OECD development finance statistics capture an integrated picture of both bilateral and multilateral climate-related external development finance flows.
In 2021, 27.6% of bilateral allocable ODA from DAC members pursued climate objectives: a decrease from the 2020 peak, back to the levels recorded between 2015 and 2019.
Activities with a principal climate objective remained stable between 2020 and 2021, at USD 14 billion (in 2020 prices) in both years. Activities with climate change as a significant objective totalled over USD 23 billion in 2021, a considerable drop from 2020 (USD 30 billion) but it is in line with the values recorded in 2015-19.
The 2020 peak value owes mostly to a few large activities reported that year by a few DAC members.
Bilateral climate-related ODA by region
In 2020-21 the share of climate-related commitments to African countries (26%) was considerably less than for other regions, where climate-related ODA always surpassed one-third of the total commitments:
40% in Latin America and the Caribbean, 39% in Asia and 37% in Oceania.

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.
