Sammanfattning

CONTEXT: There is a growing interest in investments in technology that can help farms to become fossil-free, without compromising their economic incentives, and while significantly reducing greenhouse gas (GHG) emissions. Biogas is an interesting technology in this respect, however, the possible farm-level economic impacts from investing in a biogas-based system are not well understood, yet they are decisive to understand farmers’ incentives for adoption. OBJECTIVE: The objectives are to i) develop a scenario which allows the farms to become fossil-free in their input use, ii) assess the farm-level economic consequences of adoption and iii) quantify change in global warming potential in a 100-year period (GWP100) from the biogas-scenario. METHODS: We use a stochastic partial budgeting approach to simulate farm-level economic benefits and costs associated with changes and uncertainty related to economic effects. We also use life cycle assessment for the quantification of the climate effects, which enable us to examine the potential climate impact in reduction of fossil-based inputs in baseline scenario by transitioning to the biogas scenario. The study is based on simulation for a hypothetical dairy farm with 300 milking cow and a corresponding 325 ha of arable land that produces 75 % mixed grass and 25 % clover.
