Developed countries agreed to deliver USD 30 billion in new and additional ‘fast-start finance’ (FSF) between 2010-2012 to developing countries, as a step towards mobilizing USD 100 billion per year from public and private sources by 2020. By the end of the FSF period, the self-reporting of developed country governments indicated that they had exceeded this goal. ODI, World Resources Institute (WRI) and Open Climate Network (OCN) have been working to understand where the money has gone, and what it has supported. This analysis can help to shed light on what has been achieved during the FSF period, and to draw lessons for international climate finance in the years ahead. You can view a compilation of this analysis on our new Fast Start Finance page.
