Global Environment Outlook 4 (GEO-4): environment for development

The fourth report in the Global Environment Outlook (GEO) series from the United Nations Environment Programme (UNEP) provides a comprehensive, scientifically credible, policy-relevant and up-to-date assessment of, and outlook for, the state of the global environment. The GEO-4 is published 20 years after the World Commission on Environment and Development (the Brundtland Commission) produced its seminal report, Our Common Future. GEO-4, the latest in UNEP’s series of flagship reports on the state of the global environment, assesses the current state of global atmosphere, land, water and biodiversity, and describes what has changed in those two decades. It salutes the real progress made in tackling some of the world’s pressing environmental problems.
