Reduction of Life Cycle Environment Pollutant Load by Environmentally Sound Actions on Replacement of Household Appliances

Recently, global environment problems have been actualized and they are caused by accumulated effects of pollutant load derived from citizens' daily activities. Life-Cycle-Assessment (LCA) is powerful tool for estimation of total environmental effect of some appliances and services. But it is not easy to execute LCA for strict environmental assessment. In this study, we tried to evaluate multiple environmental pollutant loads and applied to estimate the environmental effect of replacement of household electric appliances and automobile. The replacement from an old household appliance to new one which has higher efficiency of utilizing energy, and from a small appliance to bigger one which has more additional values was estimated. Both cases were estimated to bring increasing of environmental pollutant load whenever drastic improvement of efficiency of energy consumption and effluent is not expected in utilization stage. Finally, Eco-Factor derived from BUWAL-SR133 was tried to estimate total environmental effect of these problems.
