China’s energy sector carbon dioxide (CO2) emissions increased 5.2% in 2023, meaning a record fall of 4-6% is needed by 2025 to meet the government’s “carbon intensity” target.
The new analysis for Carbon Brief, based on official figures and commercial data, shows rapid electricity demand growth and weak rains boosted demand for coal power in 2023, while the rebound from zero-Covid boosted demand for oil.
Other key findings from the analysis include:
- China’s CO2 emissions have now increased by 12% between 2020 and 2023, after a highly energy- and carbon-intensive response to the Covid-19 pandemic.
- This means CO2 emissions would need to fall by 4-6% by 2025, in order to meet the target of cutting China’s carbon intensity – its CO2 emissions per unit of economic output – by 18% during the 14th five-year plan period.
- China is also at risk of missing all of its other key climate targets for 2025, including pledges to “strictly limit” coal demand growth and “strictly control” new coal power capacity, as well as targets for energy intensity, the share of low-carbon energy in overall demand and the share of renewables in energy demand growth.
- Government pressure to hit the targets, most of which are in China’s updated international climate pledge under the Paris Agreement, makes it more likely that China’s CO2 emissions will peak before 2025 – far earlier than its target of peaking “before 2030”.
The deadline for peaking CO2 emissions has led officials and industries to pursue rapid emissions growth and carbon-intensive projects, while a window to do so remains open.
The government recently recognised and responded to the gap to meeting its targets, by calling for stronger controls on such projects, as well as faster renewables deployment.
Most of China’s climate targets can be met if the acceleration of clean energy deployment during 2023 is maintained – and if energy demand growth returns to pre-Covid levels.
- China’s CO2 emissions continued to increase in 2023
- China is off track to all of its 2025 climate targets
- Official energy data is over-reporting coal consumption growth
- Government response
- The clean energy boom can allow most targets to be met
- About the data
China’s CO2 emissions continued to increase in 2023
According to preliminary official data, China’s total energy consumption increased by 5.7% in 2023, the first time since at least 2005 that energy demand has grown faster than GDP.
With coal consumption growing by 4.4%, our analysis shows CO2 emissions increasing by 5.2% – at the same rate as GDP – highlighting energy-intensive recent growth patterns.
China’s economic growth during and after the Covid-19 pandemic has been highly energy- and carbon-intensive. CO2 emissions grew at an average of 3.8% per year in 2021-23, up from 0.9% a year in 2016-20, while GDP growth slowed from an average of 5.7% to 5.4%.
Another year of rapidly rising emissions in 2023 leaves China way off track against its target of cutting carbon intensity by 18% during the 14th five-year plan (2021-25).
As a result, CO2 emissions would now need to fall by 4-6% by 2025 to hit the goal. This is illustrated in the figure below, showing historical emissions (black line) and the reductions needed by 2025 to hit the carbon intensity target, depending on the rate of GDP growth.
Even if China’s GDP growth is high and averages 6% per year in 2024-25, the intensity target requires CO2 emissions to fall by 4%.
The main drivers of the emissions increase in 2023 were coal-fired power and oil consumption, which increased by 6% and 8%, respectively.
A major reason for the growth in power generation from coal was that hydropower operating rates reached the lowest level in more than two decades due to a series of droughts. These operating rates are likely to recover towards average levels in 2024.
The increase in oil consumption represents a rebound from the slow demand growth during zero-Covid and an outright drop in 2022. Gas consumption rebounded as prices came down from 2022 highs, while still remaining elevated.
The clean energy manufacturing boom also has a role in driving emissions, due to energy-intensive processes involved in the production of solar PV and batteries, in particular.
Approximately one percentage-point of CO2 emission growth can be attributed to these sectors, based on output data and emission intensities estimated for solar PV, electric vehicles and batteries.
This means that, without the clean technology manufacturing boom, China’s CO2 emissions would have grown by around 4.2%, instead of the 5.2% estimated in our analysis.
Nevertheless, the increase in manufacturing will result in a significant reduction in emissions in net terms, once the products are in use. About half of this reduction will be realised outside of China, as the products are exported.
China is off track to all of its 2025 climate targets
China’s climate pledge under the Paris Agreement (nationally determined contribution, NDC) was updated in 2021, following commitments made by President Xi Jinping earlier that year and incorporating targets set under the 14th five-year plan.
The updated NDC makes commitments to strictly limit coal consumption growth; strictly control new coal power; reduce energy and carbon intensity by 2025; and increase the share of non-fossil energy sources to 25% by 2030.
In addition, the country’s five-year plans set targets of increasing the share of non-fossil energy sources to 20% by 2025 and deriving more than 50% of the increase in energy use from 2020 to 2025 overall from renewable sources.
All of these targets are severely off track after 2023.
The table below lists the various climate- and energy-related targets, the progress seen from 2020-23 and what would be needed during 2024-25 to achieve each of the goals. (See below for further details on each indicator and what is needed by 2025.)
China’s 2025 climate commitments and targets in the energy sector
| Indicator | Target | Progress in 2020-23 | Change needed in 2024-25 |
| Carbon intensity | -18% | -4.6% (-1.5%/year) | -7%/year; reduce emissions in absolute terms |
| Energy intensity | -13.5% | -2% (-0.6%/year) | -6%/year; reduce energy use in absolute terms |
| Coal consumption growth | “strictly limit” | Annual growth increased eightfold from 0.5% in 2016-20 to 3.8% | Negative growth to limit increase to the same rate as previous five-year period |
| New coal power projects | “strictly control” | Permits increased fourfold, from 25GW per year in 2016-20 to 110GW per year | Restrict new permits and review permits already granted |
| Non-fossil share of energy overall | Increase by 4.1 percentage points | Increased by 1.8 percentage points (0.6 points per year) | Rate of increase has to double to 1.2 points per year |
| Share of energy consumption growth met by renewables | Above 50% | 30%, down from 42% in 2016-20 | Renewable energy growth needs to double and energy consumption growth needs to slow to pre-Covid rate; total consumption of fossil fuels needs to fall.Renewable energy growth needs to double and energy consumption growth needs to slow to pre-Covid rate; total consumption of fossil fuels needs to fall. |
The centrepiece of China’s 2020 and 2025 climate commitments has been reducing carbon intensity, or CO2 emissions from energy use per unit of GDP.
The country’s carbon intensity reportedly fell 48% from 2005 to 2020. China committed to an 18% fall from 2020 to 2025 – and to reducing carbon intensity by more than 65% from 2005 levels by 2030, which requires a further reduction of at least 17% from 2025 to 2030.
However, as of the end of 2023, China’s carbon intensity has only fallen 5% in the 14th five-year plan period, lagging far behind the target of 18% from 2020 to 2025. If this target is to be met, CO2 emissions will have to come down in absolute terms from 2023 to 2025.
The figure below shows how China overachieved against its carbon intensity target for 2015-2020 but is veering increasingly off track against the goal for 2020-2025.
China’s energy intensity increased by 0.5% in 2023, the first annual rise since at least 2005. From 2020 to 2023, energy intensity only fell 2%.
The figure below shows that China narrowly missed its energy intensity target during the 13th five-year plan period, spanning 2016 to 2020, as progress halted in 2020. The country is now far off track for its 14th five-year plan target.
Indeed, to meet the target of a 13.5% reduction over 2020-25 – given the lack of progress as of the end of 2023 – energy consumption would have to fall in absolute terms over the next two years, while the rate of GDP growth is maintained or accelerated. This makes the goal all but unachievable.
The share of China’s energy demand met by non-fossil sources has increased by 1.8 percentage points from 2020 to 2023, against a target of 4.1 points by 2025.
This is shown in the figure below, illustrating the targeted 15% share for non-fossil energy by 2020 and 20% by 2025, as well as progress to date.
Meeting the 2025 target would mean that the rate of increase needs to double for the next two years. Moreover, if energy demand growth continues at the exceptionally high rate of 2020 to 2023, then energy production from non-fossil sources would need to grow at 11.3% per year to meet the target, up from 8.5% in the past three years.
Alternatively, the growth of renewables and nuclear could be maintained – but energy consumption growth would have to slow down to its pre-Covid average.
Only 30% of energy consumption growth has been met by renewable energy in 2020 to 2023, against a target of more than 50% during 2020-25.
This is illustrated in the figure below, showing contributions to annual energy demand growth from fossil fuels (grey bars), nuclear (blue) and renewables (red).
The 50% target is now highly unlikely to be met without a slowdown in energy consumption growth. Without a slowdown, renewables would have to grow by 20% per year to meet the target, up from 8.9% in the past three years.
Both growth in coal consumption and new coal power projects accelerated sharply in 2021-23, despite Xi’s pledges to “strictly control” them.
This is illustrated in the figure below, with annual coal consumption growth on the left and the amount of new coal capacity added each year on the right.
Indeed, the average growth rate of coal consumption increased 8-fold from 0.5% per year in 2016-20 to 3.8% per year in 2021-23.
Similarly, new coal power approvals increased fourfold in 2022-23, compared with the five years before the “strictly control” pledge, based on analysis of Global Energy Monitor data.
Since the beginning of 2022, a total of 218 gigawatts (GW) of new coal power plants have been permitted. By the end of 2023, some 89GW of this capacity had already started construction, while 128GW had yet to break ground.
Furthermore, the government’s official policy has shifted to strongly encouraging new coal power. An assessment of the projects permitted in 2022-23 shows that requirements, set for approving new coal power plants in August 2021, have not been enforced.
Statements from developers and government officials – see below – confirm that the 14th five-year plan period until 2025 is being seen as a “window of opportunity” for new coal power plants, rather than a period when new projects are strictly controlled.
This is causing a rush to secure permits for new projects. China Shenhua called the period until 2025 “an opportune time for thermal power construction”. The provincial state-owned enterprise supervisor boasts of Inner Mongolia Energy Group “achieving a flying start” to 2023 and “seizing the policy window” for coal power projects.
The Zhejiang province energy regulator emphasised the importance of seizing the time window for thermal power construction during the 14th five-year period.
Power China called for joint efforts with local government officials to exploit the coal power development window effectively, citing a plan known as “three times 80GW”. This refers to a proposal promoted by the thermal power construction industry to permit and commission 80GW of coal power plants each year, from 2022 to 2024.
The meaning of the pledges to “strictly control” growth in coal consumption and new coal power projects lacks a precise definition. However, a sharp acceleration of coal consumption growth and coal power plant approvals, along with active government promotion of new projects, is hard to reconcile with the pledge to exert strict control.
By this logic, meeting the pledge on coal consumption growth would require, at the very least, reducing coal use from 2023 to 2025 to bring the growth rate during the 2021 to 2025 period closer to the rate during the preceding five-year period.
Similarly, meeting the commitment to control new coal power projects would require enforcing existing policy to limit new schemes, restricting new permits and reviewing permits already granted, to limit the acceleration compared with the preceding five-year period.
Official energy data is over-reporting coal consumption growth
In 2022, government policies seeking to increase coal mine output and push down coal prices led to a sharp deterioration in the quality and calorific value of coal produced.
This fall in quality meant that the weight of coal being consumed increased by far more than the amount of energy supplied or CO2 emitted from that coal.
China’s official statistics failed to capture the change and consequently over-reported the growth in coal consumption and under-reported the improvement in CO2 intensity in 2022. This 2022 data could be expected to be revised once more complete energy statistics are released later.
Unlike in 2022, the officially-reported coal consumption growth rate for 2023 is more closely aligned with growth in coal power generation and output in key heavy industry sectors. The data indicates that coal use grew 4.4% in 2023, while power generation from coal rose 6%.
However, the conclusion that CO2 emissions need to fall from 2023 to 2025 to meet the carbon intensity target holds, even if a correction to 2022 data is made.
Calculating with current official data, CO2 emissions need to fall by 3.8-6.5% in the next two years, depending on the growth rate of GDP.
Based on my previous estimate that the growth in CO2 emissions in 2022 was inflated by 2.3 percentage points, a correction for 2022 would put the required reduction at 1.6-4.3%.
Government response
Energy intensity and carbon intensity reduction are among the 20 “main indicators” specified in China’s overarching five-year plan for 2021-25.
The mid-term evaluation of progress, published by China’s top economic planner the national development and reform commission (NDRC) in December 2023, identified these indicators as two of the four that were off track, along with a key air quality target.
(Air pollution concentrations also rose in 2023 due to increased industrial and transportation emissions, along with unfavourable weather conditions.)
In late 2023, the NDRC reprimanded the provinces of Hubei, Shaanxi, Gansu, Qinghai, Zhejiang, Anhui, Guangdong and Chongqing for lagging behind on the targets to control energy intensity and total energy consumption.
Zhou Dadi, a member of the national climate change expert advisory committee, pointed to the weak growth in service industries as the reason for the lack of progress on the intensity targets.
Service sectors have relatively low energy demand and carbon emissions relative to economic output, so the decline in their share of economic activity tends to increase the energy and carbon intensity of the economy.
The NDRC’s evaluation report also identified measures to achieve the targets, including improving policies to control energy use and carbon emissions, curbing the initiation of projects with high energy consumption and high emissions, strictly limiting total coal consumption, promoting a shift to cleaner industry and transportation, promoting energy conservation and, importantly, accelerating the deployment of renewable energy.
The clean energy boom can allow most targets to be met
While China fell severely behind on its 2025 climate targets for the energy sector, the past two years saw a veritable boom in clean energy installations – particularly solar power.
This boom puts most of the targets still in reach, especially if energy demand growth returns to the pre-Covid rates.
My earlier analysis showed that China’s CO2 emissions could fall this year and then stabilise, if additions of low-carbon power generation continue at 2023 rates and electricity demand returns to trend.
Under this projection, CO2 emissions fall by approximately 1.5% from 2023 to 2025. Therefore, achieving the 4-6% reduction in CO2 emissions needed to meet the CO2 intensity target from 2023 to 2025 would require further acceleration in clean energy deployment, or a sharp slowdown in energy demand growth.
The increase in the share of non-fossil energy should be possible to achieve given the sharp increase in solar and wind installations in 2023. To start with, slow progress was partially caused by the record-low hydropower operating rates in 2023, linked to record droughts.
Even if energy demand continued to grow at the 2020-23 rate, continued low-carbon energy additions at the 2023 level should suffice to raise the share of non-fossil energy to 21%, comfortably ahead of the target.
The target of renewable energy contributing half of the growth in total energy demand is significantly more challenging.
If energy consumption growth rate slows down to its pre-Covid average and clean energy capacity additions continue at the 2023 rate, enabling the growth rate of renewable energy production to almost double to 16%, then the target would likely be reached.
This would also mean a reduction in the total consumption of fossil fuels and a reduction in energy sector CO2 emissions. This scenario would arguably also meet the commitment to “strictly limit the growth in coal consumption”.
Meeting the pledge to “strictly control” new coal power projects would mean thoroughly assessing the justification for permits granted in the past two years and restricting the issuance of new permits.
The large amount of electricity storage being deployed – especially pumped hydro, but increasingly also grid-connected batteries – reduces the need for thermal power plants.
For a significant restriction of new coal power to be possible while ensuring electricity supply security, progress would also be needed on power system reforms that increase flexibility and make more efficient use of existing capacity.
China’s clean energy boom has been happening much faster than official targets for wind and solar installations would require, driven by enthusiasm from local governments, state-owned enterprises and investors.
However, due to the rapid increase in energy consumption, meeting China’s headline climate targets now requires that the momentum of clean energy installations is maintained.
About the data
Total energy consumption and energy mix were taken from national bureau of statistics annual data. Improvements in energy intensity and carbon intensity were compiled from the bureau’s annual statistical communiques and changes in carbon emissions were calculated based on reported GDP growth and carbon intensity improvement.
Growth in total energy consumption and changes in the energy mix were taken from preliminary information released by the national bureau of statistics. Growth in CO2 emissions in 2023 was calculated using Intergovernmental Panel on Climate Change default emission factors based on changes in the consumption of coal, oil and gas.

DeBriefed 15 August 2025: Raging wildfires; Xi’s priorities; Factchecking the Trump climate report
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”.

Captured
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.

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.

New science
- Applying biochar – a type of charcoal – to soils each year over a long period of time can have “sustained benefits for crop yield and greenhouse gas mitigation”, according to a Proceedings of the National Academy of Sciences study.
- New research, published in PLOS Climate, found that nearly one-third of highly migratory fish species in the US waters of the Atlantic Ocean have “high” or “very high” vulnerability to climate change, but the majority of species have “some level of resilience and adaptability”.
- A study in Communications Earth & Environment found a “notable greening trend” in China’s wetlands over 2000-23, with an increasing amount of carbon being stored in the plants growing there.

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.
