continues to run.

Could biodiversity be a key to better forest carbon storage in Europe?
- A new project is reintroducing key species into Europe’s forests to help restore natural balance and boost the ability of woodlands to store carbon. But there are concerns that unless such reintroductions are made on a much wider, landscape scale, they will have little positive impact in a region so dominated by humans.
- Others argue that the best way to improve Europe’s carbon storage potential is via heavy forest management, even going so far as to clear-cut some older stands and replace them with fast-growing new forests to encourage rapid carbon uptake, and using thinnings from timber operations to burn as biomass to make energy.
- This heavy management approach has raised deep concerns within the scientific community. Many researchers say this method ignores the growing body of evidence that plantation forest monocultures are not only bad for biodiversity and store less carbon, but also increase the risk of spreading devastating diseases.
- A middle ground could see more natural management of some forests where timber is harvested, while other woodland areas are left undisturbed, with a mixture of tree species, deadwood allowed to rot where it falls, and native animals reintroduced to help restore a natural balance and healthy ecosystems.

Jatropha: The biofuel that bombed seeks a path to redemption
- Earlier this century, jatropha was hailed as a “miracle” biofuel. An unassuming shrubby tree native to Central America, it was wildly promoted as a high-yielding, drought-tolerant biofuel feedstock that could grow on degraded lands across Latin America, Africa and Asia.
- A jatropha rush ensued, with more than 900,000 hectares (2.2 million acres) planted by 2008. But the bubble burst. Low yields led to plantation failures nearly everywhere. The aftermath of the jatropha crash was tainted by accusations of land grabbing, mismanagement, and overblown carbon reduction claims.
- Today, some researchers continue pursuing the evasive promise of high-yielding jatropha. A comeback, they say, is dependent on cracking the yield problem and addressing the harmful land-use issues intertwined with its original failure.
- The sole remaining large jatropha plantation is in Ghana. The plantation owner claims high-yield domesticated varieties have been achieved and a new boom is at hand. But even if this comeback falters, the world’s experience of jatropha holds important lessons for any promising up-and-coming biofuel.

Peru national park sees deforestation spike despite carbon credit program: report
- A March report from the Associated Press revealed that the carbon credit program in Peru’s Cordillera Azul National Park has been financially profitable but ineffective as a means of conservation.
- Despite that more than 28 million credits have been sold since the program’s launch in 2008, average annual deforestation has risen significantly.
- One source of the problem is that officials inflated the benefits of the program and the threats facing the park.

Reconnecting ‘island habitat’ with wild corridors in Brazil’s Atlantic Forest
- This three-part Mongabay mini-series examines grassroots forest restoration projects carried out within isolated island ecosystems — whether those islands are surrounded by ocean as on the Big Island of Hawai‘i, or cloud forest mountaintop habitat encircled by lowlands in Costa Rica, or forest patches hemmed in by human development in Brazil.
- Reforestation of degraded island habitat is a first step toward restoring biodiversity made rare by isolation, and to mitigating climate threats. Though limited in size, island habitats can be prime candidates for reforestation because extinctions are typically much higher on isolated habitat islands than in more extensive ecosystems.
- Scientists mostly agree that the larger the forest island habitat, the greater its biodiversity, and the more resilient that forest system will be against climate change. Forests also store more carbon than degraded lands, and add moisture to soil and the atmosphere as a hedge against warming-intensified drought.
- The projects featured in this series are small in size, but if scaled up could become big forest nature-based climate solutions. In this third story, the NGO Saving Nature works to create wild corridors to reconnect fragmented patches of Brazil’s Atlantic Forest.

Do tiger-dense habitats also help save carbon stock? It’s complicated
- A new study centered on Nepal’s Chitwan National Park attempts to identify whether there’s a relationship between successful tiger conservation and habitats with high levels of carbon locked away in the vegetation.
- It found that within protected areas, high-density mixed forests had the most carbon stock sequestered in vegetation; however, tiger density was highest in riverine forests.
- This represents a trade-off that conservation planners need to tackle between tiger and carbon conservation.
- Researchers have cautioned against generalizing the findings, saying that more studies and data are needed to better understand the issue.

Mountain islands: Restoring a transitional cloud forest in Costa Rica
- This three-part Mongabay mini-series examines grassroots forest restoration projects carried out within isolated island ecosystems — whether those islands are surrounded by ocean as on the Big Island of Hawai‘i, or cloud forest mountaintop habitat encircled by lowlands in Costa Rica, or forest patches hemmed in by human development in Brazil.
- Reforestation of degraded island habitat is a first step toward restoring biodiversity made rare by isolation, and to mitigating climate threats. Though limited in size, island habitats can be prime candidates for reforestation because extinctions are typically much higher on isolated habitat islands than in more extensive ecosystems.
- Scientists mostly agree that the larger the forest island habitat, and greater its biodiversity, and the more resilient that forest system will be against climate change. Forests also store more carbon than degraded agricultural lands, and add moisture to soil and the atmosphere as a hedge against global warming-intensified drought.
- The projects featured in this series are small in size, but if scaled up could become big forest nature-based climate solutions. In this second story, two tourists vacationing in Costa Rica and stunned by the deforestation they see, buy degraded land next to Chirripó National Park and restore a transitional cloud forest.

From ukuleles to reforestation: Regrowing a tropical forest in Hawai‘i
- This three-part Mongabay mini-series examines grassroots forest restoration projects carried out within isolated island ecosystems — whether those islands are surrounded by water as on the Big Island of Hawai‘i, or cloud forest mountaintop habitat encircled by lowlands in Costa Rica, or forest patches hemmed in by human development in Brazil.
- Reforestation of degraded island habitat is a first step toward restoring biodiversity made rare by isolation, and to mitigating climate threats. Though limited in size, island habitats can be prime candidates for reforestation because extinctions are typically much higher on isolated habitat islands than in more extensive ecosystems.
- Scientists mostly agree that the larger the forest island habitat, the greater its biodiversity, and the more resilient that forest system will be against climate change. Forests also store more carbon than degraded agricultural lands, and add moisture to soils and the atmosphere as a hedge against global warming-intensified drought.
- The projects featured in this series are small in size, but if scaled up could become big forest nature-based climate solutions. In this first story, two ukulele makers strive to save Hawai‘i’s koa tree, found nowhere else in the world. In the process they restore a biodiverse tropical forest on the slopes of the Big Island’s Mauna Loa volcano.

Tropical forest regeneration offsets 26% of carbon emissions from deforestation
- A new study published in the journal Nature analyzed satellite images from three major regions of tropical forest on Earth — Amazon, Central Africa and Borneo — and showed recovering forests offset just 26% of carbon emissions from new tropical deforestation and forest degradation in the past three decades.
- Secondary forests have a good potential to absorb carbon dioxide from the atmosphere and could be an ally in addressing the climate crisis, but emissions generated from deforestation and forests lost or damaged due to human activity currently far outpace regrowth.
- The study provides information to guide debates and decisions around the recovery of secondary forests and degraded areas of the Brazilian Amazon — around 17% of the ecosystem is in various stages of degradation and another 17% is already deforested.
- Since Brazil’s new President Luiz Inácio Lula da Silva took office, projects to curb deforestation are in place, but plans to protect recovering areas remain unclear.

Carbon credits from award-winning Kenyan offset suspended by Verra
- The carbon offset certifier Verra told Mongabay it had initiated a “quality control review” of the Northern Kenya Grassland Carbon Project, which claims to store carbon by managing Indigenous livestock grazing routes.
- The project has been a darling of carbon market supporters, winning a series of awards at COP27 last year, where it was described as “exemplary” by Kenyan President William Ruto.
- A new report by the advocacy group Survival International said the offset was altering long-standing Indigenous herding practices and couldn’t accurately account for how much carbon it was removing from the atmosphere.
- Purchasers of carbon credits generated by the product include Netflix, Meta and NatWest.

IPCC warns of ‘last chance’ to limit climate change via drastic emissions cuts
- The United Nations’ Intergovernmental Panel on Climate Change (IPCC) released its sixth “synthesis” report March 20, after its approval by world leaders at a weeklong meeting in Switzerland.
- The report’s authors conclude that immediate reductions in carbon emissions are necessary to limit the rise in the global temperature to 1.5° Celsius (2.7° Fahrenheit) above pre-industrial levels.
- Scientists, activists and observers are calling for an end to fossil fuel use.

A liquid biofuels primer: Carbon-cutting hopes vs. real-world impacts
- Liquid biofuels are routinely included in national policy pathways to cut carbon emissions and transition to “net-zero.” Biofuels are particularly tasked with reducing emissions from “hard-to-decarbonize” sectors, such as aviation.
- Three generations of biofuel sources — corn, soy, palm oil, organic waste, grasses and other perennial cellulose crops, algae, and more — have been funded, researched and tested as avenues to viable low-carbon liquid fuels. But technological and upscaling challenges have repeatedly frustrated their widespread use.
- Producing biofuels can do major environmental harm, including deforestation and biodiversity loss due to needed cropland expansion, with biofuel crops sometimes displacing important food crops, say critics. In some instances, land use change for biofuels can add to carbon emissions rather than curbing them.
- Some experts suggest that the holy grail of an efficient biofuel is still obtainable, with much to be learned from past experiments. Others say we would be better off abandoning this techno fix, investing instead in electrifying the transportation grid to save energy, and rewilding former biofuel croplands to store more carbon.

Global ecosystems are at risk of losing carbon storage ability, study says
- Landscapes are showing signs of losing their ability to absorb the amount of carbon they once could, a new study revealed. That would pose serious obstacles to the fight against climate change.
- The study reviewed the productivity of carbon storage of different ecosystems between 1981 and 2018, finding that many fluctuated greatly and were at risk of turning into permanent scrubland.
- Researchers identified a concerning “spiraling” effect, in which landscapes absorb less carbon that in turn worsens climate change, which then destabilizes additional landscapes and puts them at higher risk of turning into scrubland.

Mobilizing Amazon societies to reduce forest carbon emissions and unlock the carbon market (commentary)
- Brazil could generate $10 billion or more from the global voluntary carbon market over the next four years through the sale of credits from Amazon states’ jurisdictional REDD+ programs; some states are already finalizing long-term purchase agreements.
- This funding would flow to those who are protecting the forest – Indigenous peoples and traditional communities, farmers, businesses, and government agencies – and the prospect of this funding could mobilize collective action to reduce emissions from illegal deforestation and degradation.
- Rapid progress in reducing emissions from Amazon deforestation and forest degradation – which represent half of Brazil’s nation-wide emissions – would also position Brazil to capture significant international funding for its national decarbonization process through the regulated carbon market that is under development through the UN Paris Agreement.
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Scientists map nearly 10 billion trees, stored carbon, in Africa’s drylands
- A recent study has mapped the locations of 9.9 billion trees across Africa’s drylands, a region below the Sahara Desert and north of the equator.
- The research, which combined satellite mapping, machine learning and field measurements, led to an estimate of 840 million metric tons of carbon contained in the trees.
- This figure is much lower than the amount of carbon held in Africa’s tropical rainforests.
- However, these trees provide critical biodiversity habitat and help boost agricultural productivity, and this method provides a tool to track both degradation and tree-planting efforts in the region.

Indonesia’s mangrove restoration will run out of land well short of target, study warns
- The Indonesian government’s mangrove restoration plan faces a major hurdle, according to a new study: less than a third of the target area is actually viable for restoration.
- The finding isn’t all bad news; the researchers have been invited to collaborate with the national mangrove restoration agency on “fine-tuning where these areas are, and what kind of priority they need.”
- The study found the most promising sites for restoration are on the islands of Borneo and Sumatra, which largely match the government’s own priority areas.
- Successful mangrove restoration across Indonesia could secure healthy fisheries for coastal communities and improve fisheries-based economies, thereby reducing poverty and hunger, and improving health and well-being for 74 million people.

Conservationists decry palm oil giants’ exit from HCSA forest protection group
- Palm oil giants Golden Agri-Resources (GAR) and IOI Corporation Berhad have withdrawn from the High Carbon Stock Approach (HCSA), a mechanism that helps companies reach zero deforestation targets by distinguishing forest lands that should be protected from degraded lands that can be developed.
- The companies’ exit brings the total number of firms quitting the HCSA to four, with Wilmar International and Sime Darby Plantation stepping away from the committee in 2020.
- Environmentalists say this points to a startling industry trend in which industry giants are shirking responsibility for their harmful business practices.
- Both GAR and IOI say they remain committed to using the HCSA toolkit.

Carbon market intermediaries act with little transparency, according to report
- A new report reveals that few of the brokers, resellers and cryptocurrency vendors that act as intermediaries in the voluntary carbon market reveal the commissions and markups on the credits they buy and sell.
- This lack of transparency makes it difficult, if not impossible, to accurately assess how much money from these purchases is finding its way to climate mitigation efforts.
- The report calls on intermediaries to disclose their fees and on supporting organizations to share more information about these transactions, with the goal of illuminating the true potential impact of the voluntary carbon market on climate change.

Carbon uptake in tropical forests withers in drier future: Study
- A new study incorporating satellite data on organic material, or biomass, in tropical forests with experimental data about the effects of temperature and precipitation suggests that forests may lose substantial amounts of carbon by the end of the 21st century.
- Even with low continued carbon emissions, tropical forests, especially those in the southern Amazon, could lose between 6.8 and 12% of their aboveground carbon. With higher emissions, they could lose 13.3 to 20.1% of their carbon stores.
- The results highlight the need to reduce global temperatures rapidly to maintain the healthy forests best able to sequester carbon from the atmosphere.
- The team reported their findings Feb. 6 in the journal Nature Climate Change.

Updated guide gives practical advice for buyers of tropical forest carbon credits
- An updated guide written by eight conservation and Indigenous organizations offers a detailed path forward for companies that want to compensate for their carbon emissions in addition to decarbonizing their supply chains.
- Though the carbon market faces criticism over the true value it brings to climate change mitigation, proponents say it can complement earnest efforts to decarbonize supply chains if used properly.
- The updated Tropical Forest Credit Integrity guide calls for due diligence on the part of companies to ensure the credits they purchase will result in climate gains.
- The authors of the guide also stress the importance of including Indigenous peoples and local communities in decisions about offset efforts.

Peatland restoration in temperate nations could be carbon storage bonanza
- Much maligned and undervalued over the centuries, temperate peatlands have seen a lot damage in that time — drained for agriculture, planted with trees, mined for horticulture and fuel. But in an age of escalating climate change, people are now turning to restoration.
- As potent carbon sequesters, peatlands have only recently been given new attention, with active restoration taking place in many nations around the world. This story focuses on groundbreaking temperate peatland restoration efforts in the U.S. Southeast, Scotland and Canada.
- Every temperate peatland is different, making each restoration project unique, but the goal is almost always the same: restore the natural hydrology of the peatland so it can maximize carbon storage and native biodiversity, and improve its resilience in the face of climate change and increasingly common fires in a warming world.

Forest carbon offsets are a tool, not a silver bullet (commentary)
- The Guardian recently published an article questioning the effectiveness of forest carbon offsets, immediately followed by another in Die Zeit about ‘phantom offsets.’
- These criticisms are not without precedent: carbon offsetting is often presented either as a panacea or as corporate greenwashing that distracts from the difficult task of reducing actual greenhouse gas emissions.
- But as two leaders from CIFOR-ICRAF argue in a new commentary, “It is neither one nor the other. It is a tool. No particular policy instrument stands out as a ‘silver bullet,’ but improving the coherence and complementarity of the policy mix across government levels can enhance the effectiveness of policies.”
- This post is a commentary. The views expressed are those of the authors, not necessarily of Mongabay.

Forest modeling misses the water for the carbon: Q&A with Antonio Nobre & Anastassia Makarieva
- An expanded understanding of forests’ role in moisture transport and heat regulation raises the stakes on the health of the Amazon Rainforest and the need to stop cutting trees.
- The biotic pump theory, conceived by scientists Anastassia Makarieva and the late Victor Gorshkov, suggests that forests’ impact on hydrology and cooling exceeds the role of carbon embodied in trees.
- In an interview with Mongabay, Makarieva and Brazilian scientist Antonio Nobre explain how the theory makes the case for a more urgent approach by Brazilian President Luiz Inácio Lula da Silva to protect the Amazon.

Amazonian countries must act together to reverse rainforest loss, experts say
- A group of researchers from the Science Panel for the Amazon, an initiative dedicated to the region, says reversing the destruction of the rainforest needs to be done through large-scale restoration.
- They prescribe tailored action that unlocks different benefits in areas with high deforestation rates and forest degradation, and those experiencing climate change impacts.
- So-called arcs of reforestation would need to be created across Bolivia, Colombia, Peru and Brazil, while conservation work would seek to stop further deforestation.
- According to the experts, with the exception of Brazil, Amazonian countries lack forest data for effectively running restoration actions.

Temperature extremes, plus ecological marginalization, raise species risk: Studies
- In a business-as-usual carbon emissions scenario — humanity’s current trajectory — two in five land vertebrates could be exposed to temperatures equal to, or exceeding, the hottest temperatures of the past decades across at least half of their range by 2099. If warming could be kept well below 2°C (3.6°F), that number drops to 6%, according to a new study.
- More than one in eight mammal species have already lost part of their former geographical range. In many cases, this means those species no longer have access to some (or sometimes any) of their core habitat, making it much more difficult to survive in a warming world.
- When animal populations continue to decline in an area even after it has been protected, one possible explanation may be that the conserved habitat is marginal compared to that found in the species’ historical range.
- In the light of recent pledges to protect 30% of the planet’s surface, it is important to prioritize the right areas. The focus should be on conserving core habitat — which is often highly productive and already intensively used by humans — while respecting the rights and needs of Indigenous people, many of whom have also been pushed to the margins.

Carbon markets entice, but confuse, corporations: Report
- A new report from the environmental nonprofit Conservation International and the We Mean Business Coalition, a partnership of climate NGOs, found that many corporations are interested in using carbon markets to address their emissions.
- The report, released Jan. 12, drew from the responses of 502 managers in charge of sustainability at companies in the U.S., U.K. and Europe.
- Carbon markets, which allow businesses and individuals to offset their emissions by supporting projects aimed at, say, reducing tropical deforestation, are seen by some as a necessary step to reducing carbon emissions globally.
- However, others see carbon markets and the credits they sell as a tool that allows companies to continue releasing carbon with little benefit to the overall climate.

Elephants promote jumbo trees, boosting the carbon stores in Africa’s forests
- The dietary habits of African forest elephants (Loxodonta cyclotis) promote the survival of large, high wood density trees better at storing carbon.
- New research finds that forest-dwelling elephants browse on trees with low wood density, making space for bigger, heftier carbon-rich trees.
- The elephants also act as seed dispersers for these larger trees.
- Cautioning that determining exactly what role local elephant extinctions have played in changing forest composition is tricky, the researchers argue that elephants may boost above-ground carbon storage in Central African forests by 6-9%.

Even in recovery, previously logged tropical forests are carbon sources: Study
- Logging of tropical forests may result in more carbon being released into the atmosphere than previously thought, according to new research.
- The study conducted in Malaysian Borneo demonstrates that logged tropical forests are a significant and persistent net source of carbon emissions for at least one decade after disturbance.
- The study authors say the amount of carbon being sequestered across the world’s tropical forests may be considerably lower than currently estimated and recommend a shift toward more sustainable logging practices and better accounting of carbon emissions and uptake.
- As the body of evidence expands demonstrating how human activity is impacting the capacity of forests to mitigate climate change, experts say reducing fossil fuel emissions is paramount.

The EU banned Russian wood pellet imports; South Korea took them all
- In July 2022, the European Union responded to the war in Ukraine by banning the import of Russian woody biomass used to make energy. At roughly the same time, South Korea drastically upped its Russian woody biomass imports, becoming the sole official importer of Russian wood pellets for industrial energy use.
- The EU has reportedly replaced its Russian supplies of woody biomass by importing wood pellets from the U.S. and Eastern Europe. But others say that trade data and paper trails indicate a violation of the EU ban, with laundered Russian wood pellets possibly flowing through Turkey, Kazakhstan and Kyrgyzstan to multiple EU nations.
- EU pellet imports from Turkey grew from 2,200 tons monthly last spring to 16,000 tons in September. Imports from Kazakhstan and Kyrgyzstan reportedly rose too, even though neither has a forest industry. A large body of scientific evidence shows that woody biomass adds significantly to climate change and biodiversity loss.
- Enviva, the world’s largest woody biomass producer, which operates chiefly in the Southeast U.S., may be the big winner in the Russian biomass ban. Since the war began, Enviva has upped EU shipments, and also announced a 10-year contract with an unnamed European customer to deliver 800,000 metric tons of pellets annually by 2027.

Study identifies priority forests in Oregon for max conservation benefit
- The coastal temperate rainforests of Oregon are important carbon storage facilities and provide 80% of the state’s drinking water.
- A recent study is the first to combine data on drinking water sources, biodiversity, carbon storage and forest resilience to determine which forests are the highest priority for conservation.
- Most high-priority forests are on federal lands, but only 10% are protected at the highest levels, which forbids logging and other extractive activities.
- Protecting forests is important for carbon storage and water conservation, with the loss of forest cover shown to reduce water supplies by up to 50% compared to maintaining mature forests.

Dollars and chainsaws: Can timber production help fund global reforestation?
- As global reforestation commitments grow, how will companies, governments and communities pay to restore forest ecosystems and help sequester carbon over the long-term?
- One option: Grow and sell timber on the same plots of land where reforestation work is underway, as exemplified by pioneering restoration projects in Brazil’s Atlantic Forest, where a single harvest of fast-growing eucalyptus grows up amid restored native trees. Eucalyptus sales then help pay for long-term restoration.
- Another approach is to concurrently grow tree plantations and forest restorations on separate, often adjacent, plots of land, with a large portion of the profits from timber harvests going to support the long-term management of the reforestation projects.
- But some scientists and forest advocates worry that projects or businesses that become overreliant on timber revenues to finance restoration could undermine an initiative’s environmental benefits, and lock in unintended harvesting within native ecosystems. Experts ask: Can we truly pay for new trees by cutting others down?

Zero-deforestation commitments can push agriculture to other rich biomes, study warns
- Zero-deforestation commitments (ZDCs) made by the palm oil industry and adopted by producers of other crops as well focus on preserving rainforests, while leaving other biomes unprotected.
- New research by the University of York shows that even if current ZDCs are fully met, around 167 million hectares of mostly tropical grassy and dry forest would remain open for agricultural expansion.
- Often confused with degraded areas that emerge after clearing the rainforest, those biomes are actually rich and biodiverse and also play a role in storing and capturing carbon.
- New EU legislation approved in December adds extra protection for rainforests, but could push even more agricultural production to other biomes, most of them in Africa and Latin America.

The Netherlands to stop paying subsidies to ‘untruthful’ biomass firms
- On December 5, 2022, Mongabay featured a story by journalist Justin Catanoso in which the first ever biomass industry insider came forward as a whistleblower and discredited the green sustainability claims made by Enviva — the world’s largest maker of wood pellets for energy.
- On December 15, citing that article and recent scientific evidence that Enviva contributes to deforestation in the U.S. Southeast, The Netherlands decided it will stop paying subsidies to any biomass company found to be untruthful in its wood pellet production methods. The Netherlands currently offers sizable subsidies to Enviva.
- Precisely how The Netherlands decision will impact biomass subsidies in the long run is unclear. Nor is it known how this decision may impact the EU’s Sustainable Biomass Program (SBP) certification process, which critics say is inherently weak and unreliable.
- Also in December, Australia became the first major nation to reverse its designation of forest biomass as a renewable energy source, raising questions about how parties to the UN Paris agreement can support opposing renewable energy policies, especially regarding biomass — a problem for COP28 negotiators to resolve in 2023.

Australia rejects forest biomass in first blow to wood pellet industry
- On December 15, Australia became the first major economy worldwide to reverse itself on its renewable classification for woody biomass burned to make energy. Under the nation’s new policy, wood harvested from native forests and burned to produce energy cannot be classified as a renewable energy source.
- That decision comes as the U.S., Canada, Eastern Europe, Vietnam and other forest nations continue gearing up to harvest their woodlands to make massive amounts of wood pellets, in order to supply biomass-fired power plants in the UK, EU, Japan, South Korea and elsewhere.
- In the EU, forest advocates continue with last-ditch lobbying efforts to have woody biomass stripped of its renewable energy designation, and end the ongoing practice of providing large subsidies to the biomass industry for wood pellets.
- Science has found that biomass burning releases more carbon dioxide emissions per unit of energy produced than coal. Australia’s decision, and the EU’s continued commitment to biomass, creates a conundrum for policymakers: How can major economies have different definitions of renewable energy when it comes to biomass?
