The carbon account records stocks and flows of carbon in and between various reservoirs: biosphere (stocks in vegetation, water etc.), atmosphere (as CO2,CH4 etc.), geosphere (oil, coal etc.) and the economy (e.g. warehousing, imports and exports of coal). These stocks and flows can be used to compile a carbon account for a certain area. Like the biodiversity account, the carbon account is a separate thematic account, related to both the condition of ecosystems and the provision of ecosystem services.
