Gro Harlem Brundtland (born April 20, 1939) is a Norwegian politician, diplomat, and physician, and an international leader in sustainable development and public health. She is a former Prime Minister of Norway, and has served as the Director General of the World Health Organization. She now serves as a Special Envoy on Climate Change for the United Nations Secretary-General Ban Ki-moon.
She is most famous for chairing the World Commission on Environment and Development (WCED), widely referred to as the Brundtland Commission, developing the broad political concept of sustainable development in the course of extensive public hearings that were distinguished by their inclusiveness and published its report Our Common Future in April 1987. The Brundtland Commission provided the momentum for the 1992 Earth Summit/UNCED, that was headed by Maurice Strong, who had been a prominent member of the Brundtland Commission. The Brundtland Commission also provided momentum for Agenda 21.
