By using ISO "life cycle assessment principles and framework",energy consumption and environmental emissions of vehicle biogas life cycle for anaerobic fermentation of municipal waste are analyzed. Life cycle analysis method based on PELCA (Hybrid Life Cycle Assessment)hybrid modeling is proposed, and vehicle biogas for anaerobic fermentation of municipal waste in Anyang city is evaluated with life cycle assessment. The results show that the biogas fully meets the requirements of vehicle CNG (Compressed Natural Gas). In life cycle assessmentof vehicle biogas, global warming is the largest contribution to the environmental impact load, and aerosol is the smallest. In environmental impact load of vehicle biogas fuel life cycle, the largest contribution to the environmental impact load is in vehicle operation phase, and the least is in fuel stage. The wastedisposal methods for anaerobic fermentation of municipal waste could be used asreference information for urban policymakers.
