Clean-energy technologies drove more than a third of the growth in China’s economy in 2025, according to new analysis for Carbon Brief. Carbon Brief’s @leohickman.carbonbrief.org summarises the analysis in this video. Read the full analysis here: buff.ly/M7N4yjx

Have China’s emissions just peaked? China’s CO2 emissions fell in the final quarter of 2025, likely securing a decline for the full year as a whole, according to new analysis for Carbon Brief by @creacleanair.bsky.social Full analysis here: buff.ly/wC1nbXO

COP30 was the 11th longest on record

When will #COP30 wrap up? If recent years are anything to go by, negotiations could last well into next weekend (Baku finished at 5am Sunday morning, 36 hours behind schedule…)

Every COP logo since 1995 – which is your favourite?

The list of US food items that the UK says might now see retaliatory tariffs seriously makes you wonder what the HELL is going on with our global food system?! "edible flours and meals of whales, dolphin and porpoises"

Run don’t walk to see Kyoto at Soho place! Can’t express just how impressive this play was. (See: a very happy row of Carbon Brief journos and my “Telegraph” press pass)

“They don’t make statues of critics” Roger Egbert:

BREAKING: The Court of Appeal will conduct a hearing of 16 Just Stop Oil protestors, arising from four separate cases, including JSO leader Roger Hallam and Phoebe Plummer and Anna Holland who threw soup on glass protecting Van Gogh’s Sunflowers.

My heart goes out to the original Bluesky (aerial survey and height data services)

After tense #COP29 talks, parties agreed on a new climate finance goal... but many argued the USD 300 billion/year was an “insult” While parties took decisions on carbon markets, on many other issues they remained deadlocked ENB Summary ➡️ enb.iisd.org/baku-un-clim... #climatechange #climate

Japan is considering a new target of 60% emissions cuts by 2035, up from a previous target of 42% reductions, according to this report by Japan's public broadcaster NHK www3.nhk.or.jp/nhkworld/en/...

COP29 was the fourth longest on record, clocking in 35 and a half hours later than planned

COP29 has overtaken COP21 - where the Paris agreement was signed - as the fifth longest COP on record…

We've started! COP29 president Babayev says this plenary will gavel items "ready for adoption" And also urges parties to find consensus on topics still being debated, such as the finance goal, in "the coming hours"

#COP29 QUORUM CHECK At this point, it’s worth reviewing the UNFCCC rules of procedure: Two-thirds of Parties must be present for decisions to be made (130/195 parties to the Paris Agreement, or 132/198 for UNFCCC). 1/3

Already a day into overtime and things not looking great at #cop29

A public walkout like this is basically unheard of -- especially at this late stage of negotiations. Does not portend well for the last hours of #COP29

How's #cop29 going? On Twitter, Panama's negotiator Juan Carlos Monterey just posted that two big developing country groups, LDCs and AOSIS, have walked out of consultations…

If you want to nerd-out over #COP overrun statistics, @jjgoodman.bsky.social is your man.

Just in case you're wondering how long COP29 might continue to overrun, my colleague Joe has all the data and charts you need...

People have been loving Carbon Brief's webinars – so here's another one! If you want to understand the outcome of #COP29 (once it ends) tune in to my expert colleagues on Monday, who have been in attendance and will explain what went down and answer your questions ⬇️ us02web.zoom.us/webinar/regi...

The Earth Negotiations Bulletin provide the definitive summary of day to day COP (and the data for my COP closing chart)… Their predictions range from 18 to 43 hours overrun… (Best of luck to negotiators over the next few days!)

This is the difference between Twitter and Bluesky btw

Data in everything including time of overruns of COP climate talks

The @carbonbrief.org sweepstake on when #COP29 will end has now closed. We've had 200+ guesses submitted. On average, they put the final "gavel-down" moment in the small hours of Sunday morning: Mean: Sunday 00:23 Median: Sunday 01:34 Mode (nearest hour): Sunday 03:00-04:00

It's likely #COP29 will overrun. But by just how much is harder to say. Since COP1 in 1995, there's been a trend for longer and longer COPs – peaking at a whopping 44 hours overrun in Madrid in 2019. Last year's COP overran by a modest 23 hours, making it the shortest COP in 6 years.

Check out this awesome animation that my colleague @jjgoodman.bsky.social made for our new @carbonbrief.org analysis! More details on analysis here: www.carbonbrief.org/analysis-chi...

This is striking. UNEP emissions gap report said recently that China’s share of cumulative emissions was on a par with the EU. But CarbonBrief now saying China has overtaken EU.

NEW ANIMATION: China’s cumulative emissions have overtaken the EU for the first time… …but under future projections, China’s emissions may *never* eclipse the US (despite having just a fraction of the population) buff.ly/4hQ131z with @drsimevans.carbonbrief.org @vernerviisas.carbonbrief.org
