디젤기관차의 온실가스 배출계수 측정방안 연구

As the governmental efforts have been performed for Climate Change Prevention in Korea, it is necessary to develop GHG reduction methods for the railroad operations and compile more detailed GHG emission inventories. However, GHG emission factors are presented only as tier 1 level in the IPCC guideline and these values doesn't reflect characteristics of Korean railroad. The purpose of our research was to suggest the measurement method for GHG emission factors of diesel locomotives. So we researched a current development status of GHG emission factors and performed an experiment about it. As a result, GHG concentrations and diesel consumption were changed in the increase of notch of diesel locomotives. In the future, the GHG emission factors of diesel-powered railcars will be improved by tier 2 and 3 level.
