Abstract: | Life-cycle assessment (LCA) is environmental evaluation of products, materials, and processes over their life cycle. Truncation
uncertainty and corresponding uncertainty are main problems occurred in process life cycle assessment (PLCA) modeling and
economic input-output life cycle assessment (EIOLCA) modeling. Through combination of these two modelings in different life
cycle stage and use of an uncertainty reduction strategy, a hybrid life cycle assessment modeling method was proposed in this
study. Case studies were presented on gasoline-powered motorbikes (M-bike) and electricity-powered electric bike (E-bike).
Web-based software was developed to analyze process environmental impacts. Results show that the largest part of life cycle
energy (LCE) is consumed at use stage. Less energy is consumed in life cycle of E-bike than that of M-bike. GWP (Global Warming
Potential), CO (Carbon Monoxide), PM10 (particulate matter) emission of M-bike are higher than that of E-bike, especially
at use stage, AP (acidification Potential) emission of E-bike is higher than that of M-bike. Comprehensively, E-bike is energy
efficient and less emitting, and better choice for urban private transportation.
