It can help mitigate climate change, reduce acid rain, and soil erosion. Japan has 4 committed itself to national targets to reduce greenhouse gas emissions to meet the Kyoto Protocol obligation of reducing greenhouse gas emissions by 6 % from 1990 levels by 2008-12. In order to attain the objective and to contribute to maintaining the global environment, studies on biomass energy should be accelerated. The most influential technology in the relatively distant future probably is hydrogen generation from biomass resources. References (1) NEDO (New Energy Development Organization). 2000.
