CIF is one of the world’s largest multilateral funds helping low- and middle-income countries adapt to and mitigate climate change. Since 2008, it has been channeling funds from government donors and the private sector to support more than 360 projects in over 80 countries. Its launch emerged from recognition by world leaders that climate change and development are inextricably intertwined, and that climate-smart investment is needed at scale to deliver on the opportunities for green growth identified in the UN's Sustainable Development Goals (SDGs). Working in partnership with governments, the private sector, civil society, local communities, and six major multilateral development banks (MDBs), CIF provides highly competitive financing that reduces risk for investors, lowering barriers to piloting new technologies, scaling up proven solutions, opening up sustainable markets, and mobilizing private sector capital for climate action. Rallying stakeholders behind increasingly ambitious climate goals and complementary action, CIF draws in diverse partners who might otherwise be deterred from investing alone.
