Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Climate chaos
DEADLY DISASTER: Devastating landslides have killed 167 people, with another 191 missing, in the Wayanad district in Kerala, India, reported the Indian Express. Prime minister Narendra Modi announced compensation of 200,000 Indian rupees (about $2,390) per person for the families of the deceased and 50,000 rupees (about $600) for those injured, the newspaper said.
CLIMATE FACTOR: The Hindustan Times noted that scientists have attributed the landslide to a “combination of climate change, excessive mining and loss of forest cover in the region”. Opposition leader Rahul Gandhi called for “mapping of landslide-prone areas and…an action plan to address the growing frequency of natural calamities in the ecologically fragile region”, reported the Independent.
FLASH FLOODS: More than 10,000 people displaced from conflict in Sudan’s Sennar state – alongside other refugee and host communities – have been severely impacted by extreme rainfall and flash floods in Kassala state, reported the UN Office for the Coordination of Humanitarian Affairs. At least five people have reportedly died, including a child, the report said. Other affected areas include Aj Jazirah, East Darfur and North Kordofan, according to ReliefWeb.
Sizzling Olympics
HEATWAVE GAMES: A rapid attribution analysis found that the “heat dome” striking the Paris Olympics and the “scorching temperatures” across western Europe and North Africa this week would have been “impossible” without the “fossil-fuelled climate crisis”, reported the Guardian. Scientists at the World Weather Attribution (WWA) group said human-caused global warming made the heatwave “2.5C to 3.3C hotter”. Leading climate scientist Dr Friederike Otto told reporters: “Climate change crashed the Olympics on Tuesday.”.
KEEPING COOL: BBC Sport said that organisers used hoses and misters to keep spectators cool at the Paris Olympics. In Marseille, where temperatures reached around 40C, athletes taking part in sailing events wore “ice vests” to try to counteract the heat, the broadcaster added.
TRIATHLON TIMEOUT: The men’s triathlon was postponed due to “unsafe pollution levels” in the Seine following heavy rainfall in the French capital, reported Sky Sports. The organisers blamed the postponement on climate change, with Aurélie Merle – the Paris 2024 director of sports – saying: “We are living in the 21st century where, unfortunately, there are far more meteorological events…which are beyond the control of the organisers.”
Around the world
- UK RENEWABLES: UK energy secretary Ed Miliband announced an increase to this year’s renewable energy auction budget to a record £1.56bn on Wednesday, reported BBC News.
- HARRIS APPROVED: Inside Climate News reported that Kamala Harris has clinched an endorsement from the Green New Deal Network – “a key coalition of progressive, youth-led and environmental justice-focused climate advocates” – which had previously held back its endorsement for president Joe Biden.
- FUND FIGHT: The EU is gearing up to pressure wealthier “emerging” economies, such as China, to pay into the climate fund at the COP29 climate summit, reported Politico. Currently, only countries categorised as “industrialised” under the 1992 UN climate treaty contribute climate finance under the Paris Agreement.
- OFFSETS BLOW: A review by the Science Based Targets initiative, a global auditor of corporate climate targets, has concluded that “various types of carbon credits are ineffective”, reported Bloomberg.
- COP16 SAFE: Reuters reported that “Colombian rebel group” Estado Mayor Central has withdrawn its threat, issued earlier this month, to disrupt the UN biodiversity summit COP16 taking place in October in the Colombian city Cali – as a “gesture of [their] will for peace”.
7,500,000
The methane emissions, in tonnes, from US oil and gas facilities – four times more than the estimates of regulators – which is equivalent to the annual energy needs of over half of US homes, reported the Financial Times.
Latest climate research
- A new research paper published in Nature Communications found that current policies put the world on a trajectory with a 45% chance of crossing tipping points in the Earth system by 2300, even if the global average temperature is brought back to 1.5C later on. Carbon Brief had all the details.
- The UK would gain “benefits” worth £164bn if it meets its 2033-2037 climate targets, said a study published in the Journal of Environmental Studies and Sciences covered by Carbon Brief.
- A new study in BioScience proposed a way to preserve the Earth’s “increasingly threatened” biodiversity on the moon through the creation of a lunar biorepository – a storage facility for biosamples – by developing a system using cryopreserved fish fins.

Deep-sea mining mapped

Carbon Brief published an in-depth explainer this week into what the emerging field of deep-sea mining means for climate change and biodiversity. The map, taken from the article, shows the current designated areas for deep-sea mining exploration, with each of the orange dots representing exploration contracts within four significant zones: Clarion-Clipperton Zone, Mid-Atlantic Ridge, Indian Ocean and Northwest Pacific Ocean. The colours indicate the types of deep-sea mineral resources targeted. Polymetallic nodules – formed of iron and manganese silicates and hydroxides – are in green. Polymetallic sulphides – with copper, zinc, lead, iron, silver and gold – are in blue. Cobalt-rich ferromanganese crusts – with high cobalt concentration and other rare elements – are in pink.

Tuvalu’s plan to be first ‘digital nation’
This week, Carbon Brief reports on how the Pacific island nation of Tuvalu is aiming to become the world’s first digital nation in response to climate change.
Tuvalu, a small nation comprising a group of nine islands in the South Pacific, is among the most vulnerable to climate change. The Guardian has reported that rising sea levels are an “existential threat” for island nations such as Tuvalu. In 2023, a NASA report indicated that sea levels in Tuvalu had risen nearly six inches (15cm) over the past 30 years.
Estimates show that, by 2050, more than half of the land area of Funafuti – the capital – could be flooded.
According to the Pacific Regional Environment Programme, less than 0.03% of global greenhouse gas emissions come from the Pacific Island region.
Yet, as Tuvaluan minister Simon Kofe noted in his address to the COP26 climate summit in Glasgow in 2021 while standing knee-deep in the sea, “Tuvalu is sinking”. Invoking the issue of climate justice, he said:
“In Tuvalu, we are living with the realities of climate change and sea level rise.”
Rising sea levels in Tuvalu are already “leaching soil, killing crops and spoiling drinking water”. A recent National Geographic article also underscored food security challenges, with cultivating staple crops such as taro, breadfruit and coconut becoming difficult due to seawater infiltration. Flooding has become routine, with intense tides sweeping over the sole airstrip and homes monthly.
Facing the possibility of becoming entirely submerged and uninhabitable, Tuvalu has developed the Future Now project and aims to become the world’s “first digital nation”, existing in the “metaverse”, a virtual reality project started by Facebook.
Digital replicas
Addressing delegates in his COP27 speech, Kofe, standing in front of a digital replica of Te Afualiku, the first island in Tuvalu to be digitised, said:
“As our land disappears, we have no choice but to become the world’s first digital nation.”
This serves as the model for the digital recreation of all Tuvalu’s islands and its landscape, including “the coral atolls and reefs, the lagoon, the porous sandy soil, the palm trees and what is left of the pandanus, breadfruit and taro” – before it potentially physically disappears, he said.
The plan includes using satellite imagery, photographs and drone footage capable of capturing details as fine as grains of sand on the beach and the direction of ocean currents.
Tuvalu has completed a thorough three-dimensional LIDAR scan of all 124 islands and islets and began enhancing its national communications network – laying the groundwork for its digital nation, Kofe told delegates at COP28.
It has also started exploring a digital ID system using blockchain technology to connect the Tuvaluan diaspora, enabling their participation from across the world, the project developers said. This digital platform will allow Tuvaluans to connect, explore their heritage and engage in new business opportunities across various sectors, they added.
Additionally, the project has begun the development of a digital archive of Tuvaluan culture, with contributions from citizens who were encouraged to preserve their most valued personal items to create an evolving record of their heritage.
‘Digital sovereignty’
If Tuvalu’s physical land becomes uninhabitable, it also prompts a discussion of statehood and sovereignty. Under current international law, a defined physical territory is a prerequisite for statehood.
In order to become the first digital nation, Tuvalu – recognising the evolving notion of state sovereignty – redefined statehood through a constitutional amendment in 2022 to say:
“The State of Tuvalu within its historical, cultural and legal framework shall remain in perpetuity in the future, notwithstanding the impacts of climate change or other causes resulting in loss to the physical territory of Tuvalu.”
Tuvalu’s permanent and digital sovereignty is now recognised by 25 countries, with the Pacific Island Forum also redefining its territory, maintaining that its statehood would continue regardless of the impacts of climate change.

Australia blows PIF climate opportunity as Pacific leaders urged to band together
KOROR, PALAU, Friday 4 September 2026 – At the closing of the 55th Pacific Islands Forum Leaders Meeting in Palau overnight, Greenpeace Australia Pacific called out Australia for promising climate action while expanding fossil fuel production, and is urging Pacific leaders to unite ahead of the Pacific Pre-COP.
The meeting was rocked by the UN’s 1.5°C overshoot report a day before Australia approved the extension of one of the country’s largest coal mines.
Speaking from Palau, Shiva Gounden, Head of Pacific at Greenpeace Australia Pacific, said:
“Against the backdrop of the 1.5°C UNEP report, this Forum was a vital opportunity for Pacific leadership to shine by firmly calling out fossil fuels and banding together for our shared Pacific future. While the final communique reaffirmed the need to accelerate the transition away from fossil fuels, Pacific leaders missed the opportunity to hold the Australian government accountable for their continued approval of new coal and gas projects.
“At Pacific Pre-COP in Nadi, we are calling for Pacific priorities to be centred and respected by Australia and our global partners: they must support the ambition of a Fossil Fuel Free Pacific, ensure access to adequate climate finance and lead a global push to hold the line on 1.5°C as a matter of Pacific survival.
“Leaders fell short at the Pacific Islands Forum, and Pacific Pre-COP is the opportunity to match the ambition with urgency, and set the vaka on course toward a peaceful, just Pacific future.”
Speaking from Palau, Dr Simon Bradshaw, COP31 Lead and climate expert at Greenpeace Australia Pacific, said:
“The Pacific Islands Forum was an opportunity for Prime Minister Albanese to show real commitment to climate action and to its Pacific partnership. Instead, this week the Australian Government ‘celebrated’ the first extraction of polluting gas from the Beetaloo Basin and approved an extension of one of Australia’s largest coal mines. All amidst a still unfolding flood crisis in Nepal-Tibet and the devastating news that the world will blow through 1.5°C of warming — a survival line for Pacific communities.
“These are not the actions of a government aspiring to be a global climate leader and effective middle power in turbulent times, they are the actions of a government still beholden to the fossil fuel industry. Australia, get it together.
“As we head towards the Pacific Pre-COP, our Prime Minister and Government must remember the responsibility we have taken on. We must hold the line on returning warming to 1.5°C as our legal and moral obligation. This means doing everything possible to accelerate the global transition away from fossil fuels, starting at home.”

More support needed to power Africa’s food systems with renewables, experts say
As efforts to expand energy access across Africa grow, experts and policymakers have called this week for greater coordination and investment to power food production with renewables, arguing the sector has been treated separately from energy policy and therefore faces barriers in going green.
Hailemariam Desalegn, former prime minister of Ethiopia, said energy is critical across the food value chain – from irrigation and processing to cold storage and transport – and should therefore be considered a key pillar of strengthening food systems for the future.
“Energy is not separate from the nutrition challenge. Irrigation needs energy. Cold storage, transport, processing, as well as markets – all need reliable energy,” Desalegn told a panel at the 20th session of the Africa Food Systems Forum in Kigali. He said investments in sustainable energy systems could help reduce post-harvest losses and make nutritious food more accessible and affordable.
Africa loses up to 30% of its food before it reaches markets annually, largely due to poor roads, weak storage and inadequate cold chains, according to a 2025 report by the Alliance for a Green Revolution in Africa (AGRA).
Akinyi Walender, Africa director at development charity Practical Action, said poor energy supply in rural communities – where much of Africa’s food is produced – is also limiting productivity. Across the continent, about 600 million people currently live without access to electricity.
“The lack of energy access goes well beyond the inconvenience of not having lighting at home,” Walender said, adding that renewable energy has the potential to power local economies. “When people can access this sort of energy, it can raise rural incomes, improve food security, improve resilience, empower women and stimulate enterprise while creating jobs,” she added.
Breaking down silos
Unlocking the potential of energy across food systems requires greater coordination, Walender argued, pointing to institutional fragmentation and isolated pilot projects as major barriers.
“Organisations working on agriculture and energy often operate according to different modalities and the interdependence between agricultural and energy markets is often overlooked,” Walender said, adding that finance institutions also tend to work in silos.

Dana Rysankova, global lead for energy access at the World Bank, told a separate event at the forum that the bank is working to break down those barriers through its newly established Productive Use of Energy (PUE) Centre of Excellence based in Nairobi, which has a mandate to foster collaboration and help develop and design programmes across different sectors.
Can giant batteries unlock Africa’s green industrial future?
In June, the World Bank Group and the African Development Bank Group said that over 50 million people had been connected to electricity across 40 African countries under their Mission 300 initiative, which aims to provide electricity access to 300 million Africans by 2030.
Rysankova said the programme has shown that energy access is just the foundation for linking with other sectors to deliver real economic transformation by boosting productivity and local incomes.
Mission 300 also aims to electrify schools and healthcare services, as well as bringing power to farmers so that they can use it for irrigation, cold storage and other agricultural activities, she added.
Bridging the finance and infrastructure gap
Experts said bigger investments are needed in infrastructure and finance to turn energy access into increased productivity and economic value.
AGRA’s 2026 foresight report, launched at the forum, puts the annual agrifood financing gap at $180 billion, while estimating that closing Africa’s yearly $67 billion-$108 billion shortfall in infrastructure finance could halve post-harvest losses and increase farmer incomes by up to 40%.
However, the cost of transitioning to clean energy is still a major barrier for farmers and agribusinesses.


Atinuke Lebile, CEO of Nigerian food processing company Cato Foods, told Climate Home News she would like to switch to using renewables but has been held back by the upfront cost of setting up the systems the firm needs.
Rwandan farmer Gezel also said she would like to invest in a solar irrigation pump, but “it is so expensive”.
Practical Action’s Walender said the challenge is no longer whether solutions exist, but how financial support can reach the communities and businesses where it could have the greatest impact.
“Customers are dispersed and have low incomes. Markets are fragmented, and there are high upfront costs for much energy equipment,” Walender said, adding that financial institutions also often perceive agriculture as a high-risk sector.
Egypt seeks to unlock renewable potential to power regional clean energy hub
For food processing, the business case for using cleaner energy more efficiently is particularly strong, said Vivian Maduekeh of Partners in Food Solutions, which has worked with more than 2,000 companies across Africa.
Maduekeh said food processing firms account for between 42 and 70% of energy use across food systems, while energy represents 15-22% of their total production costs. African food businesses also use roughly twice as much energy per kilogramme of product as their global competitors, putting them at a competitive disadvantage.
The problems they face in shifting to clean energy are “risk, perception of risk and the cost”, she explained, adding that financial mechanisms are needed to help businesses overcome those issues.
Maduekeh encouraged policymakers to consider measures like tax rebates on imported equipment and spending more on research and development to bring down the cost of productive-use technologies.
Making a range of affordable equipment available – such as smaller irrigation pumps – could also help make the transition more accessible, she said. The evidence in favour “is very clear”, she added. “We just need to package it and communicate it to the priorities of investors.”

UK’s budget juggling trick with rainforest loan for bus-fare cap needs transparency
Andy Burnham, the UK’s latest prime minister, has suggested reducing the amount the British government gives as climate finance grants and providing some of its climate finance through loans instead, in a move it anticipates will save £400 million.
The government plans to use the savings to fund a cap on bus fares in the UK, triggering accusations from the development sector that Burnham’s proposal “throws Global South countries under the bus”. One likely destination for these new loans is the Tropical Forest Forever Facility (TFFF).
Will new UK PM’s green measures at home cause climate finance pain overseas?
The TFFF is a new initiative designed to provide payments to countries that protect their rainforests by raising money from governments and private investors, channeling that money into riskier and therefore higher return assets, and using the returns it earns to fund forest protection. But there is a catch.
The UK has committed to provide around £6 billion in climate finance funded through aid (or official development assistance, ODA) over the next three years. If switching from grants to a loan to the TFFF reduces government spending, it will likely reduce the amount that counts as ODA as well.
In other words, the government can make the £400 million saving, or meet its £6 billion aid budget-funded climate finance commitment, but it probably cannot do both. The UK cannot have its cake and eat it.
How will it score as ODA?
Whether any loan to the TFFF scores as ODA depends on the OECD’s Development Assistance Committee (DAC) which is currently deliberating on this topic.
A plain reading of the DAC’s current reporting rules suggests that the TFFF would count as a multilateral organisation: the independent investment arm, the Tropical Forest Investment Fund, would ultimately be a global, official entity (with sovereign governments appointing the board and being sole equity holders), which pools capital from sponsor governments. This would mean that to count as ODA, any loan to it would have to charge less than 5% interest.
Tropical forest protection fund at risk after UK stalls on pledge
The current concept note suggests a return for sponsor capital equivalent to US borrowing costs of a similar duration: currently around 5.2%, which would make any such loans ineligible. The UK could choose to charge less, but if the UK charges less than it borrows (also above 5%), the difference will add to the deficit in future years. And ODA accounting is not binary: if the UK charges just under 5%, only a small fraction of the loan would count.
At the same time, the risk profile of TFFF is not the same as your average multilateral, and there is speculation that the DAC could allow higher interest loans to TFFF to partially count (by changing the ‘discount rate’ used to measure how concessional the loan is). The TFFF’s own modelling suggests that the risk of the UK losing money on the loan would be fairly limited: roughly a 1% chance of some capital impairment in the riskiest scenario. But some analysts doubt the accuracy of this model and view the risk as much greater.


Would it really save money?
If the risk really is higher, then it might justify counting more ODA on a loan to the TFFF, but it also undermines the arguments that this would create savings for the government. Loans generally don’t count towards the deficit because they create an asset. But that only works if the loan is expected to be fully repaid. If there is a material risk of losing money, then at least some of the transaction will also count towards the deficit.
One possibility is that the loan will be ‘partitioned’ into a financial asset (the part which is expected to be repaid and wouldn’t count towards the deficit) and a ‘capital transfer’ (the part not expected to be repaid). The greater the risk, the larger that second component, and the bigger the impact on the deficit.
This would be the ODA and public accounting rules working as intended. ODA is a measure of ‘donor effort’, usually taken to mean fiscal impact. If it counts as ODA, it should have an impact on the deficit. And the fiscal treatment itself is governed by numerous international accounting standards, a key purpose of which is preventing politically motivated obfuscation of how governments spend their money. If it costs money, there should be an impact on the deficit even if it is a loan. If it doesn’t, it shouldn’t count as ODA (even if there have been exceptions in the past).
UK halves Green Climate Fund contribution, as it spends more on security
Base funding on need, not accounting
We still know too little about the details to be sure how a loan to the TFFF (or a more exotic transaction) would count towards either ODA or the UK’s headline measures of debt and deficit. The key parameter for each is risk: the lower risk, the more likely it is that the transaction will save money, but the greater the chance that the government would have to spend more ODA elsewhere to meet its climate finance target.
If the UK believes in the TFFF business model and wants to preserve tropical forests, then it should invest. But this decision should not be driven by optimistic accounting tricks. The government cannot expect to reduce the real value of climate finance to partner countries by giving less in grant money, without this having an impact on commitments to spend that money.
