Using the 1990's Input-Output Tables, the environmental loads--natural resources consumption, energy consumption and carbon dioxide emissions--of different types of civil construction activities are quantitatively analyzed and compared with the 1985's results of analysis. It is shown that 37.3 percent of the total Japanese carbon emissions in 1990 is construction related. It is increased 3.5 percent from the result in 1985. In this research, the influence of industrial structure change from 1985 to 1990 and the bubble-economy on the environmental loads of civil work is able to estimated. Recommendable basic data for calculating the environmental loads of civil work are shown here.
