New national climate plans from over 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, a UN analysis warns.
UN climate chief Simon Stiell said countries must “accelerate action now,” as progress remains too slow. Major emitters such as China and the EU have yet to finalise their pledges, while the US target set under Joe Biden may be abandoned if Donald Trump withdraws from the Paris accord again.
The report comes ahead of Cop30 in Brazil next month, where leaders will face pressure to close the growing gap between promises and action. Experts say weak commitments from big polluters threaten global climate goals despite record net zero pledges worldwide.
