Almost two-thirds of climate fund for developing nations already pledged

OECD report showing extent of existing pledges towards $100bn target to help poorer countries tackle climate change, gives further hope for success in Paris

Rich countries and businesses have provided close to two-thirds of the financial assistance pledged to poorer nations as part of the global climate change negotiations, ahead of the Paris conference this December.

The finding by the Organisation for Economic Co-operation and Development (OECD) is a further clearing of the path to an agreement in Paris, as it helps countries to judge whether pledges made at previous meetings can be trusted.
