NEW – Q&A: What does Trump’s repeal of US ‘endangerment finding’ mean for climate action? | @ayeshatandon.carbonbrief.org @ceciliakeating.carbonbrief.org @daisydunne.carbonbrief.org @giulianaviglione.bsky.social @joshgabbatiss.bsky.social @mollylempriere.carbonbrief.org Read here: buff.ly/11Rtah7

We tend to think of batteries as the ones in our phones. But the real shift is happening at grid scale. Utility-scale “mega batteries” now have hundreds of millions of times the capacity of a smartphone battery. Costs are down ~40% since 2024, and capacity in 2024 was 12x higher than in 2020.

NEW ANALYSIS: China's CO2 has now been 'flat or falling' for 21 months * Down in 2025 * Still below Mar 2024 * Clean energy wave a key factor If this is China's peak (TBC) it's the climate story of the century so far… www.carbonbrief.org/...

Not easy to ignore what Trump is doing to the US right now in terms of attacking climate polices and climate science. But this below is the biggest and most consequential climate story in the world right now. Period.

The second set of CfD results this week makes AR7 the largest auction yet, with 14.7GW of renewable capacity secured Solar and onshore wind were both contracted for less than half the cost of new gas power, And AR7a incl. the first solar NSIP and the largest onshore windfarm in England in a decade

Nearly 5GW of solar contracted in UK govt auction. Biggest ever in capacity and confirms solar as the cheapest power in Britain. More solar = lower bills.

NEW: UK's "AR7" renewable auction was the biggest ever – more than 50% larger than 2024's record AR7 = enough electricity to offset 3/4 of UK LNG imports Labour's AR6+AR7, combined, contracted more GW than all other rounds put together More: www.carbonbrief.org/...

How much will it cost the UK to reach an 87% cut in greenhouse gas emissions by 2040? In a new letter, @thecccuk.bsky.social confirms about £4bn a year (£26bn a year of costs minus £22bn a year of savings). www.theccc.org.uk/wp-content/u... 87% by 2040 is a stepping stone to net zero by 2050

Africa recorded its fastest solar growth on record in 2025, driven by a surge in utility-scale projects

NEW | UK wind generation reached a new record in Jan 2026, producing 10.6 TWh 🇬🇧🍃 Prev. record of 10.4 TWh was set in December of 2023. Higher wind meant gas generation in Jan-26 dropped 17% compared to Jan-25, despite higher electricity demand. This saved an estimated £164 million in January.

This week, the UK govt published its Warm Homes Plan. Lost to history now, but 35 years ago (?!) the then UK govt launched a £10m campaign "declaring war on wasted heating and lighting around the home". The campaign included an advertising campaign: "Global warming. We have been warned."

It's a myth that Net Zero will cost us. What will *really* cost us is climate heating. Heatwaves cost lives, floods and storms cost millions in property damage, wildfires and droughts cost our environment. Cost of climate inaction >> cost of action. Acting now = an investment in the future.

Truly wild that the Sun, Daily Mail, Daily Express & Daily Telegraph all covered false claims that net-zero will "cost" £7.6bn – or even £9tn – which assumes we could have free gas, free petrol, free petrol cars & free gas power plants if we scrapped net-zero More here: bsky.app/profile/drsi...

Here's the other side of the story you won't read in today's headlines about the cost of meeting net zero targets. The reality is the IEA report is deeply flawed and based on some pretty blatant cherry-picking of clean tech costs. www.businessgreen.com/news/4524063...

🧵A political/media guide to the "truth" about net-zero 1) Add up costs to install & run a net-zero energy system 2) Pretend fossil-fuelled alternatives wld be free 3) Do say "eco zealots are bankrupting us" 4) Don't say "free cars if we scrap net-zero" cos it sounds ridiculous 5) That's it! 1/10

We took a look at Trump's move to pull the US out of the bedrock climate treaty, the UNFCCC, as well as the IPCC. CB talked to experts about whether he can legally, unilaterally withdraw the country from international treaties and whether the US could rejoin in the future

Carbon Brief has published its 20,000-word summary of everything that happened at #COP30, incl: 🇧🇷 Brazil's leadership and around the COP 🤝 The ‘Global mutirão’ text 💰 A new tripling adaptation finance goal 💥 The JTWP's Belem Action Mechanism ⌨️ And so much more www.carbonbrief.org/cop30-key-ou...

🆕 UNILATERAL TRADE MEASURES #COP30 After fighting for inclusion on COP agendas in Dubai, Baku and Belém, climate-related trade measures are on the verge of having their big moment on the cover of COP30 climate talks.

Shots fired #COP30 plenary PANAMA: "Mr. President, Panama is extremely disappointed. We were promised a transparent process. That is not what we're seeing. I raise my flag and you ignore it. I raise a point of order, and you ignore it. I sustain it, and it can be ignored."

COP30's key text, the global mutirão, just adopted here in Belém 🇧🇷

New Global Mutirão text retains a "call for efforts" to triple adaptation finance, but pushes the deadline for this to 2035 - five years later than the previous draft and what the LDCs and other developing parties have called for Full text: unfccc.int/sites/defaul...

COP30 DeBriefed | ‘Mutirão’ text latest; ‘Roadmaps’ explained; COP finish times plotted ✍️ @daisydunne.carbonbrief.org @joshgabbatiss.bsky.social @mollylempriere.carbonbrief.org Read here ➡️ buff.ly/4tDXWhm

New global goal on adaptation text! It both "adopts the Belém Adaptation Indicators" and establishes a two-year "Belém–Addis"programme for policy alignment, in what seems to be a compromise The one outstanding para points to the mutirão text, which "calls for efforts to triple adaptation finance"

As part of a wave of new COP30 texts dropped this morning, there is a new, clean version of the just transition work programme. Crucially, this "decides" to develop a just transition mechanism - the Belem Action Mechanism (BAM) - proposed originally by civil society and taken up by G77+China

COP30 ADAPTATION FINANCE: It's worth recalling the previous goal, adopted at COP26 Specifically, this "urge[d]" developed countries to "at least" double adaptation finance from 2019-2025 This is same wording as Opt 3 in latest COP30 draft, altho that also adds an annual dialogue on progress

Big fire in the Blue zone at COP30, people ran away shouting ‘fire’ and the building was evacuated, Hearing reports that it is now contained, (All CB staff were safely evacuated)
