Abstract: To solving the problem of supporting decision making in product environmental Life Cycle Assessment (LCA),the comparison between Attributional Life Cycle Assessment (ALCA) and Consequential Life Cycle Assessment (CLCA) and the marginal technology determination of CLCA were discussed.Based on partial equilibrium model and general equilibrium model,the CLCA model was constructed,the CLCA model with rebound effects and experience curve was considered and case applications for all these models were analyzed.The research showed that CLCA was an effective environment tool for supporting decision making and an assessment method by combining the traditional LCA with economical model.Through considering the market factors especially the product substitution effect,the CLCA method could analyze the changes of both energy and environment influence when the product system marginal changes.

Key words: life cycle analysis, consequential life cycle assessment, attributional life cycle assessment, equilibrium models, rebound effects, experience curve
