On Saturday night, the world reached agreement at “Cop30”, the latest UN climate summit. Sort of. This conference in Belém, Brazil, was supposed to be the “implementation summit”, where climate action would finally catch up with climate promises. That didn’t happen.
Across two weeks marked by protests, an absent America, an ascendant China, and even a fire that briefly halted negotiations, the world again failed to agree on a fossil fuel phase out.
Simon Chin-Yee researches international climate politics and was at the talks in Belém. With his UCL colleagues Mark Maslin and Priti Parikh, he looks at five key takeaways from the summit, and where the world goes from here.
