N2 - The carbon emission amount of the Republic of Korea ranks 8th in the world including China and the US and accordingly, the government announced its emission reduction plan by 37% compared to BAU (8.51 million tons) by 2030. As a result of the emission trading scheme that has been implemented since 2015, efforts are being made to reduce environmental load. Accordingly, this study analyzed the material-specific environmental load distribution and environmental impact category for 60 IPC girder bridges of national road constructions in Korea by utilizing the life cycle assessment (LCA) method. The analysis result was found to be in the order of ready-mixed concrete (RMC) (64.00%), rebar (9.1%), timber (7.8%) and plywood (5.6%). As for environmental impact category-specific result, it was found to be in the order of global warming (50.60%), abiotic resource depletion (32.20%), photochemical oxidant creation (POC) (10.10%) and human toxicity (HT) (7.10%), thereby considered to be helpful when selecting the form of bridge while considering environmental load during the planning and design phases.
