Most of the existing Life Cycle Assessment (LCA) research in the field of transport is ex-post evaluation. This paper proposes an LCA method in the planning phase for evaluating life cycle carbon dioxide (LC-CO2) emission from the provision of modal railway systems. As a case study, the Superconducting MAGnetically LEVitated (MAGLEV) transport system is examined. The LC-CO2 emission factors with standard infrastructure are introduced in the inventory analysis for the LC-CO2 emission. The change in LC-CO2 emission by shifting from the existing inter-regional transport mode (ordinary railways, airplanes and motor vehicles) to the MAGLEV are analyzed by the Extended Life Cycle Environmental Load (ELCEL) concept. An environmental efficiency index considering speed and capacity is also defined and the alternative transport system evaluations are conducted.
