Abstract

In general, the rail transportation recognized as a better transportation mode than road transportation in terms of the environment. However, due to a lack of quantitative analysis based on Korean data, foreign cases for environmental advantages of the railway have often been cited in Korea. To address this issue, we estimated the energy consumption of passenger and freight transportation using certified activity data from Korea Railroad Statistics and the Electrical Work Report for railway and the Energy Consumption Survey for road. We estimated the Green House Gas emission of passenger and freight transportation on a Tier 1 level by applying the IPCC 2006 Guideline. Finally, we calculated the energy consumption unit and GHG emission unit to determine the environmental impact of rail and road transportation. We also compared the analyzed results of high-speed rail and auto as typical means of rail and road transportation.

일반적으로 철도는 환경적 측면에서 대단히 우수한 수단이며 도로보다 환경적으로 우위성을 갖고 있다고 인식되어왔다. 하지만 아직 우리나라에서는 철도의 환경적 우위성에 대하여 대부분 외국 사례를 인용하여 온 것이 대부분이며 우리의 자료를 바탕으로 정량적으로 분석한 연구가 부족한 것이 현실이다. 이에 본 연구에서는 철도는 철도통계연보와 한국철도공사의 전기업무자료를, 도로는 에너지 총조사보고서를 활동도 자료로 이용하여 여객과 화물의 에너지 소비량을 산정하고 IPCC 2006 가이드라인을 적용하여 Tier1 수준의 온실가스 배출량을 산정하였다. 최종적으로 환경적 영향을 파악하기 위한 차종별로 여객과 화물의 에너지 소비 및 온실가스 배출 원단위를 산정하여 보았다. 또한 철도와 도로 여객수송의 대표적인 수단으로 고속철도와 승용차의 산정결과를 비교하여 보았다.
