The study aimed to obtain the environmental impact data in the demolition work of the civil structure by the field survey. From the results of examining environmental impact by demolition work and transportation, the amount of the CO2 exhaust in the RC bridge was a value that was larger than that of in the steel bridge. The selection of the method of the demolition showed that a big influence was exerted on the amount of the CO2 exhaust. Therefore, it is necessary to note it from the viewpoint of the environmental impact reduction to the selection of the industrial method. The longer the bridge of the amount per the unit length of the CO2 exhaust was, the smaller. Moreover, a tendency similar as for the amount per area of the unit bridge of the CO2 exhaust was shown.
