New national climate plans from more than 60 countries would cut global carbon emissions by only 10% by 2035, about one-sixth of what’s needed to limit warming to 1.5C, the UN has warned.
UN climate chief Simon Stiell said countries must act faster: “We have a serious need for more speed.”
Major emitters including China and the EU have yet to submit updated targets, while the US plan under Joe Biden may be dropped if Donald Trump pulls out of the Paris agreement again.
The findings come ahead of Cop30 in Brazil next month, where leaders will seek to close the gap between promises and action. Analysts say weak pledges from top emitters risk derailing global climate goals.
