Key developments
Critical mineral ‘deal’
TRANSITION TURMOIL: US president Donald Trump said China and the US reached a “deal” after talks were held in London, reported the BBC News, adding that “he said China had agreed to supply US companies with magnets and rare earth metals”. Shortly after the announcement, a Chinese manufacturer confirmed that it received “export permits” to countries including the US, according to Bloomberg. China’s earlier move to impose export curbs on critical minerals had “hit” the global auto industry, said Reuters. In answering Carbon Brief’s question of how the recent mineral disputes may affect global energy transition, Tian Jietang, director-general of the research department of industrial economy at the Development Research Center of the State Council said that the minerals are a “very important factor” for “new energy” development, but the “reason” behind the turmoil is “not from China”. China is “always open” to cooperate with the world for “faster green transition”, he added at an Asia House event.
‘FIRM’ CLIMATE ‘ACTIVIST’: Tian emphasised that China has always been a staunch contributor to global “green transition”. A similar line appeared in a comment article in the Communist party-affiliated newspaper People’s Daily, which called China a “firm activist and important contributor to the world’s green development”. In another People’s Daily article, the newspaper explained that the “direct reason” behind China’s “insist[ence] on carbon reduction” is that “climate warming threatens human survival and the continuation of civilisation”. It added that such “green and low-carbon transition” is also good for China’s economy and society. China Daily said the US’s tariffs on “clean energy products”, on the contrary, are “negatively affecting both [the] US and global green energy”.
Renewable pricing shift
MARKET PRICE: China entered a ”new stage of market-based pricing” for renewables on 1 June, after a notification was issued earlier this year, reported local newspaper Beijing Daily. The newspaper said projects that started operating before June would be paid prices pegged to the local coal-fired electricity price, in line with the previous policy, whereas electricity prices from projects operating after June will not be “protected”. (See the Carbon Brief explainer on the new policy.) The Shanghai-based Paper said there had been a rush to complete renewable projects before the June deadline – new installations of solar in April alone soared by 215%. As of April, the total capacity of wind and solar reached 1,530 gigawatts (GW) in China, “surpassing” the capacity of thermal power, reported industry news outlet BJX News. However, some wind and solar projects have been halted as a result of the new policy, said financial publication Yicai. The outlet quoted an unnamed source saying the returns for some projects are “no longer economically feasible”.

‘NEW ELECTRICITY SYSTEM’: Meanwhile, the plans to construct the “first batch of pilot projects” for a “new electricity system” was announced, reported BJX News. It added that according to a notification from the National Energy Administration (NEA), the pilot projects will focus on seven areas, including building “smart microgrids” and “virtual power plants”, better connecting clean energy “bases” to the rest of the country and developing “next-generation coal power”. Quoting experts, China Energy Net said that the success in building such a new system lies in transferring the current system from a “single” network to an “‘adaptability-early warning’ planning paradigm” over the next 15th “five-year plan” period (2026-30). The new system should be dominated by renewable energy and respond to risks, such as extreme weather, added the outlet. The NEA confirmed that “speeding up” plans for renewable energy over the next five-year plan period is one of its work priorities for the second half of the year, according to BJX News.
More plans issued as industry and oil set to drop
NEW SYSTEMS: China is aiming to build a “national standardised system for responding to climate change”, covering mitigation and adaptation, reported state news agency Xinhua. In an official Q&A, the Ministry of Ecology and Environment (MEE) said that it led the drafting of the new system, issued jointly with 14 other departments. Separately, the Central Committee of the Communist party of China and the State Council said that China’s market-based approach to environmental issues, such as carbon dioxide (CO2) emissions trading, should be “basically complete” by 2027, reported BJX News. This will include stronger links between the national emissions trading system (ETS) and related markets for “CCERs” and “GECs”, the outlet said. (The steel, cement and aluminium industries are being consulted over joining China’s national emissions trading system, ETS, according to a screenshot of a policy document circulating on social media. The document is not public, but its existence has been confirmed to Carbon Brief by multiple sources.)
INDUSTRY EMISSIONS: Meanwhile, the “national standards for product carbon footprints” for nine products, including electrolytic aluminium, chemical fibres and plastic, have been established, said the People’s Daily. It is estimated that the total carbon dioxide (CO2) emissions from the industry sector could drop to 450m tonnes in 2060, down 95% from 2025, according to a joint report by the Tsinghua University, as well as Energy Foundation China and the Chinese Academy of Environmental Planning – a research institute under the MEE, reported China Science Daily.
FALLING OIL DEMAND: The overall demand for oil is set to decline in China, with the “faster adoption” of “new-energy vehicles” (NEVs) offsetting growth in other areas, reported state-run newspaper China Daily. The outlet added that NEVs and liquefied natural gas (LNG) heavy trucks played a “significant role” in reducing demand for “traditional fuels” in 2024. In addition, strong sales of electric trucks – boosted by government incentives – pushed down demand for diesel, which makes up over a quarter of Chinese oil demand, said Bloomberg. Another article by China Daily said that one incentive – the equipment trade-in policy – motivated more than 4m car trade-in applications between January and May 2025. It said more than half of applications in the first four months of the year were for NEVs. The total production and sales of NEV reached just under 6m units in the first five months of this year, a year-on-year increase of around 45%, reported Xinhua.
Extreme weather events
RAIN AND HEATWAVES: Yunnan province in southeast China was hit by “flash floods and mudslides” triggered by heavy rainfall, affecting around 5,000 residents, reported Reuters. Hunan province in the south also received pouring rain, which “seriously damaged” roads and power facilities, said state broadcaster CCTV. Heatwaves, in the meantime, swept northern China with temperatures in Hebei and Xinjiang province topping 40C, reported China National Emergency Broadcasting Center, a state-run media outlet. People’s Daily reported that the central government had allocated 45m yuan ($6.2m) of “natural disaster relief funds” to support flood control and disaster relief in Yunnan, a landslide in Tibet, and drought relief in Gansu and Ningxia.
11,000,000,000
The capacity of newly approved coal power plants in the first quarter of 2025 in watts – some 11 gigawatts (GW). This is 1GW more than the first six months of last year, according to a report from NGO Greenpeace, covered by Reuters. The newswire added that China had approved 289GW of new coal capacity over 2021-25 and that last year saw the first annual decline in approvals since 2021.

More than 100bn yuan poured into coal via ‘capacity payments’ in 2024
To date, there is no clear evidence that China’s coal “capacity payments” are helping coal-fired power plants to transfer into a “supporting role” with reduced output and emissions, according to a Carbon Brief guest post by Mingxin Zhang, coal researcher at Global Energy Monitor (GEM).
In the first year of the scheme, GEM finds that some 70-100% of China’s coal plants received payments totalling more than 100bn yuan ($14.8bn), boosting their revenues by around 5-8%.
In this issue, Carbon Brief highlights the key findings of the guest post. The full article is available on Carbon Brief’s website.
A ‘supporting’ role for coal
China rolled out a system of “capacity payments” in January 2024, with the aim of maintaining energy security while helping coal-fired power plants shift into a “supporting role”, alongside a growing share of variable renewables.
The mechanism essentially provides a monthly “standby” payment to eligible public coal plants, to help cover fixed operating costs during low production periods and to ensure that they are available to switch on during peak demand periods.
The national framework sets payment levels at either 30% or 50% of a benchmark coal plant’s total fixed costs, which was determined to be 330 yuan ($45.8) per kilowatt (kW).
To illustrate the mechanism’s impact, consider a 600 megawatt (MW) coal plant running at China’s 2024 average rates – operating for 4,628 hours a year and selling electricity at 0.452 yuan ($0.063) per kilowatt-hour (kWh).
If it receives a 30% capacity payment, roughly 59.4m yuan ($8.2m) would be added to its bank account, driving up the revenue by 4.7%. If the rate is at the 50% level, the bump rises to 7.9%.
Project year one
After one year of China’s programme, GEM’s analysis finds that, while the policy has contributed to coal power plant revenue, there is still little definitive evidence to show that it is helping coal plants reduce their operation, as intended.
Only 12 provincial governments – representing 38% of the country’s total operating coal capacity – have released lists of qualifying plants.
Based on the national policy’s payment levels and the 12 provincial recipient lists, the capacity payments in these provinces alone was more than 40bn yuan ($5.5bn).
Combining the total operating capacity and payment numbers from the 12 provinces that have published data with GEM’s most recent national capacity figures, the analysis estimates that the total national payout in 2024 was approximately 107bn yuan ($14.8bn).
(This figure is uncertain. Greater transparency would help clarify how the mechanism is functioning and its role in shaping the future of coal in China’s power system.)
Despite restrictions, most coal capacity is eligible
By cross-referencing provincial recipient lists with GEM’s Global Coal Plant Tracker (GCPT), it is possible to estimate the share of each province’s coal capacity receiving payments.
In almost all of the 12 provinces that published recipient lists, 70-100% of coal capacity is eligible for payments.
The programme said that only “compliant, public operating coal units” are eligible for the capacity payments and excluded three categories:
- “Captive” units, which exclusively serve specific industrial or commercial entities and operate independently from the public power grid;
- Units failing to meet energy efficiency, environmental performance, or operational flexibility standards;
- Units not compliant with the broader “national plan”, a criterion that is not further clarified in the guidelines.
In some cases, the scheme as implemented by individual provinces appears inconsistent with the eligibility criteria. For example, the Mancheng Mill power station in Hebei provides heat and power exclusively to a pulp and paper industrial park. This appears inconsistent with the “captive unit” exclusion.
Some newly built coal power plants and decades-old plants were also included. For example, Beihai Bebuwan power station Unit 4 in Guangxi began operating in March 2024 and was added to the recipient list in September 2024. Shenhua Panshan power station Units 1 and 2 in Tianjin began operating in 1994 and were retrofitted in 2023.
Finally, several provincial lists include smaller units, which may have limited ability to contribute to peak demand management. For example, five 57MW units from Shaoxing Binhai power station in Zhejiang were accredited for capacity payments.
Their actual contribution to evening peak load, when generation from solar and wind is low, is unclear from the list or other available provincial assessments.
More questions than answers?
There was only two months between the announcement of coal capacity payments and their implementation, leaving no time for pilot programmes or detailed feedback. This may help explain the ambiguities that have emerged during the provincial execution process.
Our analysis of the first year of the scheme suggests that provincial discretion has played a major role, with national criteria loosely applied in practice.
Moreover, there is no clear evidence to date that the mechanism has led to reduced coal utilisation hours, or significantly increased solar and wind generation.

Embracing the future, powering growth: An energy system renewed for China
Springer Nature
A book jointly written by oil major Shell and the Development Research Center of the State Council of China explored energy transition challenges and pathways in China. At the book’s launch event, attended by Carbon Brief, representatives from both organisations introduced the main arguments in the book, including challenges China faces in reaching its “dual-carbon” goals, its high reliance on coal and regional disparities between renewable energy resources and demands, as well as its commitment to reach carbon neutrality in just 30 years – a shorter timeline than most developed countries. The book outlines three “approaches” and five “supports”, including electrification, better carbon and electricity pricing, legal support and investing in energy storage, as well as other resources, such as hydrogen and nuclear.
A machine learning approach to carbon emissions prediction of the top eleven emitters by 2030 and their prospects for meeting Paris Agreement targets
Scientific Reports
China, India, Japan, Canada, South Korea and Indonesia are projected to miss their 2030 emissions reduction targets by “significant margins”, according to new research. The authors used a machine learning approach to analyse data from 1990-2023 from the 11 highest emitting countries. They found that Russia is on track to exceed its reduction targets, while Germany and the US will “fall slightly short”. Iran and Saudi Arabia are expected to increase emissions rather than reduce them, according to the study. The authors say that “emerging economies require international collaboration and investment to support low-carbon transitions”.

Permitting reform: A major key to cutting climate pollution
By Dana Nuccitelli, CCL Research Coordinator
Permitting reform has emerged as the biggest and most important clean energy and climate policy area in the 119th Congress (2025-2026).
To make sure every CCL volunteer understands the opportunities and challenges ahead, CCL Vice President of Government Affairs Jennifer Tyler and I recently provided two trainings about the basics of permitting reform and understanding the permitting reform landscape.
These first introductory trainings set the stage for the rest of an ongoing series, which will delve into the details of several key permitting reform topics that CCL is engaging on. Read on for a recap of the first two trainings and a preview of coming attractions.
Permitting reform basics
Before diving into the permitting reform deep end, we need to first understand the fundamentals of the topic: what is “permitting”? What problems are we trying to solve with permitting reform? Why is it a key climate solution?
In short, a permit is a legal authorization issued by a government agency (federal and/or state and/or local) that allows a specific activity or project to proceed under certain defined conditions. The permitting process ensures that public health, safety, and the environment are protected during the construction and operation of the project.
But the permitting process can take a long time, and in some cases it’s taking so long that it’s unduly slowing down the clean energy transition. “Permitting reform” seeks to make the process more efficient while still ensuring that public health, safety, and the environment are protected.
There are a lot of factors involved in the permitting reform process, including environmental laws, limitations on lawsuits, and measures to expedite the building of electrical transmission lines that are key for expanding the capacity of America’s aging electrical grid in order to allow us to connect more clean energy and meet our energy affordability and security and climate needs.
But if we can succeed in passing a good, comprehensive permitting reform package through Congress, it could unlock enough climate pollution reductions to offset what we lost from this year’s rollback of the Inflation Reduction Act’s clean energy investments. Permitting reform is the big climate policy in the current session of Congress.
Understanding the permitting reform landscape
In the second training of this series, we sought to understand the players and the politics in the permitting reform space, learn about the challenges involved, and explore CCL’s framework and approach for weighing in on this policy topic.
Permitting reform has split some traditional alliances along two differing theories about how to best address climate change. Some groups with a theory of change relying on using permitting and lawsuits to slow and stop fossil fuel infrastructure are least likely to be supportive of a permitting reform effort. Groups like CCL that recognize the importance of quickly building lots of clean, affordable energy infrastructure are more supportive of permitting reform measures.
The subject has created some strange bedfellows, because clean energy and fossil fuel companies and organizations all want efficient permitting for their projects, and hence all tend to support permitting reform. For CCL, the key question is whether a comprehensive permitting reform package will be a net benefit to clean energy or the climate — and that’s what we’re working toward.
The two major political parties also have different priorities when it comes to permitting reform. Republicans tend to view it through a lens of reducing government red tape, ensuring that laws and regulations are only used for their intended purpose, and achieving energy affordability and security. Democrats prioritize building clean energy faster to slow climate change, addressing energy affordability, and protecting legacy environmental laws and community engagement.
As we discussed in the training, there are a number of key concepts that will require compromise from both sides of the aisle in order to reach a durable bipartisan permitting reform agreement. We’ll delve into the details of these in these upcoming trainings:
The Challenge of Energy Affordability and Security
First, with support from CCL’s Electrification Action Team, on February 5 I’ll examine what’s behind rising electricity rates and energy insecurity in the U.S. and how we can solve these problems. Electrification is a key climate solution in the transition to clean energy sources. But electricity rates are rising fast and face surging demand from artificial intelligence data centers. Permitting reform can play a key role in addressing these challenges.
Transmission Reform and Key Messages
Insufficient electrical transmission capacity is acting as a bottleneck slowing down the deployment of new clean energy sources in the U.S. Reforming cumbersome transmission permitting processes could unlock billions of tons of avoided climate pollution while improving America’s energy security and affordability. In this training on March 5, Jenn and I will dive into the details of the key clean energy and climate solution that is transmission reform, and the key messages to use when lobbying our members of Congress.
Clean energy projects often encounter long, complex permitting steps that slow construction and raise costs. Practical permitting reforms can help ensure that good projects move forward faster while upholding environmental and community protections. In this training on March 19, Jenn and I will examine permitting reforms to build energy infrastructure faster, some associated tensions and compromises that they may involve, and key messages for congressional offices.
Presidents from both political parties have taken steps to interfere with the permitting of certain types of energy infrastructure that they oppose. These executive actions create uncertainty that inhibits the development of new energy sources in the United States. For this reason, ensuring fair permitting certainty is a key aspect of permitting reform that enjoys bipartisan support. In this training on April 2, Jenn and I will discuss how Congress can ensure certainty in a permitting reform package, and key messages for congressional offices.
Community Engagement and Key Messages
It’s important for energy project developers to engage local communities in order to address any local concerns and adverse impacts that may arise from new infrastructure projects. But it’s also important to strike a careful balance such that community input can be heard and addressed in a timely manner without excessively slowing new clean energy project timelines. In this training on May 7, Jenn and I will examine how community engagement may be addressed in the permitting reform process, and key messages for congressional offices.
We look forward to nerding out with you in these upcoming advanced and important permitting reform trainings!

DeBriefed 30 January 2026: Fire and ice; US formally exits Paris; Climate image faux pas
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Fire and ice
OZ HEAT: The ongoing heatwave in Australia reached record-high temperatures of almost 50C earlier this week, while authorities “urged caution as three forest fires burned out of control”, reported the Associated Press. Bloomberg said the Australian Open tennis tournament “rescheduled matches and activated extreme-heat protocols”. The Guardian reported that “the climate crisis has increased the frequency and severity of extreme weather events, including heatwaves and bushfires”.
WINTER STORM: Meanwhile, a severe winter storm swept across the south and east of the US and parts of Canada, causing “mass power outages and the cancellation of thousands of flights”, reported the Financial Times. More than 870,000 people across the country were without power and at least seven people died, according to BBC News.
COLD QUESTIONED: As the storm approached, climate-sceptic US president Donald Trump took to social media to ask facetiously: “Whatever happened to global warming???”, according to the Associated Press. There is currently significant debate among scientists about whether human-caused climate change is driving record cold extremes, as Carbon Brief has previously explained.
Around the world
- US EXIT: The US has formally left the Paris Agreement for the second time, one year after Trump announced the intention to exit, according to the Guardian. The New York Times reported that the US is “the only country in the world to abandon the international commitment to slow global warming”.
- WEAK PROPOSAL: Trump officials have delayed the repeal of the “endangerment finding” – a legal opinion that underpins federal climate rules in the US – due to “concerns the proposal is too weak to withstand a court challenge”, according to the Washington Post.
- DISCRIMINATION: A court in the Hague has ruled that the Dutch government “discriminated against people in one of its most vulnerable territories” by not helping them to adapt to climate change, reported the Guardian. The court ordered the Dutch government to set binding targets within 18 months to cut greenhouse gas emissions in line with the Paris Agreement, according to the Associated Press.
- WIND PACT: 10 European countries have agreed a “landmark pact” to “accelerate the rollout of offshore windfarms in the 2030s and build a power grid in the North Sea”, according to the Guardian.
- TRADE DEAL: India and the EU have agreed on the “mother of all trade deals”, which will save up to €4bn in import duty, reported the Hindustan Times. Reuters quoted EU officials saying that the landmark trade deal “will not trigger any changes” to the bloc’s carbon border adjustment mechanism.
- ‘TWO-TIER SYSTEM’: COP30 president André Corrêa do Lago believes that global cooperation should move to a “two-speed system, where new coalitions lead fast, practical action alongside the slower, consensus-based decision-making of the UN process”, according to a letter published on Tuesday, reported Climate Home News.
$2.3tn
The amount invested in “green tech” globally in 2025, marking a new record high, according to Bloomberg.

Captured
Sales of electric vehicles (EVs) overtook standard petrol cars in the EU for the first time in December 2025, according to new figures released by the European Automobile Manufacturers’ Association (ACEA) and covered by Carbon Brief. Registrations of “pure” battery EVs reached 217,898 – up 51% year-on-year from December 2024. Meanwhile, sales of standard petrol cars in the bloc fell 19% year-on-year, from 267,834 in December 2024 to 216,492 in December 2025, according to the analysis.

Looking at climate visuals
Carbon Brief’s Ayesha Tandon recently chaired a panel discussion at the launch of a new book focused on the impact of images used by the media to depict climate change.
When asked to describe an image that represents climate change, many people think of polar bears on melting ice or devastating droughts.
But do these common images – often repeated in the media – risk making climate change feel like a far-away problem from people in the global north? And could they perpetuate harmful stereotypes?
These are some of the questions addressed in a new book by Prof Saffron O’Neill, who researches the visual communication of climate change at the University of Exeter.
“The Visual Life of Climate Change” examines the impact of common images used to depict climate change – and how the use of different visuals might help to effect change.
At a launch event for her book in London, a panel of experts – moderated by Carbon Brief’s Ayesha Tandon – discussed some of the takeaways from the book and the “dos and don’ts” of climate imagery.
Power of an image
“This book is about what kind of work images are doing in the world, who has the power and whose voices are being marginalised,” O’Neill told the gathering of journalists and scientists assembled at the Frontline Club in central London for the launch event.
O’Neill opened by presenting a series of climate imagery case studies from her book. This included several examples of images that could be viewed as “disempowering”.
For example, to visualise climate change in small island nations, such as Tuvalu or Fiji, O’Neill said that photographers often “fly in” to capture images of “small children being vulnerable”. She lamented that this narrative “misses the stories about countries like Tuvalu that are really international leaders in climate policy”.
Similarly, images of power-plant smoke stacks, often used in online climate media articles, almost always omit the people that live alongside them, “breathing their pollution”, she said.
During the panel discussion that followed, panellist Dr James Painter – a research associate at the Reuters Institute for the Study of Journalism and senior teaching associate at the University of Oxford’s Environmental Change Institute – highlighted his work on heatwave imagery in the media.
Painter said that “the UK was egregious for its ‘fun in the sun’ imagery” during dangerous heatwaves.
He highlighted a series of images in the Daily Mail in July 2019 depicting people enjoying themselves on beaches or in fountains during an intense heatwave – even as the text of the piece spoke to the negative health impacts of the heatwave.
In contrast, he said his analysis of Indian media revealed “not one single image of ‘fun in the sun’”.
Meanwhile, climate journalist Katherine Dunn asked: “Are we still using and abusing the polar bear?”. O’Neill suggested that polar bear images “are distant in time and space to many people”, but can still be “super engaging” to others – for example, younger audiences.
Panellist Dr Rebecca Swift – senior vice president of creative at Getty images – identified AI-generated images as “the biggest threat that we, in this space, are all having to fight against now”. She expressed concern that we may need to “prove” that images are “actually real”.
However, she argued that AI will not “win” because, “in the end, authentic images, real stories and real people are what we react to”.
When asked if we expect too much from images, O’Neill argued “we can never pin down a social change to one image, but what we can say is that images both shape and reflect the societies that we live in”. She added:
“I don’t think we can ask photos to do the work that we need to do as a society, but they certainly both shape and show us where the future may lie.”
Watch, read, listen
UNSTOPPABLE WILDFIRES: “Funding cuts, conspiracy theories and ‘powder keg’ pine plantations” are making Patagonia’s wildfires “almost impossible to stop”, said the Guardian.
AUDIO SURVEY: Sverige Radio has published “the world’s, probably, longest audio survey” – a six-hour podcast featuring more than 200 people sharing their questions around climate change.

DeBriefed 30 January 2026: Fire and ice; US formally exits Paris; Climate image faux pas
Electric heat pumps are set to play a key role in the UK’s climate strategy, as well as cutting the nation’s reliance on imported fossil fuels.
Heat pumps took centre-stage in the UK government’s recent “warm homes plan”, which said that they could also help cut household energy bills by “hundreds of pounds” a year.
Similarly, innovation agency Nesta estimates that typical households could cut their annual energy bills nearly £300 a year, by switching from a gas boiler to a heat pump.
Yet there has been widespread media coverage in the Times, Sunday Times, Daily Express, Daily Telegraph and elsewhere of a report claiming that heat pumps are “more expensive” to run.
The report is from the Green Britain Foundation set up by Dale Vince, owner of energy firm Ecotricity, who campaigns against heat pumps and invests in “green gas” as an alternative.
One expert tells Carbon Brief that Vince’s report is based on “flimsy data”, while another says that it “combines a series of worst-case assumptions to present an unduly pessimistic picture”.
This factcheck explains how heat pumps can cut bills, what the latest data shows about potential savings and how this information was left out of the report from Vince’s foundation.
How heat pumps can cut bills
Heat pumps use electricity to move heat – most commonly from outside air – to the inside of a building, in a process that is similar to the way that a fridge keeps its contents cold.
This means that they are highly efficient, adding three or four units of heat to the house for each unit of electricity used. In contrast, a gas boiler will always supply less than one unit of heat from each unit of gas that it burns, because some of the energy is lost during combustion.
This means that heat pumps can keep buildings warm while using three, four or even five times less energy than a gas boiler. This cuts fossil-fuel imports, reducing demand for gas by at least two-fifths, even in the unlikely scenario that all of the electricity they need is gas-fired.
Since UK electricity supplies are now the cleanest they have ever been, heat pumps also cut the carbon emissions associated with staying warm by around 85%, relative to a gas boiler.
Heat pumps are, therefore, the “central” technology for cutting carbon emissions from buildings.
While heat pumps cost more to install than gas boilers, the UK government’s recent “warm homes plan” says that they can help cut energy bills by “hundreds of pounds” per year.
Similarly, Nesta published analysis showing that a typical home could cut its annual energy bill by £280, if it replaces a gas boiler with a heat pump, as shown in the figure below.
Nesta and the government plan say that significantly larger savings are possible if heat pumps are combined with other clean-energy technologies, such as solar and batteries.
Both the government and Nesta’s estimates of bill savings from switching to a heat pump rely on relatively conservative assumptions.
Specifically, the government assumes that a heat pump will deliver 2.8 units of heat for each unit of electricity, on average. This is known as the “seasonal coefficient of performance” (SCoP).
This figure is taken from the government-backed “electrification of heat” trial, which ran during 2020-2022 and showed that heat pumps are suitable for all building types in the UK.
(The Green Britain Foundation report and Vince’s quotes in related coverage repeat a number of heat pump myths, such as the idea that they do not perform well in older properties and require high levels of insulation.)
Nesta assumes a slightly higher SCoP of 3.0, says Madeleine Gabriel, the organisation’s director of sustainable future. (See below for more on what the latest data says about SCoP in recent installations.)
Both the government and Nesta assume that a home with a heat pump would disconnect from the gas grid, meaning that it would no longer need to pay the daily “standing charge” for gas. This currently amounts to a saving of around £130 per year.
Finally, they both consider the impact of a home with a heat pump using a “smart tariff”, where the price of electricity varies according to the time of day.
Such tariffs are now widely available from a variety of energy suppliers and many have been designed specifically for homes that have a heat pump.
Such tariffs significantly reduce the average price for a unit of electricity. Government survey data suggests that around half of heat-pump owners already use such tariffs.
This is important because on the standard rates under the price cap set by energy regulator Ofgem, each unit of electricity costs more than four times as much as a unit of gas.
The ratio between electricity and gas prices is a key determinant of the size and potential for running-cost savings with a heat pump. Countries with a lower electricity-to-gas price ratio consistently see much higher rates of heat-pump adoption.
(Decisions taken by the UK government in its 2025 budget mean that the electricity-to-gas ratio will fall from April, but current forecasts suggest it will remain above four-to-one.)
In contrast, Vince’s report assumes that gas boilers are 90% efficient, whereas data from real homes suggests 85% is more typical. It also assumes that homes with heat pumps remain on the gas grid, paying the standing charge, as well as using only a standard electricity tariff.
Prof Jan Rosenow, energy programme leader at the University of Oxford’s Environmental Change Institute, tells Carbon Brief that Vince’s report uses “worst-case assumptions”. He says:
“This report cherry-picks assumptions to reach a predetermined conclusion. Most notably, it assumes a gas boiler efficiency of 90%, which is significantly higher than real-world performance…Taken together, the analysis combines a series of worst-case assumptions to present an unduly pessimistic picture.”
Similarly, Gabriel tells Carbon Brief that Vince’s report is based on “flimsy data”. She explains:
“Dale Vince has drawn some very strong conclusions about heat pumps from quite flimsy data. Like Dale, we’d also like to see electricity prices come down relative to gas, but we estimate that, from April, even a moderately efficient heat pump on a standard tariff will be cheaper to run than a gas boiler. Paired with a time-of-use tariff, a heat pump could save £280 versus a boiler and adding solar panels and a battery could triple those savings.”
What the latest data shows about bill savings
The efficiency of heat-pump installations is another key factor in the potential bill savings they can deliver and, here, both the government and Vince’s report take a conservative approach.
They rely on the “electrification of heat” trial data to use an efficiency (SCoP) of 2.8 for heat pumps. However, Rosenow says that recent evidence shows that “substantially higher efficiencies are routinely available”, as shown in the figure below.
Detailed, real-time data on hundreds of heat pump systems around the UK is available via the website Heat Pump Monitor, where the average efficiency – a SCoP of 3.9 – is much higher.
Homes with such efficient heat-pump installations would see even larger bill savings than suggested by the government and Nesta estimates.
Academic research suggests that there are simple and easy-to-implement reasons why these systems achieve much higher efficiency levels than in the electrification of heat trial.
Specifically, it shows that many of the systems in the trial have poor software settings, which means they do not operate as efficiently as their heat pump hardware is capable of doing.
The research suggests that heat pump installations in the UK have been getting more and more efficient over time, as engineers become increasingly familiar with the technology.
It indicates that recently installed heat pumps are 64% more efficient than those in early trials.
Notably, the Green Britain Foundation report only refers to the trial data from the electrification of heat study carried out in 2020-22 and the even earlier “renewable heat premium package” (RHPP). This makes a huge difference to the estimated running costs of a heat pump.
Carbon Brief analysis suggests that a typical household could cut its annual energy bills by nearly £200 with a heat pump – even on a standard electricity tariff – if the system has a SCoP of 3.9.
The savings would be even larger on a smart heat-pump tariff.
In contrast, based on the oldest efficiency figures mentioned in the Green Britain Foundation report, a heat pump could increase annual household bills by as much as £200 on a standard tariff.
To support its conclusions, the report also includes the results of a survey of 1,001 heat pump owners, which, among other things, is at odds with government survey data. The report says “66% of respondents report that their homes are more expensive to heat than the previous system”.
There are several reasons to treat these findings with caution. The survey was carried out in July 2025 and some 45% of the heat pumps involved were installed between 2021-23.
This is a period during which energy prices surged as a result of Russia’s invasion of Ukraine and the resulting global energy crisis. Energy bills remain elevated as a result of high gas prices.
The wording of the survey question asks if homes are “more or less expensive to heat than with your previous system” – but makes no mention of these price rises.
The question does not ask homeowners if their bills are higher today, with a heat pump, than they would have been with the household’s previous heating system.
If respondents interpreted the question as asking whether their bills have gone up or down since their heat pump was installed, then their answers will be confounded by the rise in prices overall.
There are a number of other seemingly contradictory aspects of the survey that raise questions about its findings and the strong conclusions in the media coverage of the report.
For example, while only 15% of respondents say it is cheaper to heat their home with a heat pump, 49% say that one of the top three advantages of the system is saving money on energy bills.
In addition, 57% of respondents say they still have a boiler, even though 67% say they received government subsidies for their heat-pump installation. It is a requirement of the government’s boiler upgrade scheme (BUS) grants that homeowners completely remove their boiler.
The government’s own survey of BUS recipients finds that only 13% of respondents say their bills have gone up, whereas 37% say their bills have gone down, another 13% say they have stayed the same and 8% thought that it was too early to say.
