The report developed by ODI to which this briefing refers - 'A fair share of climate finance? The adaptation edition' - looks at the climate finance provided in 2021 to evaluate each country’s progress against the $100 billion goal. In addition, we produce new evidence to evaluate each country’s adaptation finance provision against the aim of at least doubling adaptation finance from 2019 levels by 2025, which we set at $40 billion – double the $20 billion reported in 2019.
