Global environment outlook 3: past, present and future perspectives
Global Environment Outlook 3 (GEO-3) - the flagship report on the state of the global environment of the United Nations Environment Programme (UNEP) - comes 10 years after the Earth Summit held in Rio de Janeiro in 1992 and 30 years after the Stockholm Conference on the Human Environment in 1972. By tracking and analysing important environmental issues over the period 1972-2002, GEO-3 provides an integrated explanation of major trends that have shaped our environmental inheritance.
