Faster electrification is the best way to secure lower energy bills and stronger energy security, according to the Climate Change Committee (CCC).
The government’s official climate advisers have stressed the importance of electrification, noting that electric cars and heat pumps can “put money back into people’s pockets”.
Moreover, the UK’s net-zero targets face “significant risks” unless there is faster progress in electrifying cars, heating and industry, according to the CCC’s latest progress report
The report notes that the government has closed some of the gaps to its upcoming targets and introduced more “credible” plans.
However, challenges remain in the UK’s climate strategy, including accelerating the expansion of heat pumps, cutting emissions from farms and supplying planes with “sustainable” fuels.
The CCC notes that 17% of the emissions cuts required to achieve the UK’s 2030 Paris Agreement climate target are currently not addressed by any government plans at all.
Amid political and industry pressure, the committee also says the government should “stand firm” on its climate goals, including its strategy for encouraging electric-vehicle (EV) sales.

Overall progress
Today’s progress report is the third since Labour swept to power in 2024.
It arrives amid a “red extreme heat warning”, on the day that parliament will vote on the seventh “carbon budget”, a legally binding limit on UK emissions in 2040.
The report comes at a febrile moment in UK politics, with prime minister Keir Starmer having just resigned and with newly re-elected MP Andy Burnham widely tipped to take his place.
The opposition Conservatives and Reform are lobbying to scrap UK climate goals – and senior Labour figures want to row back on EVs and North Sea oil and gas drilling.
Against that backdrop, the CCC insists that it is the UK’s reliance on fossil fuels – and the second fossil-fuel price shock in four years – that has caused a “cost of living crisis”.
Speaking to journalists ahead of the launch, CCC chair Nigel Topping warned against any moves to weaken UK climate policies. He said:
“U-turns are really damaging to inward investment confidence…[We should] hold the course and focus on electrification…which will unlock very significant savings.”
Whereas the CCC said last year it had become “more optimistic” that UK climate goals could be met under the new government, its latest progress report strikes a more cautious tone.
It says that the UK’s emissions fell by 1.8% in 2025 and that there has been “some positive progress” in terms of delivery over the past year, but that this has been “too slow”.
There was actually an increase in emissions from transport and electricity supplies in 2025, as shown below, despite the expansion of clean power and EVs.
The UK’s greenhouse gas emissions are now roughly 50% below 1990 levels, the CCC notes, with the lion’s share of this having come from cleaning up the power sector.
In contrast, there has been far less progress in transport, which is now the UK’s largest emitter, as well as in buildings, the second largest.
The CCC stresses that future emissions cuts will need to come from using clean power to decarbonise other sectors – particularly buildings, transport and industry.
It puts a major emphasis on the need to electrify these sectors by more rapidly rolling out EVs, heat pumps and electric heating for industrial sites.
The CCC adds that government plans for meeting future targets, published last year, leave a “significant gap” to the UK’s international climate pledge for 2030. (See: Policy gaps.)
The electrification ‘prize’
The most striking aspect of this year’s report is the way it centres on electrification, which the CCC says has been given “insufficient focus” to date.
Electrification has shot up the agenda in recent months, with the COP31 presidency calling for countries to back a global goal for 35% of “final” energy to come from electricity by 2035.
The text of the CCC’s latest report uses the word “electrification” far more often than previous editions, as shown in the figure below.
Early last year, in advice on the seventh carbon budget, the committee singled out electrification as key to cutting UK emissions. It said electrification had won out over alternative options, thanks to rapid cost reductions for technologies such as EVs.
Now, the CCC says that electrification is also the best way to secure lower energy bills, stronger energy security and a host of other benefits.
Topping said these benefits include “putting money back into people’s pockets”, but also cleaner air, stronger energy security and protection from fossil-fuel shocks:
“The prize is really significant here. By 2030 alone, the UK could save up to 80m barrels of oil and 1.5bn therms of gas each year. That would cost almost £8bn at current oil and gas prices.”
The emphasis on the topic is also clear in the CCC press release for its report, which is titled: “Faster electrification would cut UK household bills, say climate advisers.”
The report fleshes this out in a dedicated chapter that explores the financial benefits of electrifying household energy use, including heat and transport.
Topping said that the “home of the future” will be equipped with an EV, a flexible “time-of-use tariff” for its electricity supplies and a heat pump for keeping warm.
Moreover, the report shows that even today, this type of household would cut its annual energy bills by around £1,200, relative to using a petrol car and a gas boiler.
Crucially, this saving, shown in the figure below, includes the high upfront costs of installing an electric heat pump and solar panels. The analysis shows that electrified homes have far lower annual running costs, which easily outweigh this initial outlay.
(Due to “modelling limitations”, the CCC analysis does not consider home batteries, which can help unlock even larger savings.)
The CCC says that while not everyone is currently in a position to enjoy the financial benefits of electrification, its analysis points to savings both before and after the Iran crisis, as well as for high- and low-income households, with the latter eligible for grants to cover upfront costs.
Even more homes would be able to unlock these benefits if the government acts to resolve barriers, such as high public charging costs, says the CCC.
However, the report says that the government’s current plan to electrify the economy “lacks ambition” and that there are “worrying signs” in some areas, such as heat pumps and electric vans. (See: Road transport and Buildings.)
Ultimately, says the CCC, the best way to encourage faster and wider electrification is to make electricity cheaper. This has been its top recommendation for several years.
Policy gaps
Since the last CCC progress report, the government has published a new “carbon budget and growth delivery plan” (CBGD), explaining how it will cut emissions in the 2030s.
The CBGD “projects slower emissions reductions for surface transport and buildings compared to the previous government’s plan”, according to the CCC.
This reflects both the slow rollout of some technologies – such as heat pumps – and “areas of reduced policy ambition”, including less support for low-income homes to install insulation.
The CCC says that without “sufficient progress on electrification” this year, the UK’s 2030 emissions target “may become out of reach” and future goals would face “significant risks”.
The chart below demonstrates the CCC’s view that the UK is “well on track” to meet its fourth carbon budget, between 2023 and 2027, and that there are “credible policies in place” to meet the fifth carbon budget out to 2032.
However, it also shows the “significant gap” that the CCC says still exists between projected emissions cuts (blue lines) and the UK’s international climate target for 2030, its nationally determined contribution (NDC) to the Paris Agreement (black circle).
(This is particularly notable as the NDC was the first official UK climate goal that was aligned with its 2050 net-zero target. The fourth and fifth carbon budgets were set before the net-zero goal and therefore need to be overachieved.)
Plans that are “credible” or only come with “some risks” are on track to cut emissions to 356m tonnes of carbon dioxide equivalent (MtCO2e) by 2030. This is 11MtCO2e lower than last year, but still a shortfall of 64MtCO2e.
Overall, the CCC says there are “credible” plans in place for 44% of emissions reductions by 2030, including those linked to renewable energy, EV sales growth and electrification of steel production at Port Talbot in Wales. Another 15% of reductions come with “some risks”.
The report concludes that there are “significant risks” attached to 19% of emissions cuts, including the expansion of heat pumps, future “sustainable aviation fuel” (SAF) supply and agricultural policies.
There are also 4% of required emissions cuts for which the UK has “insufficient plans”, including much of the electrification of the UK’s heavy industry.
The chart below shows how this assessment compares to previous CCC analysis of government plans, with the share of “credible” government plans increasing.
(As the latest report is based on the new CBGD rather than the previous 2023 plan, the assessments have different levels of baseline emissions and are not directly comparable. However, this chart shows the rough direction of travel.)
As the chart shows, a substantial chunk of the required emissions cuts need to meet the 2030 pledge – 17% of the total – are not covered by the CBGD.
This reflects the fact that the new plan simply does not achieve the 2030 target, according to the CCC, despite the government’s stated commitment to its NDC goal.
(The government’s plan had also acknowledged that it fell short of meeting the 2030 NDC.)
The CCC emphasises that “the government will need to bring forward additional policies and plans to make up this gap”.
The new report suggests several areas – including faster EV growth, more heat-pump installations and more ambitious recycling rates – that would close 17MtCO2e of the 26MtCO2e gap to the 2030 goal.
Unlike the 2030 NDC, the government’s plan does achieve the sixth carbon budget, between 2033 and 2037. However, the committee says “this is largely achieved through additional measures where we have assessed there to be significant risks or insufficient plans”.
Only around three-fifths of the required emissions cuts for the sixth carbon budget are covered by “credible” plans or plans with “some risks”.
According to the CCC, the government is relying on a rapid scale-up of engineered removals beyond 2030, but has provided little detail about how it will achieve this. (See: Other sectors)
“This approach carries substantial risks,” according to the committee.
Road transport
Road transport remains the UK’s highest emitting sector and its emissions increased by nearly 3% last year, according to provisional data in the CCC report.
Electric-car sales have continued increasing, reaching nearly a quarter of new sales last year. The number of electric cars on the road surpassed 2m in May 2025.
However, the emissions benefit of this rollout of electric vehicles (EVs) “is likely to have been offset by other factors”, such as driving rates returning nearly to pre-Covid levels, according to the CCC.
The report notes that EV costs “continue to fall” and have met price parity in some parts of the market, with grants providing an extra boost to sales.
The committee’s pathway to net-zero assumes faster emissions cuts from road transport than the government’s pathway. This is largely because it assumes an imminent “tipping point” will be reached, when EVs reach upfront price parity with petrol cars.
Nevertheless, the report says that sales will still “need to accelerate fast” over the next few years and that this will require consistent government support.
The CCC stresses the “key role” of the zero-emission vehicle (ZEV) mandate, which requires manufacturers to sell a rising share of EVs.
There have been reports that the government is planning a “U-turn” after a review of the ZEV mandate. The CCC says it is “essential” that the review “does not lead to further concessions”:
“Doing so would severely undermine prospects of achieving the UK’s 2030 NDC, exacerbate the UK’s dependence on imported oil, and leave more households paying the higher costs of petrol or diesel cars.”
As well as “stand[ing] firm” on the ZEV mandate, the committee says it is important that the government “remove[s] barriers to EV adoption”.
One key policy highlighted by the report is increased access to cheap EV charging, so the one-third of UK homes without off-street parking access can “benefit from lower running costs”.
(CCC analysis suggests that while the average home would save at least £660 a year by switching from a petrol car to an EV, their running costs could actually increase if they have to rely on public charging infrastructure.)
The report also stresses the use of EV “time-of-use tariffs”, which it says can help people save even more money. It notes that “measures to support consumer awareness” of this “could drive further uptake”.
Also, with a new 3p per mile EV tax due to start from April 2028, the committee says it is “essential that this new tax is implemented in a straightforward manner” to minimise the “hassle factor” that could disrupt the EV transition.
While electric-car sales have so far remained slightly ahead of the level needed to hit the ZEV mandate, the CCC notes that both electric van sales and prices are “significantly off track”. Unlike cars, electric vans still cost considerably more than their combustion-engine equivalents.
The committee says government support, including improved access to fast charging and “regulatory reforms”, is also “key”. As an example of the latter, it notes that certain licensing and testing requirements are based on vehicle weight, which puts heavier battery-powered vehicles at a disadvantage.
Finally, the CCC criticises recent policy decisions that incentivise sales of plug-in hybrids (PHEVs) “based on emissions factors which underestimate real-world emissions”. It notes:
“Providing incentives for emissions savings that PHEVs do not deliver distorts the market and risks eating into the demand for EVs.”
Buildings
The CCC says that the rate of growth in heat-pump installations in homes slowed last year, rising just 7%, compared to the 56% jump seen in 2024.
Around 52,000 heat pumps were installed in 2025, according to the report. Of these, 31,200 were installed with the support of grants from the “boiler upgrade scheme”.
This was not enough to meaningfully reduce emissions, says the CCC, only delivering around 0.1MtCO2e of extra savings in 2025.
(To eliminate emissions from homes by 2050, heat pump installations in existing homes need to reach 1.4m per year by 2035, according to the CCC.)
Overall, emissions from the buildings sector fell by 1.2MtCO2e in 2025, amounting to a reduction of 1.3% for non-residential and 1.6% for residential buildings compared to 2024.
This was despite the winter months being colder in 2025 than the previous year, generally meaning greater heating demand. This suggests factors other than weather are driving the reduction, it says, such as higher energy prices leading to lower heating use.
The CCC notes that while emissions did drop, this “does not indicate progress on decarbonising home heating”. It adds:
“Without further actions to decarbonise buildings, it is likely that emissions will rebound if energy prices fall or weather conditions revert to average.”
The slowdown in the rate of heat pump installations was largely due to the closure of the ECO scheme, which delivered around one-third of heat pump installations in existing homes over the last three years.
In terms of government policy, the CCC notes that there has been some “positive progress” for buildings, due to the new “warm homes plan” and the “future homes standard”.
The former provides support to help people install electric heat pumps, rooftop solar panels and insulation. In total, 5m homes are expected to benefit from £15bn of grants and loans earmarked by the government for these upgrades by 2030.
While installation rates in the UK in 2025 were significantly below this level, the CCC report says that growth rates in other European markets – and indeed, in the UK between 2023 and 2024 – suggest that higher rates could be achievable.
The CCC notes that while there is £1bn a year earmarked for supporting upgrades of low-income households under the warm homes plan, this is still a “significant decrease in investment” from that provided by ECO.
The future homes standard, meanwhile, is an update to existing regulations in England. From March 2028, new-build homes in England will be required to have on-site renewable energy generation and a low-carbon heating system.
From then on, newly built homes will produce 75% less greenhouse gas emissions than under previous regulations.
The CCC report notes that the installation of heat pumps in new homes, specifically, is currently on track to achieve targets, with 25% of new homes built with a heat pump in 2025. However, it says retrofit installations of existing homes are significantly below where they need to be and “urgently need to accelerate”.
The CCC notes that while there has been some progress in removing policy costs from household electricity bills, the ratio of electricity to gas prices remains a major barrier to heat pump take-up. (See: The electrification ‘prize’.)
It also notes that there has been no action to address this barrier for non-residential buildings.
Fewer than 2% of homes have a heat pump in the UK, it says, placing the nation among the lowest rates of installation in Europe, as seen in the chart below.
Industry
Industry accounted for the largest share of emissions reduction in the UK in 2025, according to the CCC, with a 5.4MtCO2e (12%) drop from 2024.
As such, sectoral emissions for industry are now 56% lower than they were in 2008.
This was largely due to the closure of blast furnaces at the Port Talbot steelworks towards the end of 2024, ahead of reopening with new electric arc furnaces. Emissions from iron and steel production therefore fell by 3.2MtCO2e year-on-year in 2025, according to the CCC report.
The rest of the reduction was due to a fall in the output of energy-intensive, which the CCC says is in line with the longer-term trend in UK manufacturing seen since the 1990s.
However, the CCC notes that while some specific progress has been made to decarbonise industry, barriers to further progress remain.
It urges the government to set a clear plan for how electrification can become the economically rational choice for a wide range of industries.
As for buildings, the CCC points to the high electricity prices, relative to gas, as a major barrier to the decarbonisation of UK industry.
Carbon capture and storage (CCS) has taken some “positive steps”, according to the report. This includes the government allocating £9.4bn of funding to support its development.
There has also been a final investment decision for the first CO2 storage facility at a UK manufacturing site and the construction of transport and storage infrastructure for the nation’s first CCS industrial “clusters”.
Fossil fuels
The CCC’s report states that “many countries are responding” to the current global energy crisis triggered by the Iran war by “rapidly reducing dependency on fossil fuels”.
It continues that emissions from the UK’s fossil-fuel supply sector fell by 1.5MtCO2e in 2025, in line with the “significant historical decline seen over the last three decades”.
Emissions in the sector are now 45% lower than 2008 levels, it adds.
Key drivers of emissions decline from 2024-5 were a fall in emissions from oil refining of 0.9MtCO2e, mostly due to the closure of Grangemouth and Prax Lindsey refineries in 2025, according to the CCC.
Declines in production emissions associated with oil and gas were due to the closure of North Sea fields “as they reach the end of life”, says the report.
It adds that this is a “continuation” in a longer-term trend. Production emissions from oil and gas have fallen by 58% since 2008 and by 75% since their peak in 2000. The CCC continues:
“The decline in oil and gas production is expected to continue as oil and gas reserves in the mature North Sea basin are increasingly depleted – the NSTA [North Sea Transition Authority] projects a further decline in combined oil and gas production of 93% by 2050.”
The report does not directly address the Labour government’s policies on oil and gas production in the North Sea.
Labour has ruled out new oil and gas licences – a manifesto commitment that has been subject to intense lobbying from the oil and gas industry and right-wing media. (See Carbon Brief’s factcheck on nine false or misleading myths about the North Sea.)
However, the government has indicated it might approve new projects that already have a licence, if they can pass an environmental impact assessment that will consider the emissions from burning the oil and gas produced.
Speaking at a briefing for journalists, CCC chair Nigel Topping noted that oil and gas production is projected to continue to plummet in the coming decades, regardless of whether the government issues new drilling licences, adding:
“The real road to energy security is not through some marginal drilling decisions, but through electrifying the economy.”
Electricity
Emissions from electricity supply rose in 2025, following a 5% increase in unabated gas generation year-on-year.
According to the CCC, this offset the reduction in emissions from coal, with the closure of the UK’s last coal-fired power plant in 2024.
This is in line with Carbon Brief’s analysis from January, which similarly found that there was a small increase in emissions per unit of generation in 2025.
This bucks the trend seen in the UK since 2008, over which period emissions from electricity supply have fallen by 82%.
The CCC says the rise in gas generation was likely due to a combination of factors, including a 12% drop in nuclear generation, an 11% decrease in net imports, underutilisation of wind capacity due to grid constraints and lower-than-average wind capacity additions.
Last year, offshore wind capacity increased by 0.7 gigawatts (GW), bringing the UK’s total to 16.6GW, according to the CCC.
This is expected to more than double to around 37GW by 2032, once the existing pipeline of new projects is built – including those that secured subsidies in the most recent auction for “contracts for difference” (CfDs).
The CCC notes, however, that further additions will be needed to reach the government’s “stretching goals” for offshore wind.
An additional 0.3GW of onshore wind capacity was added in 2025, bringing the national total to 16.4GW. It says between 2.1GW and 2.5GW will need to be added annually up to the end of the decade to meet government targets.
The UK installed more solar capacity in 2025 than in any year since 2015, adding 2.8GW to bring the national total capacity to 21.7GW.
To reach government targets, the CCC says installation of solar power still needs to increase, with around another 5GW required by the end of this decade.
The CCC highlights that faster progress is needed on expanding and modernising electricity networks, as well as deploying storage.
For example, in 2025, some 9.4 terawatt hours (TWh) of wind generation was “curtailed” – when windfarms are paid to turn off – up 77% on 2024.
Agriculture and land
The CCC’s report says “emissions in agriculture and land use have not fallen significantly in recent years” and that progress addressing this has been “too slow”.
Cattle and sheep numbers fell by 1% and 2% respectively in 2025, continuing a longer-term trend, with livestock numbers at their lowest since 1990, says the report.
This has led to a reduction in methane emissions from 2022-24, but this was offset by an increase in CO2 emissions in these sectors. It continues:
“This was in part driven by a smaller forestry sink due to an ageing woodland profile and removal of trees for habitat restoration priorities.”
The report adds that household beef and lamb purchases fell by 5% in the last year and have dropped by 9% since 2021, likely “driven by high beef and lamb prices and cost-of-living pressures”.
It continues that one area of “positive progress” is an increase in peatland restoration rates.
Some 21,400 hectares of peatlands were restored in 2025 – a 26% increase on the previous year and around three times the level in 2020, according to the CCC.
It adds that there is grant funding in place for peatland restoration across the country “until at least 2027”.
Tree-planting has seen “more mixed” progress, says the report. Planting rates fell by 25% from 2024-5, following a large boost to forest creation the year before.
The reduction was “driven by funding cuts in Scotland, which continues to lead in the establishment of new woodlands for the UK, planting more than half of the total in 2024-25”, says the report.
It adds that planting rates increased in England and the Department for Environment, Food and Rural Affairs (DEFRA) is expected to launch a woodland creation strategy this year.
Despite this mixed progress, the chart below shows how the UK government is “on track” on most key agriculture and land use indicators, when compared to the CCC’s central pathway to net-zero and the government’s own ambitions.
The report says that another area of “positive progress” is the publishing of England’s long-awaited land-use framework in March of this year.
The framework used “high-resolution modelling” and found that there is enough land in England to meet climate and nature goals, while also producing more food and building new homes.
To increase progress, the report says that the government should “put policies and incentives in place to ramp up tree-planting and peatland restoration”.
One key upcoming policy development will be the “25-year farming roadmap”, the government’s long-term direction for farming in England. This is due to be published later this year, according to the CCC.
Aviation and shipping
Emissions from flights fell by 0.5% in 2025, despite a 3% increase in overall distance flown by UK passengers.
The CCC says this is likely due to fuel-efficiency improvements within the nation’s aircraft fleet and “a small contribution” from the use of “sustainable aviation fuel” (SAF).
The report concludes that fuel-efficiency improvements are “almost on track” compared to the CCC’s net-zero pathway. The share of jet fuel provided by SAF reached 2.5% in 2025, which is above the level set by the government’s SAF mandate.
While people flew more last year, the overall distance travelled via planes is still below the projected levels in the CCC’s pathway for 2025.
The committee says emissions growth from aviation has “slowed down”, but notes that “it is too early to say whether aviation emissions will grow, plateau or decrease in the future”.
Overall, the CCC says there has been “mixed progress” in the aviation sector. This year’s SAF Act included a mechanism designed to drive domestic production of SAFs, but the report stresses that “significant challenges remain around scaling up supply”.
Meanwhile, for the first time, the government plans to use international carbon credits under CORSIA – the UN’s aviation emissions scheme – to deliver its sixth carbon budget. According to the CCC:
“This introduces significant risk, including uncertainty over the availability and quality of high-integrity credits.”
As for shipping, the CCC says this has seen “limited progress”. It welcomes the inclusion of domestic shipping in the UK emissions trading scheme (ETS) as “an important step”, but points out that this is only a small fraction of the sector.
Most emissions come from international shipping. The committee says delays to the International Maritime Organization’s (IMO) net-zero framework – following opposition from the US and big fossil-fuel producers – has “significantly increased” the risk of hitting emissions targets for this sector.
Other sectors
The CCC report highlights “significant risks” with the use of engineered removals in the coming years.
The government’s plan for achieving emissions targets over 2033-37 relies on a “rapid ramp-up” of technologies that suck CO2 out of the atmosphere, the report says, but there is still a lack of detail on how this will be achieved.
During this period, the amount of CO2 removed through these technologies is expected to reach an average of 17.4MtCO2e per year.
But the CCC says that 94% of removals planned for 2033-37 have “significant risks or insufficient plans”.
There is greater confidence in achieving planned removals over 2028-32, the report says, but this is due to scaled-back plans and policy progress.
The CCC says it is “essential” for the government to develop a strategy for delivering and monitoring engineered removals, along with “sufficient contingency plans…for any shortfall”.
The report also looks at emissions from waste, which are expected to reduce by an average of 1.1MtCO2e per year between 2024 and 2037.
The CCC has greater confidence in the government’s ability to meet waste goals compared to last year’s assessment.
But the report notes that there has been “little improvement” in recycling rates in UK homes. It says that further policies will be needed to meet plans to reduce waste, boost recycling and prevent waste going to landfill.
Looking at hydrogen, the CCC says there has been “good progress” in developing low-carbon hydrogen, but risks remain due to tight timelines and delays in funding.
The report mentions missed or upcoming deadlines to award contracts for some hydrogen projects and to update the UK hydrogen strategy. It notes that progress on hydrogen “must continue on the ground” in the meantime.

CCC: Faster electrification of UK will ‘put money back into people’s pockets’
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.

‘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.

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.
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
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.
