Abstract

To reasonably quantify the greenhouse gas(GHG) emission intensity and level of opencut metro station construction, life cycle assessment method is adopted to conduct GHG emission assessment of opencut metro station in the construction phase. In addition, a GHG emission calculation formula for opencut metro station in the construction phase is established, and GHG emission intensity and level are quantitatively analyzed in case studies. The research results show that the total GHG emissions of the case opencut metro station in the construction phase are 47 718.61 tCO2e. Among them, the production, transportation, and construction of building materials account for 88.91%, 3.92%, and 7.12%, respectively. The GHG emission intensity in the construction phase of the opencut metro station is 335.52 tCO2e/100 m2. The research results can provide a theoretical basis for promoting the green and lowcarbon transformation in the field of urban transport.
