Economy National Accounts System of National Accounts (SNA, 1993) European System of Accounts (ESA, 1995) Environment Environmental statistics System of Environmental and Economic Accounts (SEEA, 2003) Environmental accounting Environmental accounts
Satelite of the National Accounts Resident principle Attribution of pollutants to economic activities System of Environmental and Economic Accounts (SEEA) 2003 Summary of different types of accounts Methodology and best practices
Environmental accounts 1.Physical flow accounts 2.Environmental related transactions (environmental costs, environmental taxes) 3.Environmental asset accounts (forest, fishery, subsoil accounts) 4. Adjustment of SNA to account for the impact of the economy on the environment (DNI)
NAMEA Started in 1991 Started in emission and 2 extraction categories 11 emission and 2 extraction categories 8 themes 8 themes Greenhouse effect (CO 2 equivalents)Greenhouse effect (CO 2 equivalents) Ozone depletion (CFK11 equivalents)Ozone depletion (CFK11 equivalents) Acidification (Acification equivalents)Acidification (Acification equivalents) Eutrophication (Eutrophication equivalents)Eutrophication (Eutrophication equivalents) Waste (kg)Waste (kg) Waste water (inhabitant equivalents)Waste water (inhabitant equivalents) Change in natural resources (kg)Change in natural resources (kg) Fossil fuel use (PJ)Fossil fuel use (PJ) Environmental taxes, subsidies and costs Environmental taxes, subsidies and costs Annual Annual Consistent & internationally accepted Consistent & internationally accepted
