Biomass outtake and bioenergy development in Sweden: the role of policy and economic presumptions

In this study we review and analyse the policy design of biomass residue outtake in Sweden, focusing in particular on how public authorities specify and motivate rules and guidelines for the extraction of slash and stumps. The results show that the Swedish regulations are built on a mixed approach, including both voluntary, procedural and substantive requirements. The recommendations emphasize many merits of residue extraction, particularly climate change mitigation, new employment opportunities and reduced dependency on energy supplies from abroad. We identify a strong focus on precaution, evident in the risks for undesirable effects on nutritional balance and heavy metals in the soil, on biological diversity and on water quality in lakes and watercourses. The recommendations have remained relatively stable during the last 10 years, but the harvest of forest biomass for energy has varied. The annual harvest rate was positively related with energy prices. Harvest was much more extensive in the south, which is closer to the market. We conclude that economic presumptions have influenced the extent of slash harvest while environmental concerns seem to have limited the extraction of whole stumps. We expect that current levels of residue outtake can quickly change if the energy prices change.
