Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Broken records
FIRES: Wildfires have burned through more than 1m hectares of land across the EU, making 2025 the worst year on record, the Guardian reported. Blazes in the EU have burned four times as much land this year as the average over the past two decades, according to data from the European Forest Fire Information System, the outlet said. Meanwhile, the UK has “almost certainly” faced its hottest summer on record, according to provisional Met Office data covered by BBC News.
FLOODS: At least 34 people have been killed as heavy rainfall across India and Pakistan continued to cause flash floods and landslides in Indian-controlled Kashmir, the Associated Press reported. Continuing extreme rainfall in China has caused more than $2bn in damages since July, noted Reuters. Typhoon Kajiki has killed at least eight people in Vietnam and Thailand, with more flash floods and mudslides expected, Channel News Asia reported.

POWER SHOCK: Shares in the Danish wind-power developer Ørsted dropped to a record low after the Trump administration ordered the firm to stop work on a near-complete project, the Financial Times reported. The $1.5bn Revolution Wind project is four-fifths complete and was due to power 350,000 homes in Rhode Island and Connecticut, the newspaper said.
‘WINDFARM WASTE’: In the UK, the energy regulator Ofgem announced that energy bills will rise by 2% for millions of households in October, with the Times reporting that part of the increase is due to the rising cost of “paying wind farms to switch themselves off”. The news sparked a wave of critical editorials and comment pieces in right-leaning and climate-sceptic UK newspapers. A Carbon Brief factcheck previously explained how gas prices, rather than “balancing costs” associated with wind farms, are the largest driver of high electricity prices in the UK.
Around the world
- FORESTS FOREVER: At a summit in Colombia, Brazil won the backing of other Amazon nations for its $125bn “Tropical Forests Forever Facility”, a fund first launched at COP28 in 2023, Bloomberg reported.
- CHINA CAP: China’s cabinet announced that the country will “tighten its carbon trading market by introducing absolute emissions caps in some industries for the first time starting by 2027”, Reuters said.
- RECORD RENEWABLES: Global renewables investment increased by 10% in the first half of the year, when compared to last year, to a record $386bn, according to new data from BloombergNEF covered by BusinessGreen.
- BANKING BREAK: The Net-Zero Banking Alliance has “paused” its activities “after losing top European and Wall Street members amid Trump’s ongoing crusade against climate change”, reported the Financial Times.
- STAFF SUSPENDED: The US Federal Emergency Management Agency (Fema) has suspended more than 20 members of staff who signed an open letter warning that Trump’s cuts to the body could risk a “national catastrophe” on the scale of Hurricane Katrina, according to BBC News.

Captured

Carbon Brief published an in-depth factcheck debunking 16 of the most commonly heard false and misleading myths about solar power. One such claim is that solar power poses “a serious threat to agriculture and food security” by taking up land. The chart above, adapted from the factcheck, puts such a claim in perspective using the land-use of golf courses as a comparison.
Spotlight
How to reform the UN’s climate COPs
This week, Carbon Brief highlights a short extract from a new autobiography written by the late Peter Betts, who was the UK and EU lead negotiator at various COPs, including 2015’s pivotal COP21 in Paris. Betts, who died of brain cancer in October 2023, used his book to lay out his views on how to reform COPs – a topic Carbon Brief recently asked a range of experts about, too.
Of course, the UNFCCC and COP process has its shortcomings. For example, I would be the first to acknowledge that progress on finance, adaptation and loss and damage has been too slow. But I would argue that it would not have happened at all without the central global discussion afforded by the COPs, at which vulnerable countries always have a strong voice.
The alternative to COPs – often put forward by big and powerful countries – is to do everything within the G20, perhaps complemented by plurilateral cooperation between big states. No one would be more pleased to see the end of the COP process than big oil and gas interests in the US who sought to undermine COPs throughout my decade or more in negotiations.
My experience was that excluding the vulnerable countries led to lower-ambition outcomes which the US and emerging economies were comfortable with. The vast bulk of vulnerable countries would be horrified to lose the COPs, since it guarantees them a voice.
Overall, then, I believe that the case for keeping a global forum, where all have a seat at the table and, therefore, the most vulnerable have a voice, is overwhelming, and this is the UNFCCC. It is an indispensable political moment every year to rally the forces of ambition for climate change (and, to paraphrase Voltaire, if we didn’t have it, we would need to invent it). There are, however, two improvements that could be made to the way COPs operate.
1: The second stocktake
Formal stocktakes occur every five years, at a point two years before the next five-yearly ambition cycles of the COPs (such as Paris and Glasgow). But there is almost no focus by the media or NGOs on the announcements of NDCs [nationally determined contributions], especially those of “developing countries”, despite the importance of NDCs’ impact on climate goals.
In the run-up to the five-yearly stocktakes there should be a moment, perhaps a third of the way through the year, where we can see where we stand, individually and collectively, following the NDCs that have been announced. If some countries’ proposals are weak, those countries should be pressured to do more; if some have not submitted a proposal at all, then that should be highlighted.
It seems unlikely that the big economies would agree a formal process change, as when I have suggested such a second stocktake “moment” to various partners they have expressed concerns that it would be controversial. However, civil society should look to create this moment outside the formal process with analysis and media-friendly events which would provide an opportunity to assess (and put pressure on) relative, proposed contributions.

2: Annex membership
Second, we should review membership of the annexes to the convention, which set out who is “developed” and who is a “developing” country. We need a step change in support for emerging economies to help them make the transition to low carbon, which is increasingly affordable and will bring them other benefits. This means much more finance from Annex II countries, complemented by finance from China (the world’s biggest sovereign investor) and from Gulf states, who have grown rich on selling fossil fuels.
Sadly, however, I doubt whether it will be possible to negotiate changes to membership of the annexes, even though that was required by the convention to happen by 1998. But could countries such as China and the Gulf states not voluntarily step into Annex I and/or even Annex II?
Non-Annex I countries now constitute nearly two-thirds of global emissions and are likely to be a far higher proportion of emissions growth. So, if we want to limit climate change, it is these emissions we need above all to target. Of course, we must complement this by quicker action by Annex I countries, perhaps alongside negative emissions, and we must provide much more serious help to some non-Annex I countries.

Framing the climate science debate as a binary battle isn’t just wrong – it’s dangerous
Lidy Nacpil is the coordinator of Asian Peoples’ Movement on Debt and Development (APMDD).
Recent reporting on international climate negotiations has highlighted a sharpening divide within civil society and multilateral diplomacy. A troubling, simplistic narrative has taken root: that the UN climate process is witnessing a binary struggle between defenders of science and those attacking it.
This framing is not only inaccurate; it is dangerous. Characterising a substantive methodological and political debate in these terms misdiagnoses the stakes and stirs conflict instead of clarity.
No one disputes that climate action must rest on science. Science tells us what has led us to the climate crisis – the accumulation of historical emissions – and how much carbon budget remains if we are to keep temperature rise below 1.5C. It tells us how much global emissions must drop, and how fast. Science is also essential in assessing each country’s historical contribution to the accumulation of greenhouse gases in the atmosphere.
Responsibility, however, must also be based on capacity. For those who generated the largest share of historical emissions, that capacity includes the enormous wealth and economic power accumulated through the same fossil-fuel-intensive development that generated those emissions.
As science comes under attack at UN talks, climate movement splits over how to respond
While principles that should guide human action aren’t scientific questions – they are matters of values – applying them to real-world problems requires scientific grounding. Equity recognises the scientifically established reality of differentiated responsibilities among countries and within societies. Putting equity into practice demands scientific rigour.
Scrutiny of IPCC models
Today, critics are scrutinising the assumptions and frameworks behind the Intergovernmental Panel on Climate Change’s Integrated Assessment Models (IAMs), used to project future scenarios and map global mitigation pathways. These concerns centre squarely on equity and justice.
The economic, technological and policy assumptions used in IAM scenarios are normative choices rather than scientifically prescribed or neutral facts. These include choices about discount rates, economic growth, energy demand, technology costs, carbon prices, land availability and the regional location of mitigation. Many IAM scenarios reproduce existing global inequalities rather than transform them. Questions about transparency, representativeness and diversity in the scientific process are deeply urgent.
Most IAM scenarios are built primarily around global cost-effectiveness – directing emissions reductions to places where mitigation is modelled as cheapest rather than allocating effort according to historical responsibility, capacity and development needs.
The resulting pathways allow developed countries to retain disproportionately high levels of energy and fossil-fuel consumption while requiring developing countries to undertake substantial mitigation and carbon removal, including land-based measures that threaten food security and local development.
Northern models often assume uniform access to cheap financing. In reality, Global South economies face far higher capital costs, driving up the price tag of rapid infrastructure shifts.
Constraints on development space
Scenario constraints also limit the development space poorer nations need without guaranteeing adequate climate finance. When models treat profoundly unequal starting points as uniform baselines, policy pathways lock in global inequality under the banner of scientific objectivity.
Pointing out these structural flaws isn’t rejecting science. It is essential scientific scrutiny aimed at producing stronger, fairer, and more actionable results.
Science ‘under attack’ from fossil fuel interests at UN climate talks
The fight is not about whether we want to keep temperature rise below 1.5C, but about how we get there. A pathway can be technically compatible with 1.5C or 2C while still being deeply unequal in who gets to consume energy, who must reduce emissions, and whose development is constrained. Temperature compatibility alone does not make a pathway fair.
Critiquing IAM scenarios from an equity perspective is neither an attack on the Intergovernmental Panel on Climate Change (IPCC) nor an attack on science. Rigorously examining IPCC reports – their substance, assumptions, and processes – is an acknowledgement of the IPCC’s importance and entirely consistent with scientific method.
Tensions over AR7 timing
There is a separate but related tension over the cycle and timeline of the IPCC’s Seventh Assessment Report (AR7). Some governments and civil society voices advocate completing its Working Group reports in time to feed directly into the UN’s Second Global Stocktake in 2028.
The motivation makes sense: policymakers need timely science. But several developing-country negotiators and researchers have warned that meeting that deadline could severely disadvantage the Global South.
Funding gap threatens next round of IPCC climate science reports, chair warns
Global North authors and institutions remain disproportionately represented in the research underlying IAM assessments. Developing-country researchers often work with fewer institutional resources, smaller research budgets, and less administrative support. Accelerated publishing and assessment schedules can further limit their ability to generate, submit, and peer-review research in time for inclusion.
The AR7 timeline concerns boil down to inclusivity, representation, and equity. Requiring the IPCC to meet tight political calendars without ensuring meaningful support and participation for developing-country researchers risks reproducing the very inequalities being challenged.
Cooperation requires equity
Political interests are indeed at work in UNFCCC negotiations and must be surfaced. Bad-faith actors seek to evade fossil-fuel phase-outs or shirk climate-finance obligations. Many developed country parties are guilty of both, including those who style themselves as “Friends of Science.”
We must not lump legitimate scientific critiques raised by several Global South researchers and many civil society organisations concerning representation, economic assumptions and fair-share accounting together with obstructionism. Doing so risks misrepresenting and delegitimising critical scientific work and Global South equity and justice perspectives.
The climate movement is strongest when it aligns rigorous science with global equity and justice. Achieving the Paris Agreement’s goals requires robust science that fully integrates the experiences, economic realities and academic contributions of the Global South. Effective climate action also requires international cooperation, and without equity, such cooperation cannot be sustained. We do not have to choose between science and equity. We need both.

DR Congo’s power-hungry mining sector drives record solar surge
More than 300,000 solar panels and 120 battery containers are helping to power Africa’s largest copper mine with continuous clean energy in the Democratic Republic of the Congo, as miners turn to solar as an alternative to expensive diesel and energy imports.
The project at the Kamoa Copper mine in the south of the DRC, which became operational last month, is one of the largest solar and battery facilities generating baseload power on the continent.
The clean electricity is displacing millions of litres of polluting diesel and costs less than a fifth of the price of generator power per kilowatt hour, the mining company said.
The project is part of a massive solar deployment across the continent. Recent data from global energy think-tank Ember found record solar capacity of 17 GW will be installed in Africa this year – a 45% rise from 2025.
Installed by CrossBoundary Energy, a developer of distributed renewable energy systems, the solar-battery facility at the DRC mine is “proof of concept” that solar and battery systems can provide the reliable power at scale needed by remote industrial operations, Annebel Oosthuizen, managing director at Kamoa Copper, told Climate Home News in an interview.
“There’s always been this perception in the DRC that solar isn’t ideal because it is raining half of the year. But it’s perfectly ideal. We are seeing a lot of interest from other mines that are still depending on generators and power imports,” she said.
Mining drives solar and battery surge
Like Kamoa Copper, a growing number of miners in the DRC are looking to solar power to compensate for the country’s chronic energy deficit at a lower cost as global diesel prices hit record highs amid ongoing attacks on oil infrastructure in the Middle East.
As a result, the mining sector has become a key driver of the country’s growing clean energy demand and one of the biggest importers of large-scale solar equipment.
Ember found the DRC is set to install a record 1.7 gigawatts (GW) of solar panels this year – a 544% increase compared to 2025 and the equivalent of adding more than 60% of the country’s entire 2023 grid capacity.
The deployment of combined solar and battery storage solutions to deliver stable energy supplies to mines has also caused battery imports to surge. In dollar terms, the DRC’s imports of batteries from China far exceeded that of solar in the year to June 2026, according to Ember.
A crippling power deficit
The DRC holds significant energy resources and some of the world’s largest reserves of the minerals required to manufacture clean energy technologies. It is the world’s largest producer of cobalt, which is needed to make batteries, and Africa’s top producer of copper – a metal sought after for its electrical conductivity which is pivotal to the world’s electrification efforts.
Yet just 22.5% of the DRC’s population had access to electricity in 2024 – one of the lowest rates in the world, according to the World Bank. And as mining expands and more of the minerals extracted are being processed in the country, unreliable power supply has become a major constraint for the sector, which contributed to more than a quarter of the country’s GDP in 2024, excluding oil and gas.
The country has enormous hydropower potential, with the hydroelectric potential of the Congo River estimated at around 100 GW. But only a fraction is being harnessed.
Still, virtually all of the DRC’s grid-connected electricity is generated by hydropower by the state-owned utility, Société Nationale d’Électricité (SNEL).
The electricity then has to be transported more than 1,500 kilometres to reach the mining belt in the south – a challenge made more difficult by ageing grid infrastructure and limited transmission capability. SNEL did not respond to a request for comment.
“It is estimated that there’s around a 1 GW energy deficit for the DRC mining sector,” said Matt Tilleard, CEO of CrossBoundary Energy, which owns the solar and battery equipment at the Kamoa Copper mine and provides the power as a service.
“The interest in solar from the mining industry is not theoretical – it is already translating into large-scale solar and battery procurement for mining operations in the region,” he added.
Solar displaces gas, saves energy costs
The facility installed by CrossBoundary is part of a plan by Kamoa Copper to supply more of the electricity it needs with solar energy and batteries as its operations expand, a faster solution than relying on harder-to-build hydropower projects.
“Our processing capacity has increased drastically over the last couple of years. We’ve constructed the largest copper smelter in Africa and that is so power-intensive,” said managing director Oosthuizen.
A joint venture between Canadian firm Ivanhoe Mines, Chinese company Zijin Mining Group and the DRC government, the mine needs 235 megawatts (MW) of power, which is expected to nearly double to 450 MW in the next five years.
Kamoa Copper currently receives 100 MW from state utility SNEL – “and the rest we have to find a solution for”, said Oosthuizen.

Another 30 MW solar and battery baseload facility is expected to come into operation this month, enabling around 25% of the mine’s power needs to be generated by solar energy. An additional 60 MW of continuous solar power will be added by the end of 2027, and the company is exploring options for more solar capacity and two hydropower projects.
The operational 30 MW of clean electricity provided by CrossBoundary Energy will power pumps that prevent 400 million litres of water from flooding the underground mine every day.
In August alone, the facility has reduced the mine’s diesel consumption by around four million litres, generating an estimated $11 million dollars in savings at current diesel prices, Oosthuizen said.
The mine still relies on generators to meet a 20-40 MW deficit and to power the trucks used in the mine, which Oosthuizen said would be difficult to electrify in the next five years because the technology isn’t yet ready to operate in the mine’s tough and wet conditions.

Avoiding a two-speed transition
To prevent a major imbalance between industrial players’ access to clean, reliable energy and the millions of Congolese who remain without power, the government requires private electricity producers to reserve at least 10% of their generated power for local communities living near rural production sites.
Delivering this, combined with rural electrification, mini-grid development and national grid expansion, is critical to prevent a two-speed energy transition that leaves people behind, said Catherine Mukobo, head of ACERD, the Congolese Association for Renewable and Decentralised Energies.
“Without implementing these policies, the DRC could get in a situation where mines have access to abundant modern energy while a large part of the population remains without electricity,” she said.

Commencement of NSW Forestry assessment a ‘chance to fix a broken system’ and deliver urgent forest protection
SYDNEY, Friday 18 September 2026 — In response to the Federal and NSW government’s announcement to commence an assessment of NSW forestry under the new national nature laws, Adele Chasson, Nature Policy Lead at Greenpeace Australia Pacific said:
“This is the Federal Government’s chance to fix a broken system that has enabled the destruction of NSW’s precious forests for far too long.
“Native forest logging continues to smash threatened species habitat. In NSW, it is pushing unique wildlife like koalas, greater gliders and glossy black cockatoos towards extinction. The state-owned logging agency has a disastrous record of environmental damage and breaches.
“The Regional Forest Agreement (RFA) system has failed, allowing the industrial logging of special forests for decades across Australia with no oversight. Thankfully, the Federal Government has started the process to finally remove the logging industry’s exemption from national nature laws.
“It’s time for the Federal Government to deliver the protection that forests urgently need, and that Australians overwhelmingly want. The Government must ensure a thorough assessment of the devastating impacts of native forest logging in NSW, and establish strong environmental rules that states must follow.
“These forests have been cared for by First Nations people for tens of thousands of years. They are some of the most biodiverse on the planet, store carbon, clean our air and water. It’s critical we protect them.”
