About the product
This publication is produced by the United Nations Environment Programme (UNEP), as part of “Global Environmental Outlook-5” (GEO -5) Series that is the United Nations’ most authoritative assessment of the state, trends and outlook of the global environment. Through data, graphics and satellite images, the report offers wide-ranging information on a number of key issues, including population, climate change, energy, resource efficiency, forests, food security and land use, and drinking water. The report points out that the lack of sufficient, solid data and monitoring systems to measure progress remains obstacles to achieving the environmental goals set by the international community. It also highlights the missing pieces in our knowledge about the state of the environment, calling for global efforts to collect scientifically-credible data for environmental monitoring.
