This is the third edition of the joint MDB Report on Climate Finance, and the information provided has been expanded to include a better sectoral breakdown, and split by public and private operations.
This report covers finance for mitigation, adaptation and projects with dual adaptation and mitigation benefits. As in previous years, the calculation of mitigation finance is based on a common list of activities at the intersection of what all MDBs consider mitigation. Adaptation finance is calculated using the joint MDB methodology based on a context- and location-specific approach. Data reported in both cases corresponds to the financing of those components and/or sub-components or elements/proportions of projects that provide mitigation and/or adaptation benefits (rather than the entire project cost).
