Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.

This week

Deadly flooding

VALENCIA FLOODS: Spain is facing its worst flooding “in generations”, with more than 158 people killed in its third-largest city, Valencia, BBC News reported. On Thursday, more than 1,200 emergency staff worked to rescue people “as rains continued to threaten parts of the country”, the broadcaster said. An editorial in Spanish newspaper El País described the event as “a painful reminder that Spain is on one of the front lines of the climate crisis”.

CLIMATE ATTRIBUTION: The Associated Press reported that, according to a “rapid but partial” attribution study by World Weather Attribution, climate change “made Spain’s rainfall about 12% heavier and doubled the likelihood of a storm as intense as this week’s deluge of Valencia”. The Financial Times reported that sea surface temperatures “far above normal levels” in the Mediterranean helped to fuel the storm.
NEW DANGER: Meanwhile, Tropical Storm Trami has triggered devastating floods and landslides in the Philippines, CNN reported. The outlet quoted president Ferdinand Marcos, who said: “This is climate change. This is all new, so we have to come up with new solutions.” Authorities have reported at least 150 deaths due to the storm and a subsequent typhoon that has struck the region, according to the Philippine Star. Meanwhile, Taiwan also faced its largest typhoon in decades, the Guardian reported.

UK climate plans

CLEAN ENERGY BOOST: The first budget of the new UK Labour government contained plans to “beef up” investment in its “clean energy mission”, BusinessGreen reported. The website pointed to new fiscal rules to boost public spending on “green infrastructure”, plus investment in carbon capture and storage (CCS), green hydrogen and electric car supply chains.

GREEN BUDGET?: The Guardian said “reactions were mixed” on how “green” the budget was. The newspaper noted that, despite higher taxes on air passengers, the government was criticised for maintaining a “freeze” on fuel duty for petrol and diesel and loosening a cap on the price of bus tickets. Carbon Brief has published a rundown of the budget’s key climate and energy announcements.
NEW GOAL: Meanwhile, the UK government’s climate adviser the Climate Change Committee (CCC) has recommended that the nation should make an international pledge to cut its emissions to 81% below 1990 levels by 2035, according to the Press Association. The advice aligns with the UK’s existing domestic target, the Financial Times added. Carbon Brief covered the CCC’s advice, which will influence the target the UK is expected to present at the upcoming COP29 climate summit.

Around the world

  • BAD RECORD: Greenhouse gases in the atmosphere reached “record” levels in 2023, with carbon dioxide (CO2) at a concentration last seen a few million years ago, according to new World Meteorological Organization figures covered by BBC News.
  • NO DEAL: The EU has imposed tariffs on Chinese-made electric vehicles after China failed to secure a deal to halt their passage, according to the South China Morning Post. In response, Reuters reported that China has told carmakers to halt big investments in European countries that support the tariffs, including France and Italy.
  • RISING SEAS: At a meeting in Samoa, Commonwealth nations agreed on an “ocean declaration”, which recognised existing maritime boundaries in nations that lose land to sea-level rise, according to the Associated Press.
  • FAKE COP: “Apparently fake” social media accounts are being used to boost Azerbaijan’s hosting of COP29, according to a Global Witness investigation reported by the Guardian. The accounts have been drowning out online criticism of the nation’s poor record on human rights, it added.

8.3%

The proportion by which EU greenhouse gas emissions fell in the past year – the sharpest drop since the pandemic, but “still not on track” for its climate targets, reported EuroNews.


Latest climate research

  • A new study in the journal npj Climate and Atmospheric Science suggested that more than half of the 60,000 deaths caused by Europe’s summer heatwave of 2022 can be attributed to global warming.
  • A global area of forest bigger than Mexico has the potential for natural forest restoration, which could store more than 23bn tonnes of carbon over the course of three decades, according to new research published in Nature.
  • Only one in seven news articles published in the English-language press in India about a 2022 heatwave mentioned the links to climate change, new research in Environmental Communication found. The figure was even lower for articles written in Hindi, Telugu and Marathi, it added.

China's wind and solar growth continues to break records in 2024

Additions of new solar and wind generating capacity in China continue to break last year’s records, according to new analysis for Carbon Brief by Lauri Myllyvirta, lead analyst at the Centre for Research on Energy and Clean Air. The growth in China’s solar-power output this year alone is on track to equal the total power generation of Australia or Vietnam in 2023, based on growth rates during the first nine months of the year. The wider analysis by Myllyvirta found that China’s emissions remained flat in the third quarter of the year, leaving open the possibility that its emissions could drop in 2024.

Spotlight

Coming to consensus in Cali?

This week, Carbon Brief reports on the ground in Cali, Colombia, as the COP16 biodiversity talks inch towards their finale.

Tensions are running high and energy is running low as COP16 nears its end, with plenary sessions dragging on long into the nights.

Connectivity issues have plagued the two weeks of the summit, with WiFi signals shaky at best. Translation services have also proven cumbersome in both negotiating rooms and the press centre. Countries with small delegations have complained of being forced to prioritise certain negotiation tracks, while being shut out of others due to a lack of capacity.

Rather than coming towards consensus in the summit’s final days, observers tell Carbon Brief, countries are seemingly entrenching their positions even further.

In a statement shared with Carbon Brief, Oscar Soria, an activist with the Common Initiative and a veteran COP-goer, said:

“What we are seeing at this COP is an unprecedented high level of distrust between developing and developed countries.”

With the talks scheduled to end on Friday, Carbon Brief analysis shows that there are still nearly 700 brackets denoting areas of disagreement remaining in the decision texts. (Biodiversity COPs tend to run over their scheduled finish time.)

Below are four of the key issues negotiators are tasked with addressing – and how progress has been made on each.

Finance

Negotiations around finance at COP16 fall under two tracks: mobilising funds; and the financial mechanism for disbursing them.

Developing countries are unsatisfied with a decision at COP15 to create a Global Biodiversity Framework Fund – hosted at the Global Environment Facility in the US – and would rather see a fund that is governed by the COP itself, while developed countries want to maintain the status quo.

On resource mobilisation, money has been slow to trickle in, with additional pledges made at the summit towards the new fund totalling just $163m.

Carbon Brief understands that it is looking increasingly likely that parties will agree to revisit the issue during intersessional meetings next year.

Digital sequence information

The use of genetic resources, known as digital sequence information (DSI), is one of the key issues at COP16 – and is tied in closely to the fights around finance.

Biodiverse countries, many of whom are in the global south, want mandatory payments from companies that profit from genetic code sourced within their borders (for example, genes that are used in drug development).

Countries with strong pharmaceutical and other industries are pushing for voluntary payments only. As of Thursday evening, both options remained on the table.

Indigenous rights

Another key topic at COP16 is how to recognise the contributions of Indigenous people, who play an outsized role in protecting biodiversity globally.

In Cali, countries have agreed to adopt a programme of work to implement Article 8(j) of the Convention on Biological Diversity (CBD), which deals with respecting and preserving Indigenous knowledge.

However, Indigenous representatives are also calling for negotiators to agree to a new subsidiary body on Article 8(j), with “a mandate to provide advice” to the CBD.

Monitoring framework

In 2022, countries agreed to the Kunming-Montreal Global Biodiversity Framework, a landmark deal often described as the “Paris Agreement for nature”.

In Cali, negotiators have been tasked with coming up with a set of metrics that can be used to monitor countries’ implementation of the framework.

Discussions so far have been slow, but productive, observers told Carbon Brief.

The framework consists of sets of both mandatory and optional indicators, along with an annex containing technical details.

The general sense is that the monitoring framework that is being negotiated is not perfect, but the need to come to a decision – so countries can monitor their progress ahead of a “stocktake” at the next COP – means parties should agree to the framework here, with a promise to revisit and revise it going forward.

(Carbon Brief will publish a full summary of the COP16 talks after countries reach a deal.)

Watch, read, listen

‘DISTURBING’ PROGRESS: In Cali, the Guardian’s Patrick Greenfield reported on “alarm” raised by experts at a “disturbing” lack of progress at COP16.

AFRICAN ADAPTATION: For African Arguments, two policy experts called for the COP29 climate summit to adopt a clear adaptation goal amid growing climate impacts in Africa.
STOCKTAKE: For BBC Radio 4, environmental journalist Roger Harrabin examined whether the US election of 2000 was “the year we lost climate”.

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.
