Addressing the impacts of climate change requires raising and steering significant financial resources. Since 1992 and the adoption of the United Nations Framework Convention on Climate Change, developed countries have been obliged to contribute climate finance, in recognition of their disproportionate historic responsibility for climate change. In 2009, they agreed to deliver $100-billion per year by 2020 - a target extended through 2025.

'The $100-billion goal' was met in 2022, but the collective nature of these commitments allows some countries to sidestep their responsibilities, while others deliver an outsized contribution. In our latest 'fair share' report, we found the trend had continued: many countries delivered two and three times their 'fair share', while others met barely a third of theirs. Yet, many countries who failed to meet their 'fair share' still saw significant increases in their provision of climate finance compared to the previous year's data.
