(Reuters) - Developed nations may have achieved their overdue promise of $100 billion to help poorer countries cope with climate change in 2022, the OECD said on Thursday, an estimate that may muster some political goodwill on the eve of the COP28 climate summit.

 

In 2009, developed countries promised that from 2020 they would transfer $100 billion a year to poorer nations hit by worsening climate change-fuelled disasters. Rich countries had previously signalled the target would not be met until 2023.
