철도건설단계에서의 온실가스 저감방안 연구

초록

As the use of railroad has been increased as a green transport mode, the GHG inventories of railroad construction as well as railcar operations and the calculation methods of emissions have been studied. In this study, international trends for the GHG reduction of railroad construction were investigated and the reduction effects of GHG were estimated by the introduction of renewable energies. First of all, the used heavy equipments should be improved to reduce the GHG emissions of railroad construction. In addition, the renewable energies should be used widely from the design step for a new railroad route. For example, 100kW of solar power can decrease 49.5 tCO2e and 750kW of wind power is 557 tCO2e. In the future, railroad should be constructed considering GHG emissions to enhance the investment.
