The UK government’s official climate advisers are now “more optimistic” that the country can hit its emissions targets than they were before the Labour government was elected in July 2024.
Speaking ahead of the launch of the Climate Change Committee’s 2025 progress report, Prof Piers Forster, the CCC’s interim chair, told journalists it would be “possible” to meet the UK’s 2030 international climate goal, as well as its 2050 target to cut emissions to net-zero.
Moreover, Forster responded to attacks on climate policy from opposition parties, the Conservatives and Reform UK, by saying that reaching net-zero would, “ultimately, be good for the UK economy”.
The CCC’s report points to progress in areas such as windfarm planning rules, plans for clean power by 2030 and the accelerating adoption of clean-energy technologies for heat and transport.
It says that 38% of the emissions cuts needed to hit the UK’s 2030 target are now backed by “credible” policies, up from 25% two years earlier.
However, it says “significant risks” remain – and its top recommendation is for government action to reduce electricity prices, which would support the electrification of heat, transport and industry.

Change of tone
This is the first progress report from the CCC to assess climate policy and action under the new Labour government, which took office in July 2024.
Last year’s edition had said that “urgent action is needed” and that the UK was “not on track” for its 2030 international climate goal, namely, a 68% reduction in emissions relative to 1990 levels.
In contrast, the 2025 report says: “This target is within reach, provided the government stays the course.”
Speaking at a pre-launch press briefing, CCC interim chair Prof Piers Forster said: “[This is] an optimistic report, [showing] that it is possible for the country to meet its climate commitments.”
Moreover, in comments aligned with the shift in language since last year, he said that the report was “more optimistic” than the 2024 edition. Forster explained:
“We are not a political organisation and our job as a committee is just to look at the evidence, but, in terms of looking at the evidence, we are more optimistic than we were this time last year.”
The reasons for this were a mixture of policies from the previous government starting to deliver and the impact of decisions taken by the new administration, he said.
While the tone is relatively optimistic, the latest progress report uses less prescriptive language than previous editions, according to Carbon Brief analysis shown in the figure below.
For example, the word “must” occurs once every 10 pages in this year’s report, down from seven times in 2021. Similarly, the word “should” only occurs four times per 10 pages, down from 13.
This shift in language appears to be a continuation of the approach taken by the committee in its advice on the UK’s seventh “carbon budget”, published in February.
(Under the Climate Change Act 2008, the government has until June 2026 to legislate for this budget, which is a legally binding emissions limit for the five-year period from 2038 to 2042.)
The committee has faced inaccurate criticism from some opponents of climate action, who have argued that it was, in effect, setting government policy.
Pushing back on this, Forster had reiterated in February: “[O]ur core responsibility…is to give…the very best non-partisan advice possible…It’s not up to us to make the policy, it’s up to government.”
Beyond the overall tone of the latest progress report, it also puts a stronger emphasis than last year’s on the need for action to reduce emissions.
It sets out the rationale for the world reaching net-zero carbon dioxide (CO2) emissions to stop global warming, but also asserts the benefits this would bring to the UK in terms of energy security, a more efficient economy and lower bills:
“[C]ontinued reliance on fossil fuels undermines UK energy security…[A] fossil-fuelled future would leave the UK increasingly dependent on imports, and energy bills would remain subject to volatile fossil fuel prices.”
In language that could be interpreted as pushback against the leader of the opposition, the Conservative’s Kemi Badenoch, who recently falsely claimed that reaching net-zero emissions by 2050 was both “impossible” and only possible “by bankrupting us”, the CCC report states:
“The science is unambiguous. Only by achieving net-zero CO2 emissions, with deep reductions in other greenhouse gases, can the UK stop contributing to an ever-warmer climate…The 2050 net-zero target for the UK remains deliverable and affordable, with whole-economy costs estimated at an annual average of 0.2% of GDP.”
Asked directly if he agreed that the net-zero by 2050 target was “impossible” and would come with “catastrophic” costs – as Badenoch has asserted – Forster said that on the contrary, it was “possible” and would, “ultimately, be good for the UK economy”. He told journalists:
“We think that, provided there is further government policy, it is possible both to reach our [2030 target], our carbon budgets and then, ultimately, get to net-zero…[and that] while the benefit doesn’t come instantly…it will, ultimately, be good for the UK economy.”
The report also makes the point that the UK is far from alone in its efforts, with global investments in clean-energy technologies reaching $2tn last year, double the sum going to fossil fuels. It adds:
“Most of the world is investing heavily in low-carbon technologies, driven by falling costs, energy security concerns and a realisation of the need to respond to rising climate impacts.”
(This is despite the Trump administration’s withdrawal from the Paris Agreement and a “period of uncertainty” in international relations since the US election, the report notes.)
Overall progress
Last year’s report, published just days after Labour’s “landslide” election victory, had set the scene for the new administration, saying that it needed to “make up lost ground” to get back on track.
That report had called on the new government to “limit the damage” from Conservative climate policy rollbacks, which had been implemented ahead of the election.
This year’s report looks at how things have progressed since then, based on three sets of metrics:
- First, it looks at changes to the UK’s greenhouse gas emissions over the past year.
- Second, it looks at indicators of progress on the ground, such as the uptake of electric vehicles (EVs), the rollout of electric heat pumps and the rate of tree-planting.
- Third, it looks at policy changes introduced over the past year by the new government.
The assessment includes policy changes introduced up until 23 May 2025, meaning that it does not consider the June spending review or the industrial strategy published earlier this week.
Greenhouse gas emissions have more than halved since 1990, with a 50.4% reduction, making the UK “one of the leading economies in the world”, Forster said. The report adds:
“The UK should…be proud of its place among a leading group of economies demonstrating consistent and sustained decarbonisation.”
It says that UK emissions fell again during 2024, with a 2.5% reduction marking the tenth year of steady decline, excluding the Covid-19 pandemic and subsequent rebound.
Echoing Carbon Brief analysis published in March, the CCC says that the latest drop in emissions was due to the power sector, industry and transport, where EVs are starting to have an impact.
However, the report emphasises once again that progress to date has largely come in the electricity sector, where the UK became the first country in the G7 to phase out coal power in 2024.
Indeed, the CCC says that electricity supply is now only the UK’s sixth-largest source of emissions, after surface transport, buildings, industry, agriculture and aviation, as shown in the figure below.
In order to continue cutting emissions to meet UK climate goals, the CCC says that reductions will be needed across a broader range of sectors, including transport, buildings, industry and land-use.
The pace of emissions cuts outside the power sector – an average of 8m tonnes of CO2 equivalent (MtCO2e) per year since 2008 – is roughly on track for the fourth carbon budget covering 2023-27.
However, the report says this pace will need to “more than double” toward the end of the decade, hitting 19MtCO2e per year, in order to hit the UK’s NDC and sixth carbon budget.
Turning to the indicators of progress on the ground, the CCC says that there are some “clear signs” of such shifts starting to take place, in areas such as transport, buildings and land-use.
For example, the report points to “significant increases” in the rates of heat-pump rollout (up 56% year-on-year in 2024), tree-planting (+59%) and peatland restoration (+47%).
(See the sections below for further detail on policies and progress in each sector.)
Policy gaps
Turning to its assessment of government climate policy, the CCC report says there has also been some “positive progress” since Labour came to office last year.
Specifically, it points to the removal of planning barriers for onshore wind and heat pumps, as well as implementation of the “clean heat market mechanism” to drive heat-pump sales, reinstatement of the 2030 combustion car ban and publication of the 2030 clean-power action plan.
As a result, the CCC says that there are now “credible policies” in place to make 38% of the emissions cuts needed to hit the UK’s 2030 target, up from 25% in 2023 and 32% last year.
At the same time, the share of emissions savings subject to policies facing “some” or “significant risks” has fallen from 53% in 2023 and 50% in 2024, down to 43% in the latest report.
These improvements are illustrated in the figure below, which shows that the credibility of UK climate policies towards the 2030 target has been steadily increasing.
Nevertheless, there are still “insufficient plans” to make 14% of the cuts needed by 2030, the same share as last year. The biggest policy gaps are around heat-pump rollout, the report says.
The CCC says: “With 39% of policies and plans needed to hit the 2030 NDC rated as having significant risks, or insufficient or unquantified plans, the government must act swiftly.”
The figure below illustrates the implications of falling to “act swiftly” more clearly.
If only the most “credible” policies actually deliver emissions savings (solid dark blue line) then the UK would miss its international targets for 2030 and 2035 (black circles) by significant margins.
The UK would get somewhat closer to its goals, if emissions cuts are successfully achieved as a result of policies subject to “some” (light blue) or “significant” delivery risks (grey line).
At the pre-launch briefing, Dr Emily Nurse, head of net-zero at the CCC, told journalists that further action was needed to get on track for the 2030 target. She said:
“Around three-fifths of what’s needed is covered by either credible plans or [those] having some risks…The UK can hit its upcoming emissions reduction targets and remain on track for net-zero, but only with further policy action.”
The government has the chance to fill these policy gaps when it publishes its updated “carbon budget delivery plan”, which has a deadline of 29 October this year.
This plan must set out how the government intends to meet the UK’s legally binding climate goals, after the previous administration’s plan was ruled unlawful by the High Court.
While there has been “good or moderate progress” on 20 of the 35 policy recommendations made last year, the CCC says there has been “no progress” on its top recommendation to make electricity cheaper.
The report says this remains its top recommendation for the second year in a row.
The reason for emphasising this, it says, is that electrification of transport, heat and industry will be the key to making required emissions cuts over the next decade, according to the CCC, with these shifts being facilitated by the expansion and continued decarbonisation of the power sector.
CCC chief executive Emma Pinchbeck told journalists that making progress in lowering electricity prices was “absolutely critical”, particularly relative to the price of gas. She said:
“The reason we keep banging on about [this], very simply, [is] that the evidence from every other country that’s had a successful rollout of electric technologies – particularly for heat – is that you need a three-to-one electricity-to-gas price ratio.”
(At present, domestic electricity prices are roughly four times higher than gas prices.)
Pinchbeck reiterated the committee’s call for the government to remove policy “levies” from electricity bills, adding that failing to do so would mean “slowing down” the transition. She said:
“If you’re effectively taxing your future fuel, you’re slowing down your energy transition, when the economy is going to become more and more dependent on electricity…It is just sensible economic policy to have cheap fuel going into your economy.”
While Pinchbeck welcomed plans in the government’s just-published industrial strategy to cut levies on industrial electricity bills, she said that it should do the same for households.
Road transport
Road-transport emissions fell for a second consecutive year in 2024, says the report.
The number of electric vehicles (EVs) on UK roads is roughly doubling every two years.
If this trend continues, the road-transport sector will produce the emissions savings required for its contribution to the UK’s 2030 climate target, the CCC says (see below).
EVs made up 19.6% of new car sales in 2024, compared to 16.1% the previous year, according to the report. In the first quarter of 2025, this figure rose to 20.7%.
This represents “strong growth”, but is below the headline targets of the zero-emission vehicle (ZEV) mandate, a government regulation that requires car manufacturers to sell an increasing percentage of zero-emission vehicles each year, the CCC says.
The mandate targets a 22% market share for 2024 and a 28% share for 2025, according to the CCC.
The CCC notes that lower-cost EVs are becoming increasingly available. It adds that “price parity with petrol cars has already been reached in parts of the second-hand market”, with this milestone set to arrive for new cars by between 2026 and 2028.
Overall, there has been a “small improvement” in the UK’s policy efforts to decarbonise road transport since last year’s report, it says.
This is largely down to Labour’s decision to reinstate a 2030 ban on the sale of new petrol and diesel vehicles, which was weakened to 2035 under Conservative prime minister Rishi Sunak, explains the report.
The CCC describes the move as a “welcome market signal to accelerate the transition to EVs”.
As well as reinstating the 2030 ban, the government announced changes to the ZEV mandate.
The government essentially weakened the mandate by extending flexibilities and allowing the sale of hybrid vehicles between 2030 and 2035.
Ministers said this move was in response to import tariffs announced by Donald Trump.
The CCC says the changes “risk allowing existing planned plugin hybrid vehicle sales to slightly reduce the emissions savings from EVs”, adding:
“It is also possible that manufacturers could divert investment towards [hybrids], diluting the consumer offer for EVs – we currently think that this risk is minimal due to progress in scaling up the EV market to date, but it is something that we will monitor closely.”
It adds that “for the transition to accelerate, further reductions in the cost of purchasing EVs, as well as improved access to, and reduced costs of, local public charging, are needed”.
Buildings
Heat pump installations increased by 56% in 2024 compared to the year before, the report says. Some 98,000 heat pumps were installed.
A total of 23,000 heat pumps were installed under the Boiler Upgrade Scheme, which allows homeowners to claim grants for replacing fossil-fuel boilers. This is an increase of 83% on 2023 levels, says the CCC.
However, the speed at which heat pumps are rolled out remains one of the “biggest risks” to the UK meeting its 2030 climate target, it adds.
The UK’s heat pump market share is around 4%, much lower than comparable countries, such as Ireland (30%) and the Netherlands (31%), the CCC says.
The government has taken steps to “remove planning barriers” for heat pumps. This includes amending the planning policy in England to remove the requirement for planning permission for heat pumps located less than 1m from a property boundary.
However, the government has “not yet provided clarity on whether [it] will continue with the proposed phase-out of new fossil fuel boiler installations from 2035”, or “make alternative plans to ensure that low-carbon heating reaches the installation rates required”, the CCC says.
The report adds that the ratio of residential electricity to gas prices is “significantly off track”.
The ratio is important because it underpins the “underlying cost savings of switching to electric technologies are reflected in the bills paid by households and businesses”, the CCC says, continuing:
“Action has not been taken to remove policy costs from electricity prices which would address this, despite it being our first recommendation last year…Currently, a typical household with a heat pump is paying around £490 per year in policy costs, which inflate their bills above the underlying cost of the additional electricity used.”
Data from other nations suggests that the “market share of heat pump installations are correlated with more favourable electricity-to-gas price ratios”, says the CCC (see chart below).
Forster told the press briefing that the CCC’s “biggest recommendation” to government remains reducing the price of electricity in relation to gas:
“By far the most important recommendation we have for the government is to reduce the cost of electricity, both for households and for businesses and industry as well…If we want the country to benefit from the transition to electrification, we have to see it reflected in utility bills.”
The report adds that, on efforts to increase the energy efficiency of residential buildings, the “proportion of homes with insulated cavity walls has steadily increased over recent years, but this will need to accelerate later in the decade” to be in line with net-zero.
Industry
Industry emissions decreased by 4.7MtCO2e in 2024, compared to the year before, the CCC says. Emissions are now 48% lower than 2008 levels.
From 2023-24, annual emissions dropped quickly due to the removal of blast furnaces at Port Talbot steelworks in 2024. They are due to be replaced by electric arc furnaces by 2027, with the move leading to 2,500 job losses.
The government should have developed a “more proactive and decisive transition plan” for Port Talbot and the report describes the UK’s upcoming steel strategy as “an opportunity to set out plans for the low-carbon transition at Scunthorpe steelworks and other UK steel production”.
To deliver the emissions savings needed to meet the UK’s 2030 climate goal, companies will “increasingly need to switch to electric alternatives to fossil-fuelled technology”, the report says, adding:
“A high ratio of [industrial] electricity-to-gas prices currently presents a barrier to this.”
It adds that, currently, “there is now no major source of government support for manufacturers to invest in electrification”.
The CCC notes that the government did not launch the latest round of the Industrial Energy Transformation Fund, which was due in December 2024. It has “not clarified whether this or similar funding will continue”.
On 23 June, the UK government announced a 10-year industrial strategy, including measures to slash the price of electricity for energy-intensive businesses from 2027 by exempting them from green levies.
In the press briefing, Pinchbeck described the move as “good”, but urged the government to introduce similar measures for household electricity bills, too. (See: Buildings.)
On efforts to introduce carbon capture and storage (CCS) technologies to UK industries, the report says progress “is not on track to be deployed at the pace required” by government plans to reach net-zero.
Fossil fuels and hydrogen
The report says that the UK’s “continued reliance on fossil fuels undermines energy security”, continuing:
“Household energy bills rose sharply following Russia’s invasion of Ukraine and have remained high since. It is the price of gas that has driven up both gas and electricity bills.”
(See Carbon Brief’s factcheck on what is causing high electricity bills in the UK.)
The report does not directly address the Labour government’s policies on oil and gas production in the North Sea.
Labour has ruled out new oil and gas licences. However, the government has indicated it might approve new projects that already have a licence, if they can pass a new environmental impact assessment that will consider the emissions from burning the oil and gas produced.
In regards to the North Sea, the report says:
“With North Sea resources largely used up, a fossil-fuelled future would leave the UK increasingly dependent on imports and energy bills would remain subject to volatile fossil fuel prices.”
The CCC adds that the “main progress in the fuel-supply sector in the past year has been around low-carbon hydrogen production”.
In the 2024 autumn budget, the government confirmed support for 11 “electrolytic”
hydrogen production projects, which are expected to start operating by the end of 2026. (These projects use electricity to split water into hydrogen and oxygen.)
Electricity
The UK’s transition away from fossil fuels to renewable energy in its electricity supply continued to drive the bulk of emissions reductions in 2024, the CCC says. It accounted for 41% of the total in-year reduction in emissions.
From the 1990s until 2024, the power sector has transformed from the largest source of emissions to only the sixth largest, behind aviation. (See: Overall progress.)
The UK’s last coal-fired power plant, Ratcliffe-on-Soar, closed in October 2024. (See Carbon Brief’s detailed explainer on how the UK became the first G7 nation to phase out coal.)
Coal emissions from electricity generation were 99% lower in 2024 than in 2008 and will reach zero in 2025, the CCC says. It describes this as a “major milestone on the UK’s path to a decarbonised power system”.
Falling gas generation accounted for 72% of emissions reductions in the power sector in 2024, the CCC says.
The electricity supplied by gas fell by 15% in 2024, compared to the previous year. This was “made up with roughly equal proportions of imports and low-carbon generation”.
The rollout of wind and solar capacity in 2024 was larger than in any of the previous six years, the report says.
But to achieve the government’s goal of “clean power” by 2030, total renewable capacity will need to more than double.
Based on projects in the pipeline, both offshore and onshore wind “appear on track” for the government’s goal, according to the CCC.
However, “roll-out of solar is significantly off track and will need to improve to deliver its contribution to a decarbonised electricity system”.
The report says that, overall, “positive policy progress has been made in decarbonising electricity supply over the past year”.
It continues that “concrete steps have been made to remove barriers and support the deployment of low-carbon technology”.
These steps include removing barriers facing onshore wind developments, “streamlin[ing]” the approval of nationally significant infrastructure, including renewable projects and introducing reforms to speed up connecting projects to the grid.
However, the CCC adds that there are “remaining uncertainties on the future electricity market arrangements and further challenges to deploying infrastructure to overcome”.
Agriculture and land
There was a “significant increase” in both tree-planting and peatland restoration in 2024, the report says.
Some 20,700 hectares of new trees were planted, an increase of 59% on the year before and the highest rate in 20 years, it adds, as shown in the chart below.
Over the same period, the restoration of peatlands increased by 47%.
This “demonstrates that a rapid increase in rates is feasible” for the land-use sector, the CCC says.
However, woodland creation remains “slightly off track”. (Carbon Brief reported last year that successive UK governments have fallen so far short of their tree-planting targets since 2020 that they have failed to plant an area of forest nearly equivalent to the size of Birmingham.)
In addition, Scotland accounted for 73% of the total trees planted from 2023-24 and the CCC has “concerns that recent reductions in funding for woodland creation in Scotland could reverse this trend”.
A target to have 35,000 hectares of peat under restoration in England by 2025 is also “expected to be missed”.
Livestock numbers continued to fall in 2024, the report says.
Meat eating has declined steeply over the past couple of years. The average amount of meat eaten per person each week dropped by around 100g from 2020-22, according to CCC data.
Pinchbeck told the press briefing that meat-eating in the UK is now lower than what the CCC had anticipated in its central pathway for meeting net-zero:
“There’s lots of factors behind that, including the cost of living crisis. So we are not necessarily saying that trend will increase. Farming is facing a number of pressures, outside having to deal with a changing climate, reduced crop yields [and] difficulty making farms sustainable.”
Both the reduction in livestock and meat eating are “key to freeing up land required to increase tree-planting and peatland restoration”, the report says.
The government’s progress on addressing land-use sector emissions with policies has been “mixed” over the past year, according to the CCC.
The government is expected to produce a long-awaited land-use framework by the end of this year, but it “remains unclear how this framework will drive change on the ground”, the advisers say.
The government paused the sustainable farming incentive, part of the environmental land management (ELM) schemes, in March 2025.
This was due to all of the funding being allocated, which is “positive”, says the CCC. However, the decision has left a “gap in delivery grants for on-farm actions”.
The Nature for Climate Fund has been extended by one year, but is “unclear” what will happen to this scheme in the long term, it adds.
Aviation and shipping
Emissions in the aviation sector increased by 9% year-on-year in 2024, “marking a return to pre-pandemic levels”, the report says.
In government and CCC scenarios for net-zero, emissions stay flat and start slowly decreasing over the rest of the decade, the report says, adding:
“Aviation emissions will likely exceed the trajectories assumed in all [these] pathways if they continue to increase, posing a risk to the UK’s emissions targets.”
The biggest driver of aviation emissions since 1990 has been “rising demand for international flights, particularly leisure”, it continues.
Aviation now causes more emissions than the UK’s entire power grid. In 1990, aviation emissions were 10 times lower than those from electricity, according to the report.
The CCC “recommends that the government should develop and implement policy that ensures the aviation sector takes responsibility for mitigating its emissions and, ultimately, achieving net-zero”, adding:
“This includes paying for permanent engineered removals to balance out all remaining emissions. Robust contingencies should also be in place to address any delays in decarbonisation, including through managing the forecasted increase in aviation demand.”
The share of sustainable aviation fuel (SAF) as a proportion of all jet fuel rose from 0.7% to 2.1% from 2023-24, the CCC says.
It notes that the SAF mandate came into force in January 2025 and the sustainable aviation fuel bill was introduced to parliament in May.
Achieving the government’s target of 10% of jet fuel from SAF by 2030 “remains uncertain as different types of SAF will need to scale up”, it adds.
There are currently no operational UK SAF plants, but some are under construction.
On shipping, the report notes that the UK has set out a maritime decarbonisation strategy, with an aim to reduce the domestic maritime sector’s fuel lifecycle emissions to zero by 2050 and interim goals of cutting pollution by 30% by 2030 and 80% by 2040, compared to 2008.
The targets are “broadly aligned” with government plans for net-zero, the CCC says.
Other sectors
Another sector tracked by the CCC is “engineered removals”, technologies that suck CO2 out of the atmosphere.
Aside from small experiments, there is no deployment of such technologies in the UK. However, the government’s pathway for net-zero expects such methods to remove 6MtCO2e from the atmosphere by 2030, the report says, adding:
“This sector will need to develop and scale up notably over the coming five years.”
One of the CCC’s “top 10” priority actions is for the government to “finalise business models for large-scale deployment of engineered removals”.
On this, the advisers say:
“There has been little progress…This puts the contribution of engineered removals to the UK’s 2030 NDC at increasing risk.”
Another issue assessed by the CCC is waste, which produced 26.7MtCO2e in 2024, making it the eighth most polluting sector.
The report says there has been “some progress” on waste policy, but notes the government is “yet to confirm its intention to prevent biodegradable waste from going to landfill, a key measure to reduce emissions from waste”.

CCC: UK climate advisers now ‘more optimistic’ net-zero goals can be met
Drought and heatwaves occurring together – known as “compound” events – have “surged” across the world since the early 2000s, a new study shows.
Compound drought and heat events (CDHEs) can have devastating effects, creating the ideal conditions for intense wildfires, such as Australia’s “Black Summer” of 2019-20 where bushfires burned 24m hectares and killed 33 people.
The research, published in Science Advances, finds that the increase in CDHEs is predominantly being driven by events that start with a heatwave.
The global area affected by such “heatwave-led” compound events has more than doubled between 1980-2001 and 2002-23, the study says.
The rapid increase in these events over the last 23 years cannot be explained solely by global warming, the authors note.
Since the late 1990s, feedbacks between the land and the atmosphere have become stronger, making heatwaves more likely to trigger drought conditions, they explain.
One of the study authors tells Carbon Brief that societies must pay greater attention to compound events, which can “cause severe impacts on ecosystems, agriculture and society”.
Compound events
CDHEs are extreme weather events where drought and heatwave conditions occur simultaneously – or shortly after each other – in the same region.
These events are often triggered by large-scale weather patterns, such as “blocking” highs, which can produce “prolonged” hot and dry conditions, according to the study.
Prof Sang-Wook Yeh is one of the study authors and a professor at the Ewha Womans University in South Korea. He tells Carbon Brief:
“When heatwaves and droughts occur together, the two hazards reinforce each other through land-atmosphere interactions. This amplifies surface heating and soil moisture deficits, making compound events more intense and damaging than single hazards.”
CDHEs can begin with either a heatwave or a drought.
The sequence of these extremes is important, the study says, as they have different drivers and impacts.
For example, in a CDHE where the heatwave was the precursor, increased direct sunshine causes more moisture loss from soils and plants, leading to a drought.
Conversely, in an event where the drought was the precursor, the lack of soil moisture means that less of the sun’s energy goes into evaporation and more goes into warming the Earth’s surface. This produces favourable conditions for heatwaves.
The study shows that the majority of CDHEs globally start out as a drought.
In recent years, there has been increasing focus on these events due to the devastating impact they have on agriculture, ecosystems and public health.
In Russia in the summer of 2010, a compound drought-heatwave event – and the associated wildfires – caused the death of nearly 55,000 people, the study notes.
The record-breaking Pacific north-west “heat dome” in 2021 triggered extreme drought conditions that caused “significant declines” in wheat yields, as well as in barley, canola and fruit production in British Columbia and Alberta, Canada, says the study.
Increasing events
To assess how CDHEs are changing, the researchers use daily reanalysis data to identify droughts and heatwaves events. (Reanalysis data combines past observations with climate models to create a historical climate record.) Then, using an algorithm, they analyse how these events overlap in both time and space.
The study covers the period from 1980 to 2023 and the world’s land surface, excluding polar regions where CDHEs are rare.
The research finds that the area of land affected by CDHEs has “increased substantially” since the early 2000s.
Heatwave-led events have been the main contributor to this increase, the study says, with their spatial extent rising 110% between 1980-2001 and 2002-23, compared to a 59% increase for drought-led events.
The map below shows the global distribution of CDHEs over 1980-2023. The charts show the percentage of the land surface affected by a heatwave-led CDHE (red) or a drought-led CDHE (yellow) in a given year (left) and relative increase in each CDHE type (right).
The study finds that CDHEs have occurred most frequently in northern South America, the southern US, eastern Europe, central Africa and south Asia.
Threshold passed
The authors explain that the increase in heatwave-led CDHEs is related to rising global temperatures, but that this does not tell the whole story.
In the earlier 22-year period of 1980-2001, the study finds that the spatial extent of heatwave-led CDHEs rises by 1.6% per 1C of global temperature rise. For the more-recent period of 2022-23, this increases “nearly eightfold” to 13.1%.
The change suggests that the rapid increase in the heatwave-led CDHEs occurred after the global average temperature “surpasse[d] a certain temperature threshold”, the paper says.
This threshold is an absolute global average temperature of 14.3C, the authors estimate (based on an 11-year average), which the world passed around the year 2000.
Investigating the recent surge in heatwave-leading CDHEs further, the researchers find a “regime shift” in land-atmosphere dynamics “toward a persistently intensified state after the late 1990s”.
In other words, the way that drier soils drive higher surface temperatures, and vice versa, is becoming stronger, resulting in more heatwave-led compound events.
Daily data
The research has some advantages over other previous studies, Yeh says. For instance, the new work uses daily estimations of CDHEs, compared to monthly data used in past research. This is “important for capturing the detailed occurrence” of these events, says Yeh.
He adds that another advantage of their study is that it distinguishes the sequence of droughts and heatwaves, which allows them to “better understand the differences” in the characteristics of CDHEs.
Dr Meryem Tanarhte is a climate scientist at the University Hassan II in Morocco, and Dr Ruth Cerezo Mota is a climatologist and a researcher at the National Autonomous University of Mexico. Both scientists, who were not involved in the study, agree that the daily estimations give a clearer picture of how CDHEs are changing.
Cerezo-Mota adds that another major contribution of the study is its global focus. She tells Carbon Brief that in some regions, such as Mexico and Africa, there is a lack of studies on CDHEs:
“Not because the events do not occur, but perhaps because [these regions] do not have all the data or the expertise to do so.”
However, she notes that the reanalysis data used by the study does have limitations with how it represents rainfall in some parts of the world.
Compound impacts
The study notes that if CDHEs continue to intensify – particularly events where heatwaves are the precursors – they could drive declining crop productivity, increased wildfire frequency and severe public health crises.
These impacts could be “much more rapid and severe as global warming continues”, Yeh tells Carbon Brief.
Tanarhte notes that these events can be forecasted up to 10 days ahead in many regions. Furthermore, she says, the strongest impacts can be prevented “through preparedness and adaptation”, including through “water management for agriculture, heatwave mitigation measures and wildfire mitigation”.
The study recommends reassessing current risk management strategies for these compound events. It also suggests incorporating the sequences of drought and heatwaves into compound event analysis frameworks “to enhance climate risk management”.
Cerezo-Mota says that it is clear that the world needs to be prepared for the increased occurrence of these events. She tells Carbon Brief:
“These [risk assessments and strategies] need to be carried out at the local level to understand the complexities of each region.”

DeBriefed 6 March 2026: Iran energy crisis | China climate plan | Bristol’s ‘pioneering’ wind turbine
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Energy crisis
ENERGY SPIKE: US-Israeli attacks on Iran and subsequent counterattacks across the Middle East have sent energy prices “soaring”, according to Reuters. The newswire reported that the region “accounts for just under a third of global oil production and almost a fifth of gas”. The Guardian noted that shipping traffic through the strait of Hormuz, which normally ferries 20% of the world’s oil, “all but ground to a halt”. The Financial Times reported that attacks by Iran on Middle East energy facilities – notably in Qatar – triggered the “biggest rise in gas prices since Russia’s full-scale invasion of Ukraine”.
‘RISK’ AND ‘BENEFITS’: Bloomberg reported on increases in diesel prices in Europe and the US, speculating that rising fuel costs could be “a risk for president Donald Trump”. US gas producers are “poised to benefit from the big disruption in global supply”, according to CNBC. Indian government sources told the Economic Times that Russia is prepared to “fulfil India’s energy demands”. China Daily quoted experts who said “China’s energy security remains fundamentally unshaken”, thanks to “emergency stockpiles and a wide array of import channels”.
‘ESSENTIAL’ RENEWABLES: Energy analysts said governments should cut their fossil-fuel reliance by investing in renewables, “rather than just seeking non-Gulf oil and gas suppliers”, reported Climate Home News. This message was echoed by UK business secretary Peter Kyle, who said “doubling down on renewables” was “essential” amid “regional instability”, according to the Daily Telegraph.
China’s climate plan
PEAK COAL?: China has set out its next “five-year plan” at the annual “two sessions” meeting of the National People’s Congress, including its climate strategy out to 2030, according to the Hong Kong-based South China Morning Post. The plan called for China to cut its carbon emissions per unit of gross domestic product (GDP) by 17% from 2026 to 2030, which “may allow for continued increase in emissions given the rate of GDP growth”, reported Reuters. The newswire added that the plan also had targets to reach peak coal in the next five years and replace 30m tonnes per year of coal with renewables.
ACTIVE YET PRUDENT: Bloomberg described the new plan as “cautious”, stating that it “frustrat[es] hopes for tighter policy that would drive the nation to peak carbon emissions well before president Xi Jinping’s 2030 deadline”. Carbon Brief has just published an in-depth analysis of the plan. China Daily reported that the strategy “highlights measures to promote the climate targets of peaking carbon dioxide emissions before 2030”, which China said it would work towards “actively yet prudently”.
Around the world
- EU RULES: The European Commission has proposed new “made in Europe” rules to support domestic low-carbon industries, “against fierce competition from China”, reported Agence France-Presse. Carbon Brief examined what it means for climate efforts.
- RECORD HEAT: The US National Oceanic and Atmospheric Administration has said there is a 50-60% chance that the El Niño weather pattern could return this year, amplifying the effect of global warming and potentially driving temperatures to “record highs”, according to Euronews.
- FLAGSHIP FUND: The African Development Bank’s “flagship clean energy fund” plans to more than double its financing to $2.5bn for African renewables over the next two years, reported the Associated Press.
- NO WITHDRAWAL: Vanuatu has defied US efforts to force the Pacific-island nation to drop a UN draft resolution calling on the world to implement a landmark International Court of Justice (ICJ) ruling on climate, according to the Guardian.

Captured
UK greenhouse gas emissions in 2025 fell to 54% below 1990 levels, the baseline year for its legally binding climate goals, according to new Carbon Brief analysis. Over the same period, data from the World Bank shows that the UK’s economy has expanded by 95%, meaning that emissions have been decoupling from growth.
Spotlight
Bristol’s ‘pioneering’ community wind turbine
Following the recent launch of the UK government’s local power plan, Carbon Brief visits one of the country’s community-energy success stories.
The Lawrence Weston housing estate is set apart from the main city of Bristol, wedged between the tree-lined grounds of a stately home and a sprawl of warehouses and waste incinerators. It is one of the most deprived areas in the city.
Yet, just across the M5 motorway stands a structure that has brought the spoils of the energy transition directly to this historically forgotten estate – a 4.2 megawatt (MW) wind turbine.
The turbine is owned by local charity Ambition Lawrence Weston and all the profits from its electricity sales – around £100,000 a year – go to the community. In the UK’s local power plan, it was singled out by energy secretary Ed Miliband as a “pioneering” project.
‘Sustainable income’
On a recent visit to the estate by Carbon Brief, Ambition Lawrence Weston’s development manager, Mark Pepper, rattled off the story behind the wind turbine.
In 2012, Pepper and his team were approached by the Bristol Energy Cooperative with a chance to get a slice of the income from a new solar farm. They jumped at the opportunity.
“Austerity measures were kicking in at the time,” Pepper told Carbon Brief. “We needed to generate an income. Our own, sustainable income.”
With the solar farm proving to be a success, the team started to explore other opportunities. This began a decade-long process that saw them navigate the Conservative government’s “ban” on onshore wind, raise £5.5m in funding and, ultimately, erect the turbine in 2023.
Today, the turbine generates electricity equivalent to Lawrence Weston’s 3,000 households and will save 87,600 tonnes of carbon dioxide (CO2) over its lifetime.
‘Climate by stealth’
Ambition Lawrence Weston’s hub is at the heart of the estate and the list of activities on offer is seemingly endless: birthday parties, kickboxing, a library, woodworking, help with employment and even a pop-up veterinary clinic. All supported, Pepper said, with the help of a steady income from community-owned energy.
The centre itself is kitted out with solar panels, heat pumps and electric-vehicle charging points, making it a living advertisement for the net-zero transition. Pepper noted that the organisation has also helped people with energy costs amid surging global gas prices.
Gesturing to the England flags dangling limply on lamp posts visible from the kitchen window, he said:
“There’s a bit of resentment around immigration and scarcity of materials and provision, so we’re trying to do our bit around community cohesion.”
This includes supper clubs and an interfaith grand iftar during the Muslim holy month of Ramadan.
Anti-immigration sentiment in the UK has often gone hand-in-hand with opposition to climate action. Right-wing politicians and media outlets promote the idea that net-zero policies will cost people a lot of money – and these ideas have cut through with the public.
Pepper told Carbon Brief he is sympathetic to people’s worries about costs and stressed that community energy is the perfect way to win people over:
“I think the only way you can change that is if, instead of being passive consumers…communities are like us and they’re generating an income to offset that.”
From the outset, Pepper stressed that “we weren’t that concerned about climate because we had other, bigger pressures”, adding:
“But, in time, we’ve delivered climate by stealth.”

The post DeBriefed 6 March 2026: Iran energy crisis | China climate plan | Bristol’s ‘pioneering’ wind turbine appeared first on Carbon Brief.
China’s leadership has published a draft of its 15th five-year plan setting the strategic direction for the nation out to 2030, including support for clean energy and energy security.
The plan sets a target to cut China’s “carbon intensity” by 17% over the five years from 2026-30, but also changes the basis for calculating this key climate metric.
The plan continues to signal support for China’s clean-energy buildout and, in general, contains no major departures from the country’s current approach to the energy transition.
The government reaffirms support for several clean-energy industries, ranging from solar and electric vehicles (EVs) through to hydrogen and “new-energy” storage.
The plan also emphasises China’s willingness to steer climate governance and be seen as a provider of “global public goods”, in the form of affordable clean-energy technologies.
However, while the document says it will “promote the peaking” of coal and oil use, it does not set out a timeline and continues to call for the “clean and efficient” use of coal.
This shows that tensions remain between China’s climate goals and its focus on energy security, leading some analysts to raise concerns about its carbon-cutting ambition.
Below, Carbon Brief outlines the key climate change and energy aspects of the plan, including targets for carbon intensity, non-fossil energy and forestry.
Note: this article is based on a draft published on 5 March and will be updated if any significant changes are made in the final version of the plan, due to be released at the close next week of the “two sessions” meeting taking place in Beijing.

What is China’s 15th five-year plan?
Five-year plans are one of the most important documents in China’s political system.
Addressing everything from economic strategy to climate policy, they outline the planned direction for China’s socio-economic development in a five-year period. The 15th five-year plan covers 2026-30.
These plans include several “main goals”. These are largely quantitative indicators that are seen as particularly important to achieve and which provide a foundation for subsequent policies during the five-year period.
The table below outlines some of the key “main goals” from the draft 15th five-year plan.
| Category | Indicator | Indicator in 2025 | Target by 2030 | Cumulative target over 2026-2030 | Characteristic |
|---|---|---|---|---|---|
| Economic development | Gross domestic product (GDP) growth (%) | 5 | Maintained within a reasonable range and proposed annually as appropriate. | Anticipatory | |
| ‘Green and low-carbon | Reduction in CO2 emissions per unit of GDP (%) | 17.7 | 17 | Binding | |
| Share of non-fossil energy in total energy consumption (%) | 21.7 | 25 | Binding | ||
| Security guarantee | Comprehensive energy production capacity (100m tonnes of standard coal equivalent) |
51.3 | 58 | Binding |

Since the 12th five-year plan, covering 2011-2015, these “main goals” have included energy intensity and carbon intensity as two of five key indicators for “green ecology”.
The previous five-year plan, which ran from 2021-2025, introduced the idea of an absolute “cap” on carbon dioxide (CO2) emissions, although it did not provide an explicit figure in the document. This has been subsequently addressed by a policy on the “dual-control of carbon” issued in 2024.
The latest plan removes the energy-intensity goal and elevates the carbon-intensity goal, but does not set an absolute cap on emissions (see below).
It covers the years until 2030, before which China has pledged to peak its carbon emissions. (Analysis for Carbon Brief found that emissions have been “flat or falling” since March 2024.)
The plans are released at the two sessions, an annual gathering of the National People’s Congress (NPC) and the Chinese People’s Political Consultative Conference (CPPCC). This year, it runs from 4-12 March.
The plans are often relatively high-level, with subsequent topic-specific five-year plans providing more concrete policy guidance.
Policymakers at the National Energy Agency (NEA) have indicated that in the coming years they will release five sector-specific plans for 2026-2030, covering topics such as the “new energy system”, electricity and renewable energy.
There may also be specific five-year plans covering carbon emissions and environmental protection, as well as the coal and nuclear sectors, according to analysts.
Other documents published during the two sessions include an annual government work report, which outlines key targets and policies for the year ahead.
The gathering is attended by thousands of deputies – delegates from across central and local governments, as well as Chinese Communist party members, members of other political parties, academics, industry leaders and other prominent figures.
What does the plan say about China’s climate action?
Achieving China’s climate targets will remain a key driver of the country’s policies in the next five years, according to the draft 15th five-year plan.
It lists the “acceleration” of China’s energy transition as a “major achievement” in the 14th five-year plan period (2021-2025), noting especially how clean-power capacity had overtaken fossil fuels.
The draft says China will “actively and steadily advance and achieve carbon peaking”, with policymakers continuing to strike a balance between building a “green economy” and ensuring stability.
Climate and environment continues to receive its own chapter in the plan. However, the framing and content of this chapter has shifted subtly compared with previous editions, as shown in the table below. For example, unlike previous plans, the first section of this chapter focuses on China’s goal to peak emissions.

The climate and environment chapter in the latest plan calls for China to “balance [economic] development and emission reduction” and “ensure the timely achievement of carbon peak targets”.
Under the plan, China will “continue to pursue” its established direction and objectives on climate, Prof Li Zheng, dean of the Tsinghua University Institute of Climate Change and Sustainable Development (ICCSD), tells Carbon Brief.
What is China’s new CO2 intensity target?
In the lead-up to the release of the plan, analysts were keenly watching for signals around China’s adoption of a system for the “dual-control of carbon”.
This would combine the existing targets for carbon intensity – the CO2 emissions per unit of GDP – with a new cap on China’s total carbon emissions. This would mark a dramatic step for the country, which has never before set itself a binding cap on total emissions.
Policymakers had said last year that this framework would come into effect during the 15th five-year plan period, replacing the previous system for the “dual-control of energy”.
However, the draft 15th five-year plan does not offer further details on when or how both parts of the dual-control of carbon system will be implemented. Instead, it continues to focus on carbon intensity targets alone.
Looking back at the previous five-year plan period, the latest document says China had achieved a carbon-intensity reduction of 17.7%, just shy of its 18% goal.
This is in contrast with calculations by Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air (CREA), which had suggested that China had only cut its carbon intensity by 12% over the past five years.
At the time it was set in 2021, the 18% target had been seen as achievable, with analysts telling Carbon Brief that they expected China to realise reductions of 20% or more.
However, the government had fallen behind on meeting the target.
Last year, ecology and environment minister Huang Runqiu attributed this to the Covid-19 pandemic, extreme weather and trade tensions. He said that China, nevertheless, remained “broadly” on track to meet its 2030 international climate pledge of reducing carbon intensity by more than 65% from 2005 levels.
Myllyvirta tells Carbon Brief that the newly reported figure showing a carbon-intensity reduction of 17.7% is likely due to an “opportunistic” methodological revision. The new methodology now includes industrial process emissions – such as cement and chemicals – as well as the energy sector.
(This is not the first time China has redefined a target, with regulators changing the methodology for energy intensity in 2023.)
For the next five years, the plan sets a target to reduce carbon intensity by 17%, slightly below the previous goal.
However, the change in methodology means that this leaves space for China’s overall emissions to rise by “3-6% over the next five years”, says Myllyvirta. In contrast, he adds that the original methodology would have required a 2% fall in absolute carbon emissions by 2030.
The dashed lines in the chart below show China’s targets for reducing carbon intensity during the 12th, 13th, 14th and 15th five-year periods, while the bars show what was achieved under the old (dark blue) and new (light blue) methodology.
The carbon-intensity target is the “clearest signal of Beijing’s climate ambition”, says Li Shuo, director at the Asia Society Policy Institute’s (ASPI) China climate hub.
It also links directly to China’s international pledge – made in 2021 – to cut its carbon intensity to more than 65% below 2005 levels by 2030.
To meet this pledge under the original carbon-intensity methodology, China would have needed to set a target of a 23% reduction within the 15th five-year plan period. However, the country’s more recent 2035 international climate pledge, released last year, did not include a carbon-intensity target.
As such, ASPI’s Li interprets the carbon-intensity target in the draft 15th five-year plan as a “quiet recalibration” that signals “how difficult the original 2030 goal has become”.
Furthermore, the 15th five-year plan does not set an absolute emissions cap.
This leaves “significant ambiguity” over China’s climate plans, says campaign group 350 in a press statement reacting to the draft plan. It explains:
“The plan was widely expected to mark a clearer transition from carbon-intensity targets toward absolute emissions reductions…[but instead] leaves significant ambiguity about how China will translate record renewable deployment into sustained emissions cuts.”
Myllyvirta tells Carbon Brief that this represents a “continuation” of the government’s focus on scaling up clean-energy supply while avoiding setting “strong measurable emission targets”.
He says that he would still expect to see absolute caps being set for power and industrial sectors covered by China’s emissions trading scheme (ETS). In addition, he thinks that an overall absolute emissions cap may still be published later in the five-year period.
Despite the fact that it has yet to be fully implemented, the switch from dual-control of energy to dual-control of carbon represents a “major policy evolution”, Ma Jun, director of the Institute of Public and Environmental Affairs (IPE), tells Carbon Brief. He says that it will allow China to “provide more flexibility for renewable energy expansion while tightening the net on fossil-fuel reliance”.
Does the plan encourage further clean-energy additions?
“How quickly carbon intensity is reduced largely depends on how much renewable energy can be supplied,” says Yao Zhe, global policy advisor at Greenpeace East Asia, in a statement.
The five-year plan continues to call for China’s development of a “new energy system that is clean, low-carbon, safe and efficient” by 2030, with continued additions of “wind, solar, hydro and nuclear power”.
In line with China’s international pledge, it sets a target for raising the share of non-fossil energy in total energy consumption to 25% by 2030, up from just under 21.7% in 2025.
The development of “green factories” and “zero-carbon [industrial] parks” has been central to many local governments’ strategies for meeting the non-fossil energy target, according to industry news outlet BJX News. A call to build more of these zero-carbon industrial parks is listed in the five-year plan.
Prof Pan Jiahua, dean of Beijing University of Technology’s Institute of Ecological Civilization, tells Carbon Brief that expanding demand for clean energy through mechanisms such as “green factories” represents an increasingly “bottom-up” and “market-oriented” approach to the energy transition, which will leave “no place for fossil fuels”.
He adds that he is “very much sure that China’s zero-carbon process is being accelerated and fossil fuels are being driven out of the market”, pointing to the rapid adoption of EVs.
The plan says that China will aim to double “non-fossil energy” in 10 years – although it does not clarify whether this means their installed capacity or electricity generation, or what the exact starting year would be.
Research has shown that doubling wind and solar capacity in China between 2025-2035 would be “consistent” with aims to limit global warming to 2C.
While the language “certainly” pushes for greater additions of renewable energy, Yao tells Carbon Brief, it is too “opaque” to be a “direct indication” of the government’s plans for renewable additions.
She adds that “grid stability and healthy, orderly competition” is a higher priority for policymakers than guaranteeing a certain level of capacity additions.
China continues to place emphasis on the need for large-scale clean-energy “bases” and cross-regional power transmission.
The plan says China must develop “clean-energy bases…in the three northern regions” and “integrated hydro-wind-solar complexes” in south-west China.
It specifically encourages construction of “large-scale wind and solar” power bases in desert regions “primarily” for cross-regional power transmission, as well as “major hydropower” projects, including the Yarlung Tsangpo dam in Tibet.
As such, the country should construct “power-transmission corridors” with the capacity to send 420 gigawatts (GW) of electricity from clean-energy bases in western provinces to energy-hungry eastern provinces by 2030, the plan says.
State Grid, China’s largest grid operator, plans to install “another 15 ultra-high voltage [UHV] transmission lines” by 2030, reports Reuters, up from the 45 UHV lines built by last year.
Below are two maps illustrating the interlinkages between clean-energy bases in China in the 15th (top) and 14th (bottom) five-year plan periods.
The yellow dotted areas represent clean energy bases, while the arrows represent cross-regional power transmission. The blue wind-turbine icons represent offshore windfarms and the red cooling tower icons represent coastal nuclear plants.
The 15th five-year plan map shows a consistent approach to the 2021-2025 period. As well as power being transmitted from west to east, China plans for more power to be sent to southern provinces from clean-energy bases in the north-west, while clean-energy bases in the north-east supply China’s eastern coast.
It also maps out “mutual assistance” schemes for power grids in neighbouring provinces.
Offshore wind power should reach 100GW by 2030, while nuclear power should rise to 110GW, according to the plan.
What does the plan signal about coal?
The increased emphasis on grid infrastructure in the draft 15th five-year plan reflects growing concerns from energy planning officials around ensuring China’s energy supply.
Ren Yuzhi, director of the NEA’s development and planning department, wrote ahead of the plan’s release that the “continuous expansion” of China’s energy system has “dramatically increased its complexity”.
He said the NEA felt there was an “urgent need” to enhance the “secure and reliable” replacement of fossil-fuel power with new energy sources, as well as to ensure the system’s “ability to absorb them”.
Meanwhile, broader concerns around energy security have heightened calls for coal capacity to remain in the system as a “ballast stone”.
The plan continues to support the “clean and efficient utilisation of fossil fuels” and does not mention either a cap or peaking timeline for coal consumption.
Xi had previously told fellow world leaders that China would “strictly control” coal-fired power and phase down coal consumption in the 15th five-year plan period.
The “geopolitical situation is increasing energy security concerns” at all levels of government, said the Institute for Global Decarbonization Progress in a note responding to the draft plan, adding that this was creating “uncertainty over coal reduction”.
Ahead of its publication, there were questions around whether the plan would set a peaking deadline for oil and coal. An article posted by state news agency Xinhua last month, examining recommendations for the plan from top policymakers, stated that coal consumption would plateau from “around 2027”, while oil would peak “around 2026”.
However, the plan does not lay out exact years by which the two fossil fuels should peak, only saying that China will “promote the peaking of coal and oil consumption”.
There are similarly no mentions of phasing out coal in general, in line with existing policy.
Nevertheless, there is a heavy emphasis on retrofitting coal-fired power plants. The plan calls for the establishment of “demonstration projects” for coal-plant retrofitting, such as through co-firing with biomass or “green ammonia”.
Such retrofitting could incentivise lower utilisation of coal plants – and thus lower emissions – if they are used to flexibly meet peaks in demand and to cover gaps in clean-energy output, instead of providing a steady and significant share of generation.
The plan also calls for officials to “fully implement low-carbon retrofitting projects for coal-chemical industries”, which have been a notable source of emissions growth in the past year.
However, the coal-chemicals sector will likely remain a key source of demand for China’s coal mining industry, with coal-to-oil and coal-to-gas bases listed as a “key area” for enhancing the country’s “security capabilities”.
Meanwhile, coal-fired boilers and industrial kilns in the paper industry, food processing and textiles should be replaced with “clean” alternatives to the equivalent of 30m tonnes of coal consumption per year, it says.
“China continues to scale up clean energy at an extraordinary pace, but the plan still avoids committing to strong measurable constraints on emissions or fossil fuel use”, says Joseph Dellatte, head of energy and climate studies at the Institut Montaigne. He adds:
“The logic remains supply-driven: deploy massive amounts of clean energy and assume emissions will eventually decline.”
How will China approach global climate governance in the next five years?
Meanwhile, clean-energy technologies continue to play a role in upgrading China’s economy, with several “new energy” sectors listed as key to its industrial policy.
Named sectors include smart EVs, “new solar cells”, new-energy storage, hydrogen and nuclear fusion energy.
“China’s clean-technology development – rather than traditional administrative climate controls – is increasingly becoming the primary driver of emissions reduction,” says ASPI’s Li. He adds that strengthening China’s clean-energy sectors means “more closely aligning Beijing’s economic ambitions with its climate objectives”.
Analysis for Carbon Brief shows that clean energy drove more than a third of China’s GDP growth in 2025, representing around 11% of China’s whole economy.
The continued support for these sectors in the draft five-year plan comes as the EU outlined its own measures intended to limit China’s hold on clean-energy industries, driven by accusations of “unfair competition” from Chinese firms.
China is unlikely to crack down on clean-tech production capacity, Dr Rebecca Nadin, director of the Centre for Geopolitics of Change at ODI Global, tells Carbon Brief. She says:
“Beijing is treating overcapacity in solar and smart EVs as a strategic choice, not a policy error…and is prepared to pour investment into these sectors to cement global market share, jobs and technological leverage.”
Dellatte echoes these comments, noting that it is “striking” that the plan “barely addresses the issue of industrial overcapacity in clean technologies”, with the focus firmly on “scaling production and deployment”.
At the same time, China is actively positioning itself to be a prominent voice in climate diplomacy and a champion of proactive climate action.
This is clear from the first line in a section on providing “global public goods”. It says:
“As a responsible major country, China will play a more active role in addressing global challenges such as climate change.”
The plan notes that China will “actively participate in and steer [引领] global climate governance”, in line with the principle of “common,but differentiated responsibilities”.
This echoes similar language from last year’s government work report, Yao tells Carbon Brief, demonstrating a “clear willingness” to guide global negotiations. But she notes that this “remains an aspiration that’s yet to be made concrete”. She adds:
“China has always favored collective leadership, so its vision of leadership is never a lone one.”
The country will “deepen south-south cooperation on climate change”, the plan says. In an earlier section on “opening up”, it also notes that China will explore “new avenues for collaboration in green development” with global partners as part of its “Belt and Road Initiative”.
China is “doubling down” on a narrative that it is a “responsible major power” and “champion of south-south climate cooperation”, Nadin says, such as by “presenting its clean‑tech exports and finance as global public goods”. She says:
“China will arrive at future COPs casting itself as the indispensable climate leader for the global south…even though its new five‑year plan still puts growth, energy security and coal ahead of faster emissions cuts at home.”
What else does the plan cover?
The impact of extreme weather – particularly floods – remains a key concern in the plan.
China must “refine” its climate adaptation framework and “enhance its resilience to climate change, particularly extreme-weather events”, it says.
China also aims to “strengthen construction of a national water network” over the next five years in order to help prevent floods and droughts.
An article published a few days before the plan in the state-run newspaper China Daily noted that, “as global warming intensifies, extreme weather events – including torrential rains, severe convective storms, and typhoons – have become more frequent, widespread and severe”.
The plan also touches on critical minerals used for low-carbon technologies. These will likely remain a geopolitical flashpoint, with China saying it will focus during the next five years on “intensifying” exploration and “establishing” a reserve for critical minerals. This reserve will focus on “scarce” energy minerals and critical minerals, as well as other “advantageous mineral resources”.
Dellatte says that this could mean the “competition in the energy transition will increasingly be about control over mineral supply chains”.
Other low-carbon policies listed in the five-year plan include expanding coverage of China’s mandatory carbon market and further developing its voluntary carbon market.
China will “strengthen monitoring and control” of non-CO2 greenhouse gases, the plan says, as well as implementing projects “targeting methane, nitrous oxide and hydrofluorocarbons” in sectors such as coal mining, agriculture and chemicals.
This will create “capacity” for reducing emissions by 30m tonnes of CO2 equivalent, it adds.
Meanwhile, China will develop rules for carbon footprint accounting and push for internationally recognised accounting standards.
It will enhance reform of power markets over the next five years and improve the trading mechanism for green electricity certificates.
It will also “promote” adoption of low-carbon lifestyles and decarbonisation of transport, as well as working to advance electrification of freight and shipping.
