摘　　要：将Input-Output分析方法引入LCA评价中,建立了Hybrid LCA评价方法。利用该方法对煤基M100(100%甲醇)车用替代燃料生命周期温室气体排放进行评价。结果表明:相同热值煤基M100燃料温室气体排放比传统汽油高许多,因此建议在生产阶段采用CO2捕集和储存技术和重点提高煤炭燃烧利用效率。Applying the input-output method to LCA, the input-output hybrid LCA assessment is established. With this method,life cycle greenhouse gases emission of coal-based Methanol 100 as an alternative vehicle fuel are analyzed. Compared with traditional gasoline with same heat value, coal-based M100 will result heavier greenhouse effect, So application of carbon captured and storage equipments is suggested in the production stage and the combustion efficiency of coal should be improved greatly.
