The sustainability indicators used in EFORWOOD project need to be defined that are valid for the whole FWC. Indicators for all three pillars of sustainability – in relation to the whole forestry wood chain (FWC) – are used (10 environmental, 9 economic and 8 social indicators).  The indicators have been chosen with due reference to and consideration for all relevant indicator development processes on sustainability indicators in the EU. This applies in particular to EU sustainable development indicators and the EU Sustainability Impact Assessment Guidelines.
