The questions behind ecosystem accounting• Risks of unsustainable use of the living natural capital are ignored:
the negative impacts of over-harvesting, force-feeding with fertilisers, intoxication, introduction of species, fragmentation by roads, or sealing of soil by urban development have no direct monetary counterpart.
• The natural capital is not even amortised in accounting books of companies and in the national accounts – no allowance is made for maintaining ecosystems’ critical functions and services. The full cost of the domestic products is not covered in many cases by their price.
• This is as well the case of the price of imported products made from degraded ecosystems: their full cost is not covered by their price.
• Actual value for people of free ecosystem services is not accounted (the market tells: price is zero).

Aggregates: integrated indicators valid at multiple scalesThis is not only a scientific, technical or data issue but a governance issue
• Action scale: local communities, conservations agencies, companies, citizens – management, development, production, consumption, mitigation
• Government scale: regions, countries (Unions of…) – framing and
implementing policies, tradeoffs, monitoring
• Global scale: global market and global ecosystem (atmosphere, oceans, biodiversity, river catchments…) – common objectives, conventions, monitoring, global mitigation
• Some indicators are scale-specific, other indicators are valid at multiple scales: ecological potential, HANPP, virtual land, cost of maintenance and restoration of ecosystems
