System of Environmental-Economic Accounting (SEEA) is a framework to compile statistics linking environmental statistics to economic statistics. SEEA is described as a satellite system to the United Nations System of National Accounts (SNA). This means that the definitions, guidelines and practical approaches of the SNA are applied to the SEEA. This system enables environmental statistics to be compared to economic statistics as the system boundaries are the same after some processing of the input statistics. By analysing statistics on the economy and the environment at the same time it is possible to show different patterns of sustainability for production and consumption. It can also show the economic consequences of maintaining a certain environmental standard.
