The Group on Earth Observations (GEO) was established in 2005 as an intergovernmental mechanism for coordinating all existing and future Earth observations systems and implementing a “Global Earth Observation System of Systems” (GEOSS). It was launched in response to calls from the WSSD, the G8 and three ministerial Earth Observation Summits to improve existing Earth observation systems. GEO now boasts over 70 member countries and 45 participating organizations. It is constructing GEOSS on the basis of a 10-Year Implementation Plan that runs from 2005 to 2015. It is funded by voluntary contributions.

Earth observations form the building blocks of humanity’s efforts to understand and manage our highly stressed global environment. To improve the value of these observations, GEO is actively linking together existing and planned Earth observation systems – including satellites, ocean buoys and weather stations – to create a Global Earth Observation System of Systems (GEOSS). It is encouraging the development of new systems to eliminate gaps in coverage, promoting common technical standards so that outputs from different instruments can be combined into integrated data sets, and helping individuals and institutions gain the skills and capacities they need to use Earth observations more effectively. GEO is taking a cross-cutting approach to nine interconnected priorities of critical importance to the future of the human race. It aims to help us to protect ourselves better against natural and human-induced disasters, understand the environmental sources of health hazards, manage energy resources, respond to climate change and its impacts, safeguard freshwater resources, improve weather forecasts, manage ecosystems, promote sustainable agriculture and conserve biodiversity.
