New climate plans from more than 60 countries would cut global emissions by only 10% by 2035, about one-sixth of what’s needed to limit heating to 1.5C, a UN analysis shows.
UN climate chief Simon Stiell said progress was being made but warned of an urgent “need for more speed.” Major emitters including China and the EU have yet to finalise updated targets, while the US plan submitted under Joe Biden may not be upheld if Donald Trump withdraws from the Paris deal again.
The findings come ahead of Cop30 in Brazil, where leaders must address the growing gap between pledges and action. Experts say weak commitments from big polluters threaten global progress, with analysts urging stronger political will and faster delivery.
