Abstract

Government has presented a guideline for the calculation of carbon emission with infrastructures in 2011, which aims to manage the GHG(greenhouse gas) emission of construction sector. Generally, the main emission sources of construction works are divided into the fuel consumption of equipments and the use of materials. This study investigated the characteristics of GHG emission with the use of equipments under the construction of railroad track. Track types are classified into ballasted track and concrete track. As a result, the specific GHG emission on the construction of ballasted track at the A line was 39.53 ton $CO_{2e}/km$ and concrete track was 25.54 ton $CO_{2e}/km$. Ballasted track showed higher specific GHG emission than concrete track because of the additional construction works by the use of gravels. In future, it is necessary to study the comparison of GHG emissions with construction methods including the use of materials. Based on these results, the low carbon construction of railroad will be established continuously.
