UN says climate adaptation funding will cover less than a third of needs
A new UN Environment Programme report says developing countries need $305 billion a year by 2035 to prepare for climate impacts such as floods, heatwaves and droughts.
Rich countries provided at most about $32 billion for adaptation in 2024, and funding has been flat or falling since 2022.
At the 2025 COP30 climate talks, wealthy countries agreed to triple adaptation finance by 2035, to between $85 billion and $120 billion a year.
Even if that pledge is met, it would cover only 20-29% of the estimated need.
The shortfall leaves poorer countries with less money for measures such as flood protection, stronger infrastructure and early warning systems.
Least developed countries and small island states face especially high risks and received less adaptation support in 2024 than in 2022.
The funding gap will be a focus at COP31, scheduled for November 9 to 20 in Antalya, Türkiye.
The UN Environment Programme says developing countries will need $305 billion a year by 2035 to adapt to climate change, or about $420 billion when future inflation is included.
A pledge to triple rich countries’ adaptation finance by 2035 would provide $85 billion to $120 billion annually, covering only 20% to 29% of the estimated need.
Rich countries provided $28.2 billion to $31.7 billion in adaptation finance in 2024, about $1 billion more than the previous year.
The report says adaptation funding remains far below needs as climate impacts intensify.
The findings were published ahead of the COP31 climate talks in Antalya, Türkiye, scheduled for Nov. 9-20.
