Temporal Validity of Energy System Life Cycle Carbon Emissions in China

Abstract:

Energy system life cycle inventory database is the base of a product or system life cycle assessment. Due to a great variety and rapidly update frequency, the temporal validity of parameters should be considered in uncertainty analysis of life cycle assessment of energy upstream stage. Ten key parameters related to energy system life cycle carbon emission were screened by combined sensitivity and parameter time validity analysis, and the update interval of key parameters was devised. This method can reduce the maintenance workload of the database, and provide a foundation for improving the reliability of the product or system life cycle.
