The Global Environment Outlook (GEO) global assessments provide an integrated analysis (e.g. social, economic, environmental) of major trends that have shaped the environment. These reports provide world leaders with policy options to take immediate action to address environmental issues by turning environmental discussions into practice. Using the integrated environmental assessment (IEA) methodology, UN Environment has produced five GEO reports and a set of regional GEOs thus far, which have analyzed environmental state and trends at the global and regional scales, described plausible outlooks for various time frames and formulated policy options.
