‘Travesty of justice’: Cop29’s controversial deal
Madeleine Finlay hears from the Guardian’s environment editor, Damian Carrington, about the controversial climate finance deal that brought Cop29 negotiations to a close in the early hours on Sunday morning in Baku, Azerbaijan. Developing countries asked rich countries to provide them with $1.3tn a year to help them decarbonise their economies and cope with the effects of the climate crisis. But the final deal set a pledge of just $300bn annually, with $1.3tn only a target. Damian tells Madeleine how negotiations unfolded, and what we can expect from next year’s conference in Brazil.
