Abstract

Recent international environmental regulations are focused on reducing pre-contamination and on sustainable development prior to the usage stage of a product. The Environmental Performance Declaration is being used as a tool for quantifying the environmental performance of products, to reduce contamination in advance, and for advertising the results of railway vehicles in Europe. In this study, a life cycle assessment of the tilting train was conducted, the first such case study in Korea, according to the ISO 14025 standard and Korea EDP (Environmental Declaration of the Product) rule. As a result of the LCA, the life cycle carbon emission of the tilting train was determined to be $3.54{\times}10^7kgCO_2eq.$ which is higher than that of a European train. Also, the amount of $CO_2$ emission of the Mcp and car body is higher than that of the other car and bogie.

국제환경규제는 제품사용단계에서 발생한 환경오염에 대한 사후처리방식에서 설계단계에서 사전환경 오염차단과 자원순환으로 전환하고 있다. 사전환경오염 차단도구로는 제품의 환경성능을 정량화하고 이러한 정보를 객관적으로 제공하는 환경성 인증제도가 활용되고 있으며 유럽에서는 이를 구매단계부터 적용하고 있다. 본 연구에서는 국내 최초로 틸팅열차를 대상으로 ISO 14025기준과 환경부 환경성적표지제도의 작성지침에 따라 전과정평가를 수행하였으며 그 결과를 제시하였다. 틸팅열차 1편성의 생애주기 온실가스 총배출량은 $3.54{\times}10^7kgCO_2eq.$로 분석되었으며 이는 유럽의 동일한 철도차량 온실가스 배출량과 비교할때 높은 수치이다. 차량별 온실가스배출량 분석결과 동력분산식임에도 Mcp차량의 배출량이 상대적으로 많았으며 차체의 배출량이 대차보다 높음을 확인하였다.
