Description and application of the EAP computer program for calculating life-cycle energy use and greenhouse gas emissions of household consumption items

摘要

Focusing on reduction in energy use and greenhouse gas emissions,a life-cycle-based analysis tool has been developed.The energy analysis program(EAP)is a computer program for determining energy use and greenhouse gas emissions related to household consumption items,using a hybrid calculation method.EAP consists of a number of fill-in screens corresponding to steps in the hybrid method,which in their turn correspond to different stages in life-cycles of consumer goods.The database incorporated in EAP comprises data about energy use and emissions of the main greenhouse gases(CO2,CH4 and N2O)concerning materials,economic sectors,means of transport,etc.The use of the program in several projects showed the applicability and usefulness of EAP in research and policy.In this article EAP is applied to food:French beans as a metaphor for fruit and vegetables.
