Global Environment Outlook
Global Environment Outlook (GEO) is a series of reports that review the state and direction of the global environment, issued periodically by the United Nations Environment Program (UNEP). The GEO project is a response to the environmental reporting requirements of UN Agenda 21 and to a UNEP Governing Council decision of May 1995.
It was introduced after the 1992 Rio Conference on Environment and Development, at a time when government and stakeholders lacked a common information basis to develop a broad and comprehensive view of environmental issues.
The reports published to date are as the following:
Six GEO reports have been published to date: GEO-1 in 1997, GEO-2000 (i.e., GEO-2) in 1999, GEO-3 in 2002, GEO-4 in 2007, GEO-5 in 2012, and GEO-6 in 2019.
