The fund designed to finance climate « loss and damage » in vulnerable countries was adopted on Thursday 30 November 2023, on the first day of the 28th United Nations Climate Change Conference (COP28) in Dubai. The establishment of this fund is the practical expression of the main promise made at COP27 in Egypt, where the mechanism was approved in principle but not adopted. Nearly six countries have already announced their contributions to this fund, but we are still a long way from the 100 billion dollars expected by developing countries.
