Ten days of extreme heat killed 2,305 people in a sample of 12 European cities last month, with almost two-thirds of those deaths caused by climate change’s intensifying effect on heatwaves, new research estimated on Wednesday.
The early summer heatwave, which sparked wildfires and health warnings from Spain to Turkey, was between 2 and 4 degrees Celsius hotter than it would have been without climate change, according to the study by the Grantham Institute at Imperial College London and the London School of Hygiene and Tropical Medicine (LSHTM).
“These numbers represent real people who have lost their lives in the last days due to the extreme heat”, said Imperial College London climate scientist Friederike Otto.
“If we continue to follow the wishes of the fossil fuel industry and delay serious mitigation [emissions-cutting] further, more and more people will lose their lives for the financial benefit of only a tiny rich influential minority,” she told reporters during a conference call.
Separately, a report by the European Union’s Copernicus Climate Change Service said last month was the hottest June on record in Western Europe.
Otto highlighted the researchers’ rapid work in calculating the role of climate change in the overall death toll, which she hailed as a first.
Rapid attribution study
Previously, such research has taken months. A study into Europe’s 2022 heatwave, which found that climate change was responsible for just over half of the 68,000 deaths, was published a year later.
The new study has not been peer-reviewed, a sometimes lengthy process where other scientists evaluate the research, Otto said, adding that the methods it used to attribute deaths had undergone peer review and been approved.
She said publishing studies quickly is important because the immediate aftermath of a heatwave is “when people talk about it”. That is also why the researchers focused on a sample of just 12 cities, she said, making their analysis more manageable.
Previous studies from the World Weather Attribution group, which Otto co-leads, have only estimated how much hotter climate change has made a heatwave. Otto said she wanted to translate this into numbers of additional deaths because a temperature increase of a few degrees Celsius “might not sound very much”.
Otto said the reason the first study like this was carried out in Europe is because scientists have established the relationship between heat and deaths better in Europe than elsewhere. But there are parts of southern Africa, Asia and the USA where this relationship has been established by scientists, she said, so “we will probably do this again in other parts of the world”.
But LSHTM climate professor Malcolm Mistry, warned that carrying out this kind of study across the world would be “very challenging because not every public health authority wants to give out the mortality record reports for research purposes”. This data on deaths is key to establishing how many people are killed by a certain increase in temperature.
Silent killer
The study did not attribute any individual death to climate change and heat is generally not listed on death certificates. Most people who died had health problems exacerbated by the heat, and more than half of them were aged over 85.
Heatwaves are a “silent killer” because the deaths mostly take place in homes and hospitals, away from public view, and are rarely reported, said Pierre Masselot from the LSHTM.
But media reports have blamed last month’s soaring temperatures in some specific cases, such as the death of 48-year old builder who collapsed while laying concrete in 35C heat in the Italian city of Bologna, and a 53-year old woman with a heart condition who died in Palermo. Climate Home has spoken to relatives of people who died during extreme heat in Saudi Arabia and the Gaza Strip.
Otto said that too many media reports about heatwaves include photographs of children eating ice cream and happy people playing on the beach. “That’s a massive problem”, she said, although she added that more articles were now referring to the role of climate change in driving heatwaves.
The researchers behind the study said ways to cope with extreme heat included installing air conditioning, improving government heatwave warnings, planting more trees, building more parks, insulating buildings and painting roofs white.
“But at the end of the day,” said Masselot, “all these measures won’t probably be as efficient as just reducing climate change altogether [by] reducing our greenhouse gas emissions.”

Scientists hail rapid estimate of climate change’s role in heat deaths as a first
In the shadow of Ankara’s new international football stadium, a group of visiting journalists – including Climate Home News – perched on tiny chairs watched over by mannequins dressed in old mobile phones, newspapers and bottle tops.
As they sipped Turkish tea in a room meant to educate visitors – mostly schoolchildren – about recycling, they were addressed by Ekrem Yıldırım, lead on zero waste at Türkiye’s environment ministry.
After Yıldırım spoke of Türkiye’s plans to pursue “zero waste”, one journalist asked why the sugar cubes for the tea were individually wrapped in plastic and why water had been served in single-use plastic pots.
Yıldırım accepted that this kind of packaging is a problem and glass or porcelain is preferable. He added that legislation to ban single-use packaging has been introduced to parliament, but is not yet finalised.
The situation symbolised what Turkish experts and environmental campaigners flag as a contradiction between the “zero waste” image that the government – represented by First Lady Emine Erdoğan – presents to the world and the reality of rising Turkish waste generation, significant climate-wrecking methane emissions from landfills and a politically influential industry producing plastics from oil and gas.
International campaign lacks domestic punch
Türkiye’s Zero Waste initiative – which is a vague plan to reduce waste generation and increase recycling, rather than a specific goal to reach zero waste by any specific date – was launched in 2017.
It came at a time when the Turkish government was under fire for its coal mines, its refusal to ratify the Paris Agreement and its brutal response to protests against plans to turn Gezi Park in Istanbul into a barracks and shopping mall.
Ümit Şahin, climate lead at Sabancı University’s Istanbul Policy Center, said the Turkish government saw then, and still sees, the initiative as “a way to build its international reputation on environmental issues”.
“Recycling gives the government something visible to point to,” he said. “It can promote the campaign without taking on powerful fossil fuel interests or changing its development priorities in mining and energy.”
The campaign has been led by Emine Erdoğan, the wife of Türkiye’s long-time president, Recep Tayyip Erdoğan. In 2022, she convinced countries at the UN General Assembly to create an annual International Day of Zero Waste on March 30.
COP31 President Murat Kurum has picked up on the theme, saying that zero waste is “one of the main pillars” of Türkiye’s COP31 presidency. In September, he reminisced at a press briefing in the northern city of Trabzon about old-fashioned Turkish rural life where food waste would be given to animals, ripped clothes would be mended, and new attire was only for religious festivals.
President Erdoğan told leaders at September’s UN General Assembly in New York that an “incredible desire for consumption” was fuelling a “culture of waste”. “We cannot speak of justice in a world where tonnes of food are thrown into the garbage on one side while hundreds of millions of people collect food from garbage containers on the other,” he railed.
Sedat Gündoğdu, a marine biologist and environmental researcher at Türkiye’s Çukurova University, told Climate Home News that zero waste is a worthy concept. But when it comes to putting words into action at home, he said, the government has failed. Official statistics show the amount of waste each person in Türkiye generates has remained broadly unchanged since 2010 and the total annual amount has increased by 15%.
Single-use plastics ban
To help fix this, an European Union-style ban on single-use plastics – like plastic cutlery, cups and stirrers – was reported by state media in March to be working its way through parliament and expected to come into effect on September 1.
But PAGEV, a Turkish plastics industry trade association, argued that such “restrictive” policies had failed in the EU and would damage the Turkish economy and take away jobs.
Despite COP31 shining an international spotlight on the Turkish waste sector, the ban has yet to be approved by President Erdoğan. Gündoğdu and Greenpeace Türkiye campaigner Berk Butan fear that, if it is approved, it will be watered down so that Turkish companies can make single-use plastics in Türkiye even if they can no longer sell them in the country.
The latter restriction, Gündoğdu argued, would be “meaningless” because it cannot be enforced. Similar measures in Germany and Italy have failed, he said, because manufacturers just relabelled single-use products like plastic straws as multiple-use straws.
To close these loopholes, he said, strict definitions and design criteria are needed, which the Turkish legislation does not have. Butan added that single-use plastics could still be made in Türkiye, and then exported, used and dumped abroad, causing the same environmental damage somewhere else.
Türkiye’s other flagship waste prevention measure is a tax on plastic bags, which led to an immediate drop in usage when introduced in 2019. But, despite rampant inflation, the tax has risen from 0.25TL in 2019 to just 1TL ($0.02), meaning it’s several times less in real terms than in 2019.
“You can’t even buy chewing gum with one lira,” said Gündoğdu. “If you see one lira on the ground, you will not take it. So that’s why it’s meaningless.” Butan added that the government did not invest in creating behavioural changes among the public, such as encouraging them to shop with reusable textile tote bags. “They just put in the tax and they didn’t do the rest,” he said.
Landfills tidied up but still leaking methane
While the amount of waste generated keeps rising, there has been progress in dealing with the waste so that it is at least out of sight. Official statistics suggest more and more of it is being collected and, while the vast majority is still sent to landfill rather than recycled, those landfills are now covered and more advanced than they used to be.
On the outskirts of Ankara, waste management company ITC gave Climate Home News a presentation showing one such transformation. A before image shows what the nearby Mamak landfill looked like in 2006 – a huge open pile of garbage known in Türkiye as a “wild landfill”.
Another image shows what the site looks like now with the rubbish covered up with soil. ITC says that Ankara’s garbage is brought to them on trucks, and sorted into recyclables and biodegradable waste, which is then turned into compost or burned for energy. Waste heat is used to grow blueberries, tomatoes and lavender or to warm shoppers in a nearby branch of the Swedish furniture giant Ikea.
But despite this progress, satellite observations from Carbon Mapper shows the site is still leaking methane – a particularly potent greenhouse gas – into the atmosphere. Exactly how much is unclear from Carbon Mapper’s limited observations but the nearby Sincan landfill leaks about 1,200 kilogrammes of methane an hour into the atmosphere. Climate Home News analysis suggests this does similar damage to the climate as 73,000 petrol cars. ITC did not respond to a request for comment.
In October, a Guardian investigation showed these methane leaks were happening at landfills across Türkiye and are some of the worst in the world. Researchers from the University of California (UCLA) said they were “mind-boggingly large”. Aside from the climate damage, local residents near one Istanbul landfill report a smell so bad they told the Guardian they have to sleep with their windows closed even on hot summer nights.
Waste imports from Europe
Dealing with its own growing waste is difficult enough, but Türkiye also imports mountains of plastic from its European neighbours too. Ever since China restricted waste imports, the European Union has exported more plastic waste to Türkiye than to any other nation by far.
Despite European Commission concerns about how well Türkiye deals with the waste, the trade is expected to grow as an EU ban on exports to non-OECD countries – a category that does not include Türkiye – comes into force on November 21.
The export of waste to Türkiye has seen European countries accused of waste imperialism. Butan and Gündoğdu said Türkiye should ban waste imports. But COP31 President and Turkish environment minister Kurum pushed back on this during a press conference in Trabzon in September.
“You called it waste imperialism,” he said through a translator, but “nobody is forcing anyone” to import waste. He added that handling the waste creates jobs in Türkiye and that it doesn’t matter to the environment where the waste is recycled as long as it is.
But most of Türkiye’s municipal waste is currently not recycled. Turkish official Yıldırım said that the country’s recovery rate is currently around 30%. The most recent statistics available from the EU suggest Türkiye in 2020 had a recycling rate of 12%. The EU country average in 2024 was about 50%.
At the zero waste centre in Ankara, Yıldırım said Türkiye is improving its recycling rate and wants to do even more. The aim, he said, is to reach a rate of 70% by an unspecified date, up there with global frontrunners like Germany.
To achieve that, he said Türkiye is raising awareness of the importance of recycling including through cartoons for children and initiatives for football supporters to collect and redistribute unwanted toys.
As he spoke to journalists, a portrait of the ‘Girl with a Pearl Earring’ made from buttons, a sultan made from old plastic straws and a horse and wolf made from metal cogs and screws looked on. “The world is something that has been entrusted to us, and waste is something you steal from the future,” said Yıldırım.

More than 92,000 people have registered to attend the COP31 climate summit in Antalya, Turkey, potentially making it the largest COP in history.
Carbon Brief analysis of the provisional lists of delegates, published by the United Nations Framework Convention on Climate Change (UNFCCC), reveals that more than 14,000 delegates have been registered as “host country guests”.
For comparison, the provisional list for COP30 in Belém, Brazil, last year included only around 1,000 delegates in this category.
As with COP30, Donald Trump’s US government has not sent a delegation. Other no-shows include Israel and Myanmar.
It was reported ahead of the summit that Taliban officials from Afghanistan had been registered for the event as observers; however, there are no delegates from observer states in the provisional lists.
With more than 3,000 “virtual” delegates signed up to attend the summit online, the total number of people registered for the event surpasses 95,000.
Further analysis of the participant lists will be added to this article in due course.
Party delegates
With 92,934 participants registered, COP31 is provisionally the largest COP in history – topping COP28 in Dubai, which was attended by more than 80,000 people.
This total is based on the delegates that have registered to be at the summit in person. The UNFCCC releases the final figures – based on participants collecting a physical badge at the venue – after the summit has ended.
The chart below shows how the provisional figures for COP31 compare to the final totals in previous COPs – going back to COP1 in Berlin in 1995.
The participant lists provided by the UNFCCC are divided between the different types of groups and organisations attending the summit. The largest group at COP31 is for delegates representing parties. These are nation-states, plus the European Union, that have ratified the convention and play a full part in negotiations.
This group adds up to 18,812 delegates – the second largest after COP28.

(In keeping with recent COPs, the UNFCCC has published spreadsheets that name every single person that has registered for the summit – excluding support staff. Previously, COPs have typically included thousands of “overflow” participants in which countries and UN agencies could nominate delegates without their names appearing on their official lists.)
For consistency with Carbon Brief’s analysis of previous COPs, the above chart includes overflow delegates as a single group. However, the participant lists do divide the overflow delegates between parties and observer groups. Including the overflow numbers takes the total for party representatives to more than 34,000.
Nations
The map and table below present the delegation size – split between party and overflow badges – for all the countries registered for COP31. The darker the shading, the more delegates that country has signed up. Use the search box to find the data for a specific party.
Unsurprisingly, host nation Turkey has registered the largest delegation for COP31 – with 2,950 people.
Following behind are Brazil (1,994 people), Nigeria (1,506), China (1,021) and Indonesia (978).
The rest of the top 10 is made up of Australia (835), Uganda (627), Italy (607), Japan (588) and Kazakhstan (557).
The UK comes someway down the list with a delegation of 255.
