The overlapping crises of extreme heat and Covid-19 “severely stretched” an already overwhelmed healthcare system in the UK with “deadly consequences”, a new study finds.
The research, published in Nature Climate Change, estimates the number of heat- and cold-related deaths in England and Wales before and during the Covid-19 pandemic.
The study finds that pressure on the health system during heatwaves was as much as three times higher for the pandemic years than it was in the previous decade. The authors find a similar result during cold periods.
The number of heat-related deaths “shifted higher” in the Covid-19 years, the study says, suggesting that Covid “may have impacted temperature-related mortality during extreme weather events”.
The authors warn that “if health services are already operating at capacity because of one crisis, the additional health burden from another crisis can break the system entirely, endangering the lives of many people”.
One expert not involved in the study tells Carbon Brief that any future pandemic is likely to be a “syndemic”, where its impacts intertwine with those of a changing climate.
And as similar groups tend to be most vulnerable to both major disease outbreaks and extreme weather, anticipating and preparing for the co-occurrence of such events “would be lifesaving”, the study authors conclude.
Heat, cold and Covid
Extreme weather events and pandemics are among the most serious risks facing the UK, according to the UK National Risk Register. Since 2020, both have claimed thousands of lives in the UK.
Between the UK’s first documented Covid-19 case on 30 January 2020 and the end of 2022, around 190,000 people in England and Wales died of the virus, according to death certificates.
Over this two-year study period, the UK has also seen extreme hot and cold temperatures – from the coldest UK temperature in more than 20 years during February 2021 to the country’s first recorded instance of 40C heat in July 2022.
To assess the link between temperature and mortality, the authors produced “epidemiological models” that analyse exposure to different temperatures and human mortality in different regions of the UK.
Dr Eunice Lo is a research fellow in climate change and health at the University of Bristol and lead author on the study. She tells Carbon Brief that “heatstroke and heat exhaustion can occur quite rapidly” and that, in her models, “we expect the mortality outcome to be within three days of exposure to heat”. In contrast, it takes longer for cold snaps to cause mortality, she adds.
The plot below illustrates the example of London. The lowest point on the curve – indicated by a “relative risk” level of one – shows the optimum temperature, when people are at lowest risk of physiological harm from temperature extremes.
If the temperature rises above (red) or falls below (blue) the optimum temperature, the risk of temperature-related mortality increases. This is indicated by a relative risk level greater than one.

The authors developed a series of models for locations across England and Wales. The study estimates that, over the study period, almost 8,500 excess deaths were attributable to high temperatures and more than 125,000 deaths to cold.
The study points out that cold-related deaths are more common in the UK as “most days of the year are considered moderately cold”. As the planet continues to warm, heat-related deaths are expected to rise, while cold-related deaths will likely fall.
Lo tells Carbon Brief that factors including age and socioeconomic status also affect temperature-related mortality, but these were not included in the model.
Extreme temperatures
The chart below, from the study, shows a timeseries of daily deaths attributable to heat (red), cold (blue) and Covid-19 (purple) in England and Wales over the study period. The black line shows deaths in the UK from all causes. The right-hand section of the chart focuses on the July 2022 heatwave, when daily heat-related mortality peaked at 580 deaths – higher than at any time of over the previous decade.
Annual “all-cause mortality” in England and Wales was higher during the pandemic than it was in the preceding decade, as Covid-19 drove up mortality rates, the study finds.
The authors note that cold-related mortality “dominated” heat-related mortality in all months other than July, August and September – adding that spikes in cold-related mortality often coincided with spikes in deaths due to Covid.
There are a range of reasons for this. For example, low humidity in winter allows droplets containing the virus to spread further. And peoples’ immune systems are weaker in the winter due to a lack of vitamin D, making them more vulnerable to the virus.
The study also notes that, over the whole study period, “cumulative temperature-related deaths exceeded cumulative Covid-19 deaths by 8% in south-west England”. And while total temperature-related deaths did not exceed those from Covid in other regions, they did amount to 58% (East Midlands) to 75% (London) of Covid-19 deaths by the end of 2022.
The approach used in the study assumes that deaths caused by Covid-19 and temperature extremes are independent of each other. In other words, individuals are assumed to die either due to Covid or as a result of extreme temperature exposure, but not a combination of the two.
Nonetheless, the findings suggest that Covid “may have impacted temperature-related mortality during extreme weather events”, the study says. For example, “heat-related mortality shifted higher in the Covid-19 years”, compared to extreme events that were not affected by the disease, the authors note.
At the same time, “extreme heat may have exacerbated Covid-19 mortality”, the authors note, pointing out that on 19 July 2022 – the day that 40C heat was recorded – Covid caused 91 more deaths than the daily average over 10-25 July.
The results “highlight the complex interplay between extreme temperatures and the Covid-19 pandemic, as well as its implications on population health and health services capacity”, the study says.
Mapped
The study maps out Covid- and temperature-related deaths to see how they vary regionally.
The authors select 70 heatwave days and 70 cold days from the 30 January 2020 to 31 December 2022 study period. They then calculate regional mortality rates due to Covid, heat and cold during these days.
The maps below show the ratio of temperature-related deaths to Covid-driven deaths over the full study period (left), heatwave period (middle) and cold period (right). Numbers below zero, shown in grey, indicate that Covid-related deaths are higher than temperature-related deaths. Numbers above zero, shown in blue and purple, indicate that temperature-related deaths are higher.
During heatwaves, heat-related deaths far exceed deaths due to Covid-19 in almost all the regions studied. The study finds that the ratio of temperature to Covid-related deaths was highest in London at 2.7, where temperatures tend to be higher.
(This is likely due, in part, to the urban heat island effect – in which a combination of factors, such as buildings, reduced vegetation and high domestic energy use, cause urban areas to become hotter than more rural regions.)
This finding shows that “that even during the Covid-19 pandemic, heatwaves posed a serious threat to public health”, the study says.
Meanwhile, during cold snaps – when both cold-related mortality and deaths due to Covid spiked – Covid-related mortality was higher. The ratio ranges from 0.4 in east of England to 0.8 in south-west England.
The authors suggest that this is mainly due to “large surges in Covid-19 mortality following the first emergence of the coronavirus and the domination of the Alpha variant, both of which occurred in winter”.
The authors then performed the same heatwave and cold snap calculations for the decade preceding the pandemic, to provide a 2010-19 pre-Covid baseline.
The maps below show the ratio of average annual deaths per 100,000 people during the Covid study period to that during the preceding decade, during heatwaves (left) and cold snaps (right). Lighter green indicates that mortality rates in the Covid and pre-Covid periods were similar, while darker colours indicate that deaths during the Covid study period were higher.
The authors find that during pre-Covid heatwave days, heat-related deaths ranged from six to 14 people per 100,000. They add that during the Covid-19 study period, deaths due to heat and Covid-19 together range from 19 to 24 deaths per 100,000 people.
The authors assume that mortality broadly links to regional demand on health services. As such, they estimate that demand on regional health services was between 1.6 (London) and 3.2 (north-west England) times higher during the pandemic than in the previous decade.
By carrying out the same analysis, the authors find that during cold snaps, demand on health services was between 2.0 (south-west England) and 3.4 (east of England) times higher during Covid than in the previous decade.
The paper highlights “the deadly consequences of an already overwhelmed NHS severely stretched to function through the compound crises of extreme weather and Covid-19”, the authors say, adding:
“If health services are already operating at capacity because of one crisis, the additional health burden from another crisis can break the system entirely, endangering the lives of many people.”
Dr Kristina Dahl is senior climate scientist at the Union of Concerned Scientists. In 2020, she was a co-author on a comment paper in Nature Climate Change on the compound risks of climate change and the Covid pandemic.
Dahl tells Carbon Brief that the results of this study highlight the need for “amplified public messaging to increase awareness of temperature-related risks”, for “stronger policies and protections around extreme weather”, and to “more adequately prepare public health systems for the co-occurrence of hazards”.
Co-occurring hazards
Despite the study treating temperature- and Covid-related deaths as independent, Lo tells Carbon Brief that “there is certainly a two-way interaction” between the two.
She explains that “a lot of vulnerabilities to temperatures and Covid-10 are shared”, noting that elderly people and those with pre-existing conditions are vulnerable to both extreme temperatures and viruses. This means that one could exacerbate the other, she warns.
She adds that many measures taken to reduce the spread of Covid may have contributed to a rise in temperature-related death. For example, closing social spaces, such as swimming pools and air-conditioned buildings, meant that many people “didn’t have as much of an escape” from the high temperatures in their homes, she says.
Dr Colin Carlson is an assistant research professor at Georgetown University’s centre for global health, science and security and another co-author on the Nature Climate Change comment paper.
Carlson, who studies the relationship between global climate change, biodiversity loss and emerging infectious diseases, tells Carbon Brief that “for the last two decades, we’ve been operating in a very limited framework with how we think about climate change and infectious disease”.
He adds that “going forward, every pandemic will probably be a ‘syndemic’ with a few climate change-related components”.
Lo notes that while this study focuses on the relationship between Covid-19 and extreme temperatures, it speaks to a larger point about the link between climate-related extremes and other hazards, as co-occurring crises can threaten healthcare and other key systems.
Similarly, Dahl warns:
“As climate-related extremes become more frequent, the likelihood that they will intersect with other crises – whether related to public health, social or political unrest, or other environmental problems – will increase.”

Dual impact of extreme heat and Covid-19 had ‘deadly consequences’ for UK
Drought and heatwaves occurring together – known as “compound” events – have “surged” across the world since the early 2000s, a new study shows.
Compound drought and heat events (CDHEs) can have devastating effects, creating the ideal conditions for intense wildfires, such as Australia’s “Black Summer” of 2019-20 where bushfires burned 24m hectares and killed 33 people.
The research, published in Science Advances, finds that the increase in CDHEs is predominantly being driven by events that start with a heatwave.
The global area affected by such “heatwave-led” compound events has more than doubled between 1980-2001 and 2002-23, the study says.
The rapid increase in these events over the last 23 years cannot be explained solely by global warming, the authors note.
Since the late 1990s, feedbacks between the land and the atmosphere have become stronger, making heatwaves more likely to trigger drought conditions, they explain.
One of the study authors tells Carbon Brief that societies must pay greater attention to compound events, which can “cause severe impacts on ecosystems, agriculture and society”.
Compound events
CDHEs are extreme weather events where drought and heatwave conditions occur simultaneously – or shortly after each other – in the same region.
These events are often triggered by large-scale weather patterns, such as “blocking” highs, which can produce “prolonged” hot and dry conditions, according to the study.
Prof Sang-Wook Yeh is one of the study authors and a professor at the Ewha Womans University in South Korea. He tells Carbon Brief:
“When heatwaves and droughts occur together, the two hazards reinforce each other through land-atmosphere interactions. This amplifies surface heating and soil moisture deficits, making compound events more intense and damaging than single hazards.”
CDHEs can begin with either a heatwave or a drought.
The sequence of these extremes is important, the study says, as they have different drivers and impacts.
For example, in a CDHE where the heatwave was the precursor, increased direct sunshine causes more moisture loss from soils and plants, leading to a drought.
Conversely, in an event where the drought was the precursor, the lack of soil moisture means that less of the sun’s energy goes into evaporation and more goes into warming the Earth’s surface. This produces favourable conditions for heatwaves.
The study shows that the majority of CDHEs globally start out as a drought.
In recent years, there has been increasing focus on these events due to the devastating impact they have on agriculture, ecosystems and public health.
In Russia in the summer of 2010, a compound drought-heatwave event – and the associated wildfires – caused the death of nearly 55,000 people, the study notes.
The record-breaking Pacific north-west “heat dome” in 2021 triggered extreme drought conditions that caused “significant declines” in wheat yields, as well as in barley, canola and fruit production in British Columbia and Alberta, Canada, says the study.
Increasing events
To assess how CDHEs are changing, the researchers use daily reanalysis data to identify droughts and heatwaves events. (Reanalysis data combines past observations with climate models to create a historical climate record.) Then, using an algorithm, they analyse how these events overlap in both time and space.
The study covers the period from 1980 to 2023 and the world’s land surface, excluding polar regions where CDHEs are rare.
The research finds that the area of land affected by CDHEs has “increased substantially” since the early 2000s.
Heatwave-led events have been the main contributor to this increase, the study says, with their spatial extent rising 110% between 1980-2001 and 2002-23, compared to a 59% increase for drought-led events.
The map below shows the global distribution of CDHEs over 1980-2023. The charts show the percentage of the land surface affected by a heatwave-led CDHE (red) or a drought-led CDHE (yellow) in a given year (left) and relative increase in each CDHE type (right).
The study finds that CDHEs have occurred most frequently in northern South America, the southern US, eastern Europe, central Africa and south Asia.
Threshold passed
The authors explain that the increase in heatwave-led CDHEs is related to rising global temperatures, but that this does not tell the whole story.
In the earlier 22-year period of 1980-2001, the study finds that the spatial extent of heatwave-led CDHEs rises by 1.6% per 1C of global temperature rise. For the more-recent period of 2022-23, this increases “nearly eightfold” to 13.1%.
The change suggests that the rapid increase in the heatwave-led CDHEs occurred after the global average temperature “surpasse[d] a certain temperature threshold”, the paper says.
This threshold is an absolute global average temperature of 14.3C, the authors estimate (based on an 11-year average), which the world passed around the year 2000.
Investigating the recent surge in heatwave-leading CDHEs further, the researchers find a “regime shift” in land-atmosphere dynamics “toward a persistently intensified state after the late 1990s”.
In other words, the way that drier soils drive higher surface temperatures, and vice versa, is becoming stronger, resulting in more heatwave-led compound events.
Daily data
The research has some advantages over other previous studies, Yeh says. For instance, the new work uses daily estimations of CDHEs, compared to monthly data used in past research. This is “important for capturing the detailed occurrence” of these events, says Yeh.
He adds that another advantage of their study is that it distinguishes the sequence of droughts and heatwaves, which allows them to “better understand the differences” in the characteristics of CDHEs.
Dr Meryem Tanarhte is a climate scientist at the University Hassan II in Morocco, and Dr Ruth Cerezo Mota is a climatologist and a researcher at the National Autonomous University of Mexico. Both scientists, who were not involved in the study, agree that the daily estimations give a clearer picture of how CDHEs are changing.
Cerezo-Mota adds that another major contribution of the study is its global focus. She tells Carbon Brief that in some regions, such as Mexico and Africa, there is a lack of studies on CDHEs:
“Not because the events do not occur, but perhaps because [these regions] do not have all the data or the expertise to do so.”
However, she notes that the reanalysis data used by the study does have limitations with how it represents rainfall in some parts of the world.
Compound impacts
The study notes that if CDHEs continue to intensify – particularly events where heatwaves are the precursors – they could drive declining crop productivity, increased wildfire frequency and severe public health crises.
These impacts could be “much more rapid and severe as global warming continues”, Yeh tells Carbon Brief.
Tanarhte notes that these events can be forecasted up to 10 days ahead in many regions. Furthermore, she says, the strongest impacts can be prevented “through preparedness and adaptation”, including through “water management for agriculture, heatwave mitigation measures and wildfire mitigation”.
The study recommends reassessing current risk management strategies for these compound events. It also suggests incorporating the sequences of drought and heatwaves into compound event analysis frameworks “to enhance climate risk management”.
Cerezo-Mota says that it is clear that the world needs to be prepared for the increased occurrence of these events. She tells Carbon Brief:
“These [risk assessments and strategies] need to be carried out at the local level to understand the complexities of each region.”

DeBriefed 6 March 2026: Iran energy crisis | China climate plan | Bristol’s ‘pioneering’ wind turbine
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Energy crisis
ENERGY SPIKE: US-Israeli attacks on Iran and subsequent counterattacks across the Middle East have sent energy prices “soaring”, according to Reuters. The newswire reported that the region “accounts for just under a third of global oil production and almost a fifth of gas”. The Guardian noted that shipping traffic through the strait of Hormuz, which normally ferries 20% of the world’s oil, “all but ground to a halt”. The Financial Times reported that attacks by Iran on Middle East energy facilities – notably in Qatar – triggered the “biggest rise in gas prices since Russia’s full-scale invasion of Ukraine”.
‘RISK’ AND ‘BENEFITS’: Bloomberg reported on increases in diesel prices in Europe and the US, speculating that rising fuel costs could be “a risk for president Donald Trump”. US gas producers are “poised to benefit from the big disruption in global supply”, according to CNBC. Indian government sources told the Economic Times that Russia is prepared to “fulfil India’s energy demands”. China Daily quoted experts who said “China’s energy security remains fundamentally unshaken”, thanks to “emergency stockpiles and a wide array of import channels”.
‘ESSENTIAL’ RENEWABLES: Energy analysts said governments should cut their fossil-fuel reliance by investing in renewables, “rather than just seeking non-Gulf oil and gas suppliers”, reported Climate Home News. This message was echoed by UK business secretary Peter Kyle, who said “doubling down on renewables” was “essential” amid “regional instability”, according to the Daily Telegraph.
China’s climate plan
PEAK COAL?: China has set out its next “five-year plan” at the annual “two sessions” meeting of the National People’s Congress, including its climate strategy out to 2030, according to the Hong Kong-based South China Morning Post. The plan called for China to cut its carbon emissions per unit of gross domestic product (GDP) by 17% from 2026 to 2030, which “may allow for continued increase in emissions given the rate of GDP growth”, reported Reuters. The newswire added that the plan also had targets to reach peak coal in the next five years and replace 30m tonnes per year of coal with renewables.
ACTIVE YET PRUDENT: Bloomberg described the new plan as “cautious”, stating that it “frustrat[es] hopes for tighter policy that would drive the nation to peak carbon emissions well before president Xi Jinping’s 2030 deadline”. Carbon Brief has just published an in-depth analysis of the plan. China Daily reported that the strategy “highlights measures to promote the climate targets of peaking carbon dioxide emissions before 2030”, which China said it would work towards “actively yet prudently”.
Around the world
- EU RULES: The European Commission has proposed new “made in Europe” rules to support domestic low-carbon industries, “against fierce competition from China”, reported Agence France-Presse. Carbon Brief examined what it means for climate efforts.
- RECORD HEAT: The US National Oceanic and Atmospheric Administration has said there is a 50-60% chance that the El Niño weather pattern could return this year, amplifying the effect of global warming and potentially driving temperatures to “record highs”, according to Euronews.
- FLAGSHIP FUND: The African Development Bank’s “flagship clean energy fund” plans to more than double its financing to $2.5bn for African renewables over the next two years, reported the Associated Press.
- NO WITHDRAWAL: Vanuatu has defied US efforts to force the Pacific-island nation to drop a UN draft resolution calling on the world to implement a landmark International Court of Justice (ICJ) ruling on climate, according to the Guardian.
98
The number of nations that submitted their national reports on tackling nature loss to the UN on time – just half of the 196 countries that are part of the UN biodiversity treaty – according to analysis by Carbon Brief.

Captured
UK greenhouse gas emissions in 2025 fell to 54% below 1990 levels, the baseline year for its legally binding climate goals, according to new Carbon Brief analysis. Over the same period, data from the World Bank shows that the UK’s economy has expanded by 95%, meaning that emissions have been decoupling from growth.
Spotlight
Bristol’s ‘pioneering’ community wind turbine
Following the recent launch of the UK government’s local power plan, Carbon Brief visits one of the country’s community-energy success stories.
The Lawrence Weston housing estate is set apart from the main city of Bristol, wedged between the tree-lined grounds of a stately home and a sprawl of warehouses and waste incinerators. It is one of the most deprived areas in the city.
Yet, just across the M5 motorway stands a structure that has brought the spoils of the energy transition directly to this historically forgotten estate – a 4.2 megawatt (MW) wind turbine.
The turbine is owned by local charity Ambition Lawrence Weston and all the profits from its electricity sales – around £100,000 a year – go to the community. In the UK’s local power plan, it was singled out by energy secretary Ed Miliband as a “pioneering” project.
‘Sustainable income’
On a recent visit to the estate by Carbon Brief, Ambition Lawrence Weston’s development manager, Mark Pepper, rattled off the story behind the wind turbine.
In 2012, Pepper and his team were approached by the Bristol Energy Cooperative with a chance to get a slice of the income from a new solar farm. They jumped at the opportunity.
“Austerity measures were kicking in at the time,” Pepper told Carbon Brief. “We needed to generate an income. Our own, sustainable income.”
With the solar farm proving to be a success, the team started to explore other opportunities. This began a decade-long process that saw them navigate the Conservative government’s “ban” on onshore wind, raise £5.5m in funding and, ultimately, erect the turbine in 2023.
Today, the turbine generates electricity equivalent to Lawrence Weston’s 3,000 households and will save 87,600 tonnes of carbon dioxide (CO2) over its lifetime.
‘Climate by stealth’
Ambition Lawrence Weston’s hub is at the heart of the estate and the list of activities on offer is seemingly endless: birthday parties, kickboxing, a library, woodworking, help with employment and even a pop-up veterinary clinic. All supported, Pepper said, with the help of a steady income from community-owned energy.
The centre itself is kitted out with solar panels, heat pumps and electric-vehicle charging points, making it a living advertisement for the net-zero transition. Pepper noted that the organisation has also helped people with energy costs amid surging global gas prices.
Gesturing to the England flags dangling limply on lamp posts visible from the kitchen window, he said:
“There’s a bit of resentment around immigration and scarcity of materials and provision, so we’re trying to do our bit around community cohesion.”
This includes supper clubs and an interfaith grand iftar during the Muslim holy month of Ramadan.
Anti-immigration sentiment in the UK has often gone hand-in-hand with opposition to climate action. Right-wing politicians and media outlets promote the idea that net-zero policies will cost people a lot of money – and these ideas have cut through with the public.
Pepper told Carbon Brief he is sympathetic to people’s worries about costs and stressed that community energy is the perfect way to win people over:
“I think the only way you can change that is if, instead of being passive consumers…communities are like us and they’re generating an income to offset that.”
From the outset, Pepper stressed that “we weren’t that concerned about climate because we had other, bigger pressures”, adding:
“But, in time, we’ve delivered climate by stealth.”

Officials from about 20 countries met informally in Japan this week in a bid to bridge major differences in talks on a global treaty to curb plastic pollution, eight months after the last round of negotiations collapsed without agreement.
A participant told Climate Home News the closed-door meeting, hosted by Japan’s Environment Ministry, had been helpful to test ideas and restart conversations before formal talks resume, but said progress remained “challenging”, with national stances largely unchanged.
The meeting brought together countries pushing for efforts to rein in soaring plastic production, including European and Latin American nations, with major fossil fuel producers such as the United States, Saudi Arabia, Russia and Kuwait, which say the treaty should focus only on managing waste.
US hits out at EU and Pacific islands
In a sign of the persistent divisions, a spokesperson for the US State Department told Climate Home News after the meeting that Washington opposes “global plastic bans driven by the EU and Pacific Islands that would harm our economy and raise consumer prices”.
The EU and other members of the so-called High Ambition Coalition have called for the phase-out of certain plastic products that pose significant risks to human health and the environment, but have not advocated for any wide-ranging plastic ban.
“The EU is committed to securing a treaty with global measures across the full lifecycle of plastics, from production and consumption to waste management and end-of-life treatment,” a European Commission spokesperson told Climate Home News. “A global treaty can unlock economic opportunities, next to its environmental and health benefits,” the spokesperson added.

US set to exit UN climate convention in February 2027
With Trump’s announcement made official, the US will become the first country to leave the 1992 treaty
Dennis Clare, a negotiator for the Pacific island nation of Micronesia, told Climate Home News that the world produces too much plastic, driving the plastic and climate pollution that all countries are struggling so hard to reduce.
He said he hoped countries could agree on enough actions in the treaty to make some meaningful progress towards ending plastic pollution, but he added that there should be flexibility to adjust course along the way.
Rescuing talks from turmoil
Plastic production is set to triple by 2060 without intervention, according to the UN. As nearly all plastic is made from planet-heating oil, gas and coal, the sector’s trajectory will have a significant impact on global efforts to reduce greenhouse gas emissions.
The informal talks this week were seen as an attempt to facilitate discussions between some of the key nations before formal negotiations guided by the UN Environment Programme (UNEP) resume.
The process, which began in February 2022, was thrown into turmoil in the second half of last year. In August, nations left what was meant to be the last round of talks in Geneva with no agreement or a clear way forward after a chaotic night of negotiations. Two months later, the chair of the talks, Ecuadorean diplomat Luis Vayas Valdivieso, stepped down, citing personal and professional reasons.
Believing that countries can still deliver “a treaty for the ages”, the UNEP has been working to steer the process back on track. Veteran Chilean ambassador Julio Cordano was elected as the new chair during a one-day session in early February. In a letter to diplomats, Cordano acknowledged the task was “hard and complex”, but said establishing a global treaty was “not only achievable, but also urgently needed”.
Call for inclusivity
Andrés Del Castillo, a senior attorney at the Center for International Environmental Law (CIEL), said it was important to keep the process transparent and inclusive.
While Japan’s efforts to use its diplomatic leverage to address thorny issues are commendable, only a handful of countries – including “some of the biggest blockers” – attended the informal meeting, he said, while others championing stronger action were left out.
Explainer: Will AI data centres make or break the energy transition?
Following this week’s restricted gathering in Tokyo, all countries are set to exchange views on the way forward during an online meeting hosted by Cordano on March 12. It remains unclear when governments will reconvene for a formal negotiating session, but diplomats told Climate Home it is unlikely to take place in the first half of 2026.
A participant at the Tokyo meeting said countries must produce a significant shift in positions in the coming months to make reconvening formal negotiations worthwhile.
