This paper provides an overview of the main trends in development finance with biodiversity-related objectives for the period 2011 to 2020, using available OECD statistical data, from various sources. The resources covered are: Official Development Assistance and non-concessional development finance, both bilateral and multilateral, from members of the OECD Development Assistance Committee (DAC) as well as non-members, including South-South and Triangular Co-operation; private finance mobilised by public interventions; and private philanthropy. In addition, this paper assesses financing provided by bilateral DAC members that are Parties to the UN Convention on Biological Diversity, looking at how they fared collectively against the Aichi Target 20 on development finance. The paper was prepared by the DAC ENVIRONET Secretariat, with inputs from the OECD Environment Directorate, and with guidance from a group of DAC members.
