Mottley Puts a Number on the Climate-Finance Gap at the UN

Vulnerable states need about US$490 billion a year by 2030, against roughly US$90 billion flowing now, Barbados's prime minister told the United Nations.

Barbados Prime Minister Mia Mottley put hard numbers on the climate-finance gap at the United Nations, telling the assembly that vulnerable states need about US$490 billion a year by 2030 against roughly US$90 billion flowing to them now.

The gap is the argument. A more than fivefold shortfall between what small and climate-exposed states need and what they receive is the case Mottley has carried from Bridgetown to every major forum, and the frame behind the Bridgetown Initiative on reforming development finance.

For the Caribbean the stakes are concrete. The same islands that contribute least to emissions carry the highest catastrophe exposure, and the finance to adapt is the difference between recovering from a storm and being set back a decade by one.

The figures are from Prime Minister Mottley's remarks at the United Nations on September 24, 2026.
