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.

Vishal Prasad is director of Pacific Islands Students Fighting Climate Change.
When the International Court of Justice (ICJ) delivered its advisory opinion on climate change last year, it marked a turning point not just for the Pacific, but for international climate law.
The court was unambiguous: states have legal obligations to protect the environment from greenhouse gas emissions, and they face accountability when they fail. For those of us who carried this campaign from a classroom in Vanuatu to Europe and New York, it was a moment of profound validation.

But we have always said that the advisory opinion was a tool, not an endpoint. The ICJ affirmed what many in the Pacific have been saying for some time. Now we have a legal blueprint, we must carry this momentum from the courtrooms to the negotiating rooms.
Potential to shape climate politics
The advisory opinion has already begun to reshape the climate landscape. At COP30 in Belém, we saw countries that had supported the campaign citing the opinion in their interventions, while those blocking progress were clearly concerned of its implications. Its potential to shape climate politics and policy is significant.
This year we have arrived at the mid-year climate negotiations in Bonn not only with the advisory opinion, but with a UN General Assembly resolution endorsing it. Despite a fierce campaign from the usual suspects, just eight countries, including the USA, Saudi Arabia, Russia and Iran voted against. That is a victory for multilateralism at a moment when multilateralism is under strain.
UN General Assembly backs “climate obligations” set by world’s top court
But we know that advisory opinions alone are not enough. Legal clarity will not automatically translate into reduced emissions, increased finance flows or stronger national climate plans. That translation requires political will in the negotiating rooms, both here in Bonn and all the way through Fiji and finally in Antalya this November.
What the Pacific needs from this negotiating year
The Pacific put significant political capital into the joint Australia-Pacific bid for COP31. It is fair to say that the compromise of Australia holding the role of president of negotiations while the COP is held and presided over by Türkiye is not what we imagined.
But we in the Pacific are used to looking for silver linings. Both Australia and Türkiye have acknowledged the important role the Pacific will have at COP31, through the appointment of Pacific champions and the hosting of a Pacific Pre-COP in Fiji with a leaders event in Tuvalu. These are genuine opportunities to bring the world to our shores and ensure that Pacific issues are front and centre going into the final negotiations.
But we are not naive. Envoy positions and meeting locations are just the architecture of goodwill. We need to see that goodwill converted into concrete negotiating outcomes and finance.
COP31 leaders unveil global targets, with spotlight on electrification
The Pacific helped put Australia’s climate minister Chris Bowen in this important position, so we expect to see Australia advocate not only for us, but to turn a mirror towards itself as one of the world’s biggest fossil fuel exporters.
At Bonn, and then in Antalya, we need ambition on mitigation that reflects the ICJ’s clarity on state obligations and the science. That means action on fossil fuels.
We need climate finance that is new, additional and accessible to the countries that need it most. In the Pacific we have already demonstrated what that looks like.
The Pacific Resilience Facility is the first climate finance facility designed, governed and managed by Pacific people, built specifically to reach the grassroots and community initiatives that larger funds routinely bypass. We need the international community to meet that ambition with contributions that reflect climate justice, starting with pledges to meet the $500-million capitalisation goal.
And we need the oceans – which are the lifeblood of the Pacific and a critical part of the global climate system – treated as a central element of the negotiations rather than a thematic aside.
Energy crisis driven by imported fossil fuels
The days of speaking about climate and fossil fuels purely as a moral issue are long gone. Pacific ministers recently adopted the Tassiriki Call for a Fossil Fuel Free Pacific, in the context of a deepening energy crisis that has triggered states of emergency in several Pacific nations. Our dependence on imported fossil fuels is both a climate and an economic vulnerability.
Conflict in the Middle East is pushing our region into an energy crisis. We are dependent on imported fossil fuels for 80% of our energy needs. My home country of Fiji could see an increased fuel bill of nearly three times our annual healthcare budget.
Comment: COP31 must persuade countries to make fossil fuel transition plans
We need the technical and financial support to transition to 100% renewable energy. Not only because it is what the world owes us for decades of carbon pollution that continue to render parts of our home uninhabitable, damaging ecosystems and culture. But because we must be part of that transition. Fossil fuels have proven to be the greatest source of damage to our climate, and with their volatility, to our sovereignty as well.
What next?
The demands have not changed. Greater action on mitigation, adaptation, finance, loss and damage: these remain the substance of what the Pacific requires from the international community. What has changed is the legal foundation beneath them.
The ICJ has affirmed that these are not requests. They are obligations. The task this year is to make the negotiations reflect that.

A 20-year record reveals an estuary tipping toward a saltier, more acidic state. These conditions threaten its hammerhead shark nursery and the aquifer that supplies Miami’s drinking water.
In the shadow of Miami’s skyline, in water churned daily by boats and jet skis, juvenile great hammerhead sharks—a critically endangered species—spend the first two years of their lives. A few miles from downtown, researchers recently pulled a 12-foot critically endangered sawfish from the same shallows. The species has been dying off in alarming numbers across South Florida’s waters since 2024, in an event scientists suspect was set in motion by record ocean heat.
The Railroad Commission of Texas shut down injection wells to control a leak in a church parking lot. But 1.5 million gallons of toxic wastewater still spilled to the surface.
GRANDFALLS, Texas—An old oil well sprang back to life under the parking lot of the First Baptist Church of Grandfalls in April.
