The System of Environmental-Economic Accounting 2012 - Applications and Extensions (SEEA Applications and Extensions) provides potential compilers and users of SEEA based environmental-economic accounts with material to show how this information can be used in decision-making, policy review and formulation, analysis and research. The SEEA Applications and Extensions provides a bridge between compilers and analysts allowing each to recognise both the potential uses and the related measurement considerations. It is a companion document to the SEEA Central Framework which was adopted as the initial international statistical standard for environmental - economic accounting in 2012.
