Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Shifting political players
EU LEADERSHIP: Ursula von der Leyen has secured another five years as president of the European Commission following a vote yesterday in which she won the backing of 401 MEPs – 40 more than needed, reported Bloomberg. In her reelection bid, von der Leyen committed to EU climate goals including the still-pending 90% emissions reduction by 2040 target and a new Clean Industrial Deal, Euractiv reported. However, the publication noted that her comments on nature protection were limited to “positive rhetoric” only.
PARIS PM: Elsewhere in Europe, veteran climate negotiator Laurence Tubiana has been proposed as the next French prime minister, with backing from the Socialist, Green and Communist parties in the current hung parliament, reported Climate Home News. Tubiana, who is currently CEO at the European Climate Foundation [which funds Carbon Brief], was one of the “architects” of the Paris Agreement in 2015, according to Bloomberg.
VANCE’S STANCE: In the US, Donald Trump’s newly selected running mate JD Vance has come under scrutiny for his climate scepticism. The Republican vice presidential candidate is “a staunch supporter of the oil and gas industry and an opponent of renewable energy”, according to the Independent, but has reportedly only held such views in recent years, a shift that coincides with his bid for Trump support. He also has investments in “green” technologies, reported E&E News, but the New York Times emphasised his public anti-climate sentiments and his sponsorship of green legislation repeals as a senator for Ohio.
AFRICAN COAL: In South Africa, a political ecologist wrote in the Conversation that the country’s newly appointed environment minister has shown support for continuing to use coal and said his government would not be “bullied” into transitioning away from fossil fuels too quickly. It comes as Agence France-Presse reported that the country’s president Cyril Ramaphosa has “reaffirmed the coal-dependent nation’s commitment to moving towards renewable energy, but insisted that communities and workers must not lose out”.
Labour must ‘make up lost ground’
KING’S SPEECH: The UK’s new Labour government has confirmed a legislative agenda with the environment “front and centre”, reported the Guardian. The king’s speech mentioned that the government will set up the publicly owned GB Energy to “own, manage and operate clean power projects” across the UK, reported BBC News. The company is set to be capitalised with an £8.3bn investment. Meanwhile, Politico reported that Labour is set to appoint a climate envoy, a role that has been empty for more than a year.
NEW ADVICE: The Climate Change Committee (CCC), which advises the UK government on its climate policies, released its annual progress report on Thursday, urging Labour to “make up lost ground” after a lack of sufficient action under the last Conservative government. Carbon Brief covered the recommendations in detail (more on this below). Elsewhere, the Times reported that Emma Pinchbeck, chief executive of the industry group Energy UK, has been appointed “preferred candidate” for the next chief executive of the CCC.
Around the world
- ‘HELLISHLY HOT’: A heatwave across southern Europe and the Balkans has led governments to issue severe weather warnings, said France 24, with temperatures rising above 40C.
- CHINA ‘THIRD PLENUM’: A communique from China’s highly influential “third plenum” meeting called for a “coordinated approach to carbon cutting, pollution reduction, green development and economic growth”, as well as for the country to “actively respond to climate change”, according to state news agency Xinhua.
- CARIBBEAN VULNERABILITY: In the aftermath of Hurricane Beryl, which killed at least a dozen people and destroyed infrastructure across the Caribbean, the Associated Press reported that officials are demanding more funding from “financial and development institutions” to rebuild and address climate change.
- PROTEST IN PERIL: Five UK climate activists from Just Stop Oil received record-length jail sentences of up to five years for a plan to block London’s M25 motorway, reported Reuters. Meanwhile, the right to peaceful protest in Australia is also “in peril”, the Guardian reported.
- GLOBAL FLOODS: Downpours and flooding have killed hundreds in South Asia, caused “emergency alerts” in China, left more than 50 people dead in Niger and caused damage in Toronto, Canada.
$8.4bn
The amount of debt eradicated through “debt-for-nature” swaps from 1987-2023.
$7.6tn
The total amount of debt service paid by low- and middle-income countries over the same timescale, illustrating how swap schemes are “far too small to have any impact”, experts told the Carbon Brief.
Latest climate research
- European “fire weather” – conditions favourable to the ignition and spread of wildfires – will become “more severe” due to climate change, showed a new study in Environmental Research Letters.
- Optimising the conversion of organic waste into biogas for energy has considerable decarbonisation potential in China, said new research in Nature Communications, which found that their proposed system could contribute 3.77% of the emissions reduction needed for the country’s 1.5C-aligned target.
- Nature-based solutions have “consistently proven to be a cost-effective approach” to address disaster risk, reported researchers in Science of the Total Environment.

Captured
UK emissions have been falling steadily for years, largely driven by the phaseout of coal and the growth of renewable power. However, only one-third of the reductions required to achieve the UK’s goal under the Paris Agreement of cutting emissions 68% by 2030 are covered by plans the CCC deems to be “credible”, according to its latest progress report. There is an even larger credibility gap for the sixth carbon budget for 2033-2037, with only a quarter of the cuts needed covered by “credible” policies. This is illustrated in the chart above, which shows the emissions cuts needed to reach net-zero (red), compared to cuts expected from policies that the CCC deems “credible”.
Spotlight
The climate impact of generative AI
Carbon Brief investigates the climate implications of the accelerating use of generative AI tools.
Google’s latest environmental report indicated that its total emissions have increased by almost 50% since 2019 and 13% year-on-year – a change it puts down to the growth of its data centres and rising emissions in its supply chain.
The report added that rolling out artificial intelligence (AI) services might make it “challenging” to cut emissions due to the “increasing energy demands from the greater intensity of AI compute”.
Since March, Google has been integrating its generative AI tool Gemini into search functions, matching the exponential uptick in day-to-day AI use through Chat-GPT, Microsoft Copilot and other such tools. (“Generative AI” is AI that is capable of generating text, images, videos or other data from scratch in response to a prompt.)
But there’s a catch: when a query is sent to a generative AI model (a process known as inference), it uses a lot more energy than a traditional search, creating an expectation that the energy demand of data centres will shoot up as a result.
Soaring energy demand
A recent study, still awaiting peer review, found that a multipurpose AI system could use up to 33 times more energy than computers running task-specific software and that generating two images with AI uses as much energy as charging a smartphone.
Dr Sasha Luccioni, AI and climate lead at AI company Hugging Face and lead author of the study, explained to Carbon Brief that multipurpose models “tend to be larger in size” and are trained for several different outputs, “which makes them more computationally-intensive”.
Training AI models before they are available for use also takes large amounts of energy. OpenAI’s GPT-3 required 1,287MWh during training, enough electricity to power 120 average US households for one year.
Direct energy consumption is not the only factor to consider. Felippa Amanta, a PhD researcher of digital services at the University of Oxford’s Environmental Change Institute, told Carbon Brief that “generative AI can have quite unpredictable indirect energy effects from how they’re being used by households”.
People are also using AI assistants for things they never needed it for before – a phenomenon Amanta explained as “induced demand”.
AI is changing our day-to-day behaviour, “from finding recipes, to writing emails, making CVs and the list goes on”, she said. It is this increase in user inference that can drive up data centre energy demands.
A report from the International Energy Agency (IEA), released today, said that the rise of AI was putting an increased focus on the energy use of data centres. (AI currently accounts for around 10% of data-centre electricity use.)
It said that electricity consumption from data centres as a whole accounted for a “limited” 1-1.3% share of global electricity demand in 2022. This could rise to between 1.5% and 3% by 2026, according to its projections. (By contrast, electric vehicles are expected to account for between less than 1.5% and 2% by 2026.)
The agency noted that expectations of future data centre energy demand growth were highly uncertain, depending on the uptake of AI services and the efficiency of the chips used to run them. (It noted that chipmaker Nvidia recently unveiled a new chip that was 25 times more energy efficient than previous models.)
As with any electricity-intensive technology, the climate impact of surging AI use will be determined by the extent to which renewables can meet the demand. In April, the Financial Times reported that fossil-fuel companies are hoping that surging energy demand from AI use will “usher in a golden era” for gas production.
Efficiency and regulation
On the flip side, AI has the potential to be a tool for climate action, chiefly by increasing energy efficiency. For example, AI could be used to improve the efficiency of power grids or daily commutes.
But as generative AI tools become integrated into our lives, there is a risk of a rebound effect, where the ease and ubiquity of AI solutions make us use services more, countering any efficiency savings, Amanta said.
Another issue facing the rapidly changing AI environment is a lack of transparency.
The climate impacts of AI models can potentially be mitigated by increasing their computational efficiency, powering data centres with clean energy, or using more task-specific models – but a lack of transparent data is slowing the development of legislation to regulate this shift, Dr Luccioni told Carbon Brief:
“The fact that we can’t get an accurate estimate of the energy usage or emissions of the many AI-enabled tools used by millions of people daily is problematic.”
Without understanding the scope of the issue, it is difficult to regulate energy intensity or add constraints on companies, she added. The IEA’s report also called for more reliable data.
Amanta pointed to examples of policies being proposed in the US and Singapore that recognise the environmental impacts of AI’s growth and aim to regulate their efficiency and sources of energy. The EU’s AI Act, which came into force in June, includes environmental considerations.

Vishal Prasad is director of Pacific Islands Students Fighting Climate Change.
When the International Court of Justice (ICJ) delivered its advisory opinion on climate change last year, it marked a turning point not just for the Pacific, but for international climate law.
The court was unambiguous: states have legal obligations to protect the environment from greenhouse gas emissions, and they face accountability when they fail. For those of us who carried this campaign from a classroom in Vanuatu to Europe and New York, it was a moment of profound validation.
World’s top court opens door to compensation from countries responsible for climate crisis
But we have always said that the advisory opinion was a tool, not an endpoint. The ICJ affirmed what many in the Pacific have been saying for some time. Now we have a legal blueprint, we must carry this momentum from the courtrooms to the negotiating rooms.
Potential to shape climate politics
The advisory opinion has already begun to reshape the climate landscape. At COP30 in Belém, we saw countries that had supported the campaign citing the opinion in their interventions, while those blocking progress were clearly concerned of its implications. Its potential to shape climate politics and policy is significant.
This year we have arrived at the mid-year climate negotiations in Bonn not only with the advisory opinion, but with a UN General Assembly resolution endorsing it. Despite a fierce campaign from the usual suspects, just eight countries, including the USA, Saudi Arabia, Russia and Iran voted against. That is a victory for multilateralism at a moment when multilateralism is under strain.
UN General Assembly backs “climate obligations” set by world’s top court
But we know that advisory opinions alone are not enough. Legal clarity will not automatically translate into reduced emissions, increased finance flows or stronger national climate plans. That translation requires political will in the negotiating rooms, both here in Bonn and all the way through Fiji and finally in Antalya this November.
What the Pacific needs from this negotiating year
The Pacific put significant political capital into the joint Australia-Pacific bid for COP31. It is fair to say that the compromise of Australia holding the role of president of negotiations while the COP is held and presided over by Türkiye is not what we imagined.
But we in the Pacific are used to looking for silver linings. Both Australia and Türkiye have acknowledged the important role the Pacific will have at COP31, through the appointment of Pacific champions and the hosting of a Pacific Pre-COP in Fiji with a leaders event in Tuvalu. These are genuine opportunities to bring the world to our shores and ensure that Pacific issues are front and centre going into the final negotiations.
But we are not naive. Envoy positions and meeting locations are just the architecture of goodwill. We need to see that goodwill converted into concrete negotiating outcomes and finance.
COP31 leaders unveil global targets, with spotlight on electrification
The Pacific helped put Australia’s climate minister Chris Bowen in this important position, so we expect to see Australia advocate not only for us, but to turn a mirror towards itself as one of the world’s biggest fossil fuel exporters.
At Bonn, and then in Antalya, we need ambition on mitigation that reflects the ICJ’s clarity on state obligations and the science. That means action on fossil fuels.
We need climate finance that is new, additional and accessible to the countries that need it most. In the Pacific we have already demonstrated what that looks like.
The Pacific Resilience Facility is the first climate finance facility designed, governed and managed by Pacific people, built specifically to reach the grassroots and community initiatives that larger funds routinely bypass. We need the international community to meet that ambition with contributions that reflect climate justice, starting with pledges to meet the $500-million capitalisation goal.
And we need the oceans – which are the lifeblood of the Pacific and a critical part of the global climate system – treated as a central element of the negotiations rather than a thematic aside.
Energy crisis driven by imported fossil fuels
The days of speaking about climate and fossil fuels purely as a moral issue are long gone. Pacific ministers recently adopted the Tassiriki Call for a Fossil Fuel Free Pacific, in the context of a deepening energy crisis that has triggered states of emergency in several Pacific nations. Our dependence on imported fossil fuels is both a climate and an economic vulnerability.
Conflict in the Middle East is pushing our region into an energy crisis. We are dependent on imported fossil fuels for 80% of our energy needs. My home country of Fiji could see an increased fuel bill of nearly three times our annual healthcare budget.
Comment: COP31 must persuade countries to make fossil fuel transition plans
We need the technical and financial support to transition to 100% renewable energy. Not only because it is what the world owes us for decades of carbon pollution that continue to render parts of our home uninhabitable, damaging ecosystems and culture. But because we must be part of that transition. Fossil fuels have proven to be the greatest source of damage to our climate, and with their volatility, to our sovereignty as well.
What next?
The demands have not changed. Greater action on mitigation, adaptation, finance, loss and damage: these remain the substance of what the Pacific requires from the international community. What has changed is the legal foundation beneath them.
The ICJ has affirmed that these are not requests. They are obligations. The task this year is to make the negotiations reflect that.

A 20-year record reveals an estuary tipping toward a saltier, more acidic state. These conditions threaten its hammerhead shark nursery and the aquifer that supplies Miami’s drinking water.
In the shadow of Miami’s skyline, in water churned daily by boats and jet skis, juvenile great hammerhead sharks—a critically endangered species—spend the first two years of their lives. A few miles from downtown, researchers recently pulled a 12-foot critically endangered sawfish from the same shallows. The species has been dying off in alarming numbers across South Florida’s waters since 2024, in an event scientists suspect was set in motion by record ocean heat.
The Railroad Commission of Texas shut down injection wells to control a leak in a church parking lot. But 1.5 million gallons of toxic wastewater still spilled to the surface.
