Because of the primary character of biomass ecosystem production and the comprehensive coverage of carbon/biomass accounts, they play a central role in ecosystem capital accounts. Carbon/ biomass is the primary service expected from the ecosystem, under the constraint of sustainable supply of water (for human use and the ecosystem itself) as well as sustainability of all the regulating (water regulation, assimilation of residuals, habitat regulation, pollination) and socio-cultural services which are produced. Carbon/biomass use and ownership can also be detailed by economic sectors, which is done in another part of the SEEA, so-called the 'supply and use tables' and 'asset accounts'. Carbon/biomass can in that way be brought together with the SNA tables in money terms.
