This working paper is part of WRI’s Climate Finance Series, which tackles a broad range of issues relevant to public donors, intermediaries, and recipients of climate finance. A subset of this series, including this working paper, examines how public funds can leverage private sector investment in climate-relevant projects to help meet developing countries’ significant investment needs. This paper maps climate-relevant investments of select multilateral agencies – the World Bank Group, the Global Environment Facility (GEF), and the Clean Technology Fund (CTF) – to identify trends in their investment practices. Subsequent working papers will map the activities of other public institutions. The aggregated findings will be synthesized into recommendations that inform the future public provision of climate finance with respect to leveraging private sector capital.
