This policy briefing notes that international support for climate change adaptation falls short of what is needed. Latest estimates indicate that only 16 per cent of international climate finance is currently dedicated to adaptation – a mere $4–6bn per year of which is public finance. While Governments in Paris came close, much remains to be done to agree quantified goals to ensure adaptation finance increases at anywhere close to the scale needed in future. If global cooperation on climate change is to be inclusive, durable and fair, it must leave no one behind. The adaptation finance gap must be addressed urgently with an agreement at COP22 in Morocco on a roadmap for the $100bn commitment – one that includes quantified goals for adaptation finance, and progress on accounting and governance of finance flows.
