The United Nations Environment Programme (UNEP) is an agency of United Nations and coordinates its environmental activities, assisting developing countries in implementing environmentally sound policies and practices. UNEP has overall responsibility for environmental problems among United Nations agencies but talks on addressing global warming are overseen by the Bonn-based Secretariat of the United Nations Framework Convention on Climate Change. Its activities cover a wide range of issues regarding the atmosphere, marine and terrestrial ecosystems, environmental governance and green economy.
