This report is part of the REFUEL project, in which a road map for biofuels in the EU27 up to 2030 is developed. It is one oh nine reports, 8 describing ther different workpackages and one final report summarizing and drawing general conclusions. This report describes the methodology followed to estimate the European somestic biomass rresource potential and related costs. It does so for three projection estimates concerning agriculktural food production; a lower, base and higher estimate. The concrete results include spatial cost and dedicated bioenergy production potential over view for Europe (EU-27, Norway, Switzerland and Ukraine).
