Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Energy outlook
DEMAND SURGING: The International Energy Agency (IEA) published its annual World Energy Outlook report – a “comprehensive” summary of global energy trends – the New York Times reported. The outlet said, over the next decade, the world will add the equivalent of Japan’s annual electricity demand each year, driven by demand for new factories, electric vehicles, air-conditioners and data centres. (Axios said the IEA included a “reality check” about data centre demand, which would only make up a “small share” of growth by 2030.)
AGE OF ELECTRICITY: Reuters reported that the “world is on the brink of a new age of electricity”, with global fossil fuel demand set to peak by the end of the decade. The newswire added that “surplus oil and gas supplies could drive investment into green energy”. The Wall Street Journal said clean energy would grow faster than global energy demand, becoming the largest source of power in the mid-2030s, according to the IEA. Carbon Brief has just published an in-depth analysis of the report’s findings. (See Captured below.)
COP16 kickoff
BIODIVERSITY TALKS: The COP16 biodiversity summit begins in Cali, Colombia, on Monday. It will be the first set of UN biodiversity negotiations since the world’s nations agreed a landmark deal in 2022 to “halt and reverse” nature loss by the end of the decade.
MISSED PLEDGES: Joint analysis published on Tuesday by Carbon Brief and the Guardian showed that more than 85% of countries are set to miss the UN’s deadline to submit new nature pledges, known as national biodiversity strategies and action plans (NBSAPs).
WHAT TO WATCH: Carbon Brief’s team of journalists on the ground in Cali will host a webinar on Tuesday at 3pm UK time to discuss the key issues facing negotiators and answering questions. (Sign up for free.) Through the fortnight of the talks, they will also be scrutinising each new draft negotiating text as it lands, explaining areas of disagreement and updating Carbon Brief’s interactive text tracker.
After the storm
DEVASTATING DAMAGES: Hurricanes Helene and Milton are “likely” to each rack up costs of more than $50bn, the Associated Press reported. According to the newswire, “government and private experts” say the hurricanes could join the “infamous ranks” of Katrina, Sandy and Harvey – which are among the eight US storms to have ever caused damages of more than $50bn.
PAYOUTS: The US Small Business Administration has exhausted funds for its disaster loan program following increased demand from Hurricane Helene, Reuters warned. Officials said the program needs about $1.6bn amid heightened demand following Hurricane Helene, according to the Hill. The Financial Times estimated that Milton alone will lead to about $36bn of insurance payouts for the private sector.
Around the world
- DIRTY ENERGY: Burning household rubbish to make electricity is now the “dirtiest way the UK generates power”, BBC News reported.
- COP BID: Australia has launched a bid to host the COP31 climate summit in 2026 in Adelaide, according to the Guardian.
- FINANCE FAIL: The EU unveiled its negotiating stance for the COP29 climate talks next month, but did not address how it will boost funding for developing countries, according to Bloomberg.
- CURBING COAL: The US Supreme Court allowed the Environmental Protection Agency to move ahead with its plans to limit carbon emissions by power plants, despite a pending challenge from 27 mainly-Republican states, the New York Times reported.
- WARNING MESSAGE: Activist group Friends of the Earth warned the UK government to drop its support for a Mozambique gas project “embroiled in allegations of abduction, murder and rape”, said Politico.
- WIND POWER: A Chinese company developed the world’s “most powerful” floating offshore wind turbine with a capacity of 20 megawatts, state news agency Xinhua said.
60%
Global increase in forest fire carbon emissions over 2001-23, according to a new paper in Science.
Latest climate research
- Recent floods that killed at least 244 people in Nepal were driven by rainfall made “about 10% more intense” by human-caused climate change, according to a rapid attribution study.
- Drought and aridity are already having a “significant impact” on internal migration – especially in arid and “hyper-arid” regions of southern Europe, South Asia, Africa and the Middle East and South America – new research found.
- Many people in the US are experiencing “psychological distress” from climate change, but those who do are more involved in collective climate action, a new study said.

Electricity generation from solar is set to quadruple by 2030, sending coal power tumbling and becoming the world’s largest source of electricity by 2033, according to Carbon Brief analysis of the International Energy Agency’s World Energy Outlook. The report finds that global CO2 emissions are set to peak “imminently”, as the “age of electricity” sends fossil fuels into decline. See Carbon Brief’s in-depth coverage of the report.
Spotlight
Is global warming ‘accelerating’?
A recent “surge” in global warming is not statistically “detectable”, according to a study published this week. But does this mean it is not happening? Carbon Brief speaks to the lead author of the study and explores the debate on a warming acceleration.
Global temperatures are soaring. Last year was the hottest year on record, with global surface temperatures reaching 1.34-1.54C above pre-industrial levels. But 2024 is already setting blistering new records and is expected to knock 2023 off the top spot.
Against this backdrop of ever-worsening heat, a new study in Communications Earth and Environment used statistical methods to see whether an acceleration in global warming could be formally detected.
The authors find a “changepoint” in the rate of warming around the year 1970, but find no “statistically detectable” acceleration since then.
Dr Claudie Beaulieu is the paper’s lead author and an associate professor in the Ocean Sciences Department at UC Santa Cruz. She told Carbon Brief: “If an acceleration in global warming is occurring, the size of that acceleration is either too small or too recent to robustly detect it in globally-averaged surface temperature records.”
However, some scientists questioned the methods used in the study. Prof Richard Allan, a professor of climate science at the University of Reading, said the surface warming data used in this study is “influenced by natural variation”. He argued that “when all lines of evidence are scrutinised” – such as satellite data and ocean measurements – “it is apparent that climate change is accelerating rather than continuing steadily”.
Carbon Brief’s climate science contributor, Dr Zeke Hausfather, published a factcheck earlier this year on the acceleration in global warming. Assessing observations and climate model output, he concluded that “that there is increasing evidence of an acceleration in the rate of warming over the past 15 years”.
Beaulieu told Carbon Brief that present-day discussion about an acceleration in warming is similar to the debate over a warming “hiatus” about a decade ago. She continued:
“Back then, also using statistical methods, we showed that a ‘hiatus’ in warming was not detectable. With hindsight of more years of observations it is now obvious warming had just continued leading to the record heat of 2023. We need to keep monitoring.”
Dr John Kennedy is the co-chair of the World Meteorological Organisation (WMO) expert team on climate monitoring and assessment and scientific coordinator for the annual WMO State of the Global Climate reports.
He warned that this statistical method can mean waiting many years for warming – or a lack of warming – to be detectable. In a blog post earlier this year, Kennedy wrote:
“One thing that became clear during the ‘hiatus’ is that this kind of analysis is the kind of thing you do when you’re set (for whatever reason) on being the last person to know there is a hiatus.”
He added: “There are good physical reasons to expect an increase in the underlying warming.”
Beaulieu does not refute that warming might be accelerating. She said that “the point of the paper is that it will take additional years of observations to detect a sustained acceleration”.
Watch, read, listen
CLIMATE LINGO: Author and climate change activist Genevieve Guenther joined the Drilled podcast to discuss her new book, The Language of Climate Politics, which digs into rhetorical devices that she says are being used to slow or block climate action.
FAILING SINKS: “Is nature’s carbon sink failing?” asked a feature in the Guardian. The article warned that forest, plants and soil absorbed almost no carbon in 2023, and asked whether this “could rapidly accelerate global heating”.

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

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

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