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. 15.08.2014 15
