The Green Climate Fund (GCF) is the world’s largest dedicated multilateral climate fund, established in 2010 under the United Nations Framework Convention on Climate Change. Headquartered in Songdo, South Korea, it was created to help developing countries respond to climate change by directing international finance toward projects that reduce greenhouse gas emissions and strengthen resilience to climate impacts. Its governance gives equal representation to developed and developing countries on its Board.

GCF financing supports climate action across energy, transport, cities, forests, agriculture, water and other vulnerable sectors. The fund works through accredited public and private institutions, combining grants with concessional loans, equity and guarantees to mobilize larger pools of investment. It places particular emphasis on countries and communities with high climate vulnerability, including least developed countries, small island developing states and African countries, while seeking to align investments with national climate priorities and accelerate a transition toward low-emission and climate-resilient development.
