The aim of the project was to provide methods and tools that will, for the first time, integrate Sustainability Impact Assessment of the whole European Forestry-Wood Chain (FWC), by quantifying performance of FWC, using indicators for all three pillars of sustainability; environmental, economic and societal. The main project product is ToSIA tool. It is decision support Impact Assessment tool that allows various end-users, such as forest-based industry, national and international policy makers and researchers to analyse the effects of changes due to deliberate actions (e.g. in policies or business activities) or due to external forces (e.g. climate change, global markets).
