Key developments

Deforestation dropping, but not fast enough

LOSING FOREST: The world lost almost 11m hectares of forest each year over the past decade – an area almost the same size as Iceland, the UN Global Forest Resources Assessment found. The overall rate of deforestation slowed over 2015-25 – compared to annual losses of 13.6m hectares over 2000-15 and 17.6m hectares over 1990-2000. [Carbon Brief will publish an article later this week detailing more key findings.] Elsewhere, a different UN report found that annual spending on forests must more than triple to $300bn by 2030 to meet climate and nature goals.

POOR PROGRESS: At the same time, a third report found that more than 8m hectares of forest was destroyed in 2024 – which is 63% above the trajectory needed to put an end to deforestation by 2030. The Forest Declaration Assessment report said that countries are off track to meet a pledge from more than 100 countries to halt and reverse global deforestation by 2030. It noted that agriculture caused 86% of global deforestation in the past decade. In its coverage of the report, Climate Home News noted that experts said the findings were a “wake-up call” ahead of COP30 in the Amazon.

FOREST FINANCE: An investigation from Global Witness found that banks and asset managers around the world generated $26bn from “financing deforesting companies” through investments, loans and other financial services between 2016 and 2024. US financial institutions earned the biggest gains, it said. Elsewhere, the EU “u-turn[ed]” on plans to delay its anti-deforestation law until 2026, instead suggesting tweaks to allow more time for compliance, according to Politico. Separately, an NGO report found that timber imports from companies operating in the EU “can be traced to logging on Indonesia’s Borneo island”, Agence France-Presse said.

Nature congress 

EXTINCTION RISK: A new global assessment published by the International Union for Conservation of Nature (IUCN) found that more than 60% of the world’s bird species are in decline, the Guardian reported. In 2016, the equivalent figure was 44%. The outlet underscored that deforestation, largely bolstered by the expansion of agriculture and human development, is the main cause of falling populations. The Washington Post added that Arctic mammals, such as seals, whales and polar bears, are also “increasingly threatened by extinction” due to pressures from climate change.

SIGNIFICANT IMPROVEMENT: The IUCN report also showed some “bright spot[s]”, as is the case with green sea turtles, which “have recovered substantially thanks to decades of conservation efforts”, explained the Washington Post. A scientist leading the sea turtle assessment told the New York Times that the rebound “comes down to reducing threats”. As another example of species recovery, the outlet pointed to the island of Rodrigues in the Indian Ocean, where two bird species on the brink of extinction are now listed as species of least concern, thanks to restoration work carried out by conservationists.

BIODIVERSITY CONGRESS: The report was published against the backdrop of this year’s IUCN congress on biodiversity conservation, which saw members adopt a 20-year strategic vision that boosts human rights and social justice alongside conservation, according to the IUCN. EFE Verde reported on the congress, where there was a call to action for countries to speed up the implementation of the Kunming-Montreal Global Biodiversity Framework and to ensure that 30% of the planet is protected by 2030. However, new analysis from Carbon Brief showed that just 28% of countries have submitted their plans for biodiversity conservation to the UN a year after the deadline.

News and views

WILDFIRE WATCH: The annual “state of wildfires” report found that extreme wildfires released more than 8bn tonnes of CO2 during the March 2024-February 2025 global fire season. The report, published by an international team of scientists and covered by Carbon Brief, showed that wildfires covered at least 3.7m square kilometres – an area larger than India – and exposed more than 100 million people around the world to these extremes.

BIOFUEL BOOST: At COP30, Brazil is expected to ask countries to quadruple their use of “sustainable fuels” over the next decade, including biofuels, biogas and hydrogen, as reported by the Guardian. A leaked document seen by the outlet revealed that Brazil argues biofuels will displace fossil fuels. However, biofuels – which are fuels derived from organic matter – are considered controversial by environmental experts, due to their potential to increase deforestation and promote monocultures, the outlet added. Separately, a new Carbon Brief Q&A explored how countries are using biofuels to meet their climate targets.

AGRIBUSINESS MOVE: Brazil’s agribusiness – the largest emitting-sector in the country and a major driver of deforestation – plans to present the country as a leader in sustainable agriculture at the upcoming COP30, Bloomberg reported. The farm lobby faces international pressure from policies such as the EU law that requires Brazil to ensure that its crop exports are free from deforestation, the outlet said.

LONG LIVE THE WHALES: A “historic lawsuit” to protect whales in the Gulf of California has been accepted for a hearing by two district courts in Mexico, Animal Político reported. The suit aims to declare the area a “critical habitat” and rule that previously granted permits for shipping liquefied natural gas through the gulf are unconstitutional. El País also covered the news and added that a coalition of civil-society organisations is advocating for the recognition of whales as “subjects of rights”.

LARGE EMISSIONS: In 2023, 45 major meat and dairy companies emitted more than 1bn tonnes of greenhouse gases, comparable to the emissions of top fossil-fuel producers, according to a new report by civil society organisations. The report found that the top five highest-emitting firms – JBS, Marfrig, Tyson, Minerva and Cargill – were responsible for 480m tonnes of CO2-equivalent emissions. The 45 firms’ methane emissions exceeded those from the EU and UK, it added. Elsewhere, Nestle withdrew from a global alliance of dairy producers for reducing methane emissions, without providing a reason, Reuters reported.

PRICE HIKE: Over the past year, extreme weather has driven up prices by 16% for five products – butter, beef, milk, coffee and chocolate – together responsible for 40% of food inflation over that time, according to research covered by the Daily Mail. The outlet said that “alternating periods of drought, extreme heat and heavy rainfall are affecting farmers” globally. The Financial Times also covered the report, writing that its “findings challenge the narrative promoted by industry groups that have linked high grocery bills to domestic policies”.

Researching climate impacts on Thai tree seeds

This week, Carbon Brief details how Kew Gardens researchers are studying the effects of extreme heat and drought on trees in Thailand.

Forests in Thailand, as in many other parts of the world, are feeling the effects of climate change – from the country’s mountain peaks in the north to its mangroves on the southern coast.

Scientists at Kew Gardens are assessing how certain tree species react to high temperatures and drought to help inform efforts in re-planting degraded forests across the country.

The is one of several projects from Kew’s Millennium Seed Bank, which this week marks its 25th anniversary. It is the world’s largest collection of wild plant seeds, holding almost 2.5bn seeds from 40,000 different species.

Incubating seeds

For the Thailand project, researchers collected 60,000 seeds from three tree species growing across the country. They focused on tree types which benefit local people, such as the Sapindus rarak, whose seed can be used as a washing detergent.

The scientists sought seeds from areas with “different climates and altitudes” – ranging from the country’s highest mountain, Doi Inthanon, to its lowlands – to try to find out which areas yield resilient seeds, Dr Jan Sala, a researcher at the seed bank, told Carbon Brief.

The Kew team is collaborating on the project with the Forest Reforestation Research Unit (Forru), a research team at Chiang Mai University in Thailand that restores degraded forests.

The researchers are still analysing their data and hope to publish the findings next year, but Sala said initial observations show some “interesting” differences in how the thousands of tree seeds respond to warming and drought. He told Carbon Brief:

“We cannot say this for sure because we have not finished the analysis, but hopefully we identify a couple of populations…that are resilient to climate change.”

To study this, they put each of the thousands of seeds into incubators and subjected them to temperatures ranging from 5C to 50C across different periods of time. They wanted to see how the seeds germinate under various conditions and identify “whether a population or species reacts differently to temperature rising”, Sala says.

Building resilient forests

Dr Inna Birchenko, a research associate at the Millennium Seed Bank who was also involved in the project, told Carbon Brief that the Thailand study findings can help to ensure that restored forest plots have the “best chance for long-term survival”.

She noted that resilient forests “contribute to decarbonisation by locking carbon in the trunks, as opposed to just being a wasteland or being an agricultural land”.

Sala said the researchers hope to not only help Forru decide which seeds to use in different restoration projects, but also provide more information to “all practitioners across Thailand”.

Birchenko noted that while temperate trees are generally well-researched, tropical species are “so understudied”. She told Carbon Brief:

“Every day, I’m trying to find extra information about the genetics of this or that species, and there is absolutely nothing…So we are hoping that this potentially snowballs into more effort into this area.”

Watch, read, listen

FLYING HIGH: A Guardian article visualised how bird migration around the world is being reshaped by “new threats”, including climate change.

ON THE MOVE: Yale Environment 360 explored how US border-wall construction is “creating a roadblock” to the return of jaguars in the country’s south-west as Mexico’s populations recover.

OVERFISHING ISSUES: An article in Vox looked at how nature conservation projects in Madagascar could be reshaped to prevent them “mak[ing] it harder for desperately poor people to make a living”.
VALUABLE VOCABULARY: An Atmos video addressed a study on how the English language is losing nature-related words, undermining people’s connection to nature.

UN chief urges countries to adopt fossil fuel transition plans with timelines

Published

on

The head of the United Nations has called on all countries to deliver plans for phasing out their production and consumption of fossil fuels, as rising oil prices and climate shocks threaten energy and human security.

In his farewell speech to the UN General Assembly (UNGA) in New York on Tuesday, outgoing UN Secretary-General António Guterres for the first time urged “every government to adopt a national plan to transition away from fossil fuels” aligned with limiting warming to 1.5C. The plans, he said, should include “clear timelines and protection for affected workers and communities”.

“We know fossil fuel interests won’t step aside on their own. For decades, Big Oil has treated the atmosphere as an open sewer – and cashed in on the consequences,” Guterres told diplomats in his speech opening the leaders’ segment of the assembly, also calling out the industry’s windfall profits after Russia’s invasion of Ukraine.

    At last year’s COP30 climate summit in Belém, a group of about 80 governments led a failed push to develop a global roadmap to transition away from fossil fuels. Brazil instead proposed to draft a voluntary report that will be presented this year ahead of COP31 after countries and organisations submitted their views to the process.

    Governments first agreed to transition away from fossil fuels in energy systems at COP28 in Dubai in 2023, but have since failed to agree at UN climate talks on how to move forward with that commitment, as efforts to do so have been effectively blocked by large fossil fuel-producing countries.

    France, Netherlands issue plans

    A few countries have moved forward with their own transition plans. France launched the first one at an international conference on the issue in April and the Netherlands followed suit this month. Not being major fossil fuel producers, both European nations aim to end their coal, oil and gas consumption by 2050, although the Dutch plan was criticised for not setting specific phase-out dates for the dirty fuels.

    Adão Soares Barbosa, climate ambassador from Timor-Leste and chair of the Least Developed Countries (LDC) group in the UN climate negotiations, told a press briefing on Tuesday that last year’s discussions on shifting away from fossil fuels need to continue at COP31, adding that developed countries should lead the way with transition plans and curb their use of fossil fuels.

    “We are expecting that we can make a request to major-emitting countries to limit emissions from this sector,” he said. “For LDCs, we’ll also try to reduce fossil fuel use, but it will depend on national circumstances.”

    Samoa’s lead negotiator Anna Rasmussen said small island states have outlined their energy transition plans in their nationally determined contributions (NDCs) – countries’ plans for meeting the Paris Agreement goals – but added “we’re still waiting” for climate finance to help implement those plans.

    Despite the global push to clean up the energy mix, countries leading climate talks are themselves also expanding fossil fuel production. COP31 co-presidents Australia and Türkiye have both recently given the green light to mine and drill more coal, oil and gas, and still depend on fossil fuels for 60% and 56% of their electricity production respectively.

    Fossil fuel expansion threatens COP31 hosts’ credibility, experts warn

    COP30 host nation Brazil has also persisted with its plans to explore potential new oil reserves near the mouth of the Amazon River – a region known as the Equatorial Margin.

    These are moving ahead despite President Luiz Inácio Lula da Silva announcing last year at the Belém climate summit that the country would develop its own fossil fuel phase-out plan. This is still under development with little information about its progress and may be hampered by elections next month.

    “We have achieved our self sufficiency in oil and will continue to explore the potential of new reserves, such as those in the Equatorial Margin,” Lula said in his speech to the UNGA on Tuesday. “But we will not abandon the environmental agenda,” he insisted. “We will move forward with the roadmap for the decarbonisation of the Brazilian economy.”

    Transition far cheaper than status quo

    Speaking at the main Climate Week NYC venue, Mads Christensen, executive director of Greenpeace International, said given the fast-shifting cost dynamics for both fossil fuels and renewables, countries should revise their existing energy plans because they are now out of date.

    Gas power generation now costs around 150 euros per megawatt compared with around 50 euros for solar with battery storage – making the latter two-thirds cheaper.

    “If these plans were updated, I think we would have a much faster transition because it simply makes good financial sense,” he said.

    Tzeporah Berman, founder and chair of the Fossil Fuel Treaty Initiative, told Climate Home News that the Santa Marta process for transitioning away from fossil fuels (TAFF), launched at April’s conference, could help countries discuss, design and develop their national roadmaps, as well as mobilise the international cooperation required to actually deliver them.

    “Many countries want not only national roadmaps but a global roadmap off the highway to hell,” she added. “A global plan is necessary to ensure the rules aren’t rigged against those who want to do the right thing and so all countries can make credible commitments.”

    The second TAFF conference will be held in the Pacific island nation of Tuvalu next spring, co-chaired by Ireland. In New York, Tuvalu’s climate minister Maina Vakafua Talia called for stepped-up efforts to tackle the fossil fuel use that is threatening his country’s “demise” by driving global warming.

    “The world is running out of time, and so I ask every government to come to… Tuvalu with solutions – real solutions, not false solutions – for us to ensure that we have a pathway and a way forward,” he urged.

    COP31 electrification pledge leaves out clean power commitment

    Published

    on

    COP31’s flagship initiative to accelerate the electrification of the world’s economy has been criticised for failing to include a commitment to produce the power from clean energy.

    Governments that sign the voluntary pledge at this year’s UN climate summit will commit to increasing electricity’s share of total energy consumption to 35% globally by 2035 in line “with pathways consistent with keeping 1.5C alive”, the text unveiled by the Turkish presidency on Tuesday says.

    While the document says that the electrification goal is “complementary to efforts to expand renewable energy and improve energy efficiency”, governments are not explicitly asked to commit to producing the extra power with clean sources and driving down greenhouse gas emissions.

    The text instead says the “use of clean electricity” will vary according to national circumstances. Fossil fuels are not mentioned by name, although the pledge cites the COP28 Global Stocktake decision, which called for “transitioning away from fossil fuels” in energy systems.

      COP31 president Murat Kurum said earlier this month that the push to make electrification more “widespread” – through measures like the rollout of electric vehicles and heat pumps – will “automatically” lead to a reduction in the use of fossil fuels.

      But many campaigners disagree, criticising the proposed pledge for failing to give an explicit signal on the fossil fuel transition.

      Lack of clarity on energy sources

      “Let’s not let electrification become the Trojan horse of our times, used to hide new fossil fuel consumption rather than promote renewable energy,” Claire Smith from civil society umbrella group Beyond Fossil Fuels said in reaction to the pledge’s publication.

      She added that the commitment will only help address the climate crisis if electrification is powered by a flexible energy system where solar and wind are complemented by enhanced grids and storage.

      The pledge’s text says that the electricity goal should be supported by “diverse and sustainable energy sources”, but it stops short of explaining what these sources are.

      Alden Meyer, an international climate policy expert and senior associate at think-tank E3G, said the details of the pledge matter to how effective it will be in helping bring planet-heating emissions down.

      “It has to be clean, and we haven’t got enough clarity on a guarantee that it will be a decarbonisation move,” he told Climate Home News.

      China’s industrial engine starts to break its fossil fuel habit

      According to an annual electricity review from energy think-tank Ember, in 2025 renewables edged ahead of coal power for the first time in 100 years. Continued growth in solar and wind pushed the share of renewables above a third of global electricity generation to just under 34%, compared with coal at 33%, it said.

      Janet Milongo, energy Transition lead at CAN International, said success cannot be measured simply by how much of the world’s final energy consumption becomes electric.

      “We must ask what generates that electricity, who has access to it, who owns the infrastructure, and whether it is helping communities transition away from fossil fuels,” she added.

      Electrification alone can’t meet climate goals

      Analysis published by the IEA on Tuesday, alongside the pledge, found that it would already be cost-effective to raise electricity’s share of global energy use from 23% today to around 33% with existing technologies, putting the COP31 goal “within striking distance”. Based on current policies, however, the share reaches only about 30% by 2035.

      Hitting the 35% target would cut fossil fuel importers’ import bills by around $400 billion a year by 2035, the IEA said. At the higher prices caused by the conflict in the Middle East, that saving rises to more than $500 billion.

      Speaking at New York Climate Week on Tuesday, IEA executive director Fatih Birol said the agency’s figures show that in 2026, about 80% of all new power plants built will run on renewables, with a few percentage points coming from nuclear power and the rest from fossils fuels. “So therefore, electrification itself will lead reduction of the [greenhouse gas] emissions,” he added.

      However, the IEA warned in its new report that electrification “by itself is not enough” to meet the world’s climate targets. It noted that, if “low-emission” sources of power continue to simply grow in line with current policy scenarios, that would be only just enough to cover the extra demand from electrification, driving a modest decline in emissions.

      Matt Webb, associate director of global clean power diplomacy at E3G, said the pledge is a “welcome signal of leadership” and can help COP31 be a “critical moment” for countries to double down on the energy commitments made at COP28.

      But to secure the full benefits of electrification, he added, it is essential that we “urgently clean up” by speeding up the rollout of renewables and developing credible national plans to transition away from fossil fuels.

      As loss and damage fund stalls, Nepal crowdfunds flood relief

      Published

      on

      People around the world have donated almost $90 million to a government-led campaign to help Nepal recover from its recent devastating Himalayan flood, according to a Nepali climate negotiator, even as the UN chief slammed the tiny amount of money in a new fund to deal with such disasters.

      Individuals and companies from Nepal and abroad have chipped in from $5 to “many millions” of dollars to the Prime Minister’s Disaster Relief Fund, Manjeet Dhakal, an advisor to the poorest countries at UN climate talks, told an event on Monday focused on early warning systems.

      The prompt and substantial response from the public contrasts with the slower, more limited support that is potentially on offer from the UN’s new Fund for Responding to Loss and Damage (FRLD), set up by governments to compensate developing countries for climate disasters.

      Comment: Human security relies on adapting to the world’s new climate reality

      Over three weeks have passed since Nepal’s finance and environment ministers asked the FRLD board to take an urgent decision to allocate funding to help Nepal protect people and restore essential services in the wake of the disaster, which caused around 1,450 deaths and left more than 5,000 people missing.

      “Time is of the essence,” the ministers wrote in an appeal to the FRLD on August 31, which was swiftly followed by a letter from a group of developing-country board members urging the FRLD board’s co-chairs to organise an extraordinary meeting to come up with a response.

      Loss and damage fund hesitates

      Yet, despite informal online meetings, the co-chairs have yet to convene a meeting with the power to allocate funds. The board’s next scheduled meeting begins on December 15.

      Dhakal said on Monday that the request has “received some positive response, but still there is some discussion ongoing about how to respond to that”.

      “If they can’t respond in a timely manner, then is [the fund] fit for purpose in terms of disasters that the world would be facing in the coming years? The scale and intensity of these disasters is increasing,” he said.

      With just $820 million pledged to it by rich countries and not all of that yet delivered, the FRLD has earmarked just $350 million to spend in its initial phase and without further contributions could run out of money next year.

      Because of these limited funds, and a huge number of requests for funding totalling nearly $3 billion, the FRLD has said it will only give out a maximum of $20 million to each project for now. It has yet to approve funding for any projects.

      Dhakal recently told The Nation magazine that this amount was just a “symbolic gesture”. Nepal’s government has estimated the costs of recovery and reconstruction at $4.8 billion, with homes, roads, bridges, hospitals and hydropower stations in the affected area needing to be repaired and rebuilt.

      “Ridiculously small” funding

      In a speech to the UN General Assembly on Tuesday, the body’s outgoing Secretary-General António Guterres criticised the “ridiculously small” level of funds made available by wealthy governments to the FRLD. Developed countries should “make the loss and damage fund work at scale”, he said.

      The Portuguese diplomat told world leaders that when he travelled to Nepal three years ago, he had “sounded the alarm on accelerating glacier melt, warning that the rooftops of the world are caving in”.

      “Some dismissed it all as overstating dangers, but as tragic events have shown, impacts are arriving sooner, hitting harder, and spreading further than many anticipated,” he said.

      A recent study by scientists with the World Weather Attribution group found that climate change contributed to the rock-ice avalanche which sparked a huge flash flood along a river valley on the Nepal-Tibet border.

      Speaking at a separate event in New York on Monday, leading climate scientist Johan Rockström highlighted those findings on the role of global warming in the Himalayan disaster.

      “This will be potentially the first poster-child case of a loss and damage invoice, because here we have a proven case of a catastrophe which would not have occurred if it hadn’t been for human-caused climate change,” he said.
