The United Nations Conference on Environment and Development (UNCED), was a major United Nations conference held in Rio de Janeiro from June 3rd to June 14th in 1992.
An important achievement of the summit was an agreement on the Climate Change Convention which in turn led to the Kyoto Protocol and the Paris Agreement. Another agreement was to "not to carry out any activities on the lands of indigenous peoples that would cause environmental degradation or that would be culturally inappropriate".
