Resource flow developments
For time series of traditional resource flows
official statistics are normally quite useful

Sustainability (natural production)
Comparison of net anual increment forest growth
with consumtion transfered in net annual
increment. (Yearly calculations are a bit
problematic because of data accuracy.)

Conclusions

• The Wood Resource Balance (WRB) is a tool to
  document an overview on all relevant sources and
  uses of a resource.
• Data availability of new sources and new uses is
  the biggest challenge in calculating a wood
  resource balance.
• Until better statistical documentation of theses
  markets time series can be derived on assumtions
  as long as they are openly documented.

Conclusions

• The Wood Resource Balance (WRB) can be uses as a
  monitoring system for sustainability of the
  natural reserves of a resource.
• Depending on the existence of end use studies and
  disposal statistics it is furthermore a tool for
  calculation carbon sequestration in woody biomass
  uses on the basis of empirical, actual data.
