In matters relating to the environment, the United Nations Conference on Environment and Development, held in June 1992 in Rio de Janeiro, produced an “Earth Charter,” or declaration of basic principles for the conduct of nations and peoples with respect to environment and development; agreements on special legal measures, including conventions on climate change and biodiversity, and principles for a framework agreement on forests; and an agenda for action, establishing the environmental work program agreed by the international community for the period beyond 1992 and into the 21th century.
