Discuss in brief the following: Brundtland Commission.

The Brundtland Commission, formally the World Commission on Environment and Development (WCED), known by the name of its Chairman Gro Harlem Brundtland, was convened by the United Nations in 1983. The Commission was created to address growing concern "about the accelerating deterioration of the human environment and natural resources and the consequences of that deterioration for economic and social development." In establishing the Commission, the UN General Assembly recognized that environmental problems were global in nature and determined that it was in the common interest of all nations to establish policies for sustainable development. The Report of the Brundtland Commission, Our Common Future, published in 1987, deals with sustainable development and the change of policies needed for achieving that. The definition of this term in the report is quite well known and often cited: "Sustainable development is development that meets the needs of the present without compromising the ability of future generations to meet their own needs."
