This week

Africa’s second climate summit

‘NOT CHARITY’: At the second Africa climate summit held in Addis Ababa in Ethiopia this week, leaders “chastised developed nations for failing to honor [climate finance] pledges” and said they will “tap the private sector” to help fill the gap, Bloomberg reported. In a joint statement, African leaders said that providing climate finance is “a legal obligation and not charity, as anchored in the UN Framework Convention on Climate Change and its Paris Agreement”, according to the outlet.

SOLUTIONS CENTRED: Climate Home News reported that Ethiopian president Taye Atske Selassie told the closing ceremony on Wednesday the summit had repositioned Africa “not as victims of a crisis it never created but as a global centre for climate solution, renewable energy and green growth”. The outlet added that the joint leaders’ declaration called for “strengthened and sustained support” to scale up African-led climate initiatives, such as the 8,000km Great Green Wall across the Sahel and the African Forest Landscape Restoration Initiative.

Around the world

  • ‘SILLY’: Chris Wright, the climate-sceptic US energy secretary, has dismissed the impacts of climate change as “not incredibly important” and described the Paris Agreement as “silly”, reported the New York Times. Elsewhere, the group of “climate contrarians” behind Trump’s misleading climate report have been “disbanded” following a lawsuit challenging their appointment, CNN reported.
  • CHINA BOOM: The world’s fossil-fuel use could begin to drop by 2030 as a result of China’s “rapid adoption of renewables and its increasing reliance on electricity”, Bloomberg reported, citing a new study by thinktank Ember.
  • NDC INDECISION: EU member states are still “wrangling” over the bloc’s overdue 2035 climate target, “with no sign of agreement”, according to a leaked draft text seen by the Guardian.
  • TRADE SPOTLIGHT: Brazil plans to propose a new forum for governments to discuss how climate policy affects trade at the next World Trade Organization meeting next week, according to Reuters.
  • UK PUBLIC POLLED: In a frontpage story, the Times covered new polling it commissioned, reporting that the number of people who think the dangers of global warming are exaggerated has increased by more than 50% in the past four years, from 16% to 25%. [Polling experts have criticised the framing of the Times coverage, noting that a large majority of the public still back net-zero.] 

£797 million

The record amount of UK climate aid spent on nature last year – largely due to an increase in spending on carbon offsets, according to new Carbon Brief analysis.

Global map showing that more than 200 'major' heatwaves have been recorded around the world in the 21st century

A new study used “extreme event attribution” to assess the impact of climate change on all 21st-century heatwaves that were classified as “major disasters”. It found that global warming linked to the world’s biggest 180 oil and gas companies made all 213 heatwaves analysed more intense and frequent. Meanwhile, one-quarter of the heatwaves would have been “virtually impossible” without human-caused global warming. The paper, covered by Carbon Brief, analysed 213 heatwaves over 2000-23 that were recorded in the EM-DAT database of “major disasters” . These heatwaves are shown in the map above.

How scientists can tackle net-zero backlash

This week, Carbon Brief asks climate scientists attending a summit at the University of East Anglia, UK how researchers can better combat net-zero misinformation.

It comes as the UK’s right-wing political parties and press are increasingly making misleading claims about net-zero.

Asher Minns, executive director of the Tyndall Centre for Climate Change Research at the University of East Anglia

The whole discourse around net-zero has become something that it was never intended to be. It’s a quite specific scientific concept that came out of the IPCC 1.5C report, following up on [the] Paris [Agreement], so it actually has quite a specific definition, but it has actually become a phrase that is being used really just to mean “removing CO2” or “saving energy”, even. It’s become this kind of huge term across public, across media, across policy, that everybody can just pin what they mean to “net-zero” without actually referring to what it actually is, which is absolute zero emissions, getting CO2 out of the atmosphere. The fact that there is a government department called “net-zero” isn’t great for that public discourse, for public understanding, and that’s why we’ve got a bit of a backlash. I don’t think we need to necessarily abandon the phrase net-zero, but I think we should just talk about clean energy and concepts that people have a chance of hanging onto, rather than something that’s really quite difficult.

Prof Corinne Le Quéré, Royal Society research professor of climate change science at the University of East Anglia

I think narratives about the way that we present climate action can be very negative, and, in fact, we do climate action all the time. We’ve cut emissions by half in the UK and most people haven’t realised that this is happening. Just talking about climate change in the way that there are things that you can do that are desirable and have benefits for you. Of course, the government needs to make climate solutions accessible to everybody. But improving the narratives about how we talk about climate change, that would be, for me, a small thing that we could do.

Prof Hayley Fowler, professor of climate change impacts at Newcastle University

I don’t think we can do it alone. I think we try to do everything alone and I don’t think that’s the right approach. My personal opinion is we need to be collaborating with key influencers and celebrities, quite honestly, who can actually get that message across to the people who need to hear that message. I think we need probably a few key spokespeople. And I don’t think they should be scientists, but they should have simple and clear scientific messages that they convey. There’s lots of misinformation and it’s conveyed in very clear ways with simple messaging. Often climate science is really, really complicated and that’s why people just don’t understand it, they don’t understand the jargon surrounding it and, therefore, perhaps they are more likely to understand the simple messages that come from the climate deniers.

Dr Ruth Wood, senior lecturer in environment and climate change at the University of Manchester

I find it quite challenging to work out how to engage in those discussions because they’re taking place in forums that I’m not at. Do we need a groundswell of voices around supporting net-zero, which have the same level of media savviness of the anti net-zero groups? If we had their same ability to mobilise and get the message out there, maybe that would counter some of their narratives. The gap between science and communication is a huge challenge.

Prof Charlie Wilson, professor of energy and climate change and senior research fellow in the Environmental Change Institute at the University of Oxford

I guess that part of the answer is how we’ve always done it, which is forceful rebuttals and corrections with appropriate evidence. The second bit is like learning how the algorithms work to promote both information, as well as misinformation. This misinformation is being amplified by algorithmic preferences expressed through social media platforms, which emphasise juicy clickbait-type stuff.

Watch, read, listen

FIXING TOMORROW: Climate scientist Dr Kimberly Nicholas and the NGO Project Drawdown released an evidence-based online guide for how individuals can take actions to address climate change.

‘WAR ON SCIENCE’: Bloomberg had a special feature on how Donald Trump’s “war on science” is crippling the US.

CLIMATE IN COURT: The New York Times unpacked how and why a group of students from the Pacific Islands took a climate case to the International Court of Justice.

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.
