We estimated GHG (Greenhouse Gas) emissions based on life cycle inventory analysis for electric power generated by forest residues. In studying 2 kinds of forest residues (Case 1: Associated with pre-commercial thinning, Case 2: Associated with final cutting) in Hokkaido, the system boundary was from collecting of forest residues to burning (power generation). Moisture content of forest residue in burning (power generation) was defined as 50% (oven dry basis). The highest and lowest GHG emissions were 1.27 and 0.10 kg-CO(2)eq/kWh, respectively. There is the potential for an increase in GHG emissions for electric power generated by forest residues depending on kind of residue, type of boiler and power generation efficiency.
