11 Policy Tools 1970s: Oil crisis, Swedish government ration gasoline and heating oil 1970: Research grants and investments on bioenergy developments. Includes plantations. 1980s: First commercial plantations s: Plan for de-regulation of Swedish agricultural sector 1990s: Programmes for economic/policy incentives for plantations 1995: Sweden joins the EU. CAP implemented

12 Policy Tools Swedish measures to encourage Willow cultivation a) SUBSIDIES : Generic subsidy of 1200 EUR/ha for farmers that would change from cereal to other activities : 1330 EUR/ha specific for willow production ECU for fencing b) TAXATION Taxes on sulphur and CO 2 in heat production increased. (biofuels exempted)

18 Instruments Policy incentives are not coordinated The policy incentives are not symmetrical: placed on the supply side (specific to willow) not placed on the demand side (are generic for biomass for energy) Coordination?
