친환경 전동차 시스템을 위한 정책과 경영전략 연구

초록

It is well known that rail has played an important role in the achievement of sustainable transport and mobility. In many great cities in the world, underground rail systems are frequently introduced to provided a permanent means of transportation that people can count on and a healthy urban environment. LCA (Life Cycle Assessment) is a tool that estimates the most relevant environmental impacts over the life cycle of a product using standardized data (Life Cycle Inventory data). In this paper, the LCA results derived from the analyses of Nordic electric rail systems are shown. The LCA result for Korean electric rail system is induced from the calculations using appropriate assumptions. The important factors to reduce environmental problems are determined from the LCA results. Based on the analyses, government policies and management stategies for and eco-efficient electric rail system are suggested. The government policies are mainly for ecternal factors such as the method of electricity generation. The management strategies made for each life cycle phase are mostly for internal factors such as the environmental management systems of the manufactureing industriy and the operator. In the case of making a policy, a high priority should be given to the feasibility of it.
