Data on multilateral public climate finance and private climate finance mobilised by multilateral agencies’ interventions presented in the series of OECD reports on “Climate Finance and the USD 100 billion goal” only considers the share of finance that is attributable to developed countries. Multilateral institutions are typically funded or capitalised by core contributions from both developed and developing countries. Institutions that operate with a financial business model use these contributions as a basis for raising additional finance from the capital markets.
A specific methodology is, therefore, needed to calculate, for each institution, the share of its outflows attributable to developed countries, with the remainder being attributable to developing countries. Such calculation considers the most recent and historical replenishment participations by individual countries, as well as, where applicable, the institutions’ capacity to raise funds from the capital markets. The resulting attribution shares can be found in Table B.1.
