Abstract: Global biomass trade has risen sharply in recent decades. This development was accompanied by increasing concerns about adverse environmental impacts in exporting countries. In Austria, strong preference for food and bioenergy from domestic sources is prevalent, while especially biomass imports for energy are met with scepticism. We here investigate where biomass consumed in Austria originates from, and compare the source-region composition of biomass used for food, energy and material. High product-level detail is achieved by combining a physical consumption-based accounting approach with national statistics and process chain modelling. We find that 55% of the total biomass consumed in Austria originates from domestic forestry or agriculture and 30% from neighbouring countries. In all three use categories, the products with the largest biomass footprints (beef, pork, milk, cereal products, paper, wood fuels) are almost entirely sourced from Central Europe. Biomass originating from non-EU countries accounts for 7.6% of the primary biomass footprint and is most relevant for food (13%), primarily due to livestock feed imports. Although oil crop-based biofuels have relatively large primary biomass footprints overseas, bioenergy in Austria qualifies as more regional than food and material products.
