The System of Environmental-Economic Accounting (SEEA) provides a framework for measuring the links between the environment and economy.
The SEEA consists of two parts. The SEEA Central Framework (SEEA CF) was adopted by the UN Statistical Commission as the first international standard for environmental-economic accounting in 2012. The Central Framework looks at individual environmental assets, such as water, forests and fisheries resources, and how they are extracted from the environment, used within the economy, and returned to the environment as air, water, and waste.
The SEEA Experimental Ecosystem Accounting (SEEA-EEA) complements the SEEA CF and provides a coherent accounting approach to the measurement of ecosystems. Ecosystem accounts enable the presentation of data and indicators of ecosystem extent, ecosystem condition, and ecosystem services in both physical and monetary terms in a spatially explicit way.
