In the meantime Railway sector short of detail study about green house gas emission reduction and CO₂ emission volume assessment and estimation, Gradually increase of need green house gas management consider of construction Life Cycle in design phase.
Many countries of the world are present of vision and road map for green house gas reduction and establish various politics. To achieve green house gas reduction target many countries are setting up the action plan.
Therefore Railway sector need to figure out the volume of green house gas emission during construction phase to compete to other transportation as low CO₂ green traffic means
In this study, through the case study of Track bed, Track and Architecture in the Honan High Speed railway Project to assessment of Major green house gas emission such as equipment and material and it is possible to estimate now construction line by the basic unit standardization
Hereafter, base on this study need to green house gas emission management guideline by government for methodical management of eco friendly railway design criteria and management target of green house emission volume in construction field and constructor need to give effort to reduction performance voluntary.
