Comparison of Domestic and International Specific GHG Emission with Infrastructure Construction of High Speed Rail

Recently, as the policies on GHG reduction have been reinforced, there are studied variously the researches to calculate and manage GHG emission at the infrastructure construction as well as during the operation in transport. So, this study aimed to assess specific GHG emissions between domestic A line and international examples at the infrastructure construction of high speed rail. Generally, the GHG emission sources of construction step were the energy consumption of heavy equipments and the use of materials. As a result, the specific GHG emission of A line was similar to the Taipei-Kaohsiung (Taiwan) and the Beijing- Tianjin (China) lines. These trends were resulted because the lengths of tunnel and bridge in Asia were longer than in Europe. In future, the comparison of specific GHG emission at the life cycle of construction step will be applied to develop the GHG reduction method of rail infrastructure.
