In 1992, the Global Environment Facility (GEF) was established to support developing countries in the implementation of environmental conventions. Since 1991, the GEF has provided $13.5 billion in grants and leveraged $65 billion in co-financing for 3,900 projects in more than 165 developing countries. For 23 years, developed and developing countries alike have provided these funds to support activities related to biodiversity, climate change, international waters, land degradation, and chemicals and waste in the context of development projects and programs.
