This paper aims to provide common basis for the estimation of emission inventory data necessary for the evaluation of environmental impact of a concrete structure through its life cycle. Intensive literature survey and hearing to the institutes concerned have been deliberately conducted to collect relevant data to concrete materials, other materials involved, construction, demolition, and disposal and recycling. Consequently emission inventory data of CO2, SOx, NOx, and particulate matter were able to be prepared in an objective way. In addition, fundamental inventory data of these emission gases and particulate matter were provided for various kinds of energy. Furthermore most commonly used machines, instruments and other equipments on concrete structure construction are presented and provided for their related inventory data. In this way, inventory data regarding 91 detail items in total were able to be provided. By using these inventory data, four case studies where environmental impact caused by the construction of concrete structures was considered as a performance parameter of the structures similarly to serviceability, safety, and durability of the structures were also investigated based on design methods proposed previously by the authors in order to confirm the applicability of these inventory data to environmental performance evaluation of concrete structures.
