The UK government has set out an “action plan” for reaching its target of clean power by 2030, which it describes as “the most ambitious reforms to our energy system in generations”.
The plan outlines how the government hopes to “make Britain a clean energy superpower to cut bills, create jobs and deliver security with cheaper, zero-carbon electricity by 2030”.
This was one of five “missions” in the Labour manifesto, on which the government was elected with a landslide majority in July.
Following independent advice from the National Energy System Operator (NESO), the government is aiming for clean power to meet 100% of electricity demand by 2030, with at least 95% of electricity generation coming from low-carbon sources and no more than 5% from unabated gas.
The 136-page plan sees wind and solar – in particular offshore wind – becoming the backbone of the British electricity system. It says record amounts of new renewable capacity will need to be delivered, alongside reforms to the planning process and major grid enhancements.
While delivering all this would be a huge undertaking, the plan says it could unlock extra investments worth £40bn a year out to 2030, delivering “reindustrialisation”, jobs and lower bills.

Where the clean power 2030 target comes from
The Labour party fought the 2024 UK election campaign on a manifesto pledging to “make Britain a clean energy superpower…with cheaper, zero-carbon electricity by 2030”.
This was an advance on the previous Conservative government’s 2021 pledge to “fully decarbonise” the power system by 2035.
Both parties had identified the need for clean power in order to help decarbonise the rest of the UK economy, as heat and transport are increasingly electrified with heat pumps and electric vehicles.
However, the Labour party has explicitly tied its clean power “mission” not just to the UK’s climate goals, but to energy security and bills in the wake of the global energy crisis, as well as jobs.
In a press statement launching the report, secretary of state for energy and climate change Ed Miliband says:
“A new era of clean electricity for our country offers a positive vision of Britain’s future with energy security, lower bills, good jobs and climate action. This can only happen with big, bold change and that is why the government is embarking on the most ambitious reforms to our energy system in generations. ”
Just after taking office at the start of July 2024, Miliband reiterated his commitment to the clean power 2030 target when setting out his priorities for government.
He then appointed Chris Stark, the former chief executive of the Climate Change Committee, to head up a new “mission control” function within government, as well as informally asking NESO for independent advice on how to reach the clean power 2030 target.
(NESO was created as part of the Energy Act 2023, having already been hived off from National Grid. It was officially launched on 1 October 2024 as a new independent organisation responsible for planning the entire energy system in Britain, including operating the electricity network and offering “expert advice to the energy sector’s decision makers”.)
Speaking to UK Energy Research Centre (UKERC) director Prof Rob Gross on the Talking Energy podcast, NESO chief economist Mike Thompson said the body had begun working on its advice to government in July 2024, soon after the election result became clear.
The government had then formally requested NESO’s guidance in an August 2024 letter, which asked for “practical advice on achieving clean power by 2030”.
It asked for different pathways to reach this goal, as well as key requirements for electricity grids, high-level analysis of costs and benefits, and suggested actions to get on track.
The NESO advice, published on 5 November 2024, said the 2030 target was “achievable…without increasing costs” and that it would insulate the UK from “volatile international gas prices”.
A key element of the NESO advice was to offer a working definition of clean power by 2030.
It adopted a definition with two parts. It said clean power should cover 100% of electricity demand by 2030, in a year with average weather conditions. In addition, it said at least 95% of the electricity generated within the country’s borders should come from low-carbon sources, with up to 5% coming from unabated gas. This means the country would become a net electricity exporter.
(The national electricity grid – and the clean power 2030 target – technically only covers the island of Great Britain, whereas Northern Ireland is part of the separate all-Ireland network.)
Thompson explained on the Talking Energy podcast:
“We think that there should be enough clean power to cover all of GB demand over the year…But of course, a lot of that generation is coming from wind power, from solar, and you can’t control when it is outputting…So we adopted this definition that actually you cover all of demand [with clean power], but you would also allow up to no more than 5% of generation to come from unabated gas.”
The government formally adopted the NESO definition of clean power when prime minister Keir Starmer announced his milestones for delivering a “decade of national renewal”.
This definition, for clean power to meet 100% of demand in 2030 but only 95% of generation, was widely reported as a “watering down” of Labour’s manifesto pledge. A spokesperson for the Department of Energy Security and Net Zero said this was “categorically untrue”.
Labour’s manifesto had not defined its clean power by 2030 target and had made clear reference to a “strategic reserve of gas power”.
An earlier Labour policy document had said that the country would “run on 100% clean…power”, which is consistent with the government’s target for clean power to meet 100% of demand.
What clean power 2030 will look like
The government’s action plan accepts the NESO advice as its starting point.
While NESO offered two different pathways to clean power in 2030, they share many of the same features, with wind and solar making up the largest share of electricity in both cases.
In 2023, fossil fuels made up a third of electricity generation in the country, with wind and solar making up another third, and the remainder coming from nuclear, biomass and imports.
By 2030, if the clean power target is met, unabated fossil fuels would make up less than 5% of generation, with wind and solar making up around 80% of the mix, as shown in the figure below.
Offshore wind would form the backbone of the GB electricity mix in 2030, meeting around half of demand under either the NESO “new dispatch” scenario or under “further flex and renewables”.
The difference between the two NESO pathways lies in the way that they manage gaps in the output of variable wind and solar power.
The “new dispatch” pathway relies more on low-carbon “dispatchable” power, meaning capacity that can be turned on and off at will. This includes gas-fired power stations fitted with carbon capture and storage (CCS), or turbines that burn low-carbon hydrogen fuel.
The “further flex and renewables” pathway relies on larger amounts of wind and solar capacity, coupled with a more flexible grid and higher levels of battery or long-duration energy storage.
The government’s action plan targets a range of clean power capacity by 2030 that would leave the door open to pursuing either of these scenarios, shown in the table below.
Crucially, the plan relies on keeping almost all of the country’s existing gas-fired power stations open for the rest of the decade, to help bridge those gaps in wind and solar output, until alternative low-carbon sources of flexibility become more widely available.
Thompson told the Talking Energy podcast:
“You keep something like a fleet around the size of the current gas fleet open [in 2030], but it would operate much, much less.”
While the existing gas fleet remains in place, the government will need to rapidly expand the amount of clean power capacity available to meet the 2030 target.
The action plan says the long timelines for new offshore wind projects mean there will only be time to bring forward schemes that are already or at least part-way through the planning process.
It also means that the next two “contracts for difference” (CfD) auctions, due to be held in 2025 and 2026, will need to secure the bulk of the offshore wind capacity required for 2030.
The UK currently has 15 gigawatts (GW) of offshore wind capacity, with another 16GW under construction or firmly committed. To meet the level required for clean power by 2030, the plan says that this would need to expand by at least another 12GW by 2030.
Similarly, at least an additional 8GW of onshore wind and 22GW of solar would be needed.
The Financial Times quoted a “government figure” saying that next year’s auction will need to be “huge” and the biggest ever for the country:
“When you think about the long lead times for a project like an offshore wind farm it makes sense to get going with the CfDs now and throw the book at this with a huge auction round as soon as possible, probably next year…It would be the biggest we’ve seen so far.”
In addition to building that new capacity, the plan relies on significantly enhancing the electricity transmission grid that sends power around the country, reforming the planning system so that new infrastructure can be built and ensuring the supply chains and workers are in place to deliver.
In a foreword to the action plan, Stark says the wider economic benefits of meeting the target are a “prize” worth around £40bn in investment every year until 2030.
The plan describes this as “once-in-a-generation levels of energy investment” that will “spread…the economic benefits of clean energy investment throughout the UK”. It adds:
“These investments will protect electricity consumers from volatile gas prices and be the foundation of a UK energy system that can bring down consumer bills for good. Every choice we make will be scrutinised to maximise the impact it can have in reducing consumer bills.”
The plan says that the clean power plan will “provide…the foundation to build an energy system that can bring down bills for households and businesses for good.” It adds:
“In their advice, NESO set out their analysis of potential impacts of delivering clean power on electricity costs in 2030. This indicated it could be delivered with similar costs to today, with scope for lower electricity costs and bills by 2030 as wider changes are taken into account.”
Ahead of the general election, Labour had promised that its clean power plan would cut energy bills by up to £300. The opposition Conservatives have disputed this.
On the question of how it would be possible to reduce bills while building large amounts of new infrastructure, UKERC’s Gross explained on the Talking Energy podcast that instead of spending large amounts on imported fossil fuels that are burned to generate electricity, billpayers would be investing in new clean power capacity, which would be paid back over many years.
How the government plans to reach clean power 2030
Achieving the clean power 2030 target would be a major undertaking. The government’s action plan sets out its approach to delivering this across a series of key areas.
Actions include reforming and expanding the government’s auctions for new clean power capacity, significantly expanding the country’s electricity grid and speeding up the process of connecting new projects, changing the planning system so that all this new infrastructure can be consented and built, and ensuring a supply chain with skilled workers is in place to deliver it.
Grid enhancement
The action plan outlines steps to expand and improve the electricity grid, saying that a failure to strengthen it "risks holding back our energy security, economic growth and other important infrastructure with lengthy delays”.
For example, it notes that, if no action is taken to address the annual “constraint costs” caused when networks are unable to carry all of the clean power being generated to where it is needed, then those costs are projected to increase from the “already high level” of £2bn per year in 2022 to around £8bn per year (or £80 per household) by the late 2020s.
An “unprecedented expansion” is therefore needed to deliver decarbonisation, energy security and affordability, with around twice as much new transmission infrastructure needed by 2030 as has been delivered in the past decade.
To enable this, the plan sets out several key actions, including reforming the connections process, reforming regulations, improving planning and consenting, and engaging with communities.
In the last five years, the grid “connection queue” of projects waiting to hook up to the electricity network has grown tenfold. Many of the projects within the queue are speculative or do not necessarily have the funding or planning permissions to progress, the action plan notes.
It says this means that fundamental reform is needed. Work has already begun on this. For example, in November the government, together with energy regulator Ofgem, outlined a series of changes in a joint letter that would fast-track renewable, clean power and storage projects.
The action plan includes further reform to the current “first come, first served” process for the queue. The government says it will go beyond previous plans to simply remove slow or stalled projects from the queue and prioritise readiness alone.
It will now also consider technological and locational factors, remove unviable projects, re-order the queue and accelerate connection timescales, the action plan states.
In a foreword to the plan, Miliband says:
“Ultimately, we need to move fast and build things to deliver the once-in-a-generation upgrade of our energy infrastructure Britain needs.”
Following consultations with Ofgem, NESO and network companies, there are now detailed methodologies for filtering the queue and prioritising connections for strategically important plans.
These changes will take into account recommendations from both electricity networks commissioner Nick Winser’s report in 2023 – which set out recommendations to halve the connection times of projects – and NESO’s Clean Power 2030 advice, which confirmed the need for 80 new transmission grid projects to be built, if the target is to be achieved.
Additionally, the action plan notes that, wherever renewable projects can be connected to the lower-voltage local distribution systems, instead of the high-voltage national transmission grid – known as the motorways of the electricity network – this should be encouraged.
(Projects that have secured a CfD or “capacity market” contract, “nationally significant” projects and others that are considered well advanced will be included in the reformed connections queue, according to the plan.)
Beyond the connections queue, the action plan sets out regulatory reforms to support clean power by 2030. This includes amending the Strategy and Policy Statement, wherein the government’s strategic priorities for energy policy are outlined, to ensure that 2030 clean power and decarbonisation more broadly are weighted in decision making.
The government will also work with Ofgem to explore the appropriateness of tightening incentives and penalties for network operators, for the delivery of strategically important infrastructure.
To accelerate the build out of both transmission and distribution networks required for the 2030 target, planning system changes will be required. (See: Planning reforms.)
Currently, it can take between two to four years to gain land rights in England and Wales, which can “lead to unnecessary delays”, the action plan notes.
To address these processes, the action plan says that planning consent exemptions will be expanded to include low-voltage connections and upgrades.
There are also further opportunities to provide flexibilities on the consenting of electricity substations, it adds.
The final core part of action on the grid, outlined in the plan, focuses on community engagement, as “this government believes that it is a vital principle that communities that host clean energy infrastructure should benefit from it”.
This will include publishing voluntary guidance to increase the amount and consistency of community benefit funds from transmissions networks. There will also be support for the launch of a public communications campaign around grid expansion, the plan says.
Planning reforms
Since the election in July, the Labour government has taken several steps to help transition the electricity system towards net-zero.
This includes lifting the de-facto ban on onshore wind in England, which had been in place since 2015, within weeks of taking office.
Labour also approved three large solar farms in its first few weeks in government. In total, these sites – Gate Burton in Lincolnshire, Mallard Pass in Lincolnshire and Sunnica in Suffolk and Cambridgeshire – have a capacity of over 1.3GW.
Given their size, all three solar sites are considered nationally significant infrastructure projects (NSIPs), and as such require a development consent order from the energy secretary, as opposed to planning permission from the local planning authority.
One day before the action plan was released, the government published its response to a consultation on proposed changes to the National Planning Policy Framework (NPPF).
This includes plans to bring onshore wind back under the NSIP regime, in line with other types of major infrastructure. It also intends to raise the threshold above which onshore wind and solar projects will need central government NSIP consent to 100 megawatts (MW).
The government is planning to introduce legislation in the spring of 2025 to bring in these changes.
The action plan builds on these changes in an effort to improve the planning process.
It states that the planning system is “not working at the pace required” to meet the 2030 target and that this “urgent need for change” necessitates “a wide-ranging reform programme”.
To enable clean power by 2030, most new transmission grid and offshore wind projects will need all relevant planning permissions to be in place by 2026, the report notes.
While onshore wind, solar and battery energy storage projects have shorter construction timelines, they will still likely need to have received planning consent by 2028.
The report states that the government has identified pathways for delivery for “firm” generation – such as nuclear – as well as for sources of low-carbon flexibility, but does not give a date by which they must be consented.
Other changes outlined in the report include equipping organisations such as the Planning Inspectorate, statutory consultees such as the Environment Agency, local planning authorities and government consenting teams, with the “tools they need” to make decisions faster.
The report highlights that, in 2023-24, more than 60% of delayed responses to planning applications from the Environment Agency were due to resourcing constraints, and for nature regulator Natural England it was more than 80%.
It promises changes including boosting local planning capacity, expanding cost-recovery mechanisms – which see developers pay for the work needed to give them planning consent – and longer-term reforms. In particular, the changes will allow them to “better flex and prioritise their resources” so that “mission-critical projects” can be processed faster, it says.
The action plan includes updating “national policy statements” (NPSs) for energy and planning policy guidance in 2025, along with the changes to the NPPF already announced.
A programme of legislative reform will be undertaken by the government, including through the Planning and Infrastructure Bill, which will be brought forward next year. This will include NPSs being updated every five years, through a “quicker and easier process”.
Further reforms to the NSIP planning system in England and Wales will be undertaken, as well as changes to infrastructure consenting in Scotland.
(There is executive devolution in Scotland with regards to the infrastructure planning system, however under the Electricity Act, reserved to Westminster, the UK government will be able to bring in changes to deliver a “streamlined and efficient framework”, the plan says.)
The report highlights the importance of a coordinated approach to planning and notes that, to support this, NESO will deliver a “strategic spatial energy plan” in 2026, setting out a long-term approach to planning to deliver net-zero by 2050.
Under the NSIP process, the government will undertake a review of the lawfulness of challenges to development consent for major infrastructure. While judicial review is a “constitutionally important mechanism”, the action plan notes, most are unsuccessful and can take many years, significantly delaying new infrastructure and increasing costs to consumers.
As such, the plan includes a commitment to reform the judicial review process for NSIPs, following the Banner report on why such legal challenges arise.
Additional actions announced within the plan include changes to ensure communities can directly benefit from the clean energy infrastructure they host.
It notes that locally-consented energy infrastructure can take up to 12 months to receive a decision on a planning application, despite a four-month limit on projects that require an environmental impact assessment
Finally, the plan says that, by delivering a “marine recovery fund” for offshore wind, as well as using development to fund nature recovery, the government will look to use the action plan to protect nature and ensure that it is embedded in the transition to clean power by 2030.
Renewable energy auctions
The action plan announces further changes to the CfD support scheme for new renewable energy.
This follows action by the current government earlier in the year to bolster the sixth CfD auction, including increasing its budget by over 50% from the level set in March under the previous Conservative government to £1.56bn.
(The previous fifth auction, held in 2023, had not secured any new offshore wind.)
This year’s sixth auction contracted more than 130 new wind, solar and tidal energy projects, amounting to 9.6GW of capacity. Still, some cautioned at the time that a “big step-up” would still be required if the power sector is to be decarbonised by the end of the decade.
The government is introducing a number of changes to the CfDs ahead of the seventh auction, due to be held in 2025. This includes allowing onshore wind farms that are “repowering” – meaning replacing old turbines as they retire with newer models – an extension to the “phasing” process for floating offshore wind and streamlining the appeals process to take place ahead of the auction.
There is currently around 31GW of offshore wind built, under construction or contracted. However, this needs to rise to 43-50GW in 2030. (See: What clean power 2030 will look like).
The government will therefore aim to secure at least 12GW of new projects over the next two allocation rounds. To enable this, the action plan sets out further reform to the CfD process.
Changes will include a relaxation of the CfD eligibility criteria for fixed-bottom offshore wind projects to allow projects to bid even if they have not obtained full planning consent.
To avoid a repeat of the fifth auction, there will also be changes to the information the secretary of state uses to inform the final budget for fixed-bottom offshore wind.
There will also be a review of auction parameters, following “industry concerns” around the way the notional “budget” of each round is calculated.
(The “budget” for each auction round is an artificial construct, set by the government and designed to limit the impact of CfDs on consumer bills. Any support for CfD projects is paid for by billpayers rather than from government budgets. Moreover, a larger “budget” may not translate into higher bills, because CfD projects also push down wholesale electricity prices.)
Specifically, the government will look at the “reference price” against which each new CfD scheme is valued. Recent auction rounds have used very low reference prices, which inflate the notional budget impact of new projects, even if they are likely to lower consumer costs.
The government is also considering changes to the CfD contract terms to give longer market security, once the contracts are awarded. This could see the length of the contracts increased from the current 15-year standard term.
Consultations will take place in early 2025, ahead of the seventh allocation round, with a view to implementing them in the summer of 2025.
Beyond the CfD reforms, the action plan includes a number of commitments to improve renewable energy project delivery. These include facilitating greater coordination between wind turbines, civil aviation and defence infrastructure.
Further detail on Great British Energy’s (GBE) project development is included, including promises that the state-owned energy company – a core part of the Labour manifesto – will align its projects on private land with NESOs location suggestions, and develop further projects on public land.
The action plan states that GBE will provide support to deliver the Local Power Plan, to put “local authorities and communities at the heart of restructuring our energy economy”. Additional work will be done to support the deployment of rooftop solar, assess the potential of solar “canopies” on outdoor carparks and support programmes such as the Warm Homes Local Grant.
First introduced in 2002, the UK-wide renewables obligation (RO) scheme currently supports around 30% of the UK’s electricity supply. From 2027, it will start to come to an end, with around 9GW of capacity reaching the end of the subsidy by December 2030.
The action plan commits the government to conduct further analysis to inform the possible policy options needed to manage the risk that RO-supported projects might stop operating.
For the work being undertaken on renewables and nuclear, the action plan includes a list of key upcoming milestones, including:
- Spring 2025: Solar Roadmap and the Onshore Wind Industry Taskforce report.
- Early 2025: Consultation on relevant reforms to the CfD scheme.
- “In due course”: Consultation response on the Future Homes and Buildings Standards.
- After the spending review: Further details on the Warm Homes Plan.
- In 2025: A call for evidence on the potential to drive solar canopies on carparks.
- “In due course”: Consultation response on transitional support for large-scale biomass.
Flexibility and ‘dispatchable’ clean power
Beyond renewables, the plan includes a number of actions to reform the electricity market to support energy security, through flexibility and “dispatchable” power.
As with the other core areas, the government has taken a number of actions in its first six months to support this, including signing the contracts for the first gas CCS project in the UK.
French utility firm EDF has also announced plans to keep four existing nuclear power stations open for longer, meaning 4.6GW of nuclear capacity will remain on the grid in 2030.
The action plan includes support for investor certainty through wholesale electricity market reforms, reforming the capacity market and accelerating reforms to the balancing markets through which supply and demand are matched in real time, which it says will help unlock consumer-led flexibility. It notes:
“While the state must play a role as system architect, markets are, and will remain, central to the development, delivery, and operation of the power system.”
The action plan promises to set a clear “direction of travel” for wholesale market reform. As part of this, it is continuing to conduct further analysis as part of the long-running review of electricity market arrangements (REMA), which began in 2022 under the previous government. The action plan says that its work so far has made clear that “no change” is not an option.
The government says it will conclude the REMA process by “around mid-2025”, including whether to bring in “zonal pricing” or whether electricity prices will continue to be set at national level.
Currently, Britain uses a national pricing system whereby generators are paid the same regardless of where they are. Zonal pricing is a form of “locational pricing” that would see the country divided into zones, in an effort to reduce grid constraints and energy costs.
In order to avoid any changes affecting the investment needed in new clean power capacity, the government pledges to “align” the process with the next CfD auction. It also flags the potential for “transitional or legacy arrangements” that could protect existing investments from future changes:
“We plan, therefore, to announce the final decisions on REMA and the timetable for their implementation, particularly in relation to wholesale market reform and any transitional or legacy arrangements, before the AR7 auctions open, giving investors clarity for prospective bids.”
Other actions include NESO promising an electricity system operability strategy for 2030, improved forecasting of medium to long-term grid operability needs and improved emissions reporting from NESO across all electricity markets.
To support greater flexibility in the electricity system, the government plans to publish a “low carbon flexibility roadmap” in 2025. This will consolidate existing and future actions to drive short and long-duration flexibility.
Currently, there is 4.5GW of battery storage in Great Britain, the majority of which is grid-scale assets. By 2030, 23-27GW of battery storage is expected to be needed to meet the demands of a clean power system.
The action plan includes specific measures to overcome “hurdles” in the rollout of battery storage, such as working with Ofgem to ease network connections. (See: Grid enhancement.)
It says it will bring in incremental market reforms to provide batteries and consumer-led flexibility with access to relevant markets. This could include, for example, households shifting demand from electric vehicle charging at home, to use abundant renewable generation late at night instead of during peak hours when the grid is strained.
To support this, the action plan suggests enhancing rewards for consumers who choose to participate in flexibility, as well as the need for changes to market access for flexibility providers and support for the rollout of smart appliances.
Finally, work will be undertaken to enable portfolios of projects and activities to deliver consumer-led flexibility. Among other things, this builds on the rollout of the demand flexibility mechanism, whereby households are paid to reduce energy consumption during tight periods.
The action plan identifies the need for further long-duration flexibility technologies and announces support for the development of a hydrogen power business model to derisk investment and speed up the rate of deployment.
Additionally, Ofgem will introduce a “cap and floor scheme” to support investment in long-duration electricity storage. It says it is aiming to publish an open letter on specific aspects of the scheme soon, and in the first quarter of next year, DESNZ and Ofgem will publish the technical decisions undertaken to provide clarity on any outstanding areas of its design.
NESO has agreed to provide further advice as to the range of technologies needed. The scheme is expected to open to applications in the second quarter of next year.
The post Analysis: How the UK plans to reach clean power by 2030 appeared first on Carbon Brief.
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.
