Hit $100bn target or poor countries face climate disaster, the Gambia tells Cop26

West African nation's environment minister says richer countries must finally honour funding commitment made at Cop15 in 2009

Rich countries must hit their $100bn climate finance target in the last week of Cop26 or it will be catastrophic for the poorest nations suffering the most from the climate crisis, the Gambian environment minister has warned.

In an interview with the Guardian as he prepared to leave for Glasgow, Lamin B Dibba urged developed countries to finally honour the annual funding commitment that was made 12 years ago at the Copenhagen climate summit (Cop15) - but which has never been achieved.
