Key developments
China’s role at COP29 and beyond
‘COOPERATIVE’ COP: China’s “role” at the COP29 climate talks, which concluded over the weekend in Baku, Azerbaijan, was “markedly different to previous years”, with its negotiators being “unusually cooperative”, according to an anonymous “chief negotiator” for a “powerful” country quoted by BBC News. Bloomberg cited sources “close to the Chinese delegation” explaining that “Chinese officials moved to soothe angry delegations from India, Saudi Arabia, Africa and the small island group” during the tense final plenary. It added that China’s delegation head Zhao Yingmin, who is also the vice minister of the Ministry of Ecology and Environment (MEE), held “one-on-one conversations with delegates in the final hours to warn things would be worse without COP29’s finance agreement”. COP29 president Mukhtar Babayev wrote in the Guardian that China “coordinat[ed] their response to the negotiations…with the G77 group”. Babayev also claimed that “the Chinese were willing to offer more [climate finance] if others did so too”. (For more on China’s role at COP29, see the Spotlight.)

GLOBAL CALLS: As concerns over the US’s future role loomed over the two-week summit, UN climate chief Simon Stiell said the world “will need China’s continued leadership” to meet climate goals, Politico reported. This was echoed by South Africa’s environment minister, who said China “has an opportunity to lead the global fight against climate change”, according to Bloomberg. BBC News quoted Jonathan Pershing, program director of environment at the William and Flora Hewlett Foundation, saying that, should China become the de-facto leader at future COPs, it “won’t lead from the front, like the US and Europe”, but instead would “discreetly interven[e] to unblock disputes…behind closed doors”.
CHINA’S REACTION: In response to Stiell, Politico quoted Zhao saying: “China has contributed in addressing climate change. But, in the future, China will do our best to contribute more.” Zhao also said in an interview with business news outlet 21st Century Herald that China will be “the backbone of the global response to climate change”. Nevertheless, Chinese climate envoy Liu Zhenmin told Beijing News that “people expect China and the EU to work together to fill this gap [of US leadership], which is a very good wish, but, in practice, it is very difficult”. (Read more in the Spotlight below.) China’s foreign ministry noted that agreements at COP29 demonstrated global “willingness” to address climate change, although it added that developed countries should “effectively fulfil their obligations and responsibilities”, Shanghai-based news outlet the Paper said. A commentary in the party-affiliated People’s Daily under the nom de plume “Heyin”, which is used for articles expressing the view of party leadership on international affairs, said COP29 “consolidated the momentum” of the global energy transition, adding that “no matter how the [geopolitical] climate changes, China’s determination…to actively address climate change will remain unchanged”. Elsewhere, an editorial in the state-run newspaper China Daily argued COP29 was an “unusual climate diplomacy success” as it broke “the long-standing multilateral negotiations stalemate over climate financing”.
New China research
EARLY PEAK: Meanwhile, on the sidelines of COP29, an assessment by research institute the Centre for Research on Energy and Clean Air (CREA) of China’s energy transition in 2024 found that the clean energy industry “continued to exceed forecasts”, but that spiking energy consumption meant record additions served only to “stabilise emissions, not to push them down”. It added that 52% of experts surveyed by CREA expected China’s coal consumption to peak by 2025 and 44% believe China’s carbon emissions have already peaked or will peak by 2025.
POLLUTING PROVINCES: Al Gore-backed research institute Climate Trace released a report finding that Shanghai was the world’s “most polluting” city, Fortune said. It added that “seven states or provinces spew more than 1bn metric tonnes of greenhouse gases [per year]”, six of which are in China – the exception being Texas.
POWER SYSTEM REFORM: The International Energy Agency also presented a report at COP29 examining the “evolving flexibility requirements of China’s power system” during its energy transition, finding that “non-fossil resources, such as hydropower, battery storage and demand response, could fulfil nearly 60% of [China’s] short-term flexibility needs by 2030”, according to a press statement.
‘INSUFFICIENT’ SPEED: The 2024 Global Carbon Neutrality Progress Report, released by Beijing’s Tsinghua University, evaluated progress in 151 countries that have set carbon neutrality targets. The report said that developing countries have higher “ambitions” and willingness to reduce emissions than developed countries. However, it added that the “current speed of renewable energy development globally is insufficient” to meet the target of tripling renewable energy capacity by 2030 – a goal set at COP28 in an effort to limit global warming to 1.5C.
Xi at APEC and G20
SUNNIER CLIMES: As his subordinates hashed out details in Baku, President Xi Jinping’s attendance of the APEC economic leaders’ meeting in Peru and G20 summit in Brazil “fuelled expectations that China will continue championing…better global governance”, China Daily said, adding that during APEC Xi “emphasised the importance of innovation, openness, green development and inclusive growth”. Xi also inaugurated Peru’s Chancay port – built by a Chinese company – as Beijing “look[s] to further tap into resource-rich Latin America”, Reuters reported. At the G20 summit, Xi noted the importance of supporting developing countries in “responding to…climate change, biodiversity loss and environmental pollution”, state news agency Xinhua said. China also signed 37 agreements with Brazil, according to the Associated Press, which included specific agreements on mining, solar and nuclear power.
UK-CHINA TIES: In the first high-level meeting between the UK and China since 2018, UK prime minister Keir Starmer told Xi that the UK “would like to engage with Beijing on areas such as trade, the economy and climate”, Reuters reported. Starmer told the UK House of Commons that the two countries need to “work together on challenges such as climate change and delivering growth”, adding that he and Xi “agreed a new dialogue on these issues, which [UK chancellor Rachel Reeves] will take forward with vice premier He [Lifeng] in Beijing” next year, according to a transcript of his remarks.
‘Disorderly expansion’ of solar factories targeted
RAISING REQUIREMENTS: China’s Ministry of Industry and Information Technology (MIIT) raised minimum capital requirements for construction and expansion of solar-manufacturing projects, the Hong Kong-based South China Morning Post said, adding that MIIT also urged manufacturers to limit projects that are “merely meant to increase capacity”. Lin Boqiang, director of Xiamen University’s China Energy Policy Research Institute, told business news outlet Yicai the move will “control the disorderly expansion of production capacity”.
LOWERING REBATES: China’s finance and tax bodies also “announced a reduction in the export tax rebate” for solar products, “squeezing profit margins” and possibly leading to companies “increasing export prices”, PV Magazine reported, in what may be “part of a longer-term strategy”. Finance news outlet Wall Street CN noted that rebates for batteries will also shrink, but that manufacturers will still have a “price advantage in overseas markets”.
EXPERT VIEWS: Liu Shijin, former vice-president of the Development Research Centre (DRC) and chief advisor at the China Council for International Cooperation on Environment and Development (CCICED), said in a speech covered by Yicai that “overcapacity” is a “normal process of market competition”, adding that the government should avoid “disturbing” industries through “administrative intervention and unfair competition”, and instead encourage market expansion by “accelerating the shift from dual-control of energy consumption to dual-control of carbon emissions”.

COP29: How China approached the UN climate talks in Baku
As ever at COPs, a key question was how the world’s current largest annual emitter, China, would approach the talks. This year, with Donald Trump being reelected as the US president, more expectations fell on China to step up and do more.
In this article, Carbon Brief summaries some of the key points China made at COP29. This is a summary of “China at COP29” in Carbon Brief’s in-depth summary of the event’s key outcomes.
China arrived at the COP29 UN climate talks in Baku with the fifth-largest delegation, continuing its recent trend of major showings at the annual summit.
At the high-level opening of the talks, China’s vice premier Ding Xuexiang – who is president Xi Jinping’s “special representative” at COP – declared that his country had “provided and mobilised project funds of more than 177bn yuan ($24.5bn) for developing countries’ climate response” since 2016.
This was the first time China used the language of climate finance to talk about its overseas aid. It quickly drew attention to Beijing’s intentions and levels of ambition for climate finance.
Kate Logan, director of the China climate hub at the Asia Society Policy Institute (ASPI), wrote on Twitter that this placed China “on the same order – if not higher than – many developed countries’ efforts” on climate finance.
Dialogue Earth reported that Beijing has contributed more than $30bn to global climate finance since the launch of its “Belt and Road Initiative”, putting China “on a par with the UK, to become the joint fifth-largest provider of climate finance after Japan, Germany, the US and France”.
However, entering week two, China’s stance on climate finance remained firm – it said it would not agree to make any compulsory contributions, including to the new climate finance goal (NCQG) that was being negotiated at the summit.
China’s new climate envoy Liu Zhenmin, replacing Xie Zhenhua, told the Paper, a Shanghai-based outlet, that paying for the NCQG was “their business”, referring to developed countries.
During the closing stages of COP29, Xia Yingxian, director of the department of climate change of the Ministry of Environment and Ecology, said that a serious climate finance offer from developed countries was the “master switch and golden key” to a deal in Baku.
Liu was also quoted by state-run newspaper China Daily, saying China is “not obliged to contribute to the post-2025 climate financing target that is expected to be announced during COP29”.
At the closing plenary, Carbon Brief heard Zhao Yingmin, head of Chinese delegation and the vice minister of the Ministry of Ecology and Environment (MEE), saying that developed countries’ NCQG commitments were still “fall far short of meeting the needs of developing nations” and that developed countries’ “financial obligations must be further clarified”.
Nevertheless, China said it remained open to multilateral cooperation on climate change.
Chen Zhihua, deputy director of China’s National Centre for Climate Strategy and International Cooperation, told Carbon Brief that Donald Trump being reelected as the US president “certainly is a big thing that people talk about and [we] have concerns about how things will turn out”.
He added: “It will have big impacts, but China won’t change its strategy – we will cooperate with whoever for global cooperation on climate change.”
Wen Hua, deputy director-general of the Department of Resources Conservation and Environmental Protection at China’s top planner the National Development and Reform Commission (NDRC), said at another event attended by Carbon Brief: “China is willing to take a more active role in global climate governance.”
Throughout COP29, China strongly identified itself as a developing country. China, together with the G77 group of developing counties, rejected an initial draft for the NCQG framework. According to BBC News, they wanted “public grants of $500bn per year”.
At the South-South Cooperation on Climate Change forum hosted by China, Carbon Brief heard Huang Runqiu, minister of the MEE, saying that the world needs multilateral cooperation on combating climate change, but that “green trade barriers” prevent better cooperation, especially for developing countries.
Wang Can, director of the department of environmental planning and management at Beijing’s Tsinghua University, explained to Carbon Brief that the “green trade barriers” are “bans and tariffs…mainly from the US” on renewable technology products.
Both Chinese academics and multiple senior officials expressed their desire for international cooperation on energy transition at COP29.
For example, Wen called the energy transition “fundamental” for China at an event hosted by the country’s COP29 pavilion.
China also stated some of its specific targets and actions for addressing climate change, such as the latest emissions standards for coalbed methane introduced by Liu at a methane summit held during COP29.
Regarding China’s next NDC, an anonymous scholar told Carbon Brief that shifts in the new pledge could lie in “adjusting the timeline of [the] ‘dual-carbon’ goal”, which currently targets a peak in emissions “before 2030” and carbon neutrality “by 2060”. (For more views, see Carbon Brief’s “Experts: What to expect in China’s climate pledge for 2035.”)
China has already adjusted its “dual-carbon” goal from “achieving carbon peak by 2030” to “before 2030”. Bai Quan, director of the Energy Research Institute of the Academy of Macroeconomic Research (AMR), a government-affiliated “national high-end thinktank”, told Carbon Brief that while “we would love to try our best…we can’t rule out all possibilities to peak even earlier than planned”.

China’s historical carbon dioxide (CO2) emissions within its borders are now higher than the 27 member states of the EU combined, new Carbon Brief analysis found, although it is “still far behind” and “unlikely to ever overtake” the US total. The analysis – which was covered by the New York Times under the headline: “China’s soaring emissions are upending climate politics” – noted that when viewed on a per-capita basis, using 2024 figures, China’s contribution is “just 227tCO2 per capita, less than a third of the 682tCO2 for people in the EU27”.

The number of extreme weather events in China that had their “severity or likelihood” increased by climate change, out of a total of 114 attribution studies covering the country, according to Carbon Brief analysis. The figures come from Carbon Brief’s updated “attribution map”, which covers every attribution study published since the method was developed in 2004. The map includes more than 600 studies, with China making up 16%. More than 70% of the China-focused studies were published in the past four years, significantly higher than average.
New science
npj Climate and Atmospheric Science
The number of heat-related diabetes deaths in Chinese cities is expected to increase by the end of the century as a result of global warming, a new study warned. The authors predicted deaths due to extreme heat over 2010-2100 in 32 “major” Chinese cities. They projected that under the low warming SSP1-2.6 scenario, the heat-attributable fraction of diabetes deaths will rise from 2.3% in the 2010s to 4.6% in the 2090s. Under the high warming SSP5-8.5 scenario, the fraction could rise to 19.2% in the 2090s, they added.
Communications Earth & Environment
Electric vehicles in China have nearly a 12% reduction in CO2 as compared to internal combustion engines, according to new research. Researchers carried out a life-cycle analysis of internal combustion engines, plug-in hybrid vehicles and battery EVs in each of China’s provinces. They found that while battery EVs reduced CO2 and nitrogen oxide emissions, they had higher emissions of sulphur dioxide and particulate matter. The authors wrote that “improving technological progress and optimising electricity mix will greatly assist in achieving emissions reduction”.

Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Blazing heat hits Europe
FANNING THE FLAMES: Wildfires “fanned by a heatwave and strong winds” caused havoc across southern Europe, Reuters reported. It added: “Fire has affected nearly 440,000 hectares (1,700 square miles) in the eurozone so far in 2025, double the average for the same period of the year since 2006.” Extreme heat is “breaking temperature records across Europe”, the Guardian said, with several countries reporting readings of around 40C.
HUMAN TOLL: At least three people have died in the wildfires erupting across Spain, Turkey and Albania, France24 said, adding that the fires have “displaced thousands in Greece and Albania”. Le Monde reported that a child in Italy “died of heatstroke”, while thousands were evacuated from Spain and firefighters “battled three large wildfires” in Portugal.
UK WILDFIRE RISK: The UK saw temperatures as high as 33.4C this week as England “entered its fourth heatwave”, BBC News said. The high heat is causing “nationally significant” water shortfalls, it added, “hitting farms, damaging wildlife and increasing wildfires”. The Daily Mirror noted that these conditions “could last until mid-autumn”. Scientists warn the UK faces possible “firewaves” due to climate change, BBC News also reported.
Around the world
- GRID PRESSURES: Iraq suffered a “near nationwide blackout” as elevated power demand – due to extreme temperatures of around 50C – triggered a transmission line failure, Bloomberg reported.
- ‘DIRE’ DOWN UNDER: The Australian government is keeping a climate risk assessment that contains “dire” implications for the continent “under wraps”, the Australian Financial Review said.
- EXTREME RAINFALL: Mexico City is “seeing one of its heaviest rainy seasons in years”, the Washington Post said. Downpours in the Japanese island of Kyushu “caused flooding and mudslides”, according to Politico. In Kashmir, flash floods killed 56 and left “scores missing”, the Associated Press said.
- SOUTH-SOUTH COOPERATION: China and Brazil agreed to “ensure the success” of COP30 in a recent phone call, Chinese state news agency Xinhua reported.
- PLASTIC ‘DEADLOCK’: Talks on a plastic pollution treaty have failed again at a summit in Geneva, according to the Guardian, with countries “deadlocked” on whether it should include “curbs on production and toxic chemicals”.

Factchecking Trump’s climate report
A report commissioned by the US government to justify rolling back climate regulations contains “at least 100 false or misleading statements”, according to a Carbon Brief factcheck involving dozens of leading climate scientists. The report, compiled in two months by five hand-picked researchers, inaccurately claims that “CO2-induced warming might be less damaging economically than commonly believed” and misleadingly states that “excessively aggressive [emissions] mitigation policies could prove more detrimental than beneficial”80

Does Xi Jinping care about climate change?
This week, Carbon Brief unpacks new research on Chinese president Xi Jinping’s policy priorities.
On this day in 2005, Xi Jinping, a local official in eastern China, made an unplanned speech when touring a small village – a rare occurrence in China’s highly-choreographed political culture.
In it, he observed that “lucid waters and lush mountains are mountains of silver and gold” – that is, the environment cannot be sacrificed for the sake of growth.
(The full text of the speech is not available, although Xi discussed the concept in a brief newspaper column – see below – a few days later.)
In a time where most government officials were laser-focused on delivering economic growth, this message was highly unusual.
Forward-thinking on environment
As a local official in the early 2000s, Xi endorsed the concept of “green GDP”, which integrates the value of natural resources and the environment into GDP calculations.
He also penned a regular newspaper column, 22 of which discussed environmental protection – although “climate change” was never mentioned.
This focus carried over to China’s national agenda when Xi became president.
New research from the Asia Society Policy Institute tracked policies in which Xi is reported by state media to have “personally” taken action.
It found that environmental protection is one of six topics in which he is often said to have directly steered policymaking.
Such policies include guidelines to build a “Beautiful China”, the creation of an environmental protection inspection team and the “three-north shelterbelt” afforestation programme.
“It’s important to know what Xi’s priorities are because the top leader wields outsized influence in the Chinese political system,” Neil Thomas, Asia Society Policy Institute fellow and report co-author, told Carbon Brief.
Local policymakers are “more likely” to invest resources in addressing policies they know have Xi’s attention, to increase their chances for promotion, he added.
What about climate and energy?
However, the research noted, climate and energy policies have not been publicised as bearing Xi’s personal touch.
“I think Xi prioritises environmental protection more than climate change because reducing pollution is an issue of social stability,” Thomas said, noting that “smoggy skies and polluted rivers” were more visible and more likely to trigger civil society pushback than gradual temperature increases.
The paper also said topics might not be linked to Xi personally when they are “too technical” or “politically sensitive”.
For example, Xi’s landmark decision for China to achieve carbon neutrality by 2060 is widely reported as having only been made after climate modelling – facilitated by former climate envoy Xie Zhenhua – showed that this goal was achievable.
Prior to this, Xi had never spoken publicly about carbon neutrality.
Prof Alex Wang, a University of California, Los Angeles professor of law not involved in the research, noted that emphasising Xi’s personal attention may signal “top” political priorities, but not necessarily Xi’s “personal interests”.
By not emphasising climate, he said, Xi may be trying to avoid “pushing the system to overprioritise climate to the exclusion of the other priorities”.
There are other ways to know where climate ranks on the policy agenda, Thomas noted:
“Climate watchers should look at what Xi says, what Xi does and what policies Xi authorises in the name of the ‘central committee’. Is Xi talking more about climate? Is Xi establishing institutions and convening meetings that focus on climate? Is climate becoming a more prominent theme in top-level documents?”

Key developments
‘Deadly’ wildfires
WINE BRAKE: France experienced its “largest wildfire in decades”, which scorched more than 16,000 hectares in the country’s southern Aude region, the Associated Press said. “Gusting winds” fanned the flames, Reuters reported, but local winemakers and mayors also “blam[ed] the loss of vineyards”, which can act as a “natural, moisture-filled brake against wildfires”, for the fire’s rapid spread. It added that thousands of hectares of vineyards were removed in Aude over the past year. Meanwhile, thousands of people were evacuated from “deadly” wildfires in Spain, the Guardian said, with blazes ongoing in other parts of Europe.
MAJOR FIRES: Canada is experiencing its second-worst wildfire season on record, CBC News reported. More than 7.3m hectares burned in 2025, “more than double the 10-year average for this time of year”, the broadcaster said. The past three fire seasons were “among the 10 worst on record”, CBC News added. Dr Mike Flannigan from Thompson Rivers University told the Guardian: “This is our new reality…The warmer it gets, the more fires we see.” Elsewhere, the UK is experiencing a record year for wildfires, with more than 40,000 hectares of land burned so far in 2025, according to Carbon Brief.

WESTERN US: The US state of Colorado has recorded one of its largest wildfires in history in recent days, the Guardian said. The fire “charred” more than 43,300 hectares of land and led to the temporary evacuation of 179 inmates from a prison, the newspaper said. In California, a fire broke out “during a heatwave” and burned more than 2,000 hectares before it was contained, the Los Angeles Times reported. BBC News noted: “Wildfires have become more frequent in California, with experts citing climate change as a key factor. Hotter, drier conditions have made fire seasons longer and more destructive.”
FIRE FUNDING: “Worsening fires” in the Brazilian Amazon threaten new rainforest funding proposals due to be announced at the COP30 climate summit later this year, experts told Climate Home News. The new initiatives include the Tropical Forests Forever Facility, which the outlet said “aims to generate a flow of international investment to pay countries annually in proportion to their preserved tropical forests”. The outlet added: “If fires in the Amazon continue to worsen in the years to come, eligibility for funding could be jeopardised, Brazil’s environment ministry acknowledged.”
Farming impacts
OUT OF ORBIT: US president Donald Trump moved to “shut down” two space missions which monitor carbon dioxide and plant health, the Associated Press reported. Ending these NASA missions would “potentially shu[t] off an important source of data for scientists, policymakers and farmers”, the outlet said. Dr David Crisp, a retired NASA scientist, said the missions can detect the “glow” of plant growth, which the outlet noted “helps monitor drought and predict food shortages that can lead to civil unrest and famine”.
FARM EXTREMES: Elsewhere, Reuters said that some farmers are considering “abandoning” a “drought-hit” agricultural area in Hungary as “climate change cuts crop yields and reduces groundwater levels”. Scientists warned that rising temperatures and low rainfall threaten the region’s “agricultural viability”, the newswire added. Meanwhile, the Premium Times in Nigeria said that some farmers are “harvest[ing] crops prematurely” due to flooding fears. A community in the south-eastern state of Imo “has endured recurrent floods, which wash away crops and incomes alike” over the past decade, the newspaper noted.
SECURITY RISKS: Food supply chains in the UK face “escalating threats from climate impacts and the migration they are triggering”, according to a report covered by Business Green. The outlet said that £3bn worth of UK food imports originated from the 20 countries “with the highest numbers of climate-driven displacements” in 2024, based on analysis from the Energy and Climate Intelligence Unit. The analysis highlighted that “climate impacts on food imports pose a threat to UK food security”. Elsewhere, an opinion piece in Dialogue Earth explored how the “role of gender equity in food security remains critically unaddressed”.

Fossil-fuelled bird decline
This week, Carbon Brief covers a new study tracing the impact of fossil-fuelled climate change on tropical birds.
Over the past few years, biologists have recorded sharp declines in bird numbers across tropical rainforests – even in areas untouched by humans – with the cause remaining a mystery.
A new study published this week in Nature Ecology and Evolution could help to shed light on this alarming phenomenon.
The research combined ecological and climate attribution techniques for the first time to trace the fingerprint of fossil-fuelled climate change on declining bird populations.
It found that an increase in heat extremes driven by climate change has caused tropical bird populations to decline by 25-38% in the period 1950-2020, when compared to a world without warming.
In their paper, the authors noted that birds in the tropics could be living close to their “thermal limits”.
Study lead author Dr Maximilian Kotz, a climate scientist at the Barcelona Supercomputing Center in Spain, explained to Carbon Brief:
“High temperature extremes can induce direct mortality in bird populations due to hyperthermia and dehydration. Even when they don’t [kill birds immediately], there’s evidence that this can then affect body condition which, in turn, affects breeding behaviour and success.”
Conservation implications
The findings have “potential ramifications” for commonly proposed conservation strategies, such as increasing the amount of land in the tropics that is protected for nature, the authors said. In their paper, they continued:
“While we do not disagree that these strategies are necessary for abating tropical habitat loss…our research shows there is now an additional urgent need to investigate strategies that can allow for the persistence of tropical species that are vulnerable to heat extremes.”
In some parts of the world, scientists and conservationists are looking into how to protect wildlife from more intense and frequent climate extremes, Kotz said.
He referenced one project in Australia which is working to protect threatened wildlife following periods of extreme heat, drought and bushfires.
Prof Alex Pigot, a biodiversity scientist at University College London (UCL), who was not involved in the research, said the findings reinforced the need to systematically monitor the impact of extreme weather on wildlife. He told Carbon Brief:
“We urgently need to develop early warning systems to be able to anticipate in advance where and when extreme heatwaves and droughts are likely to impact populations – and also rapidly scale up our monitoring of species and ecosystems so that we can reliably detect these effects.”
There is further coverage of this research on Carbon Brief’s website.
News and views
EMPTY CALI FUND: A major voluntary fund for biodiversity remains empty more than five months after its launch, Carbon Brief revealed. The Cali Fund, agreed at the COP16 biodiversity negotiations last year, was set up for companies who rely on nature’s resources to share some of their earnings with the countries where many of these resources originate. Big pharmaceutical companies did not take up on opportunities to commit to contributing to the fund or be involved in its launch in February 2025, emails released to Carbon Brief showed. Just one US biotechnology firm has pledged to contribute to the fund in the future.
LOSING HOPE: Western Australia’s Ningaloo reef – long considered a “hope spot” among the country’s coral reefs for evading major bleaching events – is facing its “worst-ever coral bleaching”, Australia’s ABC News reported. The ocean around Ningaloo has been “abnormally” warm since December, resulting in “unprecedented” bleaching and mortality, a research scientist told the outlet. According to marine ecologist Dr Damian Thomson, “up to 50% of the examined coral was dead in May”, the Sydney Morning Herald said. Thomson told the newspaper: “You realise your children are probably never going to see Ningaloo the way you saw it.”
‘DEVASTATION BILL’: Brazil’s president, Luiz Inácio Lula da Silva, signed a “contentious” environmental bill into law, but “partially vetoed” some of the widely criticised elements, the Financial Times reported. Critics, who dubbed it the “devastation bill”, said it “risked fuelling deforestation and would harm Brazil’s ecological credentials” just months before hosting the COP30 climate summit. The newspaper said: “The leftist leader struck down or altered 63 of 400 provisions in the legislation, which was designed to speed up and modernise environmental licensing for new business and infrastructure developments.” The vetoes need to be approved by congress, “where Lula lacks a majority”, the newspaper noted.
RAINFOREST DRILLING: The EU has advised the Democratic Republic of the Congo (DRC) against allowing oil drilling in a vast stretch of rainforest and peatland that was jointly designated a “green corridor” earlier this year, Climate Home News reported. In May, the DRC announced that it planned to open the conservation area for drilling, the publication said. A spokesperson for the European Commission told Climate Home News that the bloc “fully acknowledges and respects the DRC’s sovereign right to utilise its diverse resources for economic development”, but that it “highlights the fact that green alternatives have facilitated the protection of certain areas”.
NEW PLAN FOR WETLANDS: During the 15th meeting of the Ramsar Convention on Wetlands, held in Zimbabwe from 23 to 31 July, countries agreed on the adoption of a new 10-year strategic plan for conserving and sustainably using the world’s wetlands. Down to Earth reported that 13 resolutions were adopted, including “enhancing monitoring and reporting, capacity building and mobilisation of resources”. During the talks, Zimbabwe’s environment minister announced plans to restore 250,000 hectares of degraded wetlands by 2030 and Saudi Arabia entered the Convention on Wetlands. Panamá will host the next COP on wetlands in July 2028.
MEAT MADNESS: DeSmog covered the details of a 2021 public relations document that revealed how the meat industry is trying to “make beef seem climate-friendly”. The industry “may have enlisted environmental groups to persuade people to ‘feel better’ about eating beef”, the outlet said, based on this document. The strategy was created by a communications agency, MHP Group, and addressed to the Global Roundtable for Sustainable Beef. One of the key messages of the plan was to communicate the “growing momentum in the beef industry to protect and nurture the Earth’s natural resources”. MHP Group did not respond to a request for comment, according to DeSmog.

CCL submits a formal comment on EPA’s proposed endangerment finding rollback
By Dana Nuccitelli, CCL Research Manager
On July 29, the EPA proposed to rescind its 2009 endangerment finding that forms the basis of all federal climate pollution regulations.
Without the endangerment finding, the EPA may not be allowed or able to regulate greenhouse gas pollution from sources like power plants or vehicle tailpipes, as they have done for years. News coverage has framed this as a “radical transformation” and a “bid to scrap almost all pollution regulations,” so it has appropriately alarmed many folks in the climate and environment space.
At CCL, we focus our efforts on working with Congress to implement durable climate policies, and so we don’t normally take actions on issues like this that relate to federal agencies or the courts. Other organizations focus their efforts on those branches of the government and are better equipped to spearhead this type of moment, and we appreciate those allies.
But in this case, we did see an opportunity for CCL’s voice — and our focus on Congress — to play a role here. We decided to submit a formal comment on this EPA action for two reasons.
First, this decision could have an immense impact by eliminating every federal regulation of climate pollutants in a worst case scenario. Second, this move relates to our work because the EPA is misinterpreting the text and intent of laws passed by Congress. Our representatives have done their jobs by passing legislation over the past many decades that supports and further codifies the EPA’s mandate to regulate climate pollution. That includes the Clean Air Act, and more recently, the Inflation Reduction Act. We at CCL wanted to support our members of Congress by making these points in a formal comment.
There has been a tremendous public response to this action. In just over one week, the EPA already received over 44,000 public comments on its decision, and the public comment period will remain open for another five weeks, until September 15.
To understand more about the details and potential outcomes of the EPA’s actions, read my article on the subject at Yale Climate Connections, our discussion on CCL Community, and CCL’s formal comment, which represents our entire organization. As our comment concludes,
“In its justifications for rescinding the 2009 endangerment finding, the Reconsideration has misinterpreted the text of the Clean Air Act, Congress’ decadeslong support for the EPA’s mandate to regulate greenhouse gas emissions from motor vehicles and other major sources, and the vast body of peer-reviewed climate science research that documents the increasingly dangerous threats that those emissions pose to Americans’ health and welfare. Because the bases of these justifications are fundamentally flawed, CCL urges the EPA to withdraw its ill-conceived Reconsideration of the 2009 endangerment finding. The EPA has both the authority and the responsibility to act. Americans cannot afford a retreat from science, law, and common sense in the face of a rapidly accelerating climate crisis.”
After the EPA responds to the public comment record and finalizes its decision, this issue will ultimately be decided by the Supreme Court several years from now.
In the meantime, CCL will continue to focus our efforts on areas where we can make the biggest difference in preserving a livable climate. Right now, that involves contacting our members of Congress to urge them to fully fund key climate and energy programs and protect critical work at the National Oceanic and Atmospheric Administration (NOAA), National Aeronautics and Space Administration (NASA), and Department of Energy. We’ve set an ambitious goal of sending 10,000 messages to our members of Congress, so let’s all do what CCL does best and make our voices heard on this critical issue.
This action by the EPA also reminds us that federal regulations are fragile. They tend to change with each new administration coming into the White House. Legislation passed by Congress – especially when done on a bipartisan basis – is much more durable. That’s why CCL’s work, as one of very few organizations engaging in nonpartisan advocacy for long-lasting climate legislation, is so critical.
That’s especially true right now when we’re seeing the Trump administration slam shut every executive branch door to addressing climate change. We need Congress to step up now more than ever to implement durable solutions like funding key climate and energy programs, negotiating a new bipartisan comprehensive permitting reform bill, implementing healthy forest solutions like the Fix Our Forests Act, and advancing conversations about policies to put a price on carbon pollution. Those are the kinds of effective, durable, bipartisan climate solutions that CCL is uniquely poised to help become law and make a real difference in preserving a livable climate.
For other examples of how CCL is using our grassroots power to help ensure that Congress stays effective on climate in this political landscape, see our full “Holding the Line on Climate” blog series.
