Climate finance from developed to developing countries: 2013-17 public flows


This report was prepared by the OECD, in response to a request by developed countries to help them better understand public climate finance trends. The accounting and methodological framework is identical to the one used by the OECD in 2015 to produce estimates of total climate finance for the years 2013-14.

This new data series for 2013-2017 shows that public climate finance from developed to developing countries increased from USD 37.9 billion in 2013 to USD 54.5 billion in 2017. Including climate-related officially-supported export credits brings this figure from USD 39.5 billion in 2013 to USD 56.7 billion in 2017. For both aggregates, this corresponds to a 44% increase. The year-on-year rise has been steady aside from a small dip in 2015.

The 2017 figure is broadly consistent with a linear pathway to the level of public climate finance from developed countries that the OECD has previously projected would be reached in 2020, i.e. USD 66.8 billion in 2020, excluding export credits.

Previously-estimated mobilised private climate finance for 2013-14 are provided in this report for completeness. It is foreseen that estimates of mobilised private finance for 2015-17 will be produced in 2019.
