UNEP Environmental Data Explorer
The UNEP Environmental Data Explorer (what was the GEO Data Portal until June 2012) is the authoritative source for data sets used by the UNEP and its partners in the  Global Environment Outlook (GEO) report and other integrated environment assessments. Its online database holds more than 500 different variables, as national, subregional, regional and global statistics or as geospatial data sets (maps), covering themes like Freshwater, Population, Forests, Emissions, Climate, Disasters, Health and GDP. One can display them on-the-fly as maps, graphs, data tables or download the data in different formats.
