The importance of environmental protection is frequently noted because of the occurrence of environmental problems, such as waste and air pollution. For example, the reduction of CO_2 emissions was discussed at the Kyoto Conference. As a result, the necessity for the realization of products that perform better environmentally has been emphasized. Life Cycle Assessment (LCA) has been proposed as a method of grasping the environmental load, occurring especially in product manufacturing, in order to design and manufacture products with better environmental performance. LCA is a technique for computing the environmental load of a product over the total product life cycle by performing inventory analysis of each life cycle process and summing up the results. However, since LCA computes environmental load based on a static database, it is difficult to consider dynamic changes of a life cycle in its calculation, for example, the timing of the reused parts, the time change of the environmental load, and unevenness of the products and process. In this research, we propose the new environmental load evaluation system, which can consider dynamic changes of each life cycle process by connecting external calculating modules to the LCA system.
