A fair share of climate finance: apportioning responsibility for the $100 billion climate finance goal
In Copenhagen in 2009, developed countries committed to jointly mobilise $100 billion a year by 2020 to address the needs of developing countries.
Wealthy countries missed this target in 2020 and look set to fall short again in 2021. Their failure to meet their climate finance commitments threatens to poison the forthcoming climate negotiations in Glasgow.
The climate accords rely on pledging and do not include any formulae for determining how responsibility for this target should be apportioned among developed countries. While this may have been a necessary political compromise in 2009, the lack of guidance makes it difficult to hold individual countries to account.
This working paper suggests three metrics to assess each developed country’s fair share of the climate finance goal: gross national income, cumulative carbon dioxide emissions and population. While imperfect, these metrics offer an indicative range to begin holding individual governments to account.
