After lengthy and heated negotiations, diplomats have largely agreed on a draft framework for a new UN fund to help nations recover from the “loss and damage” caused by climate change.

Last year’s COP27 summit in Egypt marked a victory for developing nations when they secured agreement on this fund – an idea many had been advancing for decades.

A transitional committee composed of members from developed and developing countries was tasked with discussing everything from who would pay into this fund to where it would be located, ahead of a final decision due to be taken at COP28 in Dubai next month.

Meetings overran this year as members clashed over long-standing grievances. Developing countries did not want to see the fund based at the US-dominated World Bank and wanted to ensure it was accessible for as much of the global south as possible.

Developed countries wanted to see funds coming from sources besides their public coffers, including those of the wealthiest developing nations, such as China and Saudi Arabia.

In the end, the final committee meeting held last weekend in Abu Dhabi settled on a draft proposal that would see the new fund housed at the World Bank for at least four years. 

Neither developed countries nor anyone else would be obliged to pay into the fund.

This proposal will now form the basis of a final decision by leaders at COP28.

While the committee’s recommendations were adopted by consensus, a last-minute objection from the US provides an early indication that those talks at the UN’s upcoming climate summit may not progress smoothly.

What is ‘loss and damage’ and what was agreed at COP27?

Loss and damage” is a term used to describe how climate change is already causing serious and, in many cases, irreversible impacts around the world – particularly in vulnerable communities.

For example, more intense and frequent extreme weather events are causing the loss of human life and damages to properties and cropland.

The issue is recognised in Article 8 of the Paris Agreement, which says parties “recognise the importance of averting, minimising and addressing loss and damage associated with the adverse effects of climate change”. However, the Paris text did not commit countries – developed or otherwise – to providing funds for loss and damage.

At UN climate talks, the term is often used by nations and organisations to argue for developed, high-emitting nations to be held responsible for losses incurred in poorer regions, which are the least responsible for climate change. (Because of this, the term “loss and damage” is sometimes described as meaning “climate reparations”.)

At the COP27 climate summit, all countries agreed to set up a fund to pay for loss and damage. This came after a 30-year fight for such a fund led by small island states and developing countries.

After much back and forth between developed countries and the G77 and China – a major group of developing countries representing six out of every seven people in the world – a text was produced close to the end of the summit that “decided” to establish a new loss-and-damage fund.

This same text said that a “transitional committee” should be established, dedicated to coming up with a plan for how the fund would work in practice.

It added that a decision “related to the new funding arrangements” should be adopted “no later than at COP28”.

It was also decided that the committee should be composed of 24 members, including 14 members from developing countries and 10 from developed nations.

What progress has been made in setting up a loss-and-damage fund since COP27?

The transitional committee held four scheduled meetings and two workshops in Egypt, Germany, Thailand and the Dominican Republic during March-October 2023.

After the failure of the fourth meeting to reach consensus, it also held an emergency fifth meeting in Abu Dhabi from 3-4 November 2023.

The committee’s task was to come up with a series of recommendations for the loss-and-damage fund that could then be approved by leaders at COP28.

This included establishing which financial sources would feed into the fund, what kind of activities it could support and how it would work alongside existing funds. The recommendations also covered where the fund would be located and how it would be structured and governed.

Over the course of these meetings, nations and civil society groups submitted proposals for the fund. These ideas were assessed by the committee and, ultimately, fed into a series of documents that were subject to further scrutiny and debate.

As talks entered extra time in Abu Dhabi, the committee co-chairs presented members with what one of them, Outi Honkatukia of Finland, called a “take it or leave it package”. This attempted to distil all the competing views into a viable set of recommendations that could form the basis of a COP28 decision.

After passing up opportunities to object earlier on, US committee member Christina Chan raised a last-minute concern about language “urg[ing]” developed countries to support the fund.

Throughout the talks, the US had consistently pushed back against any language that compelled developed countries to pay into the fund. (While “urge” is towards the stronger end of the lexicon of UN legal drafting, it does not, in fact, imply compulsion.)

Chan asked for this text to be bracketed, indicating it had not been resolved.

The co-chairs reasoned that all members had objections to the final text for various reasons, but the committee had already reached consensus and it was too late to reopen negotiations. “Once we start bracketing, that doesn’t stop,” Honkatukia told the meeting.

Given this, Chan said the US did not view the final decision as reaching consensus. Teresa Anderson, global lead on climate justice at ActionAid International, tells Carbon Brief that the US’s “forceful objections to the transitional committee’s recommendations suggest that this text might not sail smoothly through COP28”.

Why are countries divided over the new fund?

Tensions ran high throughout the five transitional committee meetings as long-standing arguments between representatives from developed and developing nations were revisited.

Developing country committee members reportedly threatened to walk out, accusing a small group of nations – particularly the US – of pushing them into a “Faustian bargain”, involving many compromises, in order to make progress on the loss-and-damage fund.

Below are some of the key areas that sparked divisions within the committee.

Back to top

Who would receive money from the fund?

At COP27, nations agreed to create the fund to assist “developing nations, especially those that are particularly vulnerable” to climate change. However, the interpretation of “particularly vulnerable” remained a point of contention.

EU committee members, for example, suggested that the fund should only serve least developed countries (LDCs), small-island states and “other particularly vulnerable countries based on specific eligibility criteria”.

Members of the G77 and China resisted what they perceived as efforts to narrow the focus of the fund. In a statement released towards the end of the fourth meeting, Cuban G77 chair Pedro Pedroso Cuesta said:

“We must ensure that the administrative arrangements of the fund do not impede direct access to all developing countries particularly vulnerable to climate change.”

Sherry Rehman, former climate minister of Pakistan and G77 chair at COP27, told a press conference that the fund should be “more inclusive” – citing flood-struck Pakistan and Libya as middle-income nations that might not be able to access it, should more limited criteria be adopted.

The final text agreed by the committee does not specify which countries would be eligible to receive funds. Instead, it says the fund’s board would develop a “resource allocation system”, based on the available evidence and with a minimum percentage allocated to LDCs and small islands.

Who would contribute to the fund?

Currently, only a small group of “Annex II” countries, which were deemed “developed” when the original UN climate treaty was agreed in 1992, are obliged to provide climate finance.

These parties have consistently failed to meet their existing climate-finance pledges to developing countries.

However, neither the 1992 climate convention nor the Paris Agreement say who should give money to pay for climate change loss and damage.

The US and European nations have stressed the need to share the burden with wealthier emerging economies – specifically singling out China and Gulf states, such as Saudi Arabia. UK climate minister Graham Stuart told a UN ministerial meeting in September:

“It will simply not be possible to deliver what is needed if we stay trapped in outdated categories from decades ago and we must break out of this to get a positive outcome at COP28.”

Developed countries also say that scaling up the fund sufficiently would mean opening it up to contributions from non-government sources, including the private sector and humanitarian groups. (See: What options are being considered to raise money for loss and damage?)

Developing countries are not entirely opposed to drawing finance from this “mosaic” of funding sources. However, as one joint submission by committee members from developing countries states, they want to keep the focus primarily on grant-based finance from developed countries.

Referencing climate finance more broadly, the Saudi Arabian government voiced its concerns in a statement delivered at the pre-COP event in Abu Dhabi and seen by Carbon Brief. The statement said Saudi Arabia expected “those who have clear obligations to own up to them and not attempt to pass on the baton to other countries or entities outside the process”.

Brazilian diplomat Matheus Bastos, representing the G77 and China, called for language reflecting the “principles and provisions” of the UNFCCC and the Paris Agreement.

He said the function of this would be to make it clear, as those treaties do, that developed countries are obliged to provide climate finance. In the view of the G77, this extended to the “full costs incurred” in developing countries, including not only mitigation and adaptation but also loss and damage, Bastos added. The US said it would not accept this text.

Ultimately, the final recommendations would not oblige developed countries to pay into the fund. They also mention a “wide variety of sources of funding”.

Developed countries are asked to “take the lead” in providing start-up finance for the fund, rather than loss-and-damage relief.

In addition, the recommended text “urge[s]” developed countries to “continue to provide support”, while other countries would be subject to a weaker exhortation “enourag[ing]” them to do the same “on a voluntary basis”. (This is the element that the US raised its last-minute objection to as the meeting came to a close.)

Where would the fund be located?

One major issue blocking progress was the location of the loss-and-damage fund.

The US and the EU wanted to see the fund hosted by the US-based World Bank, a proposal that G77 and China members strongly opposed.

They argued that World Bank finance is based not on grants but on loans, which are not desirable for debt-burdened countries in the global south. They also said the bank is not set up to allow fast, direct access of the kind required when dealing with climate disasters.

In addition, they said it would not be accountable to all parties, due to the dominance of the US – its largest shareholder – and other major donors in decision-making.

Diann Black-Layne, a committee member representing the Alliance of Small Island States (AOSIS) said the World Bank would charge a hosting fee of 17%, which she described as “highway robbery…pure gangster behaviour”:

“[That] means that the biggest beneficiary of this fund will be the World Bank. The 10,000 employees of the World Bank will get more money from this fund than the 63 million people of the population of AOSIS countries.”

(This sum, which others have placed at 24%, refers to administration costs taken from the fund’s secretariat and is, therefore, not a portion of the total money flowing into the fund. According to the Loss and Damage Collaboration, it would amount to 1-2% of total funds.)

A coalition of nearly 70 US NGOs wrote an open letter to the US negotiating team stating that “the world does not need yet another channel for international finance that is donor-driven and unaccountable to communities in the global south”.

The World Bank issued a statement pushing back against such criticism and emphasising that it could be flexible in how it allowed countries to access loss-and-damage funds.

(This dispute recalls arguments at the 2009 COP15 climate talks in Copenhagen. There, the so-called “Danish text” – which was never adopted – would have “hand[ed] effective control of climate change finance to the World Bank”, the Guardian reported at the time.)

Developing countries argued instead for a new, independent entity operating under the financial mechanism of the UN climate convention itself.

This would be similar to the Green Climate Fund (GCF), which is overseen by a 24-person board that includes an equal number of developed and developing country representatives.

After this dispute prevented consensus at the fourth committee meeting, developing countries came to the final meeting stating that they would accept the World Bank as the host on an “interim” basis. Committee members stressed that they were making a “huge concession” in doing so.

Some developed country members also said they wanted to see a clear pathway to move the fund out of the bank within two years.

In the end, the committee agreed to a text that would establish the World Bank as an interim host of the fund for four years. It included conditions such as allowing communities to access small grants and providing access to countries that are not World Bank members.

Laura Schäfer, a senior advisor in climate risk management at Germanwatch, tells Carbon Brief that while these elements are promising, they should also be “basic conditions” for a loss-and-damage fund.

She says there remain concerns that the World Bank will end up being the fund’s permanent home, an issue that has faced other funds that were meant to be housed there temporarily:

“There is no exit strategy defined in the text, so this basically means if the World Bank performs well and fulfils all the conditions set, it will be the host even after four years.”

One of the key demands of developing countries was that, wherever the loss-and-damage fund ended up being based, it would have the status of a standalone entity under the UNFCCC. However, civil-society groups said the final language on this in the text was unclear.

The GCF, seen by some as a model for the new fund, is clearly designated as an “operating entity” under the UN climate convention’s financial mechanism. By contrast, the proposed text for the World Bank-based loss-and-damage fund describes it only as being “entrusted with the operation of the financial mechanism”.

This “somewhat murky” language is expected to face legal scrutiny in the weeks ahead of COP28.

Other issues

In an earlier draft text released at the fourth meeting, developing-country committee members disputed a line stating that the fund “does not involve liability or compensation”.

This has long been a fundamental issue for the US, in particular, because it does not want to be held legally accountable for its high historical emissions.

US committee member Chan told other members it was “absolutely unacceptable” that this was viewed as “a point of contention”:

“This was a key piece of the understanding that led to the agreement for this agenda item at Sharm el-Sheikh.”

She said that if this text was removed, “we don’t see a pathway to an outcome” on the fund overall. This language remained in the final recommendations.

Civil society groups also raised concerns about the removal of language committing to human-rights protections from the final recommendations. 

Back to top

How much money is needed to deal with loss and damage?

Developing-country transitional committee members made a submission in September calling for “at least” $100bn a year in loss-and-damage funding by 2030.

They cited a UN-commissioned report by the Independent High-Level Expert Group on Climate Finance, which says “recent events suggest [costs] could be as high as $150-300bn by 2030 to cope with immediate impacts and for subsequent reconstruction”.

The expert report also emphasises the uncertainty of these figures, adding that climate models “likely underestimate” loss-and-damage costs in developing countries.

Indeed, the expert group’s figures are towards the lower end of existing estimates. Their report cites other studies as placing the costs of “residual damages” from climate hazards far higher – as much as £290-580bn annually in developing countries by 2030.

With this in mind, developing country representatives emphasised that a £100bn goal “is not meant as a ceiling, but rather as a minimum commitment.”

By contrast, US and EU submissions did not back any specific targets.

A draft of the final outcome, released at the fourth meeting in October, included a section titled “scale”, with the developing countries’ proposal in square brackets, meaning it had not yet been agreed by all parties. 

However, US committee member Chan said that she would not accept such a figure in the document. “This is not part of our mandate, it’s not part of what is in the Sharm decision,” she said.

Ultimately, any reference to the scale of funding was scrubbed from the final recommendations.

Back to top

What options are being considered to raise money for loss and damage?

One of the transitional committee’s goals was to “take into account the landscape of institutions and solutions relevant to responding to loss and damage”.

As part of the deal that emerged from COP27, countries commissioned the UNFCCC secretariat to review existing loss-and-damage funding and identify “gaps existing within the landscape”.

The secretariat released a synthesis report summarising its findings in May 2023, which has fed into the decisions made by the committee.

It identifies a variety of existing sources that are relevant for tackling loss and damage, including adaptation funds and insurance facilities.

Meanwhile, scientists and civil society groups have proposed alternative sources for loss-and-damage funds, such as taxes or levies on fossil fuels and global shipping.

One paper suggests allocating hundreds of billions of dollars in “climate reparations” charges to fossil-fuel majors such as, for example, Saudi Aramco and ExxonMobil.

Earlier versions of the transitional committee’s recommendations reflected a variety of potential sources, again in square brackets. These included private entities, NGOs and “special drawing rights (SDRs), levies, voluntary carbon market or international pricing mechanisms”.

However, the question of funding sources is contentious as, broadly speaking, developing countries have tried to keep the emphasis on grant-based finance from developed countries.

Developed countries, meanwhile, say that “innovative” new sources must be explored to raise money on a sufficient scale.

Speaking at the fourth committee meeting for the G77 and China, Brazilian diplomat Bastos told fellow committee members that they had “repeatedly asked for deletion” of language around raising money for the fund from the voluntary carbon market and other pricing mechanisms.

The final recommendation text does not include much detail on types of funding, but mentions a “wide variety of sources”, as well as saying it will be open to public, private and “innovative” contributions. It also specifies that it should be open to receiving funds from philanthropic foundations.

It says the fund’s board will prepare a strategy to “mobilise new, additional, predictable and adequate financial resources from all sources of funding”.

Back to top

How could countries claim money from the loss-and-damage fund?

As with many aspects of the fund, the question of how countries could actually claim money after experiencing loss and damage is still far from being answered.

Traditionally, countries access UN climate funds by filing lengthy project proposals in a process that typically takes several years.

For the loss-and-damage fund, some countries are instead calling for a “trigger-based mechanism” to allow them to claim funds immediately in the wake of extreme weather events, explains Zoha Shawoo, a scientist working on loss and damage at the Stockholm Environment Institute (SEI). She tells Carbon Brief:

“Something like that could work if there is an immediate recovery and relief window. But we know that developed countries have been saying that that is largely covered by humanitarian aid, so maybe the fund should focus more on medium- and long-term recovery.”

There are also still question marks around what sort of losses and damages countries would be able to claim for.

Loss and damage can be caused by immediate climate impacts, such as more intense and frequent extreme weather events, as well as impacts that gradually worsen over time, such as sea level rise and the retreat of glaciers.

The study of how climate change is affecting the likelihood and severity of extreme weather events is known as “attribution” science.

Attribution is playing an increasingly important role in proving liability in climate court cases. For example, a recent landmark court case won by young climate activists in Montana relied heavily on attribution science.

This has prompted some to question whether attribution could play a role in helping countries to make claims from the loss-and-damage fund.

However, Shawoo notes it may not be preferable for developed or developing countries to use attribution science in deciding who should access loss-and-damage funding:

“First, developed countries may not be comfortable with being held liable for particular losses. But then I think it could potentially also be a burden on developing countries to have to prove that a certain event is due to climate change. So I don’t think either side would want that.”

There still could be a role for attribution science in helping to provide evidence for the claims of developing countries however, she adds:

“Rapid attribution studies could provide additional evidence that developing countries could use to back up their claims and access funding. Not a formal requirement, but just something to give them additional leverage.”

So far, there has been little cross-talk between attribution scientists and those involved in the UN process for operationalising the loss-and-damage fund, Dr Izidine Pinto, a scientist from the World Weather Attribution initiative, tells Carbon Brief:

“Right now we’re separate because no one knows how the loss-and-damage fund is going to work.”

He adds that attribution may only be able to play a limited role in determining how much money countries should be able to claim from the loss-and-damage fund:

“Attribution studies are just one side of the coin. Attribution is saying that the amount of rainfall or heat was made more likely by climate change. But vulnerability is the other side of the coin, because the same amount of rainfall can destroy a house in region A but not B. So it’s very tricky to just focus on attribution without looking at vulnerability and exposure.”

Interview: COP31 president says electrification is ‘surest way to protect citizens’

Published

on

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.

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.

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.

Eight facts about air conditioning amid an overheated global debate

Published

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 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.
