¿ä¾à2 Along with the increasing interest in environmental problems such as global warming, the South Korean government has established policies and regulations to reduce the amount of greenhouse gases, targeting a 30% reduction of CO2 compared to business-as-usual levels by 2020. Thus, there have been many studies in construction field to control and reduce the amount of CO2 emitted from buildings. CO2 emission from the building construction could be obtained by using the life cycle assessment(LCA) methodology. In LCA, it is essential to have life cycle inventory(LCI) data of construction materials consisting of CO2 emission data that have been defined and examined in a detailed way in order to obtain more accurate and detailed CO2 emission of buildings. To date, however, the LCI data have been acquired only for the representative materials. Accordingly this study aimed to propose detailed CO2 emission data for steel rebar and H-beam, which are the essential structural steel materials, by strength and type. To accomplish the objective, this study used Input-Output LCA methodology which is based on the Input-Output table. It is believed that the CO2 emission data of steel materials acquired from this study would allow a more accurate assessment of CO2 emission for diverse structural design alternatives.
