Korea Rail and Road Energy and GHG Footprint Assessment using Input-Output Analysis

초록

In current study, we employ primary data from the BOK, KEEI, and KRRI and introduce an energy input-output model to estimate a footprint of energy consumption as well as CO2 emission of Korea passenger rail and road transport for the year 2005. Scope of study includes energy production, material preparation, manufacturing, construction, and operation. Results in calculation are normalized by a functional unit of pkm. Uncertainty analysis is performed to communicate a reliability of result. A scenario demonstrating the potential effect of CO2 reduction induced by modal shift is conducted.
