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.

Chart showing that the UK car market 'over-complied' with the ZEV mandate in 2024

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 Nagarrecognised 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.

New Zealand moves to protect business with law curtailing climate litigation

Published

on

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 

    Published

    on

    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

        Published

        on

        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.”
