Concrete was identified as the significant GHG emission source resulting from a GHG emission analysis of railway infrastructure. An environmental assessment method (life cycle assessment; LCA) and low carbon railway infrastructure design strategy development method (ECODESISGN PILOT) were applied to develop low carbon railway infrastructure design strategies. The railway infrastructure was analyzed as a raw material intensive industry emitting large amount of greenhouse gas (GHG) at its construction stage. Therefore, in this study, it is analyzed that current status of GHG emission at its construction stage, and a method reducing GHG emission of railway infrastructure is proposed. In this study, eco-concrete, concrete aging prevention agent and a low carbon railway route decision method based on a need of low carbon railway infrastructure construction technology application for green railway development were considered.
