United Nations conference on Environment and Development that was held in 1992 at Rio de Janeiro is also known as
Earth Summit
The United Nations Conference on Environment and Development (UNCED), held at Rio de Janeiro, Brazil, in June 1992, is popularly known as the Earth Summit (also called the Rio Summit). It was one of the largest environmental gatherings in history and marked a turning point in linking environmental protection with economic development, giving rise to the modern concept of sustainable development.
The summit produced several landmark outcomes: Agenda 21, a comprehensive global action plan for sustainable development; the Rio Declaration on Environment and Development, laying out guiding principles; a statement of forest principles; and it opened for signature two major treaties — the United Nations Framework Convention on Climate Change (UNFCCC) and the Convention on Biological Diversity (CBD). Because of its planet-wide scope and focus, it earned the popular name Earth Summit.
