E-bikes could cut smog, energy use and congestion globally — but will they?
- The global market for e-bikes is surging. These bicycles, usually equipped with pedals and an electric motor assist, are popular with consumers and commuters and are becoming part of local business delivery systems. The trend could significantly reduce particulate pollution and smog, as well as cut carbon emissions in the transportation sector.
- But there are barriers. No international manufacturing standard yet exists for e-bikes. Also, transportation and charging infrastructure doesn’t adequately accommodate e-bikes, especially in the developing world where electric bicycles have the potential to replace super-polluting gas-powered scooters, motorcycles and pedicabs.
- Poorly made or improperly maintained e-bike batteries have developed a reputation for sometimes causing fires, exploding and even killing people, which has caused hesitation among consumers. While this safety problem is a real one, manufacturers and enthusiasts say the e-bike industry can effectively deal with it.
- Some governments are offering subsidies and tax incentives to e-bike buyers, while some companies are offering deals allowing customers to trade in gas two-wheelers for e-bikes. As sales and use grow, updated bike lane construction and safety rules setting permissible e-bike horsepower, speed and size will be required.

This year’s ranking of EV carmakers from most to least ‘clean’: Report
- A new scorecard by a coalition of labor and environmental civil society organizations ranked the top 18 automakers against 80 measures of what a clean car supply chain would look like.
- While car companies are increasingly embracing electric vehicles, a lack of tailpipe emissions is not enough for a car to be considered truly ‘clean,’ the authors say.
- From the steel, aluminum, tires, batteries and people affected along the supply chain, the mining and manufacturing of these metal-dense machines puts heavy burdens on landscapes, Indigenous peoples and workers.
- Ford and Mercedes-Benz lead the automotive world in working to clean up their supply chains, while Tesla jumped to third from last year’s ninth spot. East Asian firms fell behind as they lacked policies to address decarbonization in the production of steel and aluminum.

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: Tricky balancing act between EV scale-up and mining battery metals
- A recent study finds rapidly switching to electric vehicles could significantly cut emissions but also increase demand for critical battery metals like lithium and nickel.
- Mining metals like lithium has major environmental impacts including deforestation, high water use, and toxic waste.
- Electrifying heavy-duty vehicles requires substantially more critical metals than other EVs and could account for 62% of critical metal demand in coming decades despite making up just 4-11% of vehicles.
- The researchers recommend policies to support recycling, circular economies, alternative battery chemistries, and coordinated action to balance environmental and material needs.

EVs offer climate hope, but total auto supply chain revamp is vital
- Internal combustion engine vehicles (ICE) and electric vehicles (EV) both have supply chains that generate significant environmental impacts. Experts argue that circular economy principles — based on reducing, reusing and recycling materials — are key to increasing EV sustainability. But the auto industry has far to go to get there.
- Circularity is deemed particularly important for EVs, which are tipped as a vital climate solution and as the future of light transport across the globe. But their introduction globally is dependent on soaring material resourcing and production, all coming with “embedded emissions,” pollution and other impacts.
- At present, circularity is low in the auto industry, but experts see great potential, particularly for EV batteries. They argue for changes all along the supply chain to reduce material use and encourage advanced recycling.
- Others emphasize a holistic approach to land transport that reduces demand for automobiles in favor of public transportation. Circular economy solutions need to be achieved quickly in the transport sector if emissions are to be cut enough to help curb climate change and reduce pollution and other environmental ills.

Aviation’s climate conundrum: More than sustainable fuels needed
- Critics and researchers caution that pinning aviation’s carbon-cutting hopes on sustainable aviation fuels (SAFs) is problematic. These fuels, derived from liquid biofuels, along with synthetic fuel options such as green hydrogen, have been produced in only miniscule amounts at high cost compared to what’s needed.
- Scaling SAFs up to cover all of the aviation industry’s carbon-reduction goals while avoiding environmental harm will be a mammoth technological and economic challenge, and may not be achievable in the time available as climate change rapidly escalates, say experts.
- Other solutions will almost assuredly be required: Hydrogen-powered or electric planes may be on the horizon for private or short-haul flights. But reducing emissions from commercial, long-haul flights remains a far greater challenge.
- A mixture of technological solutions, increased efficiencies in airplane design, better airport management, and new innovative policies, including controversial ideas to curb customer demand for air travel, are likely needed to cap and significantly bring down commercial aviation’s emissions fast.

Forests in the furnace: Cambodia’s garment sector is fueled by illegal logging
- An investigation has found factories in Cambodia’s garment sector are fueling their boilers with wood logged illegally from protected areas.
- A Mongabay team traced the network all the way from the impoverished villagers risking their lives to find increasingly scarce trees, to the traders and middlemen contending with slim margins, up to the factories with massive lots for timber supplies.
- The garment industry association denies that any of its members uses forest wood, but the informal and opaque nature of the supply chain means it’s virtually impossible to guarantee this.
- 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.

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.

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.

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.

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.

Companies eye ‘carbon insetting’ as winning climate solution, but critics are wary
- A tool that wields the techniques of carbon offsets is surging among companies claiming that it reduces their carbon footprints. The tool, known by some as “insetting,” had simmered for more than a decade on the fringes of climate action among brands that rely on agriculture, but is now expanding to other sectors.
- Insetting is defined as company projects to reduce or remove emissions within their own internal supply chains. Proponents say it is valuable for agriculture-based firms struggling to address indirect emissions from land that has already been deforested. Like offsets, insetting can bring social and economic benefits to communities.
- Some oppose the tool outright, saying it is subject to the same problems as offsets (including lack of permanence and enforceable standards), but can also be worse as it can lead to double-counting climate benefits and can have weaker oversight.
- Having now become popular with major corporations such as Nestlé and PepsiCo, insetting as a climate tool is poised to see increased scrutiny as companies and researchers figure out its place in corporate action and reckon with the urgency to reduce emissions from agriculture.

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.

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.

To cut emissions from cattle ranching, beef up the soil, study says
- A pilot project funded by the World Bank in Colombia’s Vichada municipality found that land management techniques paired with the implementation of a tropical grass species increased carbon storage in the soil by more than 15%, while also avoiding the need for cyclical burning of the savanna.
- Improving the productivity of inefficient ranching practices can boost profits for ranchers while combating growing food insecurity in Colombia, say the authors of a recent study documenting the pilot project.
- The study comes amid relative silence at the COP27 climate summit about the role of livestock in climate change: A quarter of all global emissions come from the livestock industry, yet serious measures to reduce or improve these systems are not being discussed enough, experts say.
- Scientists not involved with the pilot project have welcomed the findings but note that biodiversity indicators also need to be measured to compare the improved pastures to natural savanna.

Sri Lanka university aims to be the country’s first to go carbon neutral
- The University of Sri Jayewardenepura (USJ) in Sri Lanka has assessed its carbon footprint under ISO standards and has now become the country’s first university to be carbon audited.
- USJ recently assessed its carbon footprint under the ISO 14064-1 standard, a process that proved to be more difficult than calculating the footprint of an industrial establishment such as a factory, which has more easily quantifiable carbon emissions than a university.
- The university intends to reach carbon-neutral status mainly through energy efficiency projects and reforestation of three forest patches managed by the university in order to offset its carbon emissions.

LED lights could contribute to massive carbon reductions
- The world has been shifting away from wasteful incandescent and harmful fluorescent lights and increasingly adopting light-emitting diode (LED) technology, which promises to reduce carbon emissions.
- Yet despite widespread adoption of the technology, virtually no LEDs are currently recycled or reused for their parts.
- To counter this problem, researchers are exploring ways in which LEDs can be designed for reuse and repair, as well as improving the efficiency of recycling.

Carbon offsets: A key tool for climate action, or a license to emit?
- The carbon offset market has existed for 25 years, and experts say there are still fundamental problems in its structure. Some question the underlying concepts, and refuse to consider it a tool for climate action.
- Part of the issue is that transparency is low. Buyers and sellers of carbon offsets often never meet and are separated by numerous intermediaries with their own profit incentives: registries, verifiers, and brokers. It’s not clear who buys offsets or which emissions are offset.
- Most experts say the offset market is not meant to contribute meaningful change to emissions, but rather to be an extra tool to channel funds toward sustainable development when companies are failing to transition from fossil fuels.

Playing dangerously: The environmental impact of video gaming consoles
- Like other consumer electronics, game consoles require complex supply chains that rely on the mining of metals and rare-earth elements, the production of new plastics, and highly specialized manufacturing processes — linking the industry to oversized carbon emissions.
- The latest generation of consoles use around 200 watts of electricity, placing them at the upper end of household appliances. U.S. gaming consoles churn through roughly 34 terawatt-hours of electricity per year, associated with an estimated 24 million metric tons of carbon emissions.
- While the newer devices have built-in energy efficiencies, their added features and performance upgrades often eat up those savings. The rapid replacement of one generation with the next has also led to a path of designed obsolescence, which has resulted in complex waste and disposal issues.
- Awareness of gaming’s oversized environmental impact has grown, and major manufacturers have promised to reduce the environmental footprint of their consoles over the next two decades, but consumer demand for longer console life spans and greater repairability will be key.

Is having fewer kids the answer to the climate question? | Problem Solved
- The human population is expected to reach 8 billion literally any day now, and nearly 10 billion people some time this century.
- With the planet also swiftly approaching 1.5° Celsius (2.7° Fahrenheit) of warming above pre-industrial levels, activists and scientists are urging any solution to keep temperatures from shooting higher into the danger zone.
- Research suggests that the single biggest thing anyone can do to reduce their impact on the environment, and the climate, is to choose to have one less child. But that simple solution is complicated by thorny economic, ethical, social and political issues.
- On this episode of Problem Solved, we unpack the research, and examine this sensitive and controversial question: Is choosing collectively to have fewer children really a viable solution to our climate change and/or resource overuse crises?

Biomass cofiring loopholes put coal on open-ended life support in Asia
- Over the past 10 years, some of Asia’s coal-dependent, high-emitting nations have turned to biomass cofiring (burning coal and biomass together to make electricity) to reduce CO2 emissions on paper and reach energy targets. But biomass still generates high levels of CO2 at the smokestack and adds to dangerous global warming.
- In South Korea, renewable energy credits given for biomass cofiring flooded the market and made other renewables like wind and solar less profitable. Although subsides for imported biomass for cofiring have decreased in recent years, increased domestic biomass production is likely to continue fueling cofiring projects.
- In Japan, renewable energy subsidies initially prompted the construction of new cofired power plants. Currently, biomass cofiring is used to make coal plants seem less polluting in the near term as utilities prepare to cofire and eventually convert the nation’s coal fleet to ammonia, another “carbon-neutral” fuel.
- In Indonesia, the government and state utility, encouraged by Japanese industry actors, plan to implement cofiring at 52 coal plants across the country by 2025. The initiative will require “nothing less than the creation of a large-scale biomass [production] industry,” according to experts.

Building Indonesia’s ‘green’ new capital could see coal use surge (analysis)
- Indonesia is planning to construct a new capital city, known as Nusantara, in the Bornean province of East Kalimantan.
- Authorities promote Nusantara as a “green city,” but discussions of the city’s carbon footprint overlook key factors, notably the use of coal to manufacture the building materials required to construct a completely new city.
- With the new city being built in the country’s coal-mining heartland, coal is the most likely energy source for such manufacturing, putting Indonesia’s emissions reduction targets at risk, as well as casting doubt on the green commitments of funders like Japan and China.

As biomass burning surges in Japan and South Korea, where will Asia get its wood?
- In 2021, Japan and South Korea imported a combined 6 million metric tons of wood pellets for what proponents claim is carbon-neutral energy.
- Large subsidies for biomass have led Japan to import massive amounts of wood pellets from Vietnam and Canada; two pellet giants, Drax and Enviva, are now eyeing Japan for growth, even as the country may be cooling to the industry.
- South Korea imports most of its pellets from Vietnamese acacia plantations, which environmentalists fear may eventually pressure natural forests; South Korea wants to grow its native production sixfold, including logging areas with high conservation value.
- Vietnam may soon follow Japan and South Korea’s path as it phases out coal, and experts fear all this could add massive pressure on Southeast Asian forests, which are already among the most endangered in the world.

Training on pasture recovery is a win-win for Brazil’s cattle ranchers and forests
- A recent study found that providing Brazilian cattle ranchers with customized training in sustainable pasture restoration could bring long-term economic and environmental benefits.
- Trained ranchers saw an increase in cattle productivity and revenue, and a reduction in carbon dioxide emissions over a period of two years.
- Researchers say that recovering degraded pastures could help stop deforestation for agriculture by allowing farmers to increase cattle numbers without needing more land.
- Despite government-led programs that promote sustainable agriculture, experts say pasture recovery is not yet being fully prioritized.

Missing the emissions for the trees: Biomass burning booms in East Asia
- Over the past decade, Japan and South Korea have increasingly turned to burning wood pellets for energy, leaning on a U.N. loophole that dubs biomass burning as carbon neutral.
- While Japan recently instituted a new rule requiring life cycle greenhouse gas emissions accounting, this doesn’t apply to its existing 34 biomass energy plants; Japanese officials say biomass will play an expanding role in achieving Japan’s goal of reducing greenhouse gas emissions by 46% by 2030.
- South Korea included biomass burning in its renewable energy portfolio standard, leading to 17 biomass energy plants currently operating, and at least four more on the way.
- Experts say these booms in Asia — the first major expansion of biomass burning outside Europe — could lead to a large undercounting of actual carbon emissions and worsening climate change, while putting pressure on already-beleaguered forests.

Climate pledges could limit warming to 2C. What’s needed is action, study says
- A new study has suggested that global temperatures can be limited to 2°C (3.6°F) above pre-industrial levels if countries fully meet all of their climate pledges on time.
- However, the researchers say that rapid action is needed within the decade to meet the targets necessary to fulfill this goal.
- This analysis comes shortly after the publication of the United Nations’ Intergovernmental Panel on Climate Change’s (IPCC) latest report, which says that greenhouse gas emissions must peak by 2025 and nations need to reach net-zero emissions by the 2050s.

More Zoom, less climate gloom as conferences move online, study finds
- A new study found that moving conferences online can reduce the carbon footprint by 94% and energy use by 90%.
- It also found that hybrid events, in which some participants attend in person while others attend online, could reduce carbon footprint and energy by two-thirds by taking measures like carefully choosing a location and only serving plant-based foods.
- While some professionals are dissatisfied with online conferences, mainly due to poor networking opportunities, others have expressed satisfaction with these formats’ accessibility, and the lowering of carbon footprints and costs.

Mongabay Explains: Do carbon offset markets really work?
- Companies with high carbon footprints around the world have made pledges to reduce carbon emissions, aiming to become carbon neutral and even carbon negative.
- The solution they are turning to is ‘carbon offset trading,’ which allows them to invest in environmental projects as a counterweight to their carbon-emitting industrial activities.
- But carbon offset markets’ increasing popularity has met with controversy about corporations absolving themselves without contributing to an overall reduction in emissions, and questions about how they can ensure the schemes’ success without physically visiting the projects.
- In this video, Mongabay explains if carbon offset markets really do work.

Fighting climate change is a dirty job, but soils can do it | Problem Solved
- The Earth’s soil stores nearly three times as much carbon as all plants, animals and the atmosphere combined, researchers say.
- However, unchecked deforestation, modern industrialized agriculture, the failure to recognize Indigenous land rights, and the continued extraction and burning of fossil fuels are all putting our crucial carbon sinks in the tropics and subarctic permafrost at risk of releasing much of that carbon.
- Experts agree that protecting soil is key to mitigating climate change, and to avoid breaching delicate planetary boundaries that are necessary to sustain human life on the planet.
- Doing so means fundamental shifts in how we grow our food, conserve and restore forests, and swiftly reduce our use of fossil fuels.

As fossil fuel use surges, will COP26 protect forests to slow climate change?
- Despite the world’s commitment in Paris in 2015 to hold back the tide of global warming, carbon emissions continue rising, while impacts are rapidly escalating as heat waves, drought and extreme storms stalk the world’s poorest and richest nations — bringing intensified human misery and massive economic impacts.
- Once viewed optimistically, nature-based climate solutions enshrined in Article 5 of the Paris Agreement (calling for protections of carbon-storing forests, peat bogs, wetlands, savannas and other ecosystems) is now threatened by politics as usual, and by the unabated expansion of agribusiness and extraction industries.
- As world leaders gather in Scotland for the COP26 climate summit, scientists and advocates are urging negotiators to at last finalize comprehensive effective rules for Article 5, which will help assure “action to conserve and enhance, as appropriate, sinks and reservoirs of greenhouse gases … including forests.”
- Over the first two weeks in November at COP26, the vision and rules set at Paris are to be settled on and fully implemented; John Kerry, co-architect of the Paris accord and President Joe Biden’s climate envoy, calls this vital COP the world’s “last best chance” to finally move beyond mostly empty political promises into climate action.

Plastics set to overtake coal plants on U.S. carbon emissions, new study shows
- A new report released by Beyond Plastics suggests that plastics will release more greenhouse gas emissions than coal plants in the U.S. by 2030.
- It argues that plastics production in the U.S. is currently responsible for 232 million metric tons of greenhouse gases every year, the equivalent of 116.5 gigawatts of coal plants. These numbers are likely to increase as production expands.
- However, experts say that policymakers do not currently account for the impact plastics currently have on climate change and that the issue is flying under the radar.

Forest finance expected to advance under new TREES standard and LEAF Coalition
- The latest edition of the TREES standard for forest carbon crediting attempts to bring together the best of what the private sector can do and the best of what governments can do to protect forests. It is explicit about how projects can be integrated into jurisdiction-level accounting.
- While effectively directing capital to forest communities on the ground, REDD+ projects have been dogged by methodological problems and what in some cases appear to be spurious claims of climate impact.
- The designers of TREES say that with its jurisdictional scale and transparent carbon accounting guidelines, it will better address the main credibility risks so far associated with REDD+ carbon credits.
- Almost 15 years after the original REDD framework, many regard TREES and the LEAF Coalition announced in April 2021 as the first real attempt at credible REDD+ implementation at scale.

Even as the government bets big on carbon, REDD+ flounders in Madagascar
- The Malagasy government’s decision to ban the sale of carbon credits as it reworks its REDD+ strategy has left all existing REDD+ projects in a limbo.
- The island nation only has a handful of projects, all helmed by foreign NGOs, which take advantage of the U.N.’s reducing emissions from deforestation and forest degradation (REDD+) program to raise money by selling carbon credits.
- Madagascar’s environment minister singled out an initiative by U.K.-based nonprofit Blue Ventures, criticizing it for striking a deal promising too little: $27,000 per year for 10 villages. The NGO disputes this appraisal.
- The government’s move to nationalize carbon ownership comes against the backdrop of familiar concerns about REDD+, in particular: how much do communities benefit from keeping forests standing?

Soil and its promise as a climate solution: A primer
- We know that soil feeds plants, but do we know how it got there in the first place? Soil forms via the interaction of five factors: parent material, climate, living beings, a land’s topography, and a “cooking” time that occurs on a geologic scale. Variations in these 5 factors make the world’s soils unique and extremely diverse.
- Soil acts as a carbon sink in the global carbon cycle because it locks away decomposed organic matter. But deforestation, various agricultural practices, and a changing climate are releasing it back into the atmosphere and oceans as carbon dioxide, resulting in an imbalance in global carbon budgets
- Tropical soils and permafrost hold the most soil carbon out of other biomes, making them conservation and research priorities in soil-centered climate solutions.
- Reforestation of previously forested lands is a viable solution to return carbon belowground, but it is not a fix-all. Changing industrial agricultural practices and giving high-carbon storage areas conservation status are key steps toward harnessing the soil’s carbon storage power.

The key to averting environmental catastrophe is right beneath our feet
- Billions of years ago, the first soils served as a cradle for terrestrial life. Today, the land beneath our feet underpins a multitrillion-dollar, global agricultural industry and provides food for nearly 8 billion humans, along with countless wild and domestic species. But soils are in global crisis.
- We are now living in the “danger zone” for four of the nine planetary boundaries: climate change, biodiversity, land-use change, and biogeochemical flows. All four are intimately linked to soil health. Soils hold 80% of all the carbon stored on land.
- Deteriorating soil health is already gravely impacting lives and livelihoods. Land degradation due to human activities costs around 10% of global gross product. When combined with climate change effects, soil degradation could reduce crop yields by 10% globally by 2050.
- There is an inevitable delay between recognizing global problems and enacting solutions, and seeing the resulting boost to ecosystem services. That’s why we must act now if we are to leverage soil ecosystems in the fight against disastrous global environmental change.

Bold sustainability commitments: An interview with Microsoft’s Lucas Joppa
- One of the boldest climate commitments in 2020 came from the tech giant Microsoft, which in January pledged to be carbon negative by 2030 and to address its legacy emissions–all the carbon the company has emitted since its founding in 1975–by 2050.
- Microsoft has also committed to replenish more water than it consumes and produce zero net waste by 2030, while protecting more land than it uses by 2025. Further, the company said it would lend its computing power toward efforts to combat biodiversity loss and use its voice to advocate for public policies that “measure and manage ecosystems.”
- Heading up these ambitious sustainability initiatives is Microsoft’s chief environmental officer Lucas Joppa, a Ph.D. ecologist who also conceived of Microsoft’s AI for Earth platform.
- Joppa spoke with Mongabay Founder Rhett A. Butler in a December 2020 interview.

Brazil green recovery plan could boost economy, add jobs, cut emissions: Report
- If Brazil shifts to a low carbon economy, carbon emissions would be cut by a third while also creating jobs, benefiting economic growth and infrastructure, according to a recent report by the World Resources Institute.
- Brazil’s post-COVID-19 economic recovery plan could provide an opportunity to implement long-term solutions across multiple sectors that could reduce carbon emissions and Amazon deforestation.
- Study authors hope that the economic benefits of the plan will push the current Jair Bolsonaro administration to adopt a green agenda, even if conservation is not a priority.
- “Climate denial is at a peak, but cost-benefit will be the leading decision-maker, whether or not it benefits the environment.… Due to post-COVID-19 economic recovery plans, we have a window of opportunity that will close in a year and a half or less.” — World Resources Institute Climate Policy Director Carolina Genin.

Energy-guzzling McMansions make the American dream a climate nightmare
- A new study finds that wealthy Americans living in spacious houses in upscale neighborhoods are responsible for 25% more greenhouse gas emissions on average than those living in smaller homes in poorer areas.
- The U.S. has one of the highest per capita emissions of any country, and residential properties account for almost a quarter of the country’s total carbon footprint, larger than the total emissions for Germany.
- By looking at energy consumption patterns of nearly 100 million households from 2015, the researchers found out that Maine, Vermont and Wisconsin were the largest consumers of energy that year.
- Only if homes are smaller and more tightly packed together, the power grid is cleaner, and energy consumption is reduced, would the U.S. be able to achieve emissions reductions targets for homes laid down in the Paris Agreement, the study says.

China and EU appetite for soy drives Brazilian deforestation, climate change: Study
- A recent study highlights how demand for Brazilian soy by Europe and China is stoking deforestation, thereby increasing carbon emissions, especially in Brazil’s Cerrado savanna biome, followed by the Amazon rainforest.
- The extent to which Brazilian soy production and trade contribute to climate change depends largely on the location where soybeans are grown. Soy exported from some municipalities in Brazil’s Cerrado, for example, contributes 200 times more total greenhouse gas emissions than soy coming from other parts of the country.
- China was the world’s largest importer of Brazilian soy from 2010 to 2015 and responsible for 51% of associated carbon dioxide emissions, with the European Union responsible for about 30%. However, EU soy imports (sourced from the northern Cerrado) were linked to more recent deforestation than China’s imports.
- The study is the first to offer an estimate of carbon emissions across Brazil’s entire soy sector. The data obtained by analyzing 90,000 supply chain streams could help policymakers curb emissions by designing low-carbon supply chains, with more effective forest conservation, and making improvements in transport infrastructure.

Trendy, cheap, and dirty: Fashion is a top global polluter
- The fashion industry is a major global polluter and source of greenhouse gas emissions, driven in large part by the “fast fashion” business model that treats cheap clothing as a perishable good that can be disposed of after brief use.
- Globalization has aided this trillion-dollar trend, allowing brands to outsource different links of their supply chains to countries with little to no environmental and labor protections in order to keep costs down.
- That has led to widespread pollution and labor rights abuses, particularly against women workers, epitomized by the collapse of the Rana Plaza building in Bangladesh on April 24, 2013, in which more than 1,134 workers were killed. This week, to marks the seventh anniversary of the tragedy and advocates for a return to a more sustainable “slow fashion” model have launched the “Fashion Revolution Week.”
- A newly published review paper in Nature Reviews Earth & Environment highlights the environmental consequences of fast fashion, fashion’s complex international supply chain, and proposes solutions to bring us into a cleaner fashion future.

As investment giant BlackRock pulls back from coal, NGOs urge the same for biomass energy
- BlackRock, the world’s largest asset management corporation, announced in January that it would be reducing investments in coal due to the fuel’s role in climate change.
- Environmental organizations laud the move, but say it’s not enough. In March, a coalition of 32 organizations from 17 countries delivered a letter stating burning biomass was more polluting than burning coal and asking BlackRock to divest its 5% stake in UK-based Drax, operator of the world’s largest wood-burning power plant.
- Biomass energy is commonly produced by burning wood pellets. Critics of the wood pellet industry say it produces tons of carbon emissions while leveling old-growth and managed forests in the U.S. Southeast and Eastern Europe needed for carbon sequestration, biodiversity protection and resiliency from increasingly intense storms and flooding.
- However, biomass was designated a renewable energy source in the 1997 Kyoto Protocol on par with zero-emissions wind and solar energy. Because of this, countries that burn wood pellets do not have to count the emissions it produces. This gives an on-paper-only impression of carbon emissions reductions, thus putting a dent in the global effort to meet Paris Agreement emission-reduction goals to keep warming to 1.5 degree C this century over a 1900 baseline. Global temperatures have already risen 1 degree C over the past 120 years.

Arctic permafrost moving toward crisis, abrupt thaw a growing risk: Studies
- An estimated 1,400 gigatons of carbon is currently embedded in the world’s permafrost, mostly in the Arctic and sub-Arctic. By comparison, the atmosphere presently contains just 850 gigatons. Should a major proportion of existing permafrost thaw, the Earth could experience dramatic and very dangerous warming.
- Scientists are already seeing an escalation of permafrost thawing. Worse may lie ahead: one study found that for every 1 degree C rise in Earth’s average temperature, permafrost may release the equivalent of 4-6 years-worth of fossil fuel emissions — likely requiring adjustments in Paris Accord national carbon reduction targets.
- Knowing the rate and amount of gradual permafrost thaw will aid researchers in understanding just how quickly we need to cut human-caused emissions. But researchers are also deeply concerned about the possibility of abrupt permafrost thaws, over large areas.
- Abrupt thaws could shock the landscape into releasing far more carbon than if thawed slowly. Abrupt releases may trigger a feedback loop whereby permafrost emissions would warm the atmosphere, leading to more thaw and release. By not accounting for abrupt thaws, we may be underestimating permafrost carbon release impacts by 50 percent.

Success of Microsoft’s ‘moonshot’ climate pledge hinges on forest conservation
- One mechanism by which the 2015 Paris Climate Agreement incentivizes greenhouse gas reductions is via carbon offsets, payments that compensate nations, states and private landowners who agree to keep forests intact in order to preserve carbon storage capacity and biodiversity.
- But problems exist with forest carbon offset initiatives: corrupt landowners, lack of carbon accounting transparency, and low carbon pricing have caused wariness among investors, and failed to spur forest preservation.
- Now, in a landmark move, Microsoft has pledged to go “carbon negative” by 2030, and erase all the company’s greenhouse gas emissions back to its founding in 1975 by 2050. A big part of achieving that goal will come via the carbon storage provided by verified global forest conservation and reforestation projects around the globe.
- To achieve its goal, Microsoft has teamed with Pachama, a Silicon Valley startup, that seeks to accurately track forest carbon stocks in projects in the Brazilian and Peruvian Amazon, the U.S. and elsewhere using groundbreaking advanced remote-sensing technology including LiDAR, artificial intelligence and satellite imaging.

Hopes dim as COP25 delegates dicker over Article 6 and world burns: critics
- Even as half a million protesters demonstrate outside, UN climate summit negotiators inside Madrid’s COP25 seem blind to the urgency of the climate crisis. In fact, instead of making effective progress, the rules they’re shaping to carry out the Paris Agreement’s Article 6 could worsen carbon emissions, not staunch them.
- For example, Article 6 doesn’t include rules to protect native forests. Instead it could promote turning forests into monoculture tree plantations — providing minimal carbon sequestration and no ecosystem services, while devastating biodiversity. Some critics think the policy may have been shaped by logging interests.
- The so-called biomass carbon accounting loophole is also not up for discussion. Its continuance will allow the burning of biomass wood pellets at power plants, energy production classified by the UN as carbon neutral. However, establised science has found that industrial biomass burning will add significantly to carbon emissions.
- According to activists at COP25, delegates are working to hide emissions and allow UN carbon accounting loopholes. One key aspect of Article 6 found in the original Paris Agreement which guaranteed “the protection of human rights” was deleted from a revised draft Saturday night, as was verbiage assuring civil society and indigenous consultations.

COP25 may put climate at greater risk by failing to address forests
- COP25, originally slated for Brazil, then Chile, but starting today in Madrid comes as global temperatures, sea level rise, wildfires, coral bleaching, extreme drought and storms break new planetary records.
- But delegates have set a relatively low bar for the summit, with COP25’s primary goal to determine rules under Article 6 of the 2015 Paris Climate Agreement for creating carbon markets among nations, cities and corporations as a means of incentivizing emission-reduction strategies.
- Policy experts warn that global forest conservation is not yet being actively incentivized as part of carbon market discussions, a possible lapse apparently backed by Brazil and the government of Jair Bolsonaro which has declared its plan to develop the Amazon basin — the world’s largest remaining rainforest and vital to sequestering carbon to curb climate change.
- COP25 also seems unlikely to address the UN biomass carbon accounting loophole, which allows nations to convert obsolete coal plants to burn wood pellets to produce energy, with the carbon emitted counted as “zero emissions” equivalent to solar and wind. Scientists warn that biomass burning, far from being carbon neutral, is actually worse than burning coal.

UN and policymakers, wake up! Burning trees for energy is not carbon neutral (commentary)
- On September 23, the signatories of the Paris Climate Agreement will gather at the United Nations for a Climate Action Summit to step up their carbon reduction pledges in order to prevent catastrophic climate change, while also kicking off Climate Week events in New York City.
- However, the policymakers, financiers, and big green groups organizing these events will almost certainly turn a blind eye toward renewable energy policies that subsidize forest wood burned for energy as if it is a zero emissions technology like wind or solar.
- Scientists have repeatedly warned that burning forests is not in fact carbon neutral, and that doing so puts the world at risk of overshooting the Paris Agreement’s 1.5°C target.
- But that message has fallen on deaf ears, as lucrative renewable energy subsidies have driven exponential growth in use of forest wood as fuel. The world’s nations must stop subsidizing burning forest biomass now to protect forests, the climate, and our future. This post is a commentary. The views expressed are those of the author.

Carbon to burn: UK net-zero emissions pledge undermined by biomass energy
- The United Kingdom and the European Union are setting goals to achieve net-zero carbon emissions by 2050. But that declaration is deeply flawed, analysts say, due to a long-standing United Nations carbon accounting loophole that turns a blind eye toward the conversion of coal burning power plants to burning wood pellets.
- While the cutting of trees to convert them to wood pellets to produce energy is ultimately carbon neutral — if an equal number of new trees are planted — the regrowth process requires 50 to 100 years. That means wood pellets burned today, and in coming decades, will be adding a massive carbon load to the atmosphere.
- That carbon will add significantly to global warming — bringing more sea level rise, extreme weather, and perhaps, climate catastrophe — even as official carbon counting by the UN provides a false sense of security that we are effectively reducing emissions to curb climate change.
- Unless the biomass loophole is dealt with, the risk is very real that the world could easily overshoot its Paris Agreement targets, and see temperatures rise well above the 1.5 degrees Celsius safe limit. At present, there is no official move to address the biomass loophole.

EU sued to stop burning trees for energy; it’s not carbon neutral: plaintiffs
- Plaintiffs in five European nations and the U.S. filed suit Monday, 4 March, in the European General Court in Luxembourg against the European Union. At issue is the EU’s rapid conversion of coal-burning powerplants to burn wood pellets and chips, a process known as bioenergy. Activists see the EUs bioenergy policies as reckless and endangering the climate.
- Bioenergy was classified as carbon neutral under the Kyoto Protocol, meaning that nations don’t need to count wood burning for energy among their Paris Agreement carbon emissions. However, studies over the last 20 years have found that bioenergy, while technically carbon neutral, is not neutral within the urgent timeframe in which the world must cut emissions.
- In essence, it takes many decades for new tree growth to re-absorb the amount of carbon released from burning mature trees in a single day. But the UN Intergovernmental Panel on Climate change last October said that the world has just 12 years – not decades – to drastically cut emissions or face likely disastrous temperature rise and climate impacts.
- The activists filing suit face a difficult fight. Only EU member states and EU institutions are generally given standing to challenge legislative acts. To gain standing, they will have to prove that they are being impacted by the EU’s bioenergy policies. The activists say that ending bioenergy coal plant conversions is vital if the world is to avoid catastrophic climate change.

COP24: Summit a step forward, but fails to address climate urgency
- COP24 ran into overtime over the weekend as delegates rushed to approve the Paris rulebook to set up a detailed mechanism for accomplishing and gauging the carbon reduction pledges made by the world’s nations in Paris at the end of 2015.
- But considering the urgency of action needed – with just 12 years left to act decisively to significantly cut emissions, according to an October IPCC science report – the COP24 summit proved to be less successful than many participants had hoped.
- On the negative side: the U.S., Russia and Saudi Arabia tried to undermine the gravity of the IPCC science report. Brazil successfully scuttled plans for an international carbon market. And COP24 failed to address the bioenergy carbon counting loophole, which incentivizes the harvesting and burning of trees to make energy by calling the process carbon neutral.
- On the positive side, “1,000 tiny steps” were made, including an improved transparency framework for reporting emissions; regular assessments called Global Stocktake to gauge emissions-reduction effectiveness at national levels starting in 2023; and an agreement to set new finance goals in 2020 to help vulnerable nations adapt to a warming world.

COP24: Will they stay or will they go? Brazil’s threat to leave Paris
- In October, Brazil elected far-right candidate Jair Bolsonaro to the presidency. During the campaign, he threatened to withdraw from the Paris Climate Agreement, implement extreme environmental deregulation policies, and introduce mining into Amazon indigenous reserves, while also using incendiary language which may be inciting violence in remote rural areas.
- Just days before his election, Bolsonaro contradicted his past utterances, saying he won’t withdraw from the Paris accord. At COP24, the Brazilian delegation has fielded questions from concerned attendees, but it appears that no one there knows with certainty what the volatile leader will do once in office. He begins his presidency on the first of the year.
- Even if Bolsonaro doesn’t pull out of Paris, his plans to develop the Amazon, removing most regulatory impediments to mining and agribusiness, could have huge ramifications for the global climate. The Amazon, the world’s largest rainforest, stores massive amounts of carbon. Deforestation rates are already going up there, and likely to grow under Bolsonaro.
- Some in Brazil hope that environmental and economic realities will prevent Bolsonaro from fully implementing his plans. Escalating deforestation is already reducing Amazon rainfall, putting aquifers and agribusiness at risk. Agricultural producers also fear global consumer perceptions of Brazil as being anti-environmental could lead to a backlash and boycotts.

COP24: Nations complicit in ignoring bioenergy climate bomb, experts say
- Twenty years ago science told policymakers that bioenergy – the burning of woody biomass – was a sustainable form of energy that was carbon neutral. The current United Nations carbon accounting system follows that guidance. However, new science has found the hypothesis to be wrong: bioenergy has been found to add significantly to carbon emissions.
- However, national delegations at the UN climate summit in Poland, COP24, as they wordsmith the Paris Rulebook, are stonewalling on the matter, doing nothing to close the bioenergy carbon accounting loophole. But nature can’t be fooled, which means that the undercounting of emissions could push the world past a climate catastrophe tipping point.
- Still, with the problem unaddressed, developed nations in the European Union and elsewhere continue burning woody biomass as energy, with the U.S., Canada and other nations happy to profit from the accounting error. Tropical nations like Brazil and Peru are eager to jump on the bioenergy bandwagon, a potential disaster for rainforests and biodiversity.
- Meanwhile, NGOs and scientists at COP24 have sought earnestly to alert the media and COP delegations to the bioenergy climate bomb and its looming risks, even going so far as to write language closing the loophole that could be inserted into the Paris Rulebook now being negotiated, but to no avail.

COP24: Trumpers tout clean coal; protesters call it ‘climate suicide’
- As in 2017, the Trump administration delegation was again at COP, seriously praising coal as a climate solution in a public presentation Monday – but behind the scenes the U.S. delegation is reportedly less incendiary and more cooperative. The Polish government is also heavily promoting the dirtiest of fossil fuels at the two-week-long Katowice event.
- But protestors, subnationals and NGOs are having none of it. COP24 participants treated the Trump administration coal public presentation with outrage, as a freakish sideshow and a joke. They used the event to send the message that decarbonization is the only way forward – as a means of curbing climate change, while boosting local economies and creating jobs.
- “It’s ludicrous for Trump officials to claim that they want to clean up fossil fuels, while dismantling standards that would do just that,” said Dan Lashof, director, World Resources Institute US.
- “More and more companies are committing to renewable energy, reducing emissions, and striving for a just [energy] transition that protects the wellbeing of all workers,” said Aron Cramer, CEO of BSR, a sustainability consulting firm in San Francisco.

COP24: US, Russia, Saudis downplay IPCC report in display of disunity
- The U.S., Russia, Saudi Arabia, and Kuwait rejected language strongly affirming the severity of global warming at the COP24 summit in Poland on Saturday night. The United States is in the process of withdrawing from the Paris Climate Agreement, while Russia has failed so far to ratify the accord.
- Some fear this could signal further obstruction this week by major oil producing nations as national leaders arrive at COP24 to wrestle with resolving a host of difficult issues, including an upping of Paris carbon-reduction pledges, completion of the Paris Rulebook measuring energy production, transportation, agriculture, and deforestation to curb climate change.
- Also, to be worked out, transparency rules on emissions, and plans for wealthy nations to help support poor nations adapt to climate damage. This daunting agenda isn’t helped by the leadership void created when the U.S. pulled back from the Paris agreement after Democrat Barack Obama was replaced as president by Republican Donald Trump.
- At COP24, Tom Steyer, a prominent U.S. environmental activist, said that “nothing short of transformational politics” in the United States will get international climate action back on track. He sees U.S. leadership as essential to preventing the worst impacts of global warming. But such a sea change won’t likely come until after the 2020 presidential election.

COP24: World’s nations gather to grapple with looming climate disaster
- Representatives from nearly 200 nations gathered in Katowice, Poland on Sunday for COP24, the annual meeting of the Conference of the Parties, to move forward on climate action. The goal: keep global temperatures from rising less than 2 degrees Celsius (3.6 degrees Fahrenheit) by 2100.
- Unfortunately for the planet, the COP mechanism has stalled since its 2015 triumph in Paris when the world’s nations agreed to work together to cut carbon emissions. To date, just seven nations, most of them tiny, are on track to reduce emissions to meet the 2 degree Celsius goal, while the U.S. is on track to withdraw from the accord by 2020.
- Today, subnationals – cities, states, regions, businesses, faith organizations, indigenous groups, and NGOs – are providing much of the initiative and impetus for cutting emissions. They are working together in a variety of ways, to reduce deforestation and improve agricultural land use, for example. They will have a major presence at COP24.
- But while subnational efforts are commendable and important, they are not near enough, experts say. With the UN Intergovernmental Panel on Climate Change, and other scientific organizations, publishing increasingly dire forecasts, urgently calling for climate action, it is vital that nations prioritize climate action and move quickly to decarbonize their economies.

World’s first indigenous carbon offset project suspended due to illegal mining
- In 2009, the Paiter-Suruí of Brazil became the first indigenous group in the world to design and implement a major forest conservation and carbon storage and offset project, a set of initiatives financed by selling carbon-offset credits..
- On Monday, the Paiter-Suruí announced the project is being suspended indefinitely due to an onslaught of diamond and gold miners and loggers which has caused a dramatic surge in deforestation within their 248,147 hectare (958 square mile) territory.
- In its early years, the project – designed to prevent at least five million tons of carbon emissions in 30 years – was incredibly successful. Illegal logging in the indigenous territory dropped to almost zero from 2009 to 2012, a period during which surrounding regions saw deforestation rates more than double.
- Analysts cite multiple reasons for the project suspension: the intrusion of external, powerful, self-interested actors; the lack of law enforcement in the indigenous territory; and the lack of state investment in indigenous education, health, and livelihood programs that could have alleviated individual economic and social pressures to secure short-term financial gain.

Improving rural credit in Brazil: More production, better environment (commentary)
- One of the biggest challenges for the global economy is to use natural resources more efficiently, increasing food and energy production while preserving the environment.
- Brazil is at the center of this process, since it has abundant natural resources and is one of the largest agricultural producers in the world—the fourth largest according to FAO (2016). Controlling deforestation and greenhouse gas emissions and strengthening the agribusiness should occur together.
- The primary public policy for Brazilian agriculture is rural credit. A thorough analysis of the rural credit system shows the need to reform the policy, simplify the rules, improve distribution channels, and more closely align it with the Brazilian Forest Code.

New research calculates full carbon cost of oil palm cultivation in Indonesia’s forests
- Researchers found that each hectare of rainforest converted to oil palm monoculture creates 174 tons of carbon emissions, most of which will find their way into the atmosphere and contribute to global climate change.
- After oil palm is harvested, the amount of biomass returned to the soil to feed living organisms underground can be 90 percent lower than in a functional, healthy rainforest. Since the soil in oil palm plantations is repeatedly cleared and treated with pesticides, very little natural litter like dead leaves and wood goes back into the ground.
- The research team said that their findings show that figures used by bodies like the IPCC and the RSPO to calculate the carbon cost of oil palm cultivation should be updated and that belowground carbon losses must be accounted for.

Consensus grows: climate-smart agriculture key to Paris Agreement goals
- Attendees at the annual Global Landscape Forum conference in Bonn, Germany, this week sought approaches for implementing “climate-smart” agricultural practices to help keep global temperature from rising more than 2 degrees Celsius (3.6 degrees Fahrenheit) by 2100.
- Some 40 percent of the earth’s surface is used for food production, with 400 million small farmers worldwide, plus industrial agribusiness, so policymakers understand that climate-smart agriculture, practiced broadly, could play a significant role in reducing carbon emissions and helping nations meet their Paris carbon-reduction pledges.
- Numerous agricultural management practices to reduce carbon emissions, enhance food security, productivity and profitability, are available now. They include wider use of cover crops, low and no till techniques, increased application of organic fertilizers such as manure, judicious use of chemical fertilizers, and the growing of crops bred for climate resiliency.
- These techniques are already being embraced to a degree in the U.S. and globally. Land of Lakes and Kellogg’s, for example, are insisting on sustainable farm practices from their suppliers, while John Deere is building low-till equipment that allows for “precision farming,” optimizing returns on inputs while preserving soils and soil carbon.

Renewable energy to power 139 countries? Scientists say it’s possible
- The research looked at the impacts of a 100-percent switch to renewable energy in 139 countries by 2050 on the climate, as well as air pollution and the economy.
- They calculated that the transition to wind, solar and hydropower will generate around 24 million net jobs.
- Switching to renewable sources of energy that don’t emit carbon into the atmosphere will also save trillions of dollars in the costs we would otherwise incur due to air pollution and the changing climate.

Burning wood: Can the EU see the forest for the trees?
- A new report argues that forests need more protection from the biomass industry in the EU, which is deforesting the American south to produce energy abroad.
- EU policy considers burning woody biomass as carbon neutral, even though other countries and many scientists say that doesn’t add up.
- Demand for wood pellets in the EU is growing: last year, the UK imported 8 million tons. This demand is leading to high quality wood – not waste – being burned.

WWF and National Geographic ask: ‘How much stuff do you need?’

Seven billion people inhabit the planet and all require food and water, but less than one percent of the water found on the planet is fresh and accessible and 70 percent of that goes to growing crops. Meanwhile temperatures are rising worldwide due to the overuse of fossil fuel energy. Given these issues, a new […]
