Accounting for ecosystem costs and benefits at different scales…
Global scale
National & regional government, European market
Action level, local scale

Simplified ecosystem accounts
Markets need accounts, regulations [= control]
Land ecosystems are spatially distributed => grid data [e.g. 1 km2]
Globally, change matters [degradation or improvement of ecosystem functioning and attached cost], not the value of the stock
Global multicriteria rating based on a small number of ecological potential [derived from ecosystem accounts]:
Landscape ecological potential [LEP]Landscape ecological potential [LEP] HANPPHANPP Biodiversity rarefactionBiodiversity rarefaction Exergy loss [river basins]Exergy loss [river basins] Dependance from external inputs [material/energy, footprint]Dependance from external inputs [material/energy, footprint]
losses/gains of “points of ecological potential” computation of restoration costs [needed for compensating losses // or accumulated by gains of points]
Rating can be detailed as necessary for the policy [national, regional] and action scales [local, business]
