Declaration of Rio (1992)

United Nations Environment Program

Seeking to build upon the Declaration on the Human Environment (1972), the United Nations Conference on Environment and Development issued the Declaration of Rio. The Declaration states that since humankind is primarily concerned with sustainable development, States are responsible for fulfilling the developmental and environmental needs of present and future generations. It calls for all States to cooperate in global partnership by assisting developing countries that are environmentally vulnerable. In addition, the Declaration calls for the implementation of effective environmental legislation that addresses the problems of environmental degradation, focusing not only on species and habitats but also ecosystems. It also declares that States shall respect international law by protecting the environment in times of armed conflict.
