For the second time since the Paris Agreement on climate change was adopted, the US this week formally withdrew from the global pact following a 12-month mandatory period since President Donald Trump announced he would pull his country out on his first day in office in January 2025.

Since then, the US has axed most of its international climate funding and this month said it would exit the UN climate convention (UNFCCC) – which underpins the UN climate process and the Paris Agreement – the Intergovernmental Panel on Climate Change (IPCC), which is the world’s most authoritative climate science body, and the Green Climate Fund (GCF), the world’s biggest multilateral climate fund.

Trump to pull US out of UN climate convention and climate science body

As the Trump administration turns its back on the UN climate regime, UN climate chief Simon Stiell described the move as a “colossal own goal”, while the GCF – to which the US has failed to deliver billions of dollars in promised support – said the country would lose its board seat but operations would continue.

Climate diplomacy experts say some of the changes announced by the US president could remain symbolic or be reversed in the future, while warning that the reputation of the world’s second-biggest emitting country could suffer a big hit in the long term.

Other countries may follow US Paris exit

Marta Schaaf, Amnesty International’s climate programme director, said the US’s second exit from the Paris Agreement on January 27 (the first was during Trump’s first term) “sets a disturbing precedent” that could instigate a “race to the bottom”, encouraging other countries to leave.

“The US is one of several powerful anti-climate actors but as an influential superpower, this decision, along with acts of coercion and bullying of other countries and powerful actors to double down on fossil fuels, causes particular harm and threatens to reverse more than a decade of global climate progress under the agreement,” she said in a statement.

So far no other signatories have publicly announced they will quit the 2015 climate agreement, but Israeli media recently reported that the country is discussing a withdrawal under pressure from the US. Last year, Argentina also hinted at a possible exit but did not follow through.

COP30 chief calls for two-tier climate system to speed up action beyond consensus

COP30 President André Aranha Corrêa do Lago said himself that in the months leading up to last year’s UN climate conference in Brazil, there was “a lot of noise about possible additional exits”, after the world’s largest economy said it would withdraw.

The Trump administration has been called out in other UN processes, after being accused of employing “bullying” tactics at the International Maritime Organization (IMO) to persuade smaller countries to vote against the entry into force of a green shipping deal. This pressure resulted in a delayed decision.

Allie Rosenbluth, Oil Change International’s US campaign manager, said the US withdrawal from the Paris Agreement “is a betrayal of the communities at risk from climate disaster, especially those on the frontlines of the crisis in the Global South”.

Legal uncertainties around UNFCCC withdrawal

This January, in an unprecedented move, the White House also announced the US would leave the broader UN Framework Convention on Climate Change (UNFCCC). This would take effect one year after formally notifying the UN, which it had yet to do as of the time of publication.

The UNFCCC could be harder to rejoin than the Paris Agreement – which was last done through an executive order issued by former President Joe Biden – because the US Senate first gave unamimous “advice and consent” for ratification of the UNFCCC in 1992, making the legal situation more complex.

Some experts believe the US would need Senate authorisation to formally withdraw from the UNFCCC, and there are questions around whether the move would be legal at all.

Trump’s presidential memorandum says that “for United Nations entities, withdrawal means ceasing participation in or funding to those entities to the extent permitted by law”. To all intents and purposes, the US had already disengaged from the UN climate process during Trump’s first year in office, cutting funding for the UN’s climate body and not sending a delegation to COP30.

However, if the US does not formally notify the UN of its withdrawal from the UNFCCC, that could potentially ease legal concerns for the Trump administration, according to Michael Gerrard, climate change law professor at Columbia Law School.

Could the US rejoin the UNFCCC?

Gerrard told Climate Home News that if the Trump administration does not officially withdraw from the UNFCCC, “then I don’t see a legal obstacle to a subsequent administration resuming funding and participation”. “Even if the US does formally withdraw now, a new president might well be able to rely on the prior consent in rejoining; that issue has never been decided by the Supreme Court,” he added.

Sue Biniaz, the US State Department’s Principal Deputy Special Envoy for Climate until January 2025, and Jean Galbraith, professor at the University of Pennsylvania Carey Law School, wrote on the Just Security blog that the mainstream legal view is that the president may constitutionally withdraw the US from a Senate-approved treaty where – as here – the withdrawal is lawful under international law and neither the Senate’s resolution of “advice and consent” nor a congressional law has put limits on withdrawal.

    Under international law, they added, rejoining is straightforward. For the UNFCCC, a state can become a party 90 days after depositing its instrument of ratification or accession, and following that, the US could rejoin the Paris Agreement, which would take 30 days after the deposit of its instrument.

    From the perspective of domestic law, the two climate law experts argued that the original Senate resolution remains in effect (unless repealed by the Senate) and provides the legal authority needed for a future president to rejoin the UNFCCC. He or she could also seek a second round of “advice and consent”, ask Congress to approve rejoining, or potentially join the UNFCCC under the president’s independent constitutional powers, they added.

    Loss of US leadership and credibility

    Irrespective of whether the White House does move to rejoin the UN climate regime at any point, analysts said the Trump administration’s hostile attitude and disengagement has damaged the standing of the US when it comes to global climate action and the energy transition.

    Biniaz and Galbraith wrote that the world is used to the US “flip-flopping on climate”, because it refused to ratify the Kyoto Protocol and quit the Paris Agreement once before, but “withdrawal from the entire regime takes US abdication of climate leadership to a new level”.

    Though many countries may be relieved that the Trump administration is not participating given its current policies, they said: “in the longer term, US absence could have a negative impact on the effectiveness of the regime and the willingness of other countries to take ambitious action.”

    Nikki Reisch, climate and energy director at the Center for International Environmental Law, warned that “it will not be easy for the US to regain credibility or leadership on climate.”

    While an “informal withdrawal” from the UNFCCC may “avoid some paperwork” and avoid potential lawsuits, she said it would not “insulate this administration from scrutiny and legal challenge on other grounds, particularly as it continues to unwind climate progress, dismantle environmental protections, and expand production of the fossil fuels”.

    Reisch noted that US states and local governments have been making efforts to “fill the void where the federal government has abdicated its duties”. “Other countries, too, should see the Trump administration’s retreat as an invitation to step up, stand together and move forward,” she added.

    Coles, Woolworths failing on deforestation commitments 

    Published

    on

    SYDNEY, Wednesday 26 August 2026 — New 2026 Sustainability Reports released by supermarket giants Coles and Woolworths this week demonstrate the retailers are failing on their commitments to end deforestation in their supply chains.

    Adele Chasson, Nature Policy Lead at Greenpeace Australia Pacific said:

    “These so-called sustainability reports are revealing. Despite their public commitments in 2024 and 2025, neither Coles nor Woolworths have taken deforestation-linked beef off their shelves. Meanwhile, bulldozers continue to tear up forests and bushland, pushing wildlife closer to extinction and causing mass toxic runoff to flow into the Great Barrier Reef. Millions of native animals like koalas are losing their homes to beef pastures each year, while the big supermarkets put off action.

    “Australians would be shocked to know that beef on the shelves of our biggest supermarkets could be pushing threatened species to the brink of extinction. Collectively Coles and Woolworths have made more than $2 billion in profits in the last year, profiting from the destruction of wildlife and precious Australian nature. Coles and Woolworths owe it to shoppers to deliver on their promises and end deforestation in their supply chains now.

    “As big beef buyers, Coles and Woolworths have an essential role to play in keeping Australia’s unique forests standing. They can help stop the Great Barrier Reef from being poisoned by runoff and protect iconic forest wildlife by taking deforestation off their shelves. It’s time these big companies put their money where their mouths are and follow through on their promise of sourcing and supplying deforestation-free beef.”

    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.
