An essential guide to the week’s key developments relating to climate change.

This week

COP16 kicks off

HOLA CALI: The largest ever UN biodiversity summit, COP16, is officially underway in Cali, Colombia. At the talks, countries will grapple with how to put the Kunming-Montreal Global Biodiversity Framework – often described as the “Paris Agreement for nature” – into action, alongside debates on finance for developing countries and how to best share the benefits from genetic information.

TRACKING NEGOTIATIONS: Carbon Brief has produced an interactive grid of where each party stands on the key negotiating issues and a live tracker of the texts under negotiation. On Tuesday, Carbon Brief’s team of five journalists on the ground in Cali held an online webinar on the key issues up for discussion at the summit. A recording is available.

Around the world

  • CLIMATE PLANS: The UK must decide “how far and how fast” to cut emissions amid preparations to release a new national climate pledge at the COP29 climate summit in November, the Guardian reported. Carbon Brief understands that the US, Brazil and UAE are planning to do the same, three months before the deadline. 
  • LOBBYING: An “influential” group of 30 oil and gas producers drafted “detailed plans” for “dismantling” key US climate rules after the upcoming presidential election, the Washington Post reported. Members of the group were “aggressively pursued for campaign cash by Donald Trump”, the newspaper noted. 
  • CUBA CHAOS: At least six people were killed as Hurricane Oscar brought heavy rainfall to Cuba, according to the New York Times
  • ENERGY BOOST: South-east Asia must accelerate clean-energy investments to $190bn by 2035 – around five times current levels – to meet climate goals, according to a new International Energy Agency (IEA) report covered by Reuters

Latest climate research

  • The extreme floods that hit Sudan in August were made nearly 20% more intense by human-driven climate change, according to a new World Weather Attribution analysis.
  • Research in the Proceedings of the National Academy of Sciences found that a 1% increase in deforestation in the Brazilian Amazon was associated with a 6.3% jump in malaria cases the following month.
  • Over the past 30 years, polar bears have been increasingly exposed to a range of pathogens, due in part to the loss of sea ice habitat and rapid warming in the Arctic, a new PLOS One study said.

Captured

Greenhouse gas emissions remain far off track to meet global climate goals, according to the UN Environment Programme’s (UNEP) 2024 emissions gap report covered by Carbon Brief. The chart above, based on a figure from the report, shows how emissions will change by 2035 under current policy and under current national climate plans, known as “nationally determined contributions” (NDCs). The chart compares this with the emissions reductions needed by 2035 to put the world on track with a scenario where global temperatures are kept to 1.5C (red) or 2C (pale red).

Where countries stand on reversing nature loss

This week, Carbon Brief reports on how countries plan to get back on track after the majority of them missed a deadline to release new nature pledges ahead of COP16.

In a cold and snowy Montreal in the depths of December 2022, countries agreed to the landmark Kunming-Montreal Global Biodiversity Framework (GBF), often referred to as the “Paris Agreement for nature”.

The GBF is a list of four goals and 23 targets that collectively aim to halt and reverse biodiversity loss by 2030 and to put Earth “in harmony with nature” by 2050.

At the Montreal talks, countries pledged to release new national plans to lay out how they plan to implement the goals and targets within their borders.

These plans are known as national biodiversity strategies and action plans, or “NBSAPs”.

Under the GBF and its underlying documents, countries agreed to submit new NBSAPs by the COP16 biodiversity summit, which is currently taking place in Cali, Colombia.

Carbon Brief analysis shows that just 30 countries and the EU met the deadline to submit an updated NBSAP ahead of COP16.

Since then, a further five countries have published new NBSAPs, including COP16 host Colombia.

That leaves 162 parties that are yet to submit updated NBSAPs.

Countries that were unable to meet the deadline to submit NBSAPs ahead of COP16 were requested to instead submit national targets. These submissions simply list biodiversity targets that countries will aim for – without an accompanying plan for how they will be achieved.

As of 25 October, 113 parties had submitted national targets.

Next steps

One of the major tasks for negotiators in Cali will be to decide how to move forward after the majority of countries failed to produce new NBSAPs ahead of the talks.

On Thursday, a draft decision submitted for review by COP16 president and Colombian environment minister Susana Muhamad laid out the next steps for countries when it comes to NBSAPs.

The text still contains some brackets, meaning countries will need to negotiate the finer details before it can be officially adopted.

The draft “urges” countries that have not yet done so to release new NBSAPs “as soon as possible”. (In UN language terms, “urges” is stronger than “invites” or “encourages”, but not as strong as “requests” or “instructs”.)

Eyebrows may be raised at the failure to include a specific timeframe for when laggard countries should submit new NBSAPs.

One NGO observer told Carbon Brief that they had hoped to see the language say “as soon as possible, but no later than the end of 2025”, adding:

“Generally having a clear deadline is good to keep countries to account. ‘As soon as possible’ is commonly understood as ‘really really soon’ and we can only hope that parties see it that way too.”

The text also “requests” the Global Environment Facility (GEF), a major multilateral environmental fund, “provide[s] timely support to all eligible parties, aligned with national circumstances and needs, upon request, to enable them to” release new NBSAPs.

It comes after developing countries said that a lack of timely funding from the GEF had prevented them from being able to produce new biodiversity plans on time.

Watch, read, listen

‘BLENDED’ FINANCE: Writing in Le Monde ahead of COP29, Mette Frederiksen and Mia Mottley, the prime ministers of Denmark and Barbados, respectively, argued in favour of scaling up state-backed “blended” finance instruments to channel private investment for climate action.

COP16 OUTSIDER: Vox examined why the US is the only country in the world, other than the Vatican, to refuse to join the UN biodiversity convention.

PANTANAL JAGUARS: A podcast by the Brazilian Report covered how extreme fires in Brazil’s Pantanal wetlands are affecting jaguars, “the biome’s most emblematic species”.

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.
