A record surge of clean energy kept China’s carbon dioxide (CO2) emissions below the previous year’s levels in the last 10 months of 2024.

However, the new analysis for Carbon Brief, based on official figures and commercial data, shows the tail end of China’s rebound from zero-Covid in January and February, combined with abnormally high growth in energy demand, stopped CO2 emissions falling in 2024 overall.

While China’s CO2 output in 2024 grew by an estimated 0.8% year-on-year, emissions were lower than in the 12 months to February 2024.

Other key findings of the analysis include:

China’s CO2 emissions grew 0.6% year-on-year in the fourth quarter, as hopes of stimulus measures pushed up industrial coal use and oil demand.
In addition, wind and solar fell short of expected levels in the final quarter of 2024, likely as a result of being denied grid access in favour of coal power, which was flat year-on-year.
Clean-energy capacity growth will accelerate in 2025 as largescale wind, solar and nuclear projects race to finish before the 14th five-year plan period comes to an end.
Industrial electricity demand growth has slowed since summer 2024 and total energy demand growth eased in the fourth quarter of the year.
These factors would be expected to push China’s coal-power output into decline in 2025, which would have international significance for energy markets and emissions.
However, another period of industrial demand growth driven by government stimulus efforts could change this picture, particularly if the real-estate slump turns around.

As ever, the latest analysis shows that policy decisions made in 2025 will strongly affect China’s emissions trajectory in the coming years. In particular, both China’s new commitments under the Paris Agreement and the country’s next five-year plan are being prepared in 2025.In particular, both China’s new commitments under the Paris Agreement and the country’s next five-year plan are being prepared in 2025.

Emissions have plateaued since February 2024

China’s re-opening from zero-Covid began in earnest in March 2023, leading to rapid energy demand growth year-on-year until February 2024.

This resulted in a 3.8% rise in China’s CO2 emissions in the first quarter of 2024.

Emissions stabilised in March-December 2024 as clean electricity supply growth covered all of the growth in electricity demand, while emissions from cement and steel production fell due to contracting demand for construction materials. This is shown in the figure below.

Sector breakdown of coal consumption is estimated using coal consumption data from WIND Information and electricity data from the National Energy Administration.

After February 2024, oil consumption growth also stabilised. Coal use in the chemical industry and coal and gas use in other industrial sectors continued to grow, offsetting the fall in emissions from the construction materials industry.

Contributions to the emissions plateau during the final 10 months of 2024 are shown in the figure below, broken down by fuel and by sector, where data is available.

Sector breakdown of coal consumption is estimated using coal consumption data from WIND Information and electricity data from the National Energy Administration.

The growth in power generation from non-fossil sources set a new record, growing more than 500 terawatt hours (TWh) compared with 2023, which had already been a record year.

This is more than the total power generation of Germany in 2023. Solar power generation was responsible for half of the increase in clean power supply.

Emissions inched up in the fourth quarter

After rising in the first quarter of 2024, China’s CO2 emissions started to decline in March, falling 1% in the second quarter of the year and levelling off in the third quarter.

While power-sector emissions remained stable in the fourth quarter, industrial emissions outside the power sector swung into an increase. There was no reduction in power-sector emissions to offset that growth, resulting in an estimated 0.6% increase in overall emissions.

The largest factor was a rebound in oil and gas demand outside the power sector, indicated by the large bars under “All Sectors” and “Other Sectors” in the figure below.

Preliminary numbers from the National Bureau of Statistics indicate gas and oil demand rose 10% and 3% year-on-year, respectively, in the fourth quarter of 2024.

The supply of refined oil products fell 1.5%, so the increase in oil demand apparently came entirely from crude oil consumption in the chemical industry.

Steel output picked up after stimulus announcements in late September, increasing 2% in October-November and 12% in December after a 4% reduction in the year to September.

The December increase, however, came from the reversal of a sharp 15% drop in production in December 2023, which was a last-minute measure to adhere to a cap set by the government for steel production during the year. As a result, steel production in December 2024 saw a dramatic increase year-on-year, but remained below 2022 levels.

Gas consumption has been rebounding from a drop caused by spiking prices in 2022, but demand growth is expected to moderate this year.

Cement production fell 6% year-on-year in the last quarter, extending a decline that started in 2020 and that has seen China’s cement output fall by almost a quarter from its peak level, as construction volumes have fallen.

Clash between coal and clean energy

As shown in the chart above, emissions from the power sector remained flat during the fourth quarter of 2024, with a small fall from coal and a small rise from gas. However, as electricity demand growth slowed down to 3.5%, emissions would have been expected to fall.

Even as electricity demand growth slowed down in October and November, fossil-fuel generation continued to increase. This was due to a sharp drop in the utilisation of solar and wind capacity, as shown by China Electricity Council data accessed through Wind Financial Terminal.

It is normal for utilisation to vary month-to-month, especially in the case of wind power, as wind conditions vary. The fall in utilisation of solar power was, however, the largest on record and, in the case of both solar and wind, this specific drop is not readily explained by weather conditions.

Lauri Myllyvirta on Bluesky: The weather conditions for solar and wind were a bit worse than last year

If the fall in utilisation was not caused by weather, the other possible cause is an increase in curtailment, or the amount of solar and wind power supply not fed into the power grid.

However, officially reported curtailment rates only increased marginally.

The apparent increase in unreported solar and wind curtailment in November is indicative of issues likely to arise in China’s electricity market as demand for coal-fired power begins to fall.

The government has pushed electricity buyers to enter into long-term contracts with coal-power companies, which involve guaranteed sales volumes. This has been a way to shore up profitability and enable investments in new coal-power capacity.

This now appears to be coming into conflict with clean-power growth and efforts to limit emissions.

When power generation from clean sources grows faster or total power demand grows slower than expected, electricity buyers with these long-term contracts can face penalties, unless they refuse power supply from clean sources and purchase from coal-power generators instead.

This conflict is accentuated when a lot of new coal-power capacity enters into the market. The new units have internal production targets and, at least in some cases, power purchase agreements signed in advance, making them unwilling to reduce output, even if there is no space in the grid.

It is notable that the first time that renewable energy curtailment became a major issue in China was around 2015, when demand for power generation from coal was falling.

Statistical analysis also reveals that solar and wind capacity utilisation tends to fall when coal-power capacity utilisation falls as well – the opposite of what should be expected. In a well-functioning market, coal-power utilisation should fall when more clean power is available.

A statistic a l model predicting solar and wind power utilisation by province, using daily meteorological data, failed to predict the drop in utilisation in October and November, indicating that weather conditions were not the main reason for the reduction.

If power demand growth slows down in 2025 and the expected record clean-energy additions are realised (see below), the conflict between coal and clean power could worsen. Demand for coal-fired power would be likely to fall, even as the coal industry expects rapid growth.

It would only be possible to ease this conflict by relaxing the government’s targets for long-term power contracts and accepting a fall in the utilisation of coal-power capacity.

Did emissions peak in 2024?

A year ago, an earlier iteration of this analysis predicted that China’s emissions would begin to fall in March 2024 and then continue to decline, leading to a 2% reduction in the full year of 2024.

This was based on three assumptions:

Clean-energy additions would continue;
Hydropower generation would recover to historical average levels;
Energy consumption growth would slow down, after abnormally rapid growth in 2020-2023, during and after zero-Covid.

Taking each of those assumptions in turn, clean-energy additions not just continued but accelerated further, with 2024 poised to see a new record for the amount of solar and wind capacity added. Hydropower also recovered, although not all the way to historical averages.

The clean-energy additions, shown by the columns in the figure below, reached a scale where they would be sufficient to cover all energy demand growth at historical pre-Covid levels (grey line).

Indeed, the growth in clean-energy supply in 2024 far exceeded the growth in total energy demand recorded in any year from 2015 to 2020. However, energy demand growth in 2023-2024 was above historical norms, increasing significantly faster than in the years before Covid, even as GDP growth rates slowed down, due to high reliance on energy intensive industries to drive growth.

Non-fossil electricity supply from Ember yearly electricity data, except 2024 data from CREA monthly China snapshot. Electricity generation is converted into primary energy following the “coal power equivalent” methodology used in China.

Specifically, China’s power demand grew at 6.8% in 2024 while GDP expanded 5%. In contrast, last year’s analysis had assumed that power demand and GDP growth rates would converge after the zero-Covid period and its immediate aftermath were over.

This discrepancy was enough to throw off the projection for 2024. With energy demand growth far in excess of what had been assumed, even the massive clean-energy additions seen in 2024 were only enough to stabilise emissions, rather than to reduce them.

This means that while China’s CO2 emissions have been stable since March, it is still likely that they will post a small increase of around 0.8% for the full year, as January-February had rapid growth due to the rebound from zero-Covid.

As a result, the calendar year of 2023 did not become the peak year for China’s CO2 output, because emissions still inched up, according to current estimates.

From one perspective, stabilising emissions despite the rapid growth in energy demand is a major achievement. From another perspective, it is important for China’s emissions to begin to fall in absolute terms, if global climate goals are to remain within reach.

Even larger clean energy additions likely in 2025

After the enormous jump in China’s clean-energy installations in 2023 – particularly solar – even the most optimistic predictions did not expect a further increase in 2024.

Yet solar and wind capacity additions in China increased by 28% and 5% year-on-year in 2024, respectively, with 277GW of solar and 79GW of wind connected to the grid.

This year is likely to set another record, as key largescale solar, wind and nuclear projects race to complete during the 14th five-year plan period ending in 2025. State-owned enterprises, local governments and other actors have set targets that they will be striving to achieve.

Solar-power capacity additions are expected to stay at the record levels seen in 2024, with approximately 265GW added to the grid, according to forecasts from TrendForce New Energy Research Center.

Wind power is poised for a new record of 110-120GW of capacity added in 2025, according to China International Capital Corporation. Of this, 14-17GW is expected to be offshore wind power, up from 7GW in 2024.

After two slow years, China’s nuclear power capacity is expected to see a significant increase, rising to 65GW by the end of 2025, from 61GW today.

Some 3GW was added right at the end of 2024, starting to contribute to non-fossil power supply in 2025. In total, after a record number of new reactor projects was permitted in 2023 and 2024, China currently has 55GW approved or under construction, suggesting an average of more than 10GW of reactor start-ups per year over the next five years.

In addition, China had at least 14GW of conventional hydropower under construction at the end of 2024, based on Global Energy Monitor data on capacity under construction in April 2024 and subtracting capacity that was already commissioned last year.

Taken together, the new solar, wind, hydro and nuclear capacity that is likely to be connected to China’s grid in 2025 can be expected to generate more than 600TWh per year of electricity, up from the 500TWh of new clean electricity generation added in 2024, as shown in the figure below.

Source: Calculated based on changes in year-end capacity and average capacity utilisation for each technology from China Electricity Council data accessed through the Wind Financial Terminal.

However, as noted above, new clean-power capacity will only result in lower coal-fired generation and CO2 emissions if its output is integrated into the electricity system without a major increase in curtailment.

Aiming to avoid that outcome, in early January 2025, China’s top economic planner, the National Development and Reform Commission (NDRC), published a new power system action plan that aims to integrate more than 200GW of new wind and solar onto the grid per year in 2025-27.

While this target is below the record-breaking clean-energy additions seen in recent years, it still indicates that there is central government support for similarly rapid growth in the next few years.

In December 2024, top economic policymakers called for accelerating the construction of very largescale clean-energy “bases” in western China and introduced a new theme of creating zero-carbon industrial parks. As industrial parks are responsible for 30% of China’s CO2 emissions, this policy could also drive significant investment in clean energy.

Energy demand outlook

Whether China’s emissions remain stable or begin to fall, cementing an emissions peak, remains a race between clean-energy additions and energy demand growth.

The big question is whether the recent trend of exceptionally rapid energy demand growth will continue, or whether it will unwind, resulting in a period of demand growing slower than GDP.

The previous periods of rapid energy and power demand growth in relation to GDP, around 2004 and 2010, were followed by periods of slower demand growth. In particular, around 2015, energy demand growth slowed down markedly and China’ emissions plateaued for several years.

There are signs of a repeat of this pattern in China’s recent energy demand data.

Specifically, industrial power demand rose sharply in 2023 and 2024, but exhibited a clear slowdown in the second half of 2024, as shown in the figure below (top left).

This was masked by a rebound in service and residential sector electricity consumption. Residential demand merely caught up to the pre-Covid trendline and service sector demand remains below it, reflecting the Covid-era distortion to the structure of the economy.

China’s electricity consumption growth by sector, terawatt-hours per month. Source: National Energy Administration monthly data releases.

The recent rapid energy demand growth has been driven by an economic strategy that heavily favours energy-intensive manufacturing.

This approach has likely reached its limits as China’s manufacturing expansion has led to a supply glut, falling prices for industrial products and falling profits.

Now, the government is aiming to speed up economic growth by stimulating household consumption, a much less energy-intensive part of the economy than manufacturing, and by “halting the decline and stabilising” the real-estate sector.

However, delivering this outcome is far from trivial. The 2022 economic work conference – where annual departmental priorities are set – had also said that the recovery from zero-Covid should be consumption-led, but this vision failed to materialise.

The 2024 conference reduced the emphasis on “high-quality growth”, a concept that discourages growth driven by “low-quality” construction projects. In Communist party jargon, it said that “the relationship between improving the quality and growing the total output must be well coordinated”. This was a downgrade from 2023 when “high-quality growth” was described as a “hard truth”.

What next for energy and emissions in China?

Clean-energy additions will accelerate even further this year, from the record levels of 2024. At the same time, industrial power demand growth has slowed significantly since the summer.

These two trends suggest there is likely to be a fall in power-sector emissions this year. However, this drop in CO2 could still be outweighed by government stimulus efforts leading to another period of rapid growth in heavy industry, especially if construction volumes rebound.

If construction activity makes a strong comeback, this could drive further increases in emissions. The coal industry is bullish, with the China Coal Transportation and Distribution Association projecting a 1% increase in coal consumption in 2025.

The China Coal Industry Association projects a 4.5% increase in power generation from coal and gas. It believes that the stimulus policies to expand investment and stabilise the real-estate market will lead to increases in output in steel, cement and other major coal-consuming industries.

However, even if policymakers did pursue construction stimulus, a key question is how much of an effect it will have – and how fast.

Regardless of industry association hopes, the government’s stimulus announcements, so far, have not reversed market expectations of falling steel demand.

The local governments that are expected to deliver the stimulus are likely to struggle to fund a major increase in spending – and there is much less need for new infrastructure than during previous stimulus cycles.

If the government is successful in reviving household consumption as a source of growth – which is far less energy intensive – then energy demand growth could normalise to levels where clean energy can easily meet all of the growth. If so, emissions would begin to fall in a sustained way.

Beyond 2025, China’s energy and emissions trends are harder to pin down. For example, the rate of clean-energy additions after this year is more uncertain, despite recent positive signals.

China’s new Paris commitments are due to be published this year, containing targets for 2030 and 2035. In addition, the 15th five-year plan, covering 2026-2030, will be prepared this year and released in early 2026. As such, policy decisions made in 2025 will strongly affect China’s emissions trajectory not only this year, but for many years into the future.

About the data

Data for the analysis was compiled from the National Bureau of Statistics of China, National Energy Administration of China, China Electricity Council and China Customs official data releases, and from WIND Information, an industry data provider.

Wind and solar output, and thermal power breakdown by fuel, was calculated by multiplying power generating capacity at the end of each month by monthly utilisation, using data reported by China Electricity Council through Wind Financial Terminal.

Total generation from thermal power and generation from hydropower and nuclear power was taken from National Bureau of Statistics monthly releases.

Monthly utilisation data was not available for biomass, so the annual average of 52% for 2023 was applied. Power sector coal consumption was estimated based on power generation from coal and the average heat rate of coal-fired power plants during each month, to avoid the issue with official coal consumption numbers affecting recent data.

When data was available from multiple sources, different sources were cross-referenced and official sources used when possible, adjusting total consumption to match the consumption growth and changes in the energy mix reported by the National Bureau of Statistics for the first quarter, the first half and the first three quarters of the year, as well as for the full year. The effect of the adjustments is less than 0.4% for total annual emissions, with unadjusted numbers showing smaller in emissions in the third quarter.

CO2 emissions estimates are based on National Bureau of Statistics default calorific values of fuels and emissions factors from China’s latest national greenhouse gas emissions inventory, for the year 2018. Cement CO2 emissions factor is based on annual estimates up to 2023.

For oil consumption, apparent consumption is calculated from refinery throughput, with net exports of oil products subtracted.

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

Spotlight

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.”

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.

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.
