China’s carbon dioxide (CO2) emissions stayed at, or just below, last year’s levels in the third quarter of 2024, after a fall in the second quarter.
The new analysis for Carbon Brief, based on official figures and commercial data, leaves open the possibility that China’s emissions could fall this year.
However, recent record-high temperatures caused emissions to go up in September and new government stimulus measures mean there is now greater uncertainty over the country’s emissions trajectory.
Heatwaves through much of August and September caused a major increase in electricity demand for air conditioning, which, combined with weak hydropower output, meant a 2% increase in coal-fired power generation and a 13% rise for gas-fired power in the third quarter, despite wind and solar growth continuing to break records.
The increase in emissions in the power sector was offset by falling emissions from steel, cement and oil use, plus stagnating gas demand outside the power sector, meaning China’s CO2 output in the third quarter was flat or slightly declined, relative to a year earlier.
Other key findings from the analysis include:
- Solar generation rose 44% in the third quarter of the year and wind by 24%, with both continuing to see record-breaking additions of new capacity.
- Hydro generation was up 11% compared with last year’s drought-affected figures, but remained short of expected output. Nuclear power was up 4%.
- Oil demand fell by around 2%, due to falling construction activity, the rise of electric vehicles (EVs) and natural gas (LNG) trucks, as well as weak consumer spending.
- Emissions from steel fell by 3% and cement by 12% in the third quarter, as both sectors continued to see the effect of falling construction activity.
- The coal-to-chemicals industry received renewed political backing and coal consumption in the sector has risen by nearly a fifth in the year to date.
Emissions would need to fall by at least 2% in the last three months of the year, for China’s annual total to drop from 2023 levels. This outcome is supported by the ongoing slowdown in industrial power demand growth and the end of the air-conditioning season.
However, new economic stimulus plans announced in late September with no apparent emphasis on emissions, add uncertainty to this outlook.
In any case, China will remain off track against its 2025 “carbon intensity” target, which requires emissions cuts of at least 2% in 2024 and 2025, after rapid rises in 2020-23.
Looking further ahead, policymakers recently provided new indications of the country’s plans for peaking and reducing emissions, signalling a gradual and cautious approach which falls short of what would be needed to align with the goals of the Paris Agreement.
But, if the country’s rapid clean energy growth is sustained, it has the potential to deliver emission reductions more swiftly.
Clean-energy expansion met all power-demand growth over summer
Defying predictions of slowing growth, China’s electricity demand increased by 7.2% year-on-year in the third quarter of 2024, up from an already rapid 6.9% in the second quarter.
The make-up of growth changed, however. Some 60% of the increase in demand came from the residential and services sectors, with household demand up by a blistering 15%.
Industrial power-demand growth continued to slow down, increasing by 4.6% in July–September, down from 5.9% in the second quarter.
At the same time, solar power generation increased by 44% year-on-year and wind power generation by 24%. Hydropower grew 11%, despite falling short of average utilisation, and nuclear power generation growth was muted at 4% due to few new reactors being commissioned.
The rapid rise of electricity demand outpaced these increases from low-carbon sources, with the gap between demand and rising clean supply being met by a 2% increase in coal-fired power generation and a 13% rise for gas-fired power, as shown in the figure below.
This caused a 3% increase in CO2 emissions from the sector in the third quarter of the year.

However, looking at the whole summer period, whether taken as May-September or June-August, clean-energy expansion covered all of electricity demand growth.
This year, August and September were hotter than last year, resulting in rapid growth in power demand for air conditioning. Last year, in contrast, June and July were hotter.
Thermal power generation from coal and gas fell overall during the summer period, despite the rapid increase in residential power demand, with a 7% drop in June, 5% drop in July, a 4% increase in August and a 9% increase in September. Growth rates during individual months are heavily affected by which months the worst heatwaves fall on.
In terms of newly built generating capacity, solar continued to break last year’s records, with 163 gigawatts (GW) added in the first nine months of 2024. This is equal to the combined total capacity in Germany, Spain, Italy and France, the four EU countries with the most solar capacity. China’s solar capacity additions in the third quarter were up 22% year-on-year, as shown in the figure below.

The growth in China’s solar power output this year alone is likely to equal the total power generation of Australia or Vietnam in 2023, based on growth rates during the first nine months of the year.
Wind power additions accelerated as well, with 38GW added in the year to September, up 10% year-on-year and exceeding the total wind power capacity in the UK of 30GW.
China’s State Council approved 11 new nuclear reactors for construction in one go in August. The total power generating capacity of the approved projects is about 13GW. With 10 reactors approved in both 2022 and 2023 – and now 11 in 2024 – the next batch of nuclear power capacity is getting off the ground and adding to China’s clean-energy growth.
Hydropower capacity only increased 2% year-on-year, implying that most of the 11% third-quarter increase in generation was due to a recovery in capacity utilisation.
In response to severe droughts, utilisation had fallen to its lowest level in more than a decade in 2022, and recovered only partially in 2023, so this year’s recovery was expected and is closer to expected average hydropower generation.
China’s approvals of new coal power plant projects plummeted by 80% in the first half of 2024. Just 9GW of new capacity was approved, down from 52GW in the first half of last year. However, according to the Polaris Network, an energy sector news and data provider, eight large coal power projects were approved in the third quarter, likely representing an uptick in the rate of approvals compared with the first half of the year.
Construction and oil demand slowdown continued to pull down total emissions
While power sector emissions saw a small amount of growth in the third quarter of 2024, the ongoing contraction in construction volumes pulled down total emissions.
As a result, CO2 emissions stayed flat in the third quarter of 2024, at or just below the levels seen in the same period a year earlier, as shown in the figure below.

Digging deeper into the construction-led decline in emissions outside the power sector, steel output fell 9% and cement 12%, as real estate investment contracted 10% in the third quarter, maintaining the same rate as in the first half-year.
This translated into an 11% (24m tonnes of CO2, MtCO2) reduction in CO2 emissions from cement compared with the same period in 2023, shown in the figure below.
Steel emissions only fell by 3% (13MtCO2), despite the 9% fall in steel production. The reason is that the brunt of the drop in demand was borne by electric arc steelmakers rather than the coal-based steel plants with a much higher emission intensity.
The sector lacks the incentive to prioritise electric arc furnaces, which use recycled scrap and have much lower emissions. In theory, this could be encouraged by the inclusion of steel in China’s emissions trading system.
However, if the sector is treated in the same way as power, with separate benchmarks for coal-based and electric steelmaking, it will not create incentives to switch to electricity.
As one step towards structural change in the sector, the industry ministry issued a policy suspending all permitting of new steelmaking capacity, turning a de-facto stop to new permits – observed since the beginning of the year – into a formal moratorium. Until last year, the sector had been investing heavily in new coal-based steel capacity.

The other major area where emissions fell is oil consumption, which saw a 2% (13MtCO2) reduction in oil-related CO2 emissions in the third quarter of the year, also shown in the figure above. This is based on numbers from the National Bureau of Statistics.
The reduction in oil demand and related CO2 emissions may have been even steeper. The supply of oil products, measured as refinery throughput net of imports and exports, fell much more sharply. Based on this measure, CO2 from burning oil fell 10% (63MtCO2) in the third quarter, meaning that China’s CO2 emissions overall would have fallen by 2%.
The much more modest drop reported by the statistics agency could reflect the tendency of China’s statistical reporting to smooth downturns and upticks.
Another possible explanation is that refineries had previously been producing more than was being consumed, and have now had to cut output to reduce inventories.
Regardless of the magnitude of the drop, it is possible to identify the drivers of falling oil consumption. The fall in construction volumes is a major factor, as a significant share of diesel is used at construction sites and for transporting building materials.
The increase in the share of EVs is eating into petrol demand. Demand was also driven down by household spending, which remained weak until picking up in October in response to expectations of government stimulus.
The increasing share of trucks running on LNG also contributed to the fall in diesel demand. LNG truck sales accounted for about 20% of total truck sales in the nine months to March 2024, but weak overall gas demand growth indicates that this had a limited impact.
Gas consumption growth slowed down to 3% in the third quarter, from 10% in the first half of the year. Growth took place entirely in the power sector, with demand from other sectors stagnating, likely due to weak industrial demand.
After an increase in emissions in January-February, falling emissions in March-August and an increase in September, emissions would need to fall by at least 2% in the last three months of the year, for China’s annual total to drop from 2023 levels.
There is a good chance this will happen, due to an ongoing slowdown in industrial power demand growth and the end of the air conditioning season. But, even then, China would remain off track against its 2025 carbon intensity target, which requires emissions to fall by at least 2% in both 2024 and 2025, after rapid increases from 2020 to 2023.
The fundamental reason why emissions have not fallen faster – and may not have fallen at all in the third quarter – is that energy consumption growth this year continues to be much faster than historical trends.
Total energy consumption – including, but not limited to electricity consumption – grew 5.0% in the third quarter, faster than GDP, which gained 4.6%.
Until the Covid-19 pandemic, China’s energy demand growth had been much slower than GDP growth, implying falling energy intensity of the economy.
The post-Covid economic policy focused on manufacturing appears to have reversed this trend.
Coal-to-chemicals industry received new political backing
One additional wildcard in the outlook for China’s CO2 emissions is the coal-to-chemicals industry. The sector turns domestic coal into replacements for imported oil and gas, albeit with a far higher carbon footprint.
A recent policy from the National Development and Reform Commission, China’s powerful planning agency, called for ”accelerating” the development of the coal-to-chemical industry, including “speeding up the construction of strategic bases for coal-to-oil and coal-to-gas production”.
The past weeks after the issuance of the new policy have seen construction starts of a major coal-to-oil project in Shanxi, a coal-to-chemicals park in Sha’anxi and approval of a similar project in Xinjiang.
The coal-to-chemicals industry is expected to use more than 7% of all coal consumed in China in 2024, according to China Futures Research, a consultancy.
Coal consumption by the chemicals industry increased 18% in the first eight months of 2024, after a 9% increase in 2023, based on data from Wind Financial Terminal. This increase in coal consumption for coal-to-chemicals contributed two thirds of the 0.9% increase in total fossil CO2 emissions during the January to August period.
Coal consumption growth in the sector slowed down to 5% in July-August, however, and output of chemical products continued to slow in September. This smaller contribution to growth in CO2 emissions is shown in the graph above (“chemical industry”).
The recent rise in oil and gas prices, together with efforts to increase China’s domestic coal production and drive down domestic coal prices, have provided a major boost to the coal chemicals sector, which has a high sensitivity to both oil and coal prices.
Coal-to-chemicals is the sector where China’s policy priorities of energy security and emission reductions are most directly at odds.
Economic stimulus adds uncertainty to emissions outlook
After economic data indicated continuing slowdown and shortfall against GDP growth targets over the summer, expectations of a stimulus package built up.
The government responded in late September with a set of announcements, pledging various stimulus measures. The measures were focused on financial markets, but also included a commitment to “stabilise” the housing market.
The size of the stimulus package is not very large by China’s standards, and further details have disappointed those who hoped for a more radical policy turnaround. Yet, the package is clearly thought-through and coordinated, offering insights into how China’s top policymakers are planning to address the economic headwinds.
Direct income transfers of government money to households, which have been a hot topic for the past couple of years, are now going to be tried out.
Efforts to boost household spending, instead of the energy-intensive manufacturing and construction that has been the focus of previous rounds of government stimulus, would enable China to grow in a much less energy- and carbon-intensive way.
However, the sums allocated to income transfers are very small in relation to the size of the whole package. Much more money will be spent on subsidies to car and white-goods purchases. This will free up household cash for other types of spending, but it also directs household spending in the most energy-intensive direction.
Most of the stimulus is directed through the traditional routes of local government borrowing and bank lending, which tend to go into industrial and infrastructure projects.
There is no explicit climate-related emphasis to this stimulus. Quite a bit of it is likely to flow to clean energy-related investments, simply because those have been so dominant in China’s investment flows recently, but there is no further push in that direction.
Policymakers do not see an ‘early’ peak
While the rapid clean-energy growth points to the possibility of China’s emissions peaking imminently, policymakers are still setting an expectation that emissions will increase until the end of the decade and plateau or fall very gradually thereafter.
In August, China’s National Energy Administration played down the possibility of the country’s emissions having already peaked, in response to a question from a reporter referencing analyses suggesting this was possible.
The NEA department head who responded to the question emphasised that the timeline for peaking the country’s emissions – “before 2030” – has already been set by the top leadership, implying that the NEA has no mandate to change it.
The Central Committee of the Communist Party – one of the country’s highest leadership groups – reaffirmed that the aim is to “establish a falling trend” in emissions by 2035.
An earlier State Council plan said that China would focus on controlling total CO2 emissions, rather than emissions intensity, after the emission peak has been reached, and indicated that this would not happen in the 2026-30 period.
A very gradual approach to peaking emissions and reducing them after the peak, leaving more substantial emission reductions to later decades, is permissible under China’s current commitments under the Paris Agreement.
However, such a pathway would see the country use up 90% of the global emission budget for 1.5C. In scenarios that limit warming to 1.5C, China’s emissions are cut to at least 30% below 2023 levels by 2035. And recent International Energy Agency (IEA) analysis found that emerging markets such as China would need to cut emissions to 35-65% below 2022 levels by 2035, to align with the global pledges made at COP28 or national net-zero targets.
In contrast with the cautious approach telegraphed by Chinese policymakers, maintaining the rate of clean energy additions and electrification achieved in recent years could deliver a 30% reduction in CO2 emissions from fossil fuels by 2035, relative to 2023 levels.
Similarly, the IEA’s latest World Energy Outlook found clean-energy growth would help cut China’s CO2 emissions to 24% below 2023 levels by 2035, based on current policy settings. This reduction would increase to 45% by 2035 if China met its announced ambitions and targets, the IEA said.
China’s upcoming nationally determined contribution (NDC), due to be submitted to the UN under the Paris Agreement by February 2025, is expected to provide more clarity on which emissions pathway the policymakers are pursuing.
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. The effect of the adjustments is less than 1% for total emissions, with unadjusted numbers showing a 1% reduction 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.

Despite African walkout, fractious land COP ends without drought deal
The African continent’s hopes for a legally binding agreement to combat drought have been dashed again, as UN land restoration talks in Mongolia passed the issue onto the next set of talks in Egypt in two years’ time.
For over a decade, Africa has pushed for a UN protocol on drought risk management that would acknowledge drought as an issue requiring a regional and global – not just a national – response, potentially paving the way for more finance to help ensure water is available when drought hits.
A formal protocol would enable countries to transition from reacting to drought once it hits to “a proactive enabling mechanism to address drought and its effects such as migration”, said a Tunisian negotiator on behalf of the African Group of countries last week. Once land is regularly too dry and infertile to grow crops or graze animals, people often leave to seek a living elsewhere.
But this effort to adopt a protocol, led by Africa, has been resisted at successive land restoration COPs under the UN Convention to Combat Desertification (UNCCD), mainly by developed countries, which argue that a legally weaker alternative – a framework – would be faster and cheaper to set up.
Governments at the previous COP in Saudi Arabia in 2024 failed to reach agreement despite talks running past midnight, while this year’s saw African officials coordinate a walkout from negotiating rooms on Wednesday morning, according to two sources at the talks.
Drought deal delayed until 2028
The IISD’s Earth Negotiations Bulletin, a non-governmental organisation which unlike the media is allowed to watch and report on closed-door talks, said a call to suspend negotiations on Wednesday showed negotiations had reached “boiling point” and “made some jaws drop”.
Negotiations resumed after a lunchtime meeting with the Mongolian COP presidency although governments were only eventually able to agree that they could not find consensus in Ulaanbaatar and should resume talks on an instrument to deal with drought in 2028.
Christine Colvin, WWF’s head of freshwater policy, told Climate Home News that, with droughts hitting from Honduras to the English region of Hampshire, something concrete – whether a protocol or a framework – is needed urgently “rather than the can being kicked down the road for another two years as will now happen with the protocol procrastination”.

But, in a closing press conference on Friday, the Mongolian minister presiding over talks celebrated that governments had reached consensus on several “contentious” issues and that agenda items blocked at this year’s COP17 would be put on the agenda for COP18 in Egypt.
US blocks agenda items
Other agenda items that divided countries were on measuring land degradation’s effects on women, enhancing the involvement of civil society and women in land COPs, and the UNCCD working more closely and effectively with the UN’s climate and nature conventions.
On the COP’s opening day two weeks ago, the US representative said the Trump government objects to these agenda items “on their premise and no amount of negotiation will allow us to join consensus on these items. As such we request that they be struck from the agenda at which time we will then be able to approve it, saving us valuable negotiating time.”
A US State Department spokesperson later told Climate Home News that the US wants the UN “to get back to basics by refocusing on its core mandate, eliminating overlap, and reducing competition for scarce resources”.
The spokesperson added, “that means prioritising the concrete work member states created [the UN] to do – rather than diverting limited time, attention, and resources toward social and political agendas, including gender-related initiatives.”

On COP’s first day, the European Union and Brazil pushed back against the blocking of these agenda items, with a Brazilian negotiator saying his country attaches “great importance” to them. But the Mongolian presidency directed governments to adopt the rest of the agenda without the controversial items, which were discussed privately with countries throughout the two weeks.
An EU statement, read out later by Irish minister Timmy Dooley, accused “some parties” (meaning national governments) of having adopted a “less constructive approach” and preventing “discussions on important matters from even commencing”.
The agenda items the US refused to engage with were never discussed and were only placed onto the agenda for the next COP on the last day. Those talks will take place in Egypt in two years’ time, with Donald Trump due then to be in his last year as US president.
No restoration without women
The blocking of the gender agenda item has stymied attempts, agreed on by governments at the last COP, to develop gender-specific indicators for the UNCCD’s next overall framework and to facilitate more women delegates at COPs. Women made up only about a quarter of delegates to COP15 in 2022, UNCCD analysis with the latest data shows
Criticising the move to keep gender off the agenda, the EU said in a statement that it welcomes “the attention being given at COP17 to women pastoralists and herders, recognising their contribution to sustainable land management and resilient rural livelihoods”.
The head of the UNCCD, former Egyptian environment minister Yasmine Fouad, said on Friday that “regardless that the agenda item was blocked”, she was proud that she and COP17 President Batmunkh Battsetseg had led the COP as women and attended the gender caucus (a meeting of groups supporting women at the talks).

“Without the women,” she told the closing press conference on Friday, “we will not be able to restore land, restore hope, restore life or restore even our children and grandchildren. And we will keep on pushing that agenda.”
The civil society agenda item aimed to allow NGOs to attend land COP negotiations, as they do at climate COPs, and included terms of reference for an Indigenous Peoples Caucus.
A representative of Indigenous Peoples told the COP’s closing plenary meeting that the group had “deep disappointment that the agenda of this COP has removed the dedicated space for indigenous peoples”. “We cannot restore the land while removing the voices of those who care for it,” she said.
On Tuesday, the UNCCD’s deputy head Andrea Meza was asked about Indigenous Peoples’ participation. She said that the blocking of “one agenda item” is “generating uncertainty in the progress” towards creating caucuses for Indigenous Peoples and for Local Communities within the talks.
Because of the “complex geopolitical situation” making it hard to obtain consensus, coalitions of the willing have become more important, she added.
Mining out, money in
Outside the formal negotiations, the summit was marked by a focus on the strongly Mongolian issues of the role played by pastoralists and rangelands like grasslands, as well as mining, in both degrading and restoring land.
Part of the conference was sponsored by Australian mining company Rio Tinto and its local partner Oyu Tolgoi. Their presence was protested by campaigners wearing T-shirts calling on the companies to “stop wasting drinking water” and to “get out of Mongolia”.

The UNCDD and others praised the success of the summit in raising more finance for land restoration. The COP saw institutions like the Asian Development Bank and Global Environment Facility pledge money to combat land degradation, with the UNCCD estimating that $645 million of new commitments were made.
An estimated $355 billion a year is needed through 2030 to meet global land restoration commitments, compared with around $77 billion currently invested. Private finance accounts for only around 6% of global investment, according to the UNCCD.
UNCCD chief scientist Baron Orr told a press conference that many of the announcements were public-private partnerships that use government money to “even the playing field” for companies that want to protect land, in a bid to ensure they are not disadvantaged compared with those that do not.
Such partnerships are a “huge opportunity”, he said, especially as “we’re not in a moment of public finance – public finance is tight in every country.”

Pacific islands seek backing for new regional fund ahead of COP31
Burdened by rising fuel import costs and an “ocean crisis” of record-breaking heat, Pacific island nations are seeking to build support for a new regional fund ahead of COP31, intended to channel investment into renewable energy, community resilience and ocean protection, experts said.
Leaders from the 18-member Pacific Islands Forum (PIF), including Australia and New Zealand, are expected to issue a call for global pledges to the Pacific Resilience Facility (PRF) at a high-level meeting this coming week in Palau, seeking to build a new model for financing climate action.
The new regional fund was formally launched in May this year and is meant to “serve communities at a community level”, swiftly channelling investments for their projects on the ground, according to Fiji’s assistant minister for foreign affairs, Lenora Qereqeretabua.
“We are expecting pledges for the PRF, and these funds will go to communities that apply,” she told journalists at an online briefing. “We have organised it in such a way that it makes our application processes much, much easier than applying for global funding.”
Qereqeretabua added that she expects that PRF funds will be “utilised by communities to protect themselves from climate change and the effects of climate change.”
The Pacific Islands Forum meeting is expected to shape the region’s priorities ahead of this year’s pre-COP, hosted by Fiji and Tuvalu, and COP31, which will be co-led by Australia and Türkiye.
At COP31, a dedicated session on the climate finance needs of small island states will seek to drive pledges into the PRF. The fund has so far received about $172 million in capital – with about $67 million coming from Australia – and aims to close the year with $500 million.
Ocean heat and fossil fuel shocks
Leaders from the Pacific will meet in Palau from Sunday amid an “ocean crisis” of record-breaking ocean heat caused by this year’s “super El Niño”, according to Kevin Chand, Pacific ocean policy director at National Geographic’s Pristine Seas conservation project.
Leaders at the PIF are expected to put forward commitments towards new marine protected areas, which will be key for shielding ecosystems from future climate extremes, Chand said. The forum is expected to issue a statement on the need for ocean action at COP31, and announce commitments towards reaching the global goal of protecting 30% of the planet’s land and sea ecosystems by 2030.
Rising ocean heat could lead to food insecurity and lost government earnings in the region, as key fish stocks like tuna start migrating away from their coastline in search of colder waters, said Coral Pasisi, director of climate change and sustainability at the Pacific Community (SPC).
Climate shocks are deepening existing economic pressures, as Pacific nations have spent up to a quarter of their GDP on fossil fuel imports due to the war in Iran, according to a recent report by the University of New South Wales (UNSW) in Australia.
Wesley Morgan, one of the study’s authors, told journalists that partner nations “ought to be putting their money where their mouth is”, and should support the energy transition in the Pacific by covering the upfront costs of switching from polluting diesel to solar power, batteries and electricity grid upgrades.
China keeps Indonesia’s battery dream afloat but future less certain
Given the increase in climate-related shocks and sea-level rise, the PIF should also mention the need to phase out fossil fuel extraction and consumption, said Sindra Sharma, international policy lead at the Pacific Islands Climate Action Network (PICAN).
Last year’s COP30 failed to deliver a global roadmap on transitioning away from fossil fuels, which led to a group of countries – including several Pacific island nations – pursuing their own fossil fuel phase-out summit in Santa Marta, Colombia. Next year’s conference will be hosted by Tuvalu and co-chaired by Ireland, which should also receive backing from the PIF, Sharma said.
Both the chairs of the Santa Marta coalition and the Australian COP31 co-presidency have vowed to continue a push for this topic to be discussed at COP31.

New fund to test allies
As local communities in the Pacific struggle to access global climate funds, the PRF’s planned model for quick, direct disbursements has “very solid and good” intentions, Sharma said, but it will need political and financial backing from donor countries.
“The proof is going to be when the fund actually starts operating and delivering to communities,” she added. “If there is too much bureaucracy in being able to access the funds, for example. These things will have to be scrutinised.”
The facility aims to deliver funds in two categories: one for climate adaptation and “disaster resilience”, and another for social and community resilience that includes areas like community capacity-building, education, data analytics and financial management, among others. It will launch its first call for proposals at the PIF.
Morgan added that Australia will need to “leverage global interests” so that funding is directed to the Pacific Resilience Facility “or else the Pacific won’t be able to trust Australia as a partner”. The country ratified the PRF treaty in May, triggering its entry into force.
“The perception [of Australia] in the region is genuinely divided, and it’s worth being honest about it,” Sharma said, adding that the pre-COP31 in Fiji, which is usually limited to a technical space for negotiations, will determine how meaningful Australia’s advocacy for the Pacific can be.
This time, Pacific nations want to use the pre-COP in early October as an opportunity to demonstrate the challenges their largely low-lying islands face and to advocate for their political priorities, including a renewed global effort to limit global warming to 1.5C by cutting emissions faster and deeper. World leaders are due to visit Tuvalu to experience the frontline of rising sea levels, although Australia and Fiji have yet to confirm who will attend.
“In Bonn, Australia was largely missing on the negotiated outcomes that we so urgently need to see. It’s not enough to get Pacific priorities on the agenda. Agenda placement is not delivery,” Sharma added.

Climate change exposes 580 million children to 20 extra ‘heat-stress days’ every year
More than 40% of children under the age of 10 globally are already experiencing at least 20 additional “heat-stress days” due to climate change.
This is according to a new attribution study, published in Science Advances, which combines climate models with demographic data to assess the age groups and regions that are exposed to the most hot, humid days.
The study finds that children up to the age of nine already face more additional heat-stress days globally as a result of climate change than any other age group.
It adds that south Asia and west Africa are recording the greatest childhood exposure to dangerous levels of humid heat – largely because these regions have a rapidly growing population with the highest proportion of young children.
As the climate warms, children will continue to be more exposed to heat stress than any other age group, the paper warns.
The lead author of the study tells Carbon Brief that the findings should inform discussions about climate justice, noting that children in developing countries “have contributed the least to historical greenhouse gas emissions”.
Humid heat
High temperatures can be deadly. For example, the heatwaves that swept across Europe in the summer of 2026 have been linked to tens of thousands of “excess deaths”.
A prominent 2021 study found that children born in the 21st century will be exposed to more extreme weather events in their lifetimes than their parents and grandparents.
Four years later, a study conducted by scientists from the same team found that more than half of children born in 2020 – around 62 million people – will experience “unprecedented lifetime exposure” to heatwaves, even if warming is limited to 1.5C.
Now, the latest research from the same team finds that children already face greater exposure to dangerous levels of humid heat than adults as a result of human-caused climate change.
Extreme heat is particularly dangerous when combined with high humidity. In hot weather, the human body produces sweat to cool itself down. However, as humidity increases, sweating becomes less effective.
The study uses wet-bulb globe temperature – a measure of temperature that takes humidity and wind into account – to calculate heat stress. It defines a “heat-stress day” as any day with a wet-bulb globe temperature above 28C, as this is considered the threshold for “moderate heat stress”
The authors then use climate models to simulate global temperature patterns in the present-day climate. (The authors use the climate of 2023, in which human activity has caused 1.3C of warming, to represent the “present-day”.)
They then count the number of heat-stress days that each country records on average, per year. The authors then repeat this exercise, simulating a pre-industrial climate without human-caused warming.
By comparing the number of heat-stress days in the present-day climate with the number in a pre-industrial climate, the authors can determine how many extra heat-stress days were driven by climate change. They refer to these as “extra” or “attributable” heat-stress days.
The authors find that “low-latitude” countries, located in the tropics, record the most extra heat-stress days.
For example, the paper finds that people living in Côte d’Ivoire currently face 112 heat-stress days every year. It adds that around half of these are due to human-caused climate change.
In contrast, Germany sees only 0.1 heat-stress days per year in today’s climate on average, which is largely attributable to human-caused climate change.
Rosa Pietroiusti, a PhD student at Vrije Universiteit Brussel and lead author on the study, explains why this number may seem lower than expected.
She tells Carbon Brief that the paper “really focuses on humid heat, at levels that are relatively rarely felt in Europe”. She adds:
“Our data also doesn’t capture the urban heat island effect, due to the resolution of the data we use, which also would lead to underestimations of heat stress locally, and lead to a mismatch with what people are experiencing at local scales, particularly in cities.”
Inequality
Extreme heat affects some people more severely than others. Children, people over 65 and those with pre-existing medical conditions or certain disabilities are among the most vulnerable. This is because their bodies are less able to regulate their temperature.
The authors use gridded demographic data to determine the age structure of each country. From this, they calculate how many people from each age cohort are exposed to extra heat days as a result of climate change.
The research finds that globally, 583 million children under the age of 10 already live through at least 20 attributable heat days every year. This accounts for 44% of all children in this age bracket.
In comparison, 190 million people aged 60-69 face at least 20 attributable heat days per year, accounting for 30% of this age cohort.
The authors find that children face the greatest exposure to humid heat for two main reasons.
First, there are more young people alive today than older people, with 1.3 billion children aged under 10 in the world, compared to 0.6 billion people aged 60-69.
Second, they find that countries in Africa and Asia typically have rapidly growing populations with more young children. In contrast, many countries in the northern hemisphere – which are typically cooler – have older populations.
The map below shows how many extra stress heat days each country currently faces as a result of human-caused climate change. Darker reds indicate a higher number of attributable heat days. The blue circles show the percentage of the population under the age of 10, with larger circles indicating a higher percentage.

Warming world
The authors also repeat their analysis for a 1.5C and 2C warmer world. They use population estimates from the SSP2 scenario, which projects that the world’s population will peak at more than nine billion in the second half of the 21st century, with most growth occurring in low-latitude regions – especially in sub-Saharan Africa.
The research finds that, in today’s climate, 11% of all under 10s currently experience 100 or more extra heat-stress days per year due to climate change. In worlds warmed by 1.5C and 2C, the percentage rises to 13% and 23%, respectively.
In contrast, only 6% of all people aged 60-69 currently face 100 or more extra heat-stress days each year due to climate change. This number rises to 9% and 17% for 1.5C and 2C worlds, respectively.
These results are shown in the plot below. The three rows represent the climates of 2023 (top), a 1.5C world (middle) and a 2C world (bottom). The columns show different age cohorts, from the oldest on the left to the youngest on the right.
Each circle contains 100 coloured dots, with each dot representing 1% of the age cohort.
The colour of the dot represents exposure to annual heat-stress day, with darker dots indicating more heat-stress days. Grey dots mean that people experience fewer than one extra heat-stress day per year due to human-caused climate change, while black dots mean more than 150 extra heat-stress days due to climate change.
The figure shows that higher warming levels expose more people to heat stress and that younger cohorts tend to be worst affected.
For example, the top-right circle represents heat stress for under 10s in the present-day climate. Three of these dots are coloured black, indicating that 3% faced at least 150 attributable heat-stress days in 2023.

Pietroiusti tells Carbon Brief the study uses wet-bulb temperature because it is a “well-established heat stress metric”. However, she notes that it was not “explicitly defined to focus on children”. She continues:
“A really important step forward in the research community would be to link up climate science and health science experts to do research on what metrics are really most representative of, for example, health impacts and educational impacts that children will be suffering.”
Vulnerability
Dr Qinqin Kong, a postdoctoral researcher at the departments of medicine and health policy at Stanford University, who was not involved in the study, praises its “robust” methodology.
He tells Carbon Brief that the research provides “a timely quantitative evidence for discussions of climate justice, children’s rights and intergenerational equity”.
However, Kong suggests that the paper “may overstate the contrast between children and the elderly and underestimate the relative burden of older adults”.
He says:
“The elderly may also be more vulnerable due to their social circumstances. Children often benefit from parental supervision and caregiving, whereas many older adults live alone, have limited mobility and face barriers to accessing cooling or emergency assistance during heat events.”
Kong also notes that “people and societies in the mid-latitudes [for example, across much of Europe and North America] are less adapted to heat”, which may make them vulnerable to its impacts.
For example, he says that Europe “shows substantially stronger relative risk of heat mortality likely due to less heat-acclimatised populations, lower air conditioning prevalence and urban designs that don’t favour heat dissipation”.
Similarly, Dr Daniel Vecellio – a researcher at the University of Nebraska, who was not involved in the study – tells Carbon Brief that children are an “understudied cohort”.
However, he says there is “reason for hope” because “children are typically pretty good behavioural adapters to extreme heat” and because people who are “chronically exposed to extreme heat” will “have a better chance at better acclimatisation”.
Pietroiusti tells Carbon Brief that global reporting on heatwaves is often skewed towards wealthier nations.
For example, she notes that large-scale databases of disasters, such as EM-DAT, often underrepresent heatwaves in Africa, due in part to a lack of news coverage and formal reporting. She adds:
“Studies like this, which start from the climate data, can start to fill some of these gaps.”
She adds that the paper should inform discussions about climate justice, noting that children in developing countries, who are most severely affected by the increase in heat-stress days, “have contributed the least to historical greenhouse gas emissions”.
