Environmental challenges have no borders and are too vast and too complicated for any single entity to address alone. UNEP partnerships with governments, environmental conventions, the scientific community, academia, private sector, civil society, international and regional organizations, global funds, the financial sector, philanthropies, individuals, UN entities and others help to deliver on the 2030 Agenda and the Sustainable Development Goals. Being a key partner of major environmental funds such as the Green Climate Fund (GCF), the Global Environment Facility (GEF), the Adaptation Fund (AF) and the Multilateral Fund (Montreal Protocol) UNEP enables countries to access financing and programming through them and other bilateral or multilateral public sources.
