The leader of the opposition Conservative party, Kemi Badenoch, has shattered the political consensus on climate change in a speech attacking the UK’s net-zero by 2050 target.
In a speech launching a “policy renewal programme” to shape the Conservatives’ approach to key issues, Badenoch disowned the target passed into law by her own party in 2019.
She offered no alternative to the 2050 net-zero target and failed to cite any evidence in support of her assertion that meeting it would be “impossible” without “bankrupting” the country.
As a government minister in 2022, Badenoch had touted the “opportunity” for “growth and revitalised communities” as a result of the “clean energy revolution”.
However, she then ran her leadership campaign as a “net-zero sceptic” from the home of Neil Record, the chair of the UK’s main climate-sceptic lobby group Net Zero Watch.
Her speech received widespread media coverage, including frontpage stories for the Daily Mail, the Times and the Daily Telegraph, as well as editorials from the Daily Telegraph and the Sun.
In this factcheck, Carbon Brief looks at the evidence on the UK’s net-zero target and how it contradicts the claims made by Badenoch in her speech.
- Net-zero is ‘the only way’ to stop global warming
- Net-zero by 2050 in the UK is ‘feasible’ and ‘affordable’
- The UK has a ‘delivery plan’ to meet its climate goals
- Reaching net-zero will be ‘73% cheaper than thought’
- Unchecked warming would be ‘catastrophic’ for public finances
- High gas prices are making energy bills expensive
- Net-zero will ‘make energy cheaper, not more costly’
- Net-zero makes energy ‘more secure’
- Two-thirds of UK public backs net-zero by 2050
- More than 80% of world’s population covered by net-zero targets
Net-zero is ‘the only way’ to stop global warming
In her speech, Badenoch claimed that she was committed to “safeguard[ing] the delicate balance of nature for future generations” and that she was offering “three truths” about net-zero.
Yet she also falsely claimed that “no one knows” why the UK has a net-zero by 2050 target.
The Intergovernmental Panel on Climate Change (IPCC) has detailed the extensive evidence that it will be impossible to stop global warming without reaching net-zero.
In its latest assessment report, the IPCC explained:
“Without net-zero CO2 emissions, and a decrease in the net non-CO2 forcing (or sufficient net negative CO2 emissions to offset any further warming from net non-CO2 forcing), the climate system will continue to warm.”
Speaking at the report launch, IPCC Working Group I co-chair Dr Valérie Masson-Delmotte said reaching net-zero emissions was the “only way to limit global warming”. She said:
“This report reaffirms that there is a near-linear relationship between the cumulative amount of emissions of CO2 in the atmosphere from human activities and the extent of observed and future warming. This is physics. This means that the only way to limit global warming is to reach net-zero CO2 emissions at the global scale. Every additional tonne of CO2 emissions adds to global warming.”
This is why the 2015 Paris Agreement, signed by almost every country in the world, targets a “balance” between greenhouse gas sources and the “sinks” that remove them from the atmosphere .
The IPCC also explained that limiting warming by the end of the century to less than 1.5C above pre-industrial levels would require emissions to reach net-zero globally by the “early 2050s”.
In 2019, the UK’s advisory Climate Change Committee (CCC) considered the breadth of scientific evidence, the economics of the transition, as well as societal and technological trends when it offered detailed advice – covering 277 pages – on setting a net-zero by 2050 target.
This advice formed the basis for the then-Conservative government’s decision to put the net-zero target into law, by amending the UK’s 2050 target under the 2008 Climate Change Act from an 80% reduction in emissions to a 100% goal.
With the academies of other G7 nations, the UK’s Royal Society set out the “need” for countries to “carefully design, plan and accelerate action to reach net-zero by 2050 or earlier”. It said:
“Science tells us we must act now and continue to act into the future to deliver net-zero emissions if we are to avoid unacceptable warming.”
When she signed the net-zero target into law in 2019, former Conservative prime minister Theresa May said that the goal was “a conservative mission to end our contribution to climate change and build a more prosperous and resilient economy”.
Net-zero by 2050 in the UK is ‘feasible’ and ‘affordable’
Despite the clear evidence of the need to reach net-zero emissions to stop global warming, Badenoch said in her speech that reaching the target by 2050 was “impossible”.
She did not offer any evidence to support this supposedly “unvarnished truth”.
Announcing the adoption of the target in 2019, Conservative then-secretary of state Greg Clark said that it was “necessary and feasible”, pointing to the CCC’s advice as evidence.
Indeed, the 2019 advice set out in detail how it would be “feasible” to cut UK emissions to net-zero by 2050. In its latest advice to the government, the CCC set out a “balanced pathway” to net-zero by 2050 that showed the target was “feasible and deliverable”.
Similarly, in 2024 the National Energy System Operator (NESO) published three “credible” and “affordable” pathways to net-zero by 2050, as part of its annual “future energy scenarios”. It said:
“Our net-zero pathways identify three credible, strategic routes to reach net-zero…Decisive action is needed within the next two years to deliver the fundamental change required for a fair, affordable, sustainable and secure net-zero energy system by 2050.”
A peer-reviewed research paper in 2022 identified and compared seven pathways to net-zero by 2050, published by four different organisations.
Directly contradicting Badenoch’s speech, the study concluded that “the breadth of pathways analysed in this paper has shown that there are several possible routes to net-zero”.
Moreover, the Conservative government in 2021 published its own strategy for reaching net-zero by 2050, including an entire section titled “why net-zero”.
In a foreword to the 2021 strategy, then-Conservative prime minister Boris Johson wrote that “reaching net-zero is entirely possible”.
An updated 2023 strategy published under Conservative prime minister Rishi Sunak – when Badenoch was secretary of state for business and trade – says that “the transition to net-zero will provide the economic opportunity of the 21st century”.
At a global level, the International Energy Agency (IEA) has published a pathway “for the global energy sector to achieve net-zero CO2 [carbon dioxide] emissions by 2050, with advanced economies reaching net-zero emissions in advance of others”.
In addition to meeting global climate goals, the IEA’s pathway also meets “key energy-related sustainable development goals (SDGs), in particular universal energy access by 2030 and major improvements in air quality”.
Numerous other global pathways showing how to reach net-zero emissions by or around 2050 have been published, as summarised by the IPCC’s latest assessment report.
The UK has a ‘delivery plan’ to meet its climate goals
Another of the ideas promoted in Badenoch’s speech is that there has “never, ever been a detailed plan” to reach net-zero or other UK climate goals.
This is flatly contradicted by the extensive legislative and policy framework set up around UK climate targets under the 2008 Climate Change Act.
This legislation requires the government to seek and take into account the CCC’s advice on how to reach net-zero. It also requires the government, under sections 13 and 14 of the act, to prepare and publish “proposals and policies” that “will enable” the UK’s legally binding targets to be met.
The UK’s 2021 strategy was subject to legal challenge and was subsequently ruled unlawful for failing to publicly spell out the ways it would cut UK emissions, policy by policy.
However, these numbers – quantifying the impact of each policy to cut emissions – had always been available behind the scenes. They were later published as part of a revised, highly detailed “delivery plan” for meeting the UK’s goals.
Indeed, it was published in 2023 alongside a veritable “avalanche” of plans and policies, amounting to nearly 3,000 pages of documents on how the UK was going about cutting its emissions.
While this revised strategy was later ruled unlawful once again, it is hard to argue that there has “never, ever been a detailed plan”.
The Labour government has until May 2025 to submit a revised delivery plan to the high court.
Reaching net-zero will be ‘73% cheaper than thought’
In addition to claiming that there is no plan for reaching net-zero, Badenoch claimed that this fictional absence is because it “would reveal just how catastrophic the actual costs will be for families, for businesses and for our economy”.
Badenoch also claimed falsely that reaching net-zero would be a “multi-trillion” project and that it could only be reached by “bankrupting us”. She said:
“Anyone who has done any serious analysis knows it cannot be achieved without a significant drop in our living standards or worse, by bankrupting us.”
Her speech follows a wave of “scary-sounding numbers” being thrown around the UK debate about net-zero over the past 18 months.
Invariably, these arguments – and the numbers behind them – focus on the costs of reaching net-zero without mentioning the costs of business-as-usual; look at the cost of cutting emissions, but not the benefits; or ignore the costs of failing to tackle climate change.
On the contrary, the only “serious analysis” – as Badenoch quipped – on the economic impact of the UK’s net-zero target, has found that meeting the goal will require significant, but affordable investments, which will deliver long-term savings in terms of lower bills for importing fossil fuels.
Badenoch herself, while a minister in 2022, touted the “opportunity, growth and revitalised communities” offered by “the clean energy revolution”, which she said was the “future-proofing force that will help us create a better tomorrow”.
Her comments echoed the independent review commissioned by the government she was part of at the time, which concluded that net-zero was the “growth opportunity of the 21st century”.
It added that while significant investments would be needed – primarily from the private sector – the “benefits of investing in net-zero today outweigh the costs”.
Similarly, in its latest advice to the government, the CCC concluded that the UK would need to make additional investments totalling less than £700bn over the 25 years to 2050.
This was significantly lower than the £1.3tn estimate published just five years earlier and several times lower than the “multi-trillion” cost claimed by Badenoch.
Those investments would deliver almost equally large operational savings of £600bn, due to more efficient electrified heat, transport and industry needing less fossil fuel imports.
In total, the CCC therefore estimated that the net cost of reaching net-zero would amount to just over £100bn over 25 years, equivalent to £4bn per year or 0.2% of GDP.
This £100bn net cost is 73% lower than the CCC’s estimate from five years earlier, Carbon Brief analysis found.
Moreover, the CCC said that the large majority of the investment required – some 65-90% – would come from the private sector, rather than from government coffers.
In a statement responding to Badenoch’s speech, Dhara Vyas, the head of Energy UK agreed on the need for “honest conversations”, but added that delaying investments “increases the eventual cost” and – as per Carbon Brief analysis – had already “added billions to bills”. She said:
“Of course we need honest conversations about how we fund the costs in a way that is fair to households and businesses – and this also needs to include a consideration of the potential price of inaction. Delaying upfront investment increases the eventual cost and rowing back on green measures added billions to bills during the gas crisis.”
Unchecked warming would be ‘catastrophic’ for public finances
Badenoch’s speech did not mention the costs of unchecked warming. Instead, she described the UK’s approach to climate policy as “fantasy politics…Promising the Earth. And costing it too.”
In contrast, the Office for Budget Responsibility (OBR) concluded in 2021: “Unmitigated climate change would ultimately have catastrophic economic and fiscal consequences.”
This was, in part, due to the impact of increasingly severe extreme weather events, which the OBR subsequently said might cost the UK nearly 8% of GDP by 2050.
The conclusion was also based on the fact that shifting to clean energy would reduce the UK’s exposure to volatile fossil fuel prices set by international markets. It said:
“There is a risk that the UK economy remains relatively highly dependent on imported gas…Continued dependence on gas could be as expensive fiscally as completing the transition to net-zero”.
Furthermore, the OBR found that delaying action “could double the overall cost” to the UK of cutting emissions to net-zero.
In its own 2021 review of the net-zero target, the Treasury under Rishi Sunak said that unchecked climate change would be a “significant fiscal risk” and that while the transition to net-zero would have “material fiscal consequences”, those consequences could be “managed”. It added:
“Furthermore, the increased investment required to transition to net-zero creates opportunities for growth and employment.”
This is illustrated by a February 2025 report from the Confederation for British Industry (CBI), which concluded that net-zero was making a “growing contribution” to the UK economy. It said:
“Think going green is just a nice idea? Think again. The net-zero economy has become a powerhouse of job creation and economic expansion with 10.1% growth in the total economic value supported by the net-zero economy since 2023.”
The report found that the net-zero economy was growing three times faster than other sectors. Responding to Badenoch’s speech, CBI head Rain Newton-Smith said in a statement:
“Now is not the time to step back from the opportunities of the green economy. Cross-party support for net-zero has underpinned international investors’ confidence to choose the UK for investment in the energy transition.”
High gas prices are making energy bills expensive
Part of Badenoch’s argument against the net-zero target is her claim that the UK’s current climate policies are “driving up the cost of energy”. In her speech, she said:
“The cost of electricity – far too high – much higher than nearby and comparative countries with the real possibility of it going even higher with environmental levies.”
The UK does face very high electricity prices relative to many other countries. However, contrary to Badenoch’s speech, the UK’s extreme exposure to gas prices is the main reason for this.
(As Energy UK’s Vyas notes in her statement, “it’s the volatile cost of fossil fuels and our dependence on them that have driven up energy bills for customers”.)
Indeed, the UK’s wholesale electricity prices are almost entirely dictated by the price of gas, which remains more than three times more expensive than before the global energy crisis.
This near-perfect correlation between gas and power prices is shown in the figure below. (Note that Northern Ireland is part of the separate all-Ireland electricity market.)
While the UK’s electricity was the “cleanest ever” in 2024, with a record-low share coming from fossil fuels, gas continues to set the price of electricity during the vast majority of hours.
This is a result of the “marginal pricing” system used in most countries around the world. Specifically, gas sets the wholesale price of electricity in the UK during 98% of hours, whereas the EU average is less than 40%, as shown in the figure below.
The government’s target of clean power by 2030 is expected to significantly reduce the amount of time when gas sets the price of electricity.
In one of the scenarios set out in NESO advice last autumn, gas would set the price in just 15% of hours by 2030, insulating consumers from “volatile international gas prices”.
While the UK’s high exposure to gas prices is the main reason for high electricity bills, the government is also under pressure to cut other costs, including the cost of building and operating the electricity system, as well as funding historical support for renewable projects.
A long-running government review of the way the electricity market operates is due to reach a conclusion by summer 2025. This could result in changes designed to reduce the influence of gas on electricity prices and to make the system more efficient, among other things.
In a March 2025 report, Energy UK set out a range of shorter-term options to cut the price of electricity, most prominently removing policy costs from electricity bills and paying them via gas bills or from general taxation. This shifting of costs is known as “rebalancing”.
The CCC’s recent advice to government also called for policy costs – which make up around 25% of household electricity prices – to be rebalanced onto gas bills or taxation.
Net-zero will ‘make energy cheaper, not more costly’
In the longer term – and contrary to what Badenoch implies in her speech – the transition to clean energy is widely expected to cut household energy costs.
Looking specifically at the UK, the CCC said in February 2025 that shifting towards net-zero would help cut household energy bills and motoring costs by £1,400 per year by 2050.
It said that household energy bills for heat and power would fall by £700 in 2050, compared with current levels, and that the cost of fuelling cars would fall by a similar amount.
In a pre-launch press briefing, CCC chief executive Emma Pinchbeck addressed MPs arguing against the transition to net-zero, telling journalists that their opposition amounted to being hostile to lower bills for their constituents. She said:
“If you are an elected representative who is hostile to renewables, heat pumps, electric vehicles, what our numbers say is you are also hostile to your constituents saving £700 on their energy bill and [another] £700 on their fuel bill through making those changes.”
At a global level, the IEA concluded that reaching net-zero by 2050 would “make energy cheaper, not more costly”.
Strikingly, the IEA concluded that accelerating climate action to reach net-zero emissions by 2050 would make the global energy system “more affordable and fairer”.
According to the agency, this is because higher investment costs would be more than offset by lower fuel bills, greater efficiency and reduced fossil fuel rents. It concluded:
“Energy transitions could lead to major reductions in household energy bills and accelerate progress towards universal energy access. But managing upfront costs for poorer and rural households – as well as ongoing costs – remains a key public policy challenge.”
Net-zero makes energy ‘more secure’
Another key part of Badenoch’s speech was her argument that net-zero “makes us dangerously dependent on countries who don’t share our values and it is risking our energy security”.
She did not find space in her speech to mention the UK’s current exposure to expensive fossil fuel imports, many of which come from what she refers to as “countries who don’t share our values”.
Indeed, the UK’s exposure to international gas prices, which surged following Russia’s invasion of Ukraine in 2022, left the country the “worst hit” in western Europe by the subsequent global energy crisis, according to Guardian coverage of a report from the International Monetary Fund.
The government’s target to shift to clean power by 2030 would leave the country “much less reliant on energy imports for power and far less exposed to fluctuations in international gas prices”, according to NESO advice published last November.
The wider shift away from fossil fuels, towards electrified heat and transport, would mean the UK could cut its oil imports tenfold from current levels by 2050 and its gas imports by two-thirds, according to the CCC’s recently published pathway to net-zero.
While Badenoch said that she, too, supported the shift to renewables “when they make energy cheaper and more secure”, she also claimed that they would leave the UK “heavily dependent on China”. The country currently manufactures most of the world’s solar panels and large proportions of the batteries and other clean technologies needed to decarbonise.
The shift away from fossil fuels towards clean energy will indeed reshape the geopolitics of global energy supplies. However, Badenoch omits the fundamentally different nature of buying an electric vehicle, which can be fuelled with domestically produced electricity, compared with a petrol car, for which imported fuel must be bought, burned and then bought again and again.
In its 2023 energy security strategy, the then-Conservative government said that the shift to clean energy was the “most effective route to ensuring both climate and energy security”, which would help “avoid risks associated with dependency on fossil fuels”.
Two-thirds of UK public backs net-zero by 2050
In its coverage of Badenoch’s speech, Bloomberg reports that her positioning on net-zero is an attempt to win back votes lost to the hard-right, climate-sceptic Reform UK party.
Ever since the Uxbridge byelection in July 2023, the Conservatives had been tacking away from their historical support for climate policies in general and the net-zero target in particular.
This shift saw then-prime minister Rishi Sunak make a September 2023 speech in which he abandoned or delayed key parts of the then-government’s climate strategy.
Using similar language to Badenoch’s speech, Sunak said at the time that he was adopting an “honest” approach to net-zero and that he was going to remove “unacceptable costs” from “hard-working British people”. Several of his changes would have cost consumers billions.
Many political observers noted at the time that this approach carried electoral risks for the Conservatives. Even some within the party argued that the “right lessons” needed to be drawn from the Uxbridge result. Yet Badenoch has doubled down, going even further than Sunak.
This is despite the fact that anti net-zero rhetoric from the Conservatives was reportedly at least partly to blame for their loss in last year’s general election.
Indeed, some 65%% of the UK public backs the net-zero by 2050 target, according to polling by Climate Barometer, compared with 22% who oppose it.
Moreover, 55% of Conservative voters back the target, as well as 90% of MPs.
YouGov polling released on the day of Badenoch’s speech found that 61% of people in Great Britain support net-zero and just 24% oppose it.
Among those who voted Conservative in the last election 52% support the goal and 38% oppose it, according to the YouGov results.
More than 80% of world’s population covered by net-zero targets
One final point raised by Badenoch’s speech is that even if the UK were to reach net-zero, global emissions would not be guaranteed to reach net-zero overall.
She went on to claim that “other countries are not following us”. Contrary to this claim, some 142 countries – representing more than 80% of the world’s population – are covered by net-zero targets.

Factcheck: Why Conservative leader Kemi Badenoch is wrong about UK’s net-zero goal
Last month, COP31 president-designate Murat Kurum launched a target for 35% of the world’s final energy to come from electricity by 2035.
In an interview with Carbon Brief, Kurum says that the target was not a political choice, but instead reflects the latest evidence on “what is needed to keep 1.5C within reach”.
The ongoing Hormuz crisis means there is an “urgent” need for renewables and electrification, which are the “surest and cleanest way to protect citizens” from high energy prices.
Kurum says that the Brazilian and Ethiopian presidencies of COP30 and COP32, as well as the EU, UK and Canada, have welcomed the target.
He adds that “all have confirmed it will be central to discussions at COP31”.
In the interview, Kurum – who is also Turkey’s minister of environment, urbanisation and climate change – tells Carbon Brief where the target came from and what he expects to happen next.
Carbon Brief: You recently launched a target for 35% of the world’s final energy to come from electricity by 2035. Where did this idea come from?
Murat Kurum: The “35 by 35” target is grounded in technical data and based on the IEA [International Energy Agency] and IRENA [International Renewable Energy Agency] analysis of what is needed to keep [the 1.5C Paris Agreement target] within reach. The level was not chosen politically. Rather, it reflects what the science and the energy modelling tell us is required.
CB: Why do you think an electrification target is important right now?
MK: The case for the target is urgent right now. The latest war in the Gulf has made energy diversification – and, in particular, renewable energy transition and electrification – a top global priority, because it is the surest and cleanest way to protect citizens around the world from high and volatile energy prices.
At a time of real fragmentation in international relations, a single, shared target is needed to focus global efforts by aligning governments, businesses and investors behind a common benchmark and to send a clear market signal.
CB: Which countries are supporting this target so far?
MK: The reaction so far has been extremely positive and, while we presented our target at the UN June climate meetings in Bonn, our earlier conversations with parties at both the Petersberg and Copenhagen climate dialogues paved the way for this launch.
For example, the EU, UK, and Canada have welcomed the target, as have the Brazilian COP30 and Ethiopian COP32 presidencies. All have confirmed it will be central to discussions at COP31.
This support has been reflected in the business community as well, with polling by the We Mean Business Coalition showing that 90% of businesses expect to have largely electrified their operations by 2035 and that 88% expect electrification will make their business more competitive.
CB: How do you hope and expect to see this taken forward at the COP? Could it be in the formal COP outcomes, or part of the second global stocktake?
MK: We are now taking electrification forward as an “action agenda” initiative to bring actors together and drive progress. The action agenda and the [formal COP] negotiations are separate, but complementary, with different processes and thresholds, and it is too early to say what all countries might be able to agree in the negotiations. That is for parties to determine as the year progresses.
We are focused and determined to use COP31 as a moment to spark a global conversation about electrification.
CB: What are the key priorities for reaching the target?
MK: The critical sectors for reaching the target are buildings, transport and industry, which together account for around 45% of global emissions. Financial support for the developing world and investment in grids and infrastructure is also crucial.
The target also builds on COP28’s target to triple renewable energy capacity and seeks to take advantage of the tumbling cost of renewable power and other technologies critical to the energy transition. This is a journey that Turkey itself is taking ambitious steps on, including our plan to reach 120GW [gigawatts] of renewable capacity by 2035.

DeBriefed 10 July 2026: Deadly Europe heat | EU electrification leak | COP31 president interview
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
‘Catastrophic’ climate impacts
RECORD HEAT: Western Europe experienced its hottest June on record – some 3C above average – according to analysis covered by the Guardian. It said the finding came “as the UK enters its third heatwave of the year and wildfires ravage France and Spain”. Le Monde said 10,000 people had been evacuated due to wildfires in southern France.
‘EXCESS DEATHS’: The June heatwave killed more than 2,700 people in France, according to a guest post analysis for Carbon Brief. Similar analysis for Germany said there had been more than 5,000 “excess deaths”, reported Bloomberg. Meanwhile, an ongoing heatwave in the US has killed at least 30 people, said USA Today.
STORM TEST: Floods have killed 39 people in Guangxi province in southern China, said state-run newspaper China Daily. Scientists warned that climate change and the weather phenomenon El Niño are exposing China to “catastrophic storms” that will test its resilience in 2026, reported Reuters. The nation’s latest official climate report found that “extreme weather and climate events…have become more frequent and severe”, said China National Radio.
Around the world
- EU ELECTRIFICATION: The European Commission is set to unveil a 2040 target for EU electrification on 17 July, reported Bloomberg. Citing a leaked draft, it said the plan would aim to cut oil use in half and gas use by two-thirds.
- PEAKING PLAN: China has published an “action plan” for peaking emissions during the 15th five-year plan period to 2030, reported Xinhua. It lists targets including “new energy vehicles” making up 30% of cars on the road by 2030, said Reuters.
- CLIMATE ‘FLAT EARTHER’: The Trump administration has appointed Matthew Wielicki, described by Politico as a “climate critic”, to lead the office in charge of the US national climate assessment. Common Dreams quoted a scientist describing the move as “like putting a flat-earther in charge of NASA”.
- UGANDAN SUIT: A group of farmers from Uganda have launched a legal suit in London against the East African oil pipeline, according to Climate Home News.

Captured
Carbon Brief explained – via eight facts – why air conditioning rates in some parts of Europe are relatively low, as the technology emerges as a new front in the global “culture war” over climate action. Analysis for the article illustrated that, in many parts of the world’s fastest-warming continent, air conditioning simply was not needed in the past.
Spotlight
COP31 president speaks to Carbon Brief on electrification
This week, Carbon Brief interviews Murat Kurum, president-designate of the COP31 UN climate talks in November and Turkey’s minister of environment, urbanisation and climate change, on his target to boost global electrification.

DeBriefed 10 July 2026: Deadly Europe heat | EU electrification leak | COP31 president interview
As successive heatwaves hit Europe, air-conditioning (AC) has emerged as a new front in the international “culture war” over climate action.
France, Germany and the UK have experienced record-breaking heat and thousands of heat-related deaths this summer, with June temperatures in many regions passing 40C.
This has drawn attention to the relatively low rates of AC use in these countries – and in Europe as a whole – especially when compared to its widespread adoption in the US.
Legacy newspapers, bloggers and even Elon Musk have all weighed in on “European hostility” to AC, criticising Europe’s “cultural conservatism” and “overbearing governments”.
Right-wing politicians, including National Rally in France and the UK Conservatives, have styled themselves as champions of AC, while opposing efforts to tackle climate change.
Missing from most of these interventions is the fact that human-caused climate change has made once-rare heat far more common, in what is the world’s fastest warming continent.
Carbon Brief analysis for this article shows that, until the 2020s, it was rare for many European cities to see days above 30C, making AC an unnecessary expense.
Here, Carbon Brief explains – via eight facts – why AC rates in some parts of Europe are relatively low, as well as clarifies and contextualises some of the misleading claims circulating about the technology.
- Much of Europe has not needed AC in the past
- AC is already widely used in hotter parts of Europe
- Some European nations have ‘resisted’ AC – but its popularity is growing
- AC emissions are growing, but its climate impact could be limited
- Heat from AC can contribute to directly warming cities
- More AC could help to reduce heat deaths in Europe
- ‘Net-zero rules’ are not blocking AC installation in the UK
- AC is not the only answer to overheating cities
Much of Europe has not needed AC in the past
AC installation rates in northern parts of Europe are very low. The best available estimates suggest that 6% of households in Germany and just 4% in England use AC.
However, these rates are largely explained by the historical climates in these nations.
Unlike the US, much of the housing stock and infrastructure in Europe was built at a time when AC did not exist and was not necessary.
Moreover, nations such as France, Germany and the UK have only started to regularly experience extreme heat in recent decades.
The chart below shows the average number of days per year, in each decade since the 1950s, when maximum temperatures have exceeded 30C in major European cities. Capitals such as London and Paris have seen a significant jump since around 2000.
Prof Jan Rosenow, an energy and climate researcher at the University of Oxford, tells Carbon Brief:
“For most of the 20th century, northern Europe simply didn’t need cooling. Homes in Britain and Germany were built to keep heat in, not out, because winters were cold and summers rarely hot.”
Much of the commentary about the relatively low rates of European AC use focuses on cultural or “ideological” factors. (See: Some European nations have ‘resisted’ AC – but its popularity is growing.)
However, Rosenow says people’s views on AC in these countries likely stem from their historically colder climates. He adds:
“Attitudes formed around those facts, not the other way round…There is a cultural element, but it is the product of climate, not of some green ideological project.”
In the past, many in Europe relied on traditional methods to keep buildings cool. Richard Black, head of communications at Climate Analytics, made this point in a post on LinkedIn:
“Once, residents of cities such as Paris could cope with summer heatwaves by opening shutters and windows during the night, and closing them again in the morning to trap the cool air inside…We’ve reached a limit to this sort of adaptation.”
Now, with Europe around 2.5C warmer than pre-industrial levels, climate change is routinely driving record-breaking heatwaves, even in the north of the continent.
This is forcing a reappraisal of societies that were “built for a climate that no longer exists”, as the UK’s Climate Change Committee (CCC) put it in a recent report.
Experts broadly agree that much of Europe will indeed need more AC, particularly in spaces housing the most vulnerable populations, such as care homes, schools and hospitals.
At the same time, they also emphasise broader, “passive” efforts to make cities and homes cooler alongside increased AC use. (See: AC is not the only answer to overheating cities.)
AC is already widely used in hotter parts of Europe
During periods of extreme heat, articles criticising “European hostility” towards the technology frequently note that “only about 20%” of households in Europe have AC.
Often, this is contrasted with the US, where more than 90% of households have AC installed. (In fact, the US is something of a global outlier, matched only by Japan.)
However, the continent-wide figure for Europe obscures the reality. In southern Europe – where temperatures are and have always been higher – AC is relatively common.
The map below, based on official EU data, shows that southern European nations use far more household energy for “space cooling” than those in the north.
Government figures show that nearly 60% of Italian households have AC. Household-level data in many countries is patchy, but various analyses have placed that figure at 70-80% in Greece and 41% in Spain – with higher penetration in the hotter, southern part of the country.
The same pattern can be seen within France. International coverage has stressed the country’s “cultural resistance to AC”, citing a nationwide figure from 2020 that suggests “only” 25% of French households have AC.
However, polling data from customers of the Hello Watt energy app suggests that there is a distinct north-south divide in French uptake. At least 60% of households in Mediterranean regions of France are equipped with AC, according to these figures.
This can be seen in the map below, with households across northern regions, including Paris, reporting far lower AC installation rates, often below 5%.
Finally, when making such comparisons to Europe, it is worth noting that high rates of AC use reported for the entire US also obscure significant differences between – and within – US states. This, too, aligns with differences in regional climate.
Hotter states in the US south have near-universal AC access. But in Washington, a north-western state with a climate more comparable to that of western Europe, 66% of people have AC in their homes.
Some European nations have ‘resisted’ AC – but its popularity is growing
International commentators have written extensively about Europe’s “longstanding resistance to cooling technology”, especially when compared to the US.
Newspaper editorials in the Washington Post and the Wall Street Journal, alongside numerous op-eds and blog posts, have added fuel to this “culture war”. Elon Musk has even promoted an AI-generated message stating that Europeans “should just install AC”.
Often, European attitudes are attributed to “guilt” about AC’s energy demand, “cultural conservatism” or “overbearing governments”. One commentator ascribed divergent attitudes in Europe and the US to “different ideas about physical suffering and sacrifice”.
Meanwhile, right-leaning commentators and climate-sceptic groups have blamed “climate policies, which view AC as an unnecessary luxury”.
In general, these critiques often fail to consider the most obvious explanation, which is that AC adoption is low in northern Europe because the historical climate made AC unnecessary.
Critical articles have instead drawn attention to restrictions on AC use in some European countries, as well as the lack of support for AC in official heatwave guidance.
For France, in particular, polling has indeed highlighted widespread disapproval of AC, both on environmental grounds and due to alleged health impacts. Such messages have also been voiced regularly in French media and by left-leaning and green politicians.
However, across Europe there are plenty of signs that such attitudes are shifting, following successive spells of extreme heat.
Amid the June heatwave, there were reports from Germany, France and the UK of “skyrocketing” AC sales. This surge was even acknowledged by the foreign ministry in China, due to the nation’s role in supplying many of these products.
The shift is taking place in politics as well. Marine Tondelier, leader of the French Green party – which has traditionally opposed AC – recently stated that “there are places where we just can’t do without AC anymore”.
Overall, AC has been on the rise across Europe, with France, Spain and the Netherlands all using more than twice as much energy for AC and other “space cooling” technologies in 2024 as they did in 2015.
AC production in Germany has also risen by at least 75% in recent years and a growing share of German homes are being built with it installed.
Notably, there is little evidence that “climate policies” are blocking Europeans from installing AC. Polling in Germany shows that, while people are concerned about environmental impacts, the high costs of installing and running it are perceived as greater barriers.
Finally, there is an important distinction between individual AC units in people’s homes and installing them in public spaces, such as hospitals, care homes and schools.
While neither is widespread in France, support for the latter can increasingly be found across the political spectrum, from Greens to the far-right National Rally (RN).
AC emissions are growing, but its climate impact could be limited
Some people have noted that a wider rollout of AC in Europe could drive up emissions.
As noted in the Financial Times by columnist and chief data reporter John Burn-Murdoch, there is a logic to this argument, “at least superficially”. He writes:
“AC uses a lot of energy; if the proposed defence against emissions-driven global warming means emitting more, then we have an obvious problem.”
The emissions impact of AC depends heavily on the generation mix of a country’s power sector.
According to the International Energy Agency (IEA), “space cooling” – mostly AC, but this does include some fans – used 2,100 terawatt-hours (TWh) of power globally in 2022.
As such, it was responsible for 1bn tonnes of carbon dioxide (CO2) from electricity use globally. This equates to around 2.7% of total CO2 emissions globally from fossil fuels and industry.
(As well as indirect emissions through power use, AC units can also directly release greenhouse gases – used as AC refrigerants – when they leak or are improperly disposed of. Following the 2016 Kigali Amendment, countries are progressively trying to phase down the use of potent greenhouse gases in AC units.)
In a LinkedIn post, Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air and regular Carbon Brief contributor, says:
“There is a lot of alarmist messaging about how much electricity AC uses. However, on an annual basis, the demand is not that substantial. Currently, AC uses about 1% of electricity in the EU and catching up to adoption rates in the US would double this.”
According to the IEA estimates from 2018, “if left unchecked, energy demand from AC will more than triple by 2050”, reaching 6,200TWh of power.
By mid-century, households would contribute the most to the increase (70%), with at least two-thirds of the world’s households potentially having AC, according to the Paris-based agency.
Decarbonising electricity grids and energy-efficiency improvements can reduce AC emissions and their impact on climate.
For instance, in countries with a low-carbon electricity mix – such as France, where nuclear energy accounts for 67% of its electricity generation – expanding AC would have a more limited climate impact than in other countries.
In countries such as India, there could be a more significant increase in emissions as AC is adopted, due to the role coal plays in the country’s energy mix, especially during the night. Demand is growing fast – following low access historically – and many AC units are inefficient, with high electricity use.
According to a new working paper from the India Energy and Climate Center (IECC) at the University of California, Berkeley, “room AC” – portable plug-in units, as opposed to those permanently installed in buildings – already accounts for nearly one-quarter of India’s peak electricity demand (60-70GW) – and this is before the majority of Indian households have bought their first AC unit.
Dr Nikit Abhyankar, co-faculty director of the IECC, tells Carbon Brief that, as AC use is expanded across the world, it should be paired with solar and battery storage, where the “economics have completely shifted” in the last few years. This will help to cut both energy bills and emissions.
According to the IEA, accelerating energy efficiency improvements could deliver more than one-third of all CO2 emission reductions between now and 2030.
The global energy demand needed to run ACs alone in 2050 could be reduced by 1,300GW – the equivalent of all of China and India’s coal plants – through energy efficiency measures, it estimates.
Aditya Valiathan Pillai, a climate adaptation researcher at King’s College London, tells Carbon Brief that, as the use of AC expands, there is a conversation to be had about where and “what type of technology [is used] and who gets access” to it.
A final point is that many AC units are air-to-air heat pumps, which can efficiently heat homes, as well as keeping them cool. As such, wider AC adoption could boost the adoption of electrified heat, helping to cut emissions from gas boilers.
Heat from AC can contribute to directly warming cities
Some critics of AC mention its electricity demands and associated CO2 emissions from fossil-fuel combustion, which contribute to raising the temperature of the entire planet. (See: AC emissions are growing, but its climate impact could be limited.)
But AC also has a localised impact. It works by removing heat from indoor air and pushing it outdoors, raising temperatures on the street and exacerbating the “urban heat island” effect.
Left-leaning French politicians are among those citing this as an argument against AC, particularly in cities. Indeed, Emmanuel Grégoire, the Socialist mayor of Paris, appeared to be making this point in an interview with Le Monde, during the June heatwave:
“[AC] can be useful for cooling collective spaces and protecting the most vulnerable populations, but individual AC is a scourge – it makes the problem worse by heating the city even more.”
One study concludes that, in a city such as Phoenix, Arizona, where the technology is widespread, AC use during a heatwave can raise night-time temperatures by 1-1.5C.
Another models a nine-day heatwave in Paris – in a future with “massive” AC use – and finds an increase in external temperature of more than 2C, due to heat emitted by the units.
Given this, some scientists argue that AC can be a form of climate “maladaptation” – referring to actions that backfire and make people more vulnerable to global warming.
The Intergovernmental Panel on Climate Change (IPCC) has highlighted this issue, concluding:
“AC may constitute a maladaptation because of its high demands on energy and associated heat emissions, especially in high-density cities.”
Compared to the US, more people in Europe live in dense, urban areas. According to Dr Vincent Viguié, a climate change economist at École des Ponts ParisTech, this could leave Europeans more exposed to heat from AC units. He tells Carbon Brief:
“If you live in a neighbourhood that is not dense, like in a suburban neighbourhood or in the countryside, you don’t care about this…So, once again, there is a key difference between US and European cities.”
Viguié is among the experts arguing that other climate-adaptation measures should be considered alongside AC, to keep entire cities cool – not just individual homes. He says:
“It’s not to say that the heat released by AC by itself is a reason to forbid AC…It’s just that not taking that into account may lead to bad decisions.”
More AC could help to reduce heat deaths in Europe
Heatwaves can be deadly, especially for older or vulnerable members of society.
According to climate scientists at World Weather Attribution, “heatwaves cause more deaths in Europe than all other natural hazards combined”.
The heatwave in June 2026 is estimated to have killed more than 20,000 people in Europe. In France – which has seen some of the hottest temperatures – the heatwave caused more than 2,700 heat-related deaths, according to analysis published by Carbon Brief.
AC does help to protect people from the effects of extreme heat. A 2021 study found that globally, AC averted an estimated 190,000 heat-related deaths annually during 2019-21.
With its much higher penetration of AC, the US has fewer deaths due to extreme heat than Europe.
Heat kills around 11 people out of every 100,000 in Europe, compared to around two people in the US, according to analysis by data scientist Dr Hannah Ritchie from Our World in Data.
Several publications have pointed out that “Europe’s heatwaves are deadlier than American gun violence”. While this is technically accurate in absolute terms, Ritchie says the comparison is “a bit silly” for a number of reasons, not least because on a per-capita basis, US gun deaths are higher.
However, experts suggest that AC is only one part of a wider effort to protect people from extreme heat.
A 2020 study looking at heat-related mortality in Canada, Japan, Spain and the US, found that excess deaths due to heat decreased between 1972 and 2009.
For example, the proportion of deaths due to extreme heat fell from 1.7% to 0.5% over the period in the US and 3.5% to 2.8% in Spain.
However, an increase in AC only explained 16.7% of the drop in the US and 14.3% in Spain.
The research concludes that “other factors have played an equal or more important role in increasing the resilience of populations”. This is supported by research that shows changes to cities, such as planting more trees, as well as behavioural shifts and public-health measures, can all protect people from dangerous heat.
Additionally, across Europe there is already a range of policies and measures in place to protect the most vulnerable from heatwaves. Many of these were brought in following the unprecedented summer of 2003, when 70,000 died from extreme heat.
These policies were highlighted by French environment minister Agnès Pannier-Runacher, in response to the far-right National Rally (RN) party’s AC proposals:
“The incompetent RN has just found out that nursing homes need air-conditioned rooms. Thank you, but it’s actually been mandatory since 2004.”
Another study found that measures that have already been rolled out in France would cut the projected death toll of a 2003-like heatwave by more than 75%. This is in part due to the expansion of AC in places such as nursing homes, but also other approaches, such as heat action plans.
For example, France has a multi-tiered action plan, which includes local governments ensuring access to cooled spaces and water, keeping a list of vulnerable individuals for targeted interventions, as well as national information campaigns.
According to the UN’s office for disaster risk reduction, this French plan has led to a “significant reduction in heat-related mortality”.
While action plans have proved successful in a number of nations, less than half of European countries have such a plan in place.
‘Net-zero rules’ are not blocking AC installation in the UK
In the UK, Conservative politicians and right-leaning media have tried to pit the adoption of AC against net-zero policy.
Writing in the climate-sceptic Daily Telegraph, columnist Matthew Lynn claimed falsely:
“Strict net-zero rules now mean that aircon is effectively banned in the UK.”
(Further down the article, he concedes: “AC is not strictly speaking banned in new-build homes in the UK. But tough environmental rules mean that it is very hard, and expensive, to install in practice.”)
The same narrative has been used in articles by GB News, the Sun and others. A separate article in the Daily Telegraph’s “money” section goes further, claiming that AC had been “torn from homes under net-zero clampdown”.
A blog post from the Ministry of Housing, Communities and Local Government rebuts these claims, stating:
“There has been media coverage this week suggesting that AC is banned in homes. This is incorrect.”
For the UK, while it is true that fewer than 5% of homes currently have AC, this is largely due to the fact that it was not hot enough in the past to warrant the expense. Historically, the focus has therefore been on keeping buildings warm, rather than cool.
Extreme heat has previously been rare in the country, so homes were built with insulation and other measures to keep heat in during the “dank winters”. (See: Much of Europe has not needed AC in the past.)
Current regulations do not ban the installation of AC outright. However – as the government’s blog post notes – there is no blanket rule, meaning there are some localised differences.
Certain areas – or certain kinds of properties – may be subject to additional complications for installing AC.
In a 2025 video on Instagram, shadow secretary of state for energy security and net-zero Claire Coutinho referenced the London plan, for example, which is a framework for development in the capital launched in 2021. She said:
“[London mayor] Sadiq Khan says no. The London plan says we shouldn’t have air con because it uses too much energy. But this is mad! This is a poverty mindset that we need to get away from.”
The London Plan does not stop homes from having AC. It simply says that, for new buildings, passive design measures should be prioritised, such as the orientation of the building, the window design and incorporation of measures such as external shading and trees.
A recent response from the mayor added further measures, such as the need to “minimise the necessity for the operation of mechanical measures including AC, which would further add to the heat island effect within urban areas and add operational cost to residents”.
Elsewhere, new-build homes across England must meet the requirements of “part O” of the 2022 building regulation updates. This includes addressing overheating in buildings through energy-efficient design and prioritising passive cooling, with AC as a last resort.
For existing buildings, most AC units fall under “permitted development rights”, meaning no planning application is required to install them.
Additionally, regulations were relaxed in 2025 to make it easier to install an air-to-air heat pump – which can both heat and cool air – without planning permission.
This means that, far from blocking the expansion of AC, net-zero policy has made it easier to install specific cooling systems.
Speaking to Carbon Brief, Andrew Sissons, director of sustainable future at Nesta, says the government must now implement its announced £2,500 subsidy for air-to-air heat pumps “as quickly as possible”, to further ensure that the technology can be rolled out efficiently. He adds:
“[The government] should also continue to expand permitted development rights for air-to-air heat pumps, with a particular focus on flats and homes in denser areas. As long as heat pumps meet the MCS [Microgeneration Certification Scheme] noise test, there are few reasons to limit their use via the planning system.”
Some properties, such as large homes, listed buildings or those in conservation areas, may still require planning permission to install an air-to-air heat pump or other AC. Sissons notes that this can add cost and delay to installation.
While it cannot be said that AC has been blocked or banned due to net-zero, neither has it been prioritised.
This may shift as temperatures continue to rise. UK government advisors at the Climate Change Committee (CCC) suggest that 22% of the UK’s housing stock will likely need active cooling, such as AC, to cope with 2C of global warming.
The CCC’s recent adaptation report also calls for all new homes to be built using low-cost, passive cooling measures, alongside more AC.
Active cooling such as AC is more likely to be needed for retrofitting existing homes, the report adds.
AC is not the only answer to overheating cities
AC has become increasingly politicised in Europe, as demonstrated by France’s RN party announcing its “grand plan for AC” in all public buildings.
As noted by Dutch MEP Gerben-Jan Gerbrandy, this “far-right” embrace of AC is coming from the same people who for years have “delayed emissions reductions”.
In response, left-leaning policymakers in Europe have frequently downplayed the role of AC, prioritising programmes of urban greening and retrofitting older buildings.
Such approaches for dealing with extreme heat have already proved successful. Therefore, many experts argue that these methods, alongside AC, will be essential to prepare for a hotter world.
According to the IPCC’s sixth assessment report, adaptive infrastructure, such as urban forests and green roofs, can reduce energy use because of cooling, with co-benefits for climate, air quality, physical and mental health.
While retrofitting older buildings for heat as well as insulating them from the cold might prove challenging, urban greening and an active shade policy – one that determines how much of every street is exposed to direct sunlight – are simple measures cities can adopt.
Some experts have also warned about the high cost of running AC, expressing concerns that excessive reliance on the technology could increase energy poverty.
In a Carbon Brief guest post published in 2025, researchers at the Basque Centre for Climate Change found that framing AC as the “default solution” can miss the opportunity to design “more inclusive, human-centred responses” to rising temperatures.
William Lewis, a PhD candidate and one of the guest post’s authors, tells Carbon Brief it is not a case of “one or the other”, when considering AC and other options:
“We have this opportunity in European countries to choose a slightly different path [from the US], which isn’t AC in every single home.”
King’s College London’s Pillai says that, by centring the debate on AC, the far-right response to the heatwaves in Europe has “completely neglected the science of how you cool human beings”.
There are many solutions, he adds, that are already widely used across hot developing countries, such as ceiling fans, windows that open and cross-ventilation, as well as strategies to reduce cumulative hours of heat exposure.
Pillai tells Carbon Brief that, while places reaching 42C and higher “definitely need to think about AC very seriously”, places in the “low to mid 30Cs” could rely on these alternatives.
Behavioural change, he adds, is the “least glamorous part” of heat policy, but “pulls most of the weight” of protecting people. These include a wide range of actions and responses – from reducing heat exposure, to wearing lighter clothing and drinking more water and fluids.
There are also workplace protections. Pillai tells Carbon Brief that these could include legislation on mandatory work breaks, cooling and shade requirements at workplaces, as well as health insurance that covers heat stress days that have been lost by heat-exposed workers.
