Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
US-China meet
ENERGY TALKS: Trump administration officials have raised the prospect of China buying more US oil in response to the disruption caused by the Iran war, following two days of talks between the leaders of the superpowers in Beijing, said Reuters. On Thursday, US treasury secretary Scott Bessent told CNBC the nations had discussed China “buying more US energy”, adding that production from Alaska would be a “natural” for China. The Hong Kong-based South China Morning Post reported that Trump and Xi also agreed that the strait of Hormuz must remain open to “support the free flow of energy”.
CLIMATE ‘COOPERATION’: Ahead of the talks, the Communist party-affiliated People’s Daily published an article saying that addressing climate change requires “coordinated efforts and cooperation” between China and the US. State-run newspaper China Daily said that US-China cooperation on energy security and climate governance is “essential” because the two countries have “considerable influence over international institutions”. However, an article in Legal Planet said that the Trump-Xi meeting had no climate agenda, adding that the two countries are now moving in “radically different directions”.
El Niño extremes
‘SUPERCHARGED’: From wildfires to heatwaves and flooding, scientists have warned that the El Niño weather pattern could “amplify climate extremes” in 2026, reported Climate Home News. There is an 82% chance of a “very strong” El Niño forming this year, according to the average of four weather forecasters cited by the Times. The Independent added that the phenomenon could be “supercharged” by another weather pattern – a positive Indian Ocean Dipole – raising the risks of fire, drought risks and other extreme weather events.
WORLD ON FIRE: Global fire outbreaks hit a “record high” in Africa, Asia and elsewhere this year, reported Reuters, with conditions expected to worsen to the “highest in recent history” if a strong El Niño “kicks in”. More than 150m hectares of land were damaged by fires from January to April – 20% more than the previous record – according to data compiled by the World Weather Attribution (WWA) research group cited by the newswire.
Around the world
- ETHIOPIA EVS: Electric vehicles now account for 8% of Ethiopia’s car fleet as “soaring prices and fuel shortages compel” African countries to switch to “cleaner and cheaper transport”, according to the Associated Press.
- UK AID CUT: The UK has halved its most recent contribution to the UN’s Green Climate Fund (GCF) as part of a government “shift from development aid to military spending”, according to Climate Home News. The UK is no longer the top donor to the GCF following the move, said Carbon Brief.
- TORT RETORT: Reuters reported that the New Zealand government plans to amend a key climate law, to prevent courts from holding private companies liable for climate harms. This would apply to “both current and future proceedings”, the newswire said, including a current case against six major emitters.
- RENEWABLE SECURITY: Military alliance NATO is “openly backing renewables and other non-fossil fuel sources of energy as key to the alliance’s security” despite US scepticism, reported Politico. The outlet covered a NATO-backed study that highlighted how imported fuels have been used as a “bargaining chip” in conflicts.
- NO INDIAN ‘LOCKDOWN’: India’s oil-and-gas minister “dismissed concerns of any imminent lockdown-like restrictions” after prime minister Narendra Modi “urged citizens” to adopt fuel-saving measures amid a global energy crisis, reported the Economic Times.
One billion barrels
The volume of oil the world has lost over the past two months since Iran began its blockade of the strait of Hormuz following attacks by the US and Israel, according to Saudi Aramco CEO Amin Nasser, quoted in Reuters.

Captured

Contrary to claims by the UK car industry that demand is not high enough to meet the UK government’s sales targets for “zero emissions vehicles” (ZEVs), a new Carbon Brief factcheck found it has actually “overcomplied” with its mandate. The chart above shows the required (left) and achieved (right) share of ZEVs in total UK car sales in 2024, the latest figures available. “Flexibilities” (in light blue) include the sale of lower-emission petrol cars.

Chennai’s gig workers race against the heat
This week, Carbon Brief visits one of India’s first air-conditioned lounges designed to help gig workers deal with extreme heat.

On a single day in late April, 20 of the world’s hottest cities were all in India.
Chennai was not on the list this time, but is no stranger to high temperatures. In the south-eastern coastal capital of Tamil Nadu, extreme humidity and heat are inescapable facts of life.
“The heat is by no means manageable, but we have no choice but to deal with it,” said Mohammed S, a 29-year-old grocery platform delivery worker, speaking to Carbon Brief.
Last year, Chennai became India’s first ever city to roll out air-conditioned lounges for millions of gig workers, like Mohammed, navigating India’s increasingly hotter cities.
Lounge access
In the dense shopping district of T Nagar – recognised as an “urban heat island” – studded with silk sari and jewellery shops, an unassuming oblong container-like structure stands out.

Through the building’s tinted windows, workers wearing synthetic jerseys emblazoned with food delivery app logos are stretched out on wooden benches meant to seat 25 people.
The lounge has charging points for phones, a water cooler and a unisex toilet. It might not seem like much, but workers tell Carbon Brief that it has made a “huge difference” to their lives – even on a day when the air conditioner stopped working.
“Before this, life was very difficult,” said Mohammed. He continued:
“We would park our [electric] bikes and try to find a tree to sleep under, stop for tea and tea shop owners would tell us we couldn’t sit there for more than 10 minutes, try to rest in a building’s stairwell and be chased away, then try to find shade under a flyover. Now we can sit in the AC and avoid the worst of the heat.”
Dinesh, 27, said his day starts at dawn before the sun is up, picking up packages from companies in north Chennai – another critical heat hotspot.
For the next seven hours, there is no “off point” or breaks for Dinesh as apps rush deliveries.
Some of Chennai’s gig workers told Carbon Brief they try to avoid the worst of afternoon temperatures from noon to 3pm, but for many – especially migrant workers – sitting back in the lounge is not a choice they can afford. One of them explained:
“If you don’t have cash to cover your bills or have to send money back home, you head out into the heat for a 12-hour shift and hope for the best.”

Feeling ‘gear’
In Chennai, heat might be normalised, but it has its own vocabulary. Speaking to Carbon Brief, the city’s gig workers, auto rickshaw drivers and fish sellers used an all-encompassing term – “gear” – to describe their symptoms, including dizziness, exhaustion and nausea.
Last summer, researchers offered Delhi’s gig workers a Rs 200 (roughly £2) cash transfer on the first day of a heatwave, to provide them with a means to achieve “real-time” adaptation to heat risk. Workers who received a cash transfer reported fewer heat-related symptoms, according to the study.
Asked if they would accept similar incentives to stay home on 40C days, workers in the T Nagar lounge expressed disbelief. Dinesh – who also trains technicians on how to repair air conditioners to support his income – told Carbon Brief:
“They [the apps] offer us incentives to go out in the heat when there are fewer riders.”
Barring a few, none of the dozens of outdoor workers Carbon Brief spoke to had an air conditioner at home or in their hostels, making the lounge the only place they could cool down.
Watch, read, listen
THE BIG ‘LOSER’: Writing in Foreign Affairs, Princeton University’s Prof Benjamin Bardlow argued that Beijing “may emerge from the war in Iran as its winner – and Washington its ultimate loser”.
CARBON ‘KINGPIN’: A new podcast by Drilled followed Bruce Rastetter – a corn ethanol “kingpin-turned-carbon entrepreneur” from Iowa – now promoting biofuels and carbon-capture projects in Brazil.
OPEC ‘DRAMA KINGS’: An episode of the Polycrisis podcast, titled “Gulf drama kings”, dug into the UAE’s announcement that it was quitting oil producers’ cartel OPEC, asking whether this reflected “doom” for the group, geopolitical tensions, or “different beliefs” about the future of oil.

Campaigners oppose Dangote’s planned Kenya refinery over climate and ecological risks
Climate and environment campaigners have urged the Kenyan government to halt plans for a proposed 700,000-barrel-per-day oil refinery backed by Africa’s richest man, Aliko Dangote, warning the project threatens one of East Africa’s most ecologically sensitive coastlines.
The refinery, which is planned to be situated in Lamu County on Kenya’s northern coast, will be East Africa’s largest refining project and is expected to take up to three years to build. Once finished, it would supply refined petroleum products to Kenya, Uganda, Tanzania and Rwanda, among others, helping to reduce the region’s dependence on imported fuels.
Campaigners are questioning the viability of such a large refinery at a time when renewable energy and electric transportation are expanding rapidly.
Mohamed Adow, director of a Kenya-based climate and energy think-tank Power Shift Africa, said the decision to give Dangote the green light for the refinery is “an extraordinary act of environmental recklessness and economic short-sightedness”, arguing it would tie Kenya to “yesterday’s energy system” just as global demand for petroleum products faces increasing uncertainty.
Campaigners argue the refinery risks coming online just as transport – the largest market for petrol and diesel – is beginning to electrify across the continent.
Kenya launched a National Electric Mobility Policy earlier this year to speed up the uptake of electric vehicles (EVs) and reduce the country’s roughly $5 billion annual fuel import bill. Ethiopia has already banned imports of non-electric vehicles and now has more than 100,000 EVs on its roads, while Rwanda is expanding its electric mobility programme with plans to convert its fleet of around 100,000 motorcycles to electric.
Adow said the project risks billions of dollars in investment in infrastructure that could become obsolete as the world moves away from oil.
“Building a refinery today assumes decades of robust demand for fuels that much of the world is actively trying to phase out,” he said in a statement.
Ecological concerns
Lamu – the proposed site for the project – is home to the UNESCO World Heritage-listed Lamu Old Town and an archipelago containing extensive mangrove forests, coral reefs and seagrass beds that support fisheries, tourism and coastal livelihoods.
Locating the refinery in Lamu would “place one of Africa’s largest fossil fuel developments in one of the continent’s most ecologically sensitive and culturally significant coastal regions,” Power Shift Africa said.
Major emitting countries knew of climate risks decades earlier than claimed
Sherelee Odayar, oil and gas campaigner at Greenpeace Africa, warned that a refinery of this scale could increase the risk of habitat destruction, marine pollution, oil spills and air pollution in one of East Africa’s most fragile coastal ecosystems.
She said the risks stem not only from the refinery itself – including storage tanks, pipelines and fuel handling facilities – but also from the large volumes of crude oil that would need to be shipped into Lamu and refined products exported by sea. Increased tanker traffic and fuel transfers, she said, would raise the likelihood of accidents in ecologically sensitive coastal waters.
Odayar added that Lamu’s low-lying, flood-prone coastline could compound those risks by damaging infrastructure and carrying contaminants from storage facilities into nearby fishing grounds and marine ecosystems.
“Lamu’s mangroves, coral reefs and seagrass beds are not expendable; they support fisheries, livelihoods and coastal protection,” Odayar added.
She said Kenyan authorities should suspend any approvals until an independent environmental and social impact assessment is completed, with genuine public participation and transparent scrutiny of the long-term economic, health and ecological risks.
“Any review must assess cumulative impacts on Lamu’s mangroves, coral reefs, seagrass beds and fishing livelihoods, alongside the wider economic risk of locking Kenya into costly fossil fuel infrastructure as the global energy transition accelerates”.
Dangote Group declined to answer questions from Climate Home News when contacted by phone.
Technological change threaten project’s future
The Kenya refinery would replicate Dangote’s 650,000-barrel-per-day refinery in Lagos, currently Africa’s largest, which has plans to more than double capacity to 1.4 million barrels per day by 2028.
Adow of Power Shift Africa said projects like this represent “a breathtaking failure to recognise where the global economy is heading”, pointing out that the East African refinery risks arriving when Africa is experiencing an unprecedented clean energy boom.
Referencing Africa’s solar boom, global electric vehicles uptake and the International Energy Agency’s projection that global oil demand is set to enter a decline later this decade, the think-tank founder said African governments risk anchoring the continent’s future to an industry facing mounting economic uncertainty.
Loss and damage fund delays first project approvals as needs dwarf resources
The organisation said the project faces a bigger threat aside from environmental opposition and that is technological change. “The danger is not simply that the refinery will pollute, it is that it will become obsolete long before it has paid for itself,” he added.
Kenyan President William Ruto said the project will create about 60,000 jobs for Kenyans and supply refined fuel to eight East and Central African countries.
GreenPeace Africa’s Odayar said the promise of ‘thousands of jobs’ cannot be used to hide the true cost of the investment which is that large fossil fuel projects often create temporary jobs while undermining existing livelihoods in fishing, tourism and small-scale local economies.
“The enormous capital required for a project of this scale could instead help accelerate Kenya’s renewable energy future through solar, wind, geothermal, storage and better energy access,” she added.

Major emitting countries knew of climate risks decades earlier than claimed
Lindsay Fenlock is a senior researcher in the Climate and Energy Program at the Center for International Environmental Law (CIEL). Nikki Reisch is a human rights lawyer and social justice advocate who leads the Climate & Energy Program at CIEL.
Much has been written about when fossil fuel companies knew their products cause harm to the climate, public health, and the environment. Less attention has been paid to just how long governments have known, too, and what they did or failed to do with that knowledge. That information is not just a matter of historical record – it’s a matter of legal responsibility.
A year ago this month, the world’s highest court affirmed that countries have been under an obligation to curb climate change since they knew about the foreseeable risks it posed and to remedy its harms. This historic advisory opinion opened the door for States to be held accountable not only for failing to act on climate change, but also for making it worse by perpetuating its primary cause: fossil fuel production and use.
While the ruling is clear about the content of climate duties under international law, it is silent on when those duties first applied to specific countries or how long they have been breaching them. The earlier governments knew about the drivers and dangers of climate change, the longer they have been under an obligation to prevent it, and the greater their potential liability for the resulting harms.
Once they were informed of the risks fossil fuels posed to the climate, States had a duty to do everything in their power to prevent those risks from materializing – and at a minimum, to refrain from exacerbating them. But, as trends in fossil fuel dependence and climate destruction make clear, they did not.
Early knowledge
A new report from the Center for International Environmental Law shows that the governments of many major emitting countries have known since at least the 1960s that fossil fuel use was warming the planet and, if continued, could lead to dire impacts – including melting of the polar ice caps, catastrophic sea level rise, and extreme heat.
Yet some of the countries responsible for the largest cumulative shares of carbon emissions have claimed that global awareness of climate change emerged only in the late 1980s, around the time the Intergovernmental Panel on Climate Change (IPCC) was established and negotiations of a climate convention began.
Loss and damage fund delays first project approvals as needs dwarf resources
Why? Because admitting that they have known about the chief causes and foreseeable consequences of climate change for the better part of a century would mean they had a duty to prevent it that they’ve been flouting for decades.
Drawing on a wide range of publicly available government records and scientific studies, CIEL’s research exposes when knowledge of climate change made its way onto policymakers’ desks and into public discourse. The report synthesizes some of the groundbreaking research by scholars such as Naomi Oreskes on the history of American climate science, putting their findings into a legal context and broadening the discussion to other countries.
First findings in 19th century
The origins of the climate harms the world is experiencing today – more extreme storms, deadly heat waves, floods, and sea level rise – stem from around 1850, when industry began burning so much fossil fuel that the concentration of carbon dioxide in the atmosphere began to rise.
Scientists figured out quite quickly that the release of these ancient carbon stores could warm Earth. The first paper that modeled the potential warming impact of fossil fuel use, for example, came out in 1896, while the first studies that confirmed global temperatures were rising came out before World War II.
Government records show international cooperation on climate change research picking up around 1957, when countries worldwide coordinated funding for thousands of research projects as part of the International Geophysical Year (IGY).
The IGY spawned the world’s first program to monitor atmospheric carbon dioxide levels, and the 69 participating governments were apprised of the results. By this time, governmental scientific organizations in most of the world knew that continued fossil fuel use could heat the planet dramatically, with potentially significant adverse impacts. Many countries also became aware of industry research on climate change during this decade through their state-owned oil companies.
Big emitters knew
In the 1960s, the world’s top atmospheric scientists, chemists, and geophysicists concluded that fossil fuel emissions not only could warm the earth, but they were already doing so. They also concluded that continuing to release carbon dioxide into the atmosphere was likely to cause serious harm to food systems, ecosystems, human health, and communities, including through sea level rise and deadly extreme weather events. By the 1960s and 1970s, many governments had ample warning that continued reliance on fossil fuels could have profoundly dangerous global consequences.
Evidence indicates that this information reached public officials — in some cases at the highest echelons of government. In the United States – the largest historic emitter of carbon dioxide – White House officials exchanged memos over what to do about the “carbon dioxide problem” during the 1960s and a presidential report published in 1965 unequivocally attributed warming to fossil fuels and warned about catastrophic levels of temperature and sea level rise if trends continued.


In the United Kingdom, the greenhouse effect was first raised in a parliamentary debate in 1969, and in France, a state-owned oil company published a magazine article about the dangers of atmospheric carbon dioxide in 1971, while the Canadian environment ministry regularly published articles about climate change in its employee magazine throughout the 1970s and 80s.
Even the most generous reading of this information shows that many of the world’s largest contributors to climate change, including the United States, Canada, Germany, and Australia, knew enough to change course over two decades before the first meeting of the IPCC in 1988, if not far earlier.
The story does not end there. As an illustrative compilation of publicly available, English-language evidence, CIEL’s report is not a complete survey of what all major emitters knew. And facts about what a given country knew are not, on their own, sufficient to secure accountability. But, together with evidence about how that knowledge was subsequently acted upon – or, as was often the case, denied, dismissed, and distorted – and about how climate impacts have unfolded, they solidify foundations for climate justice and repair.

Albanese rolls out the red carpet to data centre ‘energy vampires’, delays meaningful legislation
SYDNEY, Wednesday 15 July 2026 — Greenpeace Australia Pacific has called for an urgent pause on data centre approvals, after Anthony Albanese revealed the government’s AI legislation won’t be introduced until 2027.
The PM outlined plans for “greater clarity and speed for approvals” for data centre proponents, but, despite acknowledging the severe strain these facilities place on Australia’s land, water, and clean energy resources, will not bring legislation to Parliament until early next year.
Last month, Greenpeace called on the Federal Government to urgently implement a moratorium on the construction and approval of new data centres until appropriate regulations and safeguards are in place to protect the climate and communities.
Joe Rafalowicz, Head of Climate and Energy at Greenpeace Australia Pacific, said:
“The PM’s speech today shows that this government is kicking the can down the road, while Australians right around the country are calling for urgent regulations on AI data centres that are already being built in their backyard. We shouldn’t be talking about ‘faster decision making’ when there are no laws in place to protect our communities from this dangerous industry.
“We urgently need a moratorium on AI data centre approvals until there are binding rules in place to protect our communities, our climate and our environment. The Prime Minister is rolling out the red carpet for these water-guzzling energy vampires, with no plans to regulate them until at least 2027 — that is a betrayal of Australian communities and our national interest.
“Big tech companies are looking to make Australia their second home, but in the US, AI data centres are wreaking havoc on people’s health, drinking water and air by running their data centres on gas. They’ve set their own house on fire, and we shouldn’t be opening the door to let them do that here.
“No new data centres should be approved until there are clearly defined, enforceable regulations in place, including requiring 100% additional renewable energy, that protect people, our climate and our environment – and absolutely no new fossil fuels like gas.”
