The globalization and the development of IT in the economic society in recent years promote the expansion of an international, interactive transportation. Therefore, the concentration of the cargo on the container terminal continues and the importance of ports in distribudon increases further.
　On the other hand, contributing to the decrease of the environmental burden and the construction of the recycling-based society is an important issue in the transportation field.
　In this paper the method of calculating the carbon dioxide emission in the container terminal was examined. And the case study was executed for one of the major port in Japan and total carbon dioxide emissions were calculated. As a result, the amount of the carbon dioxide emission of an each transportation mode of the sea, land and the terminal became the same order value. Accordingly, it is thought that the carbon dioxide reduction measures in each transportation mode are effective of the sensidvity at the same level.
