Abstract:
A product environmental load evaluation method comprising:computing fuel input coefficients and inverse matrix coefficients (1-Ad) referring to an Input-Output table regarding domestic goods, the inverse matrix coefficients excluding an input coefficient matrix of imported goods regarded as domestically produced; generating emission coefficients referring to an existing data stochastic document; estimating a direct emission matrix based on the fuel input coefficients and the emission coefficients; computing environmental load of the domestic goods based on the inverse matrix coefficients and the direct emission matrix; computing an input coefficient matrix of imported goods; computing overseas environmental load emission coefficients of the imported goods based on overseas parameters every addition of an imported good, computing imported good environmental load based on the input coefficient matrix and the overseas environmental load emission coefficients; and computing product environmental load by adding the domestic good environmental load to be provided fixedly and the imported good environmental load updated every addition of an imported good.
