Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
UK election
SURPRISE: UK prime minister Rishi Sunak announced in a “surprise move” that a general election will be held on 4 July, Business Green reported. It quoted him saying that “this election will take place at a time when the world is more dangerous than it has been since the end of the Cold War”, highlighting “national and energy security” as key issues.
HEAVY DOWNPOUR: On the same day that Sunak made the announcement amid a downpour outside Number 10, a World Weather Attribution study covered by the Press Association found rainfall during storms across the UK and Ireland between October 2023 and March 2024 was made 20% more intense by global warming. The UK’s winters will continue to get wetter in future, according to the study, until the “world reduces emissions to net-zero”.
Oceans court ruling
MARINE PROTECTION: The International Tribunal for the Law of the Sea, the world’s highest court dealing with the oceans, issued a “groundbreaking opinion” on Tuesday ruling that greenhouse gases are a pollutant that could cause “irreversible harm to the marine environment”, the New York Times said. It added that, while “not binding”, the opinion stated that, legally, nations must “take all necessary measures” to cut back emissions to prevent marine pollution.
‘HISTORIC’ VICTORY: Climate Change News reported that the coalition of small island nations responsible for the case called the ruling a “historic” victory. It quoted Gaston Browne, prime minister of Antigua and Barbuda, saying the decision “will inform our future legal and diplomatic work in putting an end to the inaction that has brought us to the brink of an irreversible disaster”.
CLIMATE ‘VICTIMS’: Elsewhere, the Financial Times reported that a first-of-its-kind criminal case has been filed against the fossil-fuel company TotalEnergies and its shareholders by people who have lost family members or suffered harm in weather events made more extreme by climate change. The victims, along with non-profit groups, are accusing the company of criminal wrongdoing, including involuntary manslaughter, the FT said, adding that the company had not responded to its request for comment.
Around the world
- ANTARCTIC RECORD: The Press Association covered a study by the British Antarctic Survey finding record low sea ice levels around Antarctica last year “may have been influenced by climate change”.
- INDIA HEATWAVE: The Indian capital New Delhi felt like a “furnace” and recorded temperatures “soaring” above 46C on Monday, with high temperatures continuing throughout a crucial week in the country’s elections, the Hindustan Times reported.
- AUSTRALIAN COAL DEPENDENCE: Utility company Origin Energy will “delay the closure of Australia’s largest coal-fired power station”, Bloomberg reported, due to government concerns that there is not enough renewable energy to replace it.
- GERMAN BACKSLIDING: Germany approved a “controversial” reform of its climate protection law, eliminating sectoral targets and reducing pressure on sectors such as transportation and buildings to meet them, according to Die Zeit.
- EASTER ISLAND HERITAGE: The Guardian reported that the faces of Easter Island moai statues are being eroded due to “torrential rain”, quoting one conservator saying “we have much more extreme weather than before”.
- US OVERCAPACITY CALLS: US treasury secretary Janet Yellen urged the EU and G7 countries to “communicate to China as a group” regarding concerns about clean-energy industry overcapacity, Reuters said.
52%
The percentage of children in Pakistan who will not be in school next week, as heatwaves force closures in the country’s most populous province, according to the Associated Press.
Latest climate research
- A new study in Nature Communications underscored the importance of considering reliability and carbon pricing for the potential role of off-grid solar power in achieving universal household electricity access in Africa.
- Video gamers are “a worthwhile potential audience” for climate communications, according to a new Climatic Change study, in contrast to “the stereotype of video gamers as disengaged or antisocial” on the topic.
- New research in Proceedings of the National Academy of Sciences found that while “most of the Amazon does not show critical slowing down” of recovery from small disturbances, a “predicted increase in droughts could disrupt this balance”.

Captured

A new Carbon Brief Q&A explored the continuing debate around the role of genetically modified organisms (GMOs) in a world dealing with climate change. Some argue that new gene-editing technologies could help crops deal with extreme weather and boost nutrition, while others cite concerns around production, regulation and patenting of gene-edited crops. Much of current GMO production is concentrated in a small number of countries. The figure above shows that 91% of the land growing genetically modified crops is in the US, Brazil, Argentina, Canada and India. By contrast, genetically modified crops are not currently widely grown in the EU.
Spotlight
The future of China and Russia’s energy cooperation
This week, Carbon Brief examines energy’s role in Sino-Russian relations and how this could change as China moves towards its goal of carbon neutrality by 2060.
Vladimir Putin chose to visit China on 16-17 May, shortly after beginning another term as Russian president.
Previously “sizeable” Sino-Russian energy cooperation has only grown since Russia’s war with Ukraine.
Russia leapfrogged Saudi Arabia in 2023 to become China’s largest supplier of oil. China is now Russia’s top purchaser of coal and crude oil, as well as a top three purchaser of oil products, liquefied “natural” gas (LNG) and pipeline gas.
‘Concrete plans to enhance cooperation’
The two sides published a joint statement during Putin’s visit, pledging to “consolidate Sino-Russian strategic energy cooperation…to safeguard [our] economic and energy security”.
It named oil, gas, LNG, coal and electricity as primary areas for cooperation, with renewables, hydrogen and the carbon market as “prospective” areas.
Progress on the Power to Siberia 2 gas pipeline negotiations, which could supply China with 50bn cubic metres of gas, was not mentioned.
Economic and geopolitical drivers
“Economic complementarities” have led to “robust” Russian imports of oil and gas to China.
Chinese reliance on substantial oil imports will likely “persist”, although future gas import requirements are more uncertain.
Dr Erica Downs, senior research scholar at the Center on Global Energy Policy at Columbia University, told Carbon Brief she does not think it has been “definitively decided in China” what role gas will play in its energy transition, but that this role may be smaller than previously assumed.
She added that Russian oil is attractive to Chinese policymakers, as overland oil pipelines reduce China’s reliance on “vulnerable” sealane routes and Russia’s war with Ukraine allows Chinese buyers to get discounted rates on Russian barrels.
China’s increased oil and gas imports, following western sanctions on Russian oil, provided an “economic lifeline” to Russia in exchange for “securing cheap supplies”, according to the Swedish Institute of International Affairs (UI).
Imports from a politically aligned partner are “vital” for China’s energy – and, therefore, economic – security, according to Chatham House.
Not changing with the times
However, this partnership could wane. The UI study argued that China could adopt a “more cautious approach”, depending on geopolitical and economic developments.
Downs told Carbon Brief that, in the near-term, China will remain reliant on oil and gas imports, but that China “has to decide how much…they want to be dependent” on Russia.
If Chinese demand for fossil fuels falls, she said, “Russia becomes a lot less important to China as an economic partner”, although the political partnership remains useful to both.
Despite “buried” statements on clean energy in Sino-Russian agreements, Downs noted, the two countries are not increasing tangible cooperation on non-fossil fuel energy – in stark contrast to increasing Chinese clean energy cooperation with Saudi Arabia, for example. She added:
“[Sino-Russian energy cooperation] is really a hydrocarbon story…I’m not really seeing the level of activity that I’m seeing [from] Chinese companies in other parts of the world in the renewable space.”
Watch, read, listen
‘BUSINESS OPPORTUNITY’: A Reuters investigation found that Japan, France, Germany, the US and other wealthy nations have reaped “billions of dollars” from a programme designed to help developing countries reduce emissions and adapt to extreme weather.
CLIMATE FUNDING: Climate Change News reported that “unsafe housing for cyclone survivors in Malawi, funded by a suspected fraudster”, adds weight to the need to operationalise the UN loss and damage fund.
HUMAN FOLLY: HARDTalk interviewed UN Intergovernmental Panel on Climate Change chair Prof Jim Skea on whether the world has missed its chance to limit warming to 1.5C.

New Zealand moves to protect business with law curtailing climate litigation
New Zealand’s parliament has adopted a controversial new law blocking a whole avenue of climate litigation and shutting down its most advanced corporate lawsuit, which has been blamed by the government for shaking business confidence and investment.
The Climate Change Response (Tort Liability) Amendment Bill, expected to take effect in the coming days after it is formally signed by the Governor-General, prevents all current and future civil claims for climate loss or harm under tort law.
Justice minister Paul Goldsmith said last week that the aim was to give businesses “certainty around their climate change obligations”, noting it would not alter the government’s responsibilities under the Climate Change Response Act 2002 nor business obligations under the Emissions Trading Scheme.
“Our response to climate change is best managed by the Government at a national level and not through piece-meal litigation in the courts,” he added in a statement.
Such litigation, he said, “risks developing a new regime that contradicts the framework Parliament has already enacted” to tackle climate change.
Goldsmith singled out a key domestic climate lawsuit brought by Northland iwi leader and activist Mike Smith against six big companies: dairy firms Fonterra and Dairy Holdings, energy firms Genesis Energy and Z Energy, New Zealand Steel and coal mining firm BT Mining. A seventh original defendant, Channel Infrastructure, was dropped after it permanently decommissioned its Marsden Point oil refinery.
Smith argued that these companies had caused him harm under public nuisance and negligence law, as well as a third breach of a duty to cease contributing to climate change that has yet to be tested domestically. He did not seek financial compensation, instead asking for the companies to immediately stop emitting or contributing to net greenhouse gas emissions.
In one of the most advanced corporate climate accountability lawsuits in the world, a trial had been scheduled for April 2027 after the Supreme Court unanimously allowed the case to continue.
Corporate lobbying in the shadows
Smith described the passing of the bill as “deeply concerning”, particularly as it coincided with the Supreme Court hearing another of his climate lawsuits. In that case, Smith v Attorney-General, he argues that the government’s response to climate change and its impacts on Māori communities in particular breaches rights to life and culture.
“That timing raises profound questions about the separation of powers and the rule of law,” said Smith. “Whatever one’s view of the merits of these cases, it is deeply troubling when parliament intervenes to remove a legal pathway while the courts are actively considering fundamental questions about climate responsibility, rights and the crown’s obligations.”
The bill – which says that no person (including the government) can be found liable in tort for emissions-related climate change effects – followed major lobbying efforts by the companies defending themselves in Smith’s lawsuit. They outlined a proposed legal amendment in a briefing note to the government in 2024.
The centre-right government has been fiercely criticised over its lack of transparency in relation to this lobbying activity. The national ombudsman recently found that the Prime Minister’s Office effectively withheld information requested by the Environmental Law Initiative about meetings, discussions and conversations regarding Smith’s case.
Green groups fail to stop bill
The bill sparked huge concern among environmental campaigners in New Zealand and elsewhere. Greenpeace Aotearoa called it a “shocking abuse of executive power” and the vast majority of submissions to a parliamentary inquiry said it should be rejected.
But in the end, it was adopted with little resistance, moving relatively smoothly through parliament, passing its third reading by 67 votes to 53. Sam Bookman, climate law lecturer at Melbourne Law School, told Climate Home News he was not surprised by this, given that the coalition government has a secure majority.
A complaint has been made to the UN special rapporteur on climate change and human rights by Smith, the National Iwi Chairs Forum Pou Tikanga and youth coalition Climate Clinic Aotearoa over what they see as the government’s heavy-handed approach. Smith is also challenging the new law in yet another lawsuit.
“Pathetic”: New Zealand plans to barely cut emissions between 2030 and 2035
Bookman thinks it “very unlikely” that such a challenge will succeed, noting that New Zealand’s constitution is firmly anchored in parliamentary sovereignty.
But the expert in climate law does not see the bill as the end of legal action in the country, noting that New Zealand has a “sophisticated climate litigation landscape with a growing number of specialist and experienced lawyers and NGOs”.
The country is also approaching its next general election in November, and some opposition parties have pledged to restore access to the courts if elected.
Amanda Larsson, global project lead on agriculture for Greenpeace International, said: “This law deserves to be tested, and I strongly encourage the international climate litigation community to unite and help defend New Zealanders’ fundamental right to hold polluters accountable before this becomes a global blueprint.”
Copycat legislation on the rise
New Zealand’s move is part of a small but growing legislative effort to shut down climate litigation around the world.
In the US, Republican politicians introduced legislation in the House and Senate in April that would shield fossil fuel firms from climate liability lawsuits. Similar laws have already been passed at state level in Tennessee, Utah, Iowa and Louisiana.
The German state of Bavaria has put forward a similar proposal to the Federal Council, aiming to block private climate claims as well as the recognition and enforcement of foreign judgments imposing such liability. There are also proposals to limit available remedies and actions in the Netherlands and Belgium.
UN General Assembly backs “climate obligations” set by world’s top court
Bookman said he expects more efforts to counter climate damages litigation and advised plaintiffs to think about how to respond, including drawing on broader support in opposing them.
“Even though it’s very hard for plaintiffs to win these types of cases, companies are very eager to avoid the expense, embarrassment and political accountability that come even with unsuccessful lawsuits,” he said.

Indonesia’s nickel production cuts are not enough to create a sustainable industry
Bhima Yudhistira Adhinegara is the Executive Director of the Center of Economic and Law Studies (CELIOS), an Indonesia-based economic think tank. Muhammad Zulfikar Rakhmat is the Director of the China-Indonesia desk at CELIOS.
Indonesia produces around 60% of the world’s nickel, a metal used to manufacture batteries for electric vehicles (EVs) – more than any other country in the world. But in 2026, the government sharply reduced how much of its nickel can be extracted from the ground.
Production quotas were reduced by around 40% this year compared to 2025. Weda Bay, the largest nickel mine on Earth, had its allowance cut by more than 70% and exhausted its full-year quota by the end of May, halting mining entirely; it cannot resume large-scale extraction until next year unless regulators grant an extension.
The policy has sparked a vivid debate in Indonesian policy circles: how can the country shift its strategy from a decade of mining vast quantities of cheap nickel to producing a high-value and low-carbon material that the rest of the world wants for EV batteries.
The cuts aren’t a silver bullet to clean up Indonesia’s nickel industry, whose smelters are powered by coal – the most polluting fossil fuels. But alongside stricter enforcement of environmental rules, it is one side of efforts to produce more sustainable nickel for a premium.
Restricting Indonesia’s nickel output
Production quotas were introduced to stop the collapse of nickel prices because of oversupply in the market. Prices had fallen more than 40% in 2023 alone and kept sliding as Indonesian supply kept growing, hitting a four-year low of around $13,900 a ton in late 2025.
Critics called the recent tightening of production quotas proof that Indonesia’s nickel strategy has failed, arguing that the industry shouldn’t need to throttle its own output to survive. But when assessed against what the policy was supposed to do – push up nickel prices – it has worked. Prices jumped to $20,000 a ton in May, the highest since 2024.
Chinese industry groups representing companies that have invested billions to mine and refine the country’s nickel were furious, warning Indonesia’s president Prabowo Subianto that the cuts put $50 billion worth of investment at risk. But much of that Chinese capital is sunk into smelters and processing plants built specifically to run on Indonesian ore, and cannot simply be moved elsewhere. That gives Jakarta more room to hold its ground than the warning suggests.
Stronger environmental enforcement
Since the start of the year, Indonesia’s forestry task force has seized more than four million hectares of land from mines and plantations operating illegally in protected forests, collecting over two trillion rupiah ($113 million) in fines.
This included 148 hectares seized from Weda Bay for lacking a forestry permit. The share of nickel produced from illegal small-scale mining also fell from about a quarter in 2022 to roughly 10% by 2024.
The crackdown responds to serious environmental damages in the nickel industry. On Obi Island, a waste pond collapsed after heavy rain in June 2025, flooding three villages and killing a resident. Internal company tests found chromium-6 – a carcinogen – in the water, in quantities far above the legal limit. The footprint of another mine near Raja Ampat, which is home to some of the world’s richest coral reefs, grew 60-fold in just eight years.

The market is responding to early cleanup efforts. Low-carbon nickel now sells for a real premium, roughly $18,800 to $19,300 a ton compared with $17,900 to $18,300 otherwise, as carmakers seek to source cleaner materials to comply with the European Union’s new emissions rules for imports.
In turn, this is incentivising the industry to do more to green its operations. Vale Indonesia’s smelter in South Sulawesi now runs almost entirely on hydropower, for example.
None of this addresses coal use, however. Major Indonesian nickel producers still emitted an estimated 15 million metric tons of greenhouse gases in 2023. Indonesia may be cracking down on illegal mining and rewarding cleaner producers but it is still running its mines on the dirtiest fuel available.
Unequal benefits
For Indonesia to truly benefit from producing cleaner and high-value nickel, it needs to reap the economic benefits too. Although the industry has boosted the country’s economic growth, the reality on the ground tells a different story.
Konawe in Southeast Sulawesi is home to a major smelting complex. Growth in the district jumped from 6% to 22% between 2015 and 2023, driven almost entirely by the nickel industry, according to a study by the Lowy Institute study. At the same time, poverty levels increased slightly and unemployment remained unchanged.
In Halmahera, another epicentre of the nickel industry, spending by the poorest fifth grew just 5% between 2019 and 2022, compared with 28% for the wealthiest fifth, according to a separate study.
Part of the reason for this inequality is the system for transferring mining royalties to district authorities where the mines are located. In theory, they are entitled to the largest share. But in practice, payments are delayed, companies routinely dispute what they owe and royalties are pooled and distributed across a larger area.
The Natural Resource Governance Institute has found that decentralisation handed local governments power to approve new mines faster than they could build their capacity to manage them. Higher output raises national income on paper, but local governments remain constrained by fiscal rules and infrastructure costs that scale with mining.
None of this makes the 2026 quota cuts a mistake. Indonesia has every right to defend its pricing power over a resource it controls. But limiting extraction isn’t going to fix underlying issues around environmental enforcement and revenue-sharing. That requires rules that are consistently enforced, royalties that reach communities living by the mines, and a plan to wean smelters off coal.

Risk of “catastrophic” oil spill reaching Kimberley coast found in Woodside’s Scott Reef gas drilling plans
SYDNEY, Monday 24 August 2026 – New analysis of Woodside modelling released by Greenpeace Australia Pacific and Environs Kimberley has revealed the oil and gas corporation’s plans to drill at Scott Reef could cause an oil spill up to 30 times bigger than the 2009 Montara disaster, impacting the Kimberley coastline and reaching as far as Indonesia.
The new analysis details the “catastrophic” oil spill risk put to environmental regulators for approval by Woodside in its Browse to North West Shelf Project (Browse) plans, the worst-case scenario being a blowout directly below Scott Reef, polluting whale migratory pathways and covering isolated turtle nesting ground with oil condensate.
An FOI application (F348) revealed the federal environment department (DCCEEW) asked offshore oil and gas regulator NOPSEMA to look into the oil spill risk in 2025. NOPSEMA’s response to the application refused access to its report, and one document shows DCCEEW sought further advice this year.
Greenpeace and Environs Kimberley are calling on the Federal Government to publicly release the NOPSEMA report given the risk of an uncontrolled release of oil condensate from directly below Scott Reef.
Hannah Schuch, Senior Campaigner at Greenpeace Australia Pacific, said: “Woodside is aware that drilling at Scott Reef risks a massive oil spill that would have severe, far-reaching consequences. It appears environmental regulators are aware too.
“The state and federal governments need to take this risk from Woodside’s drilling plans seriously, as they could end up allowing the worst oil spill in Australian history.
“The pygmy blue whales that migrate up and down the WA coast with their newborns each year could be swimming and feeding in toxic, oil-slicked water. Woodside’s proposal to drill at Scott Reef is an environmental disaster waiting to happen, and the WA and federal governments have one surefire way to prevent catastrophe — reject Browse.”
Martin Prichard, Executive Director at Environs Kimberley, said: “A catastrophic oil spill by Woodside would be disastrous not just for marine life in the area but also for the Kimberley’s $500 million tourism industry.
“The state and federal governments will see five marine parks on the Kimberley coast included in the risk area of a catastrophic Woodside oil spill.
“The Montara oil spill was disastrous for West Timor with the toxic oil destroying seaweed farmers’ livelihoods. The Kimberley dodged a bullet with Montara, we were lucky the spill didn’t head our way. Myself and a crew flew over the Montara oil spill and followed it as far as we could. It was like a scene from a disaster movie.”
After the WA Environmental Protection Authority deemed Browse “unacceptable” due, in part, to oil spill risk, Woodside submitted a mitigation plan based on technology that has never been used “in anger”, a weakness stated in an independent expert review of the plan.
Professor Richard Steiner, independent oil spill expert, said: “A large offshore spill is impossible to effectively contain or recover. Historically, only 2-6% of total spill volume is recovered and the ecological injury from the release of toxic hydrocarbons in the sea can be severe, extensive, and long-term.
“Here in Alaska, government research concludes that several marine populations injured by the 1989 Exxon Valdez oil spill, including whales, fish, and seabirds, are still not recovering today, 37 years later. We should expect similar long-term ecological impacts in Western Australia if there were to be a major oil spill. The only sure way to avoid the risk of a catastrophic marine oil spill is to not develop oil and gas projects in marine environments.”
