Abstract: In the context of mitigating climate change through decarbonizing the energy system, we developed a methodology for life cycle analysis (LCA) on electricity generation system in the Process Chain Analysis (PCA) approach. The methodology, developed based on the first principle, can streamline the formulation of the life cycle energy system and provide clear depiction on the elementary mechanisms of the input-output interactions across the system boundaries. The resulting system boundaries can facilitate the use of the Kaya Identity and decomposition concepts to objectively establish the ?cut-off? criteria for an LCA-PCA exercise. From the case studies on nuclear power plants, the methodology can estimate with good confidence the life cycle carbon emission factor of existing electricity generation systems. It is also capable of projecting the life cycle energy input and carbon emissions of future electricity generation technologies. Moreover, the methodology allows for sensitivity analysis of key design parameters of energy systems.
