This study investigates the characteristics of environmental impact from the construction phase of a high-speed railway through a Life Cycle Assessment method based on the materials used and the energy consumption of the equipment used according to the design statement. The results reveal that the contributions to environmental impact in the construction sector of a high-speed railway were 89% for civil engineering, 7% for the track system, 2% for stations and 2% for the energy and telecommunication system. In particular, the highest contribution to the impact in the civil engineering category were 54% for Global Warming, 25% for Abiotic Resource Depletion and 8% for Photochemical Oxidant Creation. The main influence factors were the use of remicon and cement. In future, the application of Life Cycle Assessment for the construction sector of railway construction will introduce efficient reduction methods according to the quantitative calculation of environmental impact.
