The Global 500 Roll of Honour was an award given from 1987 to 2003 by the United Nations Environment Programme (UNEP). The award recognized the environmental achievements of individuals and organizations around the world. A successor system of UNEP awards called Champions of the Earth started in 2005.

The United Nations Environment Programme (UNEP) is responsible for coordinating responses to environmental issues within the United Nations system. It was established by Maurice Strong, its first director, after the United Nations Conference on the Human Environment in Stockholm in June 1972. Its mandate is to provide leadership, deliver science and develop solutions on a wide range of issues, including climate change, the management of marine and terrestrial ecosystems, and green economic development. The organization also develops international environmental agreements; publishes and promotes environmental science and helps national governments achieve environmental targets.
