Reaching agreement in divisive political landscape shows ‘climate cooperation is alive and kicking’, says UN climate chief

The world is not winning the fight against the climate crisis but it is still in that fight, the UN climate chief has said in Belém, Brazil, after a bitterly contested Cop30 reached a deal.

Countries at Cop30 failed to bring the curtain down on the fossil fuel age amid opposition from some countries led by Saudi Arabia, and they underdelivered on a flagship hope – at a conference held in the Amazon – to chart an end to deforestation.

But in a fractious era of nationalism, war and distrust, the talks did not collapse as was feared. Multilateralism held – just.

“We knew this Cop would take place in stormy political waters,” said Simon Stiell, the UN’s climate chief, after a long and occasionally angry final plenary at the climate summit. “Denial, division and geopolitics has dealt international cooperation some heavy blows this year.”
