Full Cost Assesment Considering Social Costs for Damage to Human Health:

Case Study for Product Life Cycle of Household Electric Appliances

Abstract

LCA has already spread in industry as a practical tool that quantifies environmental impacts caused by product life cycle. Requirements of developing a methodology that involve economical aspects based on life cycle perspective are high. LCC is attractive that aggregates al of the process costs composed of product life cycle to fulfill this rquirement. However the result calculated by LCC may not be enough for environmental conscious products (ECP), because LCC does not include external costs. We performed FCA that integrates LCIA and LCC for refrigerators to confirm the significance of FCA. LCC for refrigerator using alternatives revealed higher than that of refrigerator using CFC. In contrast to the result of LCC, external cost of refrigerator using alternatives was lower than that of conventional product. It is found that the effectiveness of the conversion of CFC was higher than the increase of internal cost from the result of FCA.
