OECD development finance statistics capture an integrated picture of both bilateral and multilateral climate-related external development finance flows.

Climate-related development finance at the activity level:
The substantial increase in ODA with climate objectives – USD 44 billion in 2020 – reflects the rise in activities marked for adaptation only (from 10% to 14% of total ODA) and, to a minor extent, that of activities pursuing both mitigation and adaptation (7% to 8%). Mitigation-only activities remain stable (11%). As a result, adaptation-related ODA surpassed mitigation-related ODA for the first time.
Which sectors does bilateral climate-related ODA target?
Support for mitigation dominates in sectors with more potential for greenhouse gas emission abatement, such as transport and energy. Support for adaptation focuses more on those closely linked to the ecosystem, such as agriculture, forestry and fishing, or water supply and sanitation. Some sectors, such as general environment protection, are mostly supported by activities that pursue both.

Methodology
The OECD measures and monitors bilateral development finance targeting climate change objectives using two Rio markers:
Climate Change Mitigation - introduced in 1998. Reporting on ODA flows has been mandatory since 2006. Reporting on non-export credit OOF flows was introduced in 2010 on a voluntary basis.
Climate Change Adaptation - introduced in 2010, with reporting mandatory for ODA flows. Reporting on non-export credit OOF flows was introduced in 2010 on a voluntary basis.
