This partnership is founded on the belief that data is the foundation for our understanding of the environment. Data provides a basis for assessing change across time, for analyzing the environmental challenges facing a particular area, and for determining the need for local, national and global action on the environment. However, data on the environment is often not comparable across locations and time, it is not compiled at a frequency that can support regular analysis and it is often difficult to access and use environmental data.
UN Environment and Google are partnering with the European Union Joint Research Center (JRC), the European Space Agency (ESA), the United States National Aeronautics and Space Administration (NASA) and the Group on Earth Observations (GEO) to provide free and open data on the environment in a way that is policy-friendly, so that citizens and governments can easily assess what is actually happening to the world's natural resources, starting with data on water extent as a priority environmental issue.
The United Nations Environment Programme (UN Environment) is the leading global environmental authority that sets the global environmental agenda, promotes the coherent implementation of the environmental dimension of sustainable development within the United Nations system, and serves as an authoritative advocate for the global environment.
