A rushed final text in Baku strains trust between nations, as inadequate climate finance commitments leave vulnerable countries calling for justice

The hasty imposition of a deal at the UN climate conference, Cop29, in Azerbaijan, over the objections of poorer nations has fractured global trust and undermined recent progress. This was supposed to be the “finance Cop” when two dozen industrialised countries – including the US, Europe and Canada – promised to pay developing nations for the damage caused by their rise. Instead, developing nations – led by a group including India, Nigeria and Bolivia – say this weekend’s agreement for $300bn a year in 2035 is too little, too late. Worse, rich-world governments will be able to escape their obligations by being able to rely on cash from private companies and international lenders.

Independent experts say the developing world, excluding China, would need $1.3tn a year by 2035 to fund its green transition and keep temperature rises in line with the Paris agreement. The climate finance target, pushed through by the Azerbaijani chair, is described by poor nations as a death sentence for those already drowning under rising seas and facing devastating costs.
