Rich failing to help fund poor countries' climate fight, warns UN secretary general

Exclusive: Antonio Guterres says key promise of $100bn funding will be missed, damaging trust in Paris deal

Rich countries will miss a key promise they made to the poor world on the climate crisis by failing to provide the money necessary for them to cope with its effects, damaging the prospects for global action, the UN secretary general has said.

Developing countries were supposed to receive at least $100bn (75bn) in financial assistance from public and private sources this year and in future years to help them cut greenhouse gas emissions and deal with the ravages of extreme weather. The promise was one of the cornerstones of the 2015 Paris agreement and will be a key element of next year's Cop26 climate talks.
