· Disaggregated regional or local data about the environment, sometimes linked to a geographic information system. Questions often arise about the scale of environmental data; do they pertain to a village, a province, a watershed, or the whole country? Because the SNA is national, and most countries maintain their economic data at the national (rather than the regional or local) level, environmental accounts are primarily national accounts. For example, they might tell us how much energy was consumed nationwide, not how much was consumed in each village or province. Sometimes national figures are obtained by aggregating local data, though; for example, national data timber harvests might originate with.
