The Brundtland Commission, formerly the World Commission on Environment and Development, was a sub-organization of the United Nations (UN) that aimed to unite countries in pursuit of sustainable development. It was founded in 1983 when Javier Pérez de Cuéllar, the Secretary-General of the United Nations, appointed Gro Harlem Brundtland, former Prime Minister of Norway, as chairperson of the commission. Brundtland was chosen due to her strong background in the sciences and public health.
