Abstract
This paper presents the calculation of the carbon dioxide emission by using the carbon dioxide intensities related to the Asato landslide control works site, which is located in the area of Shimajiri mudstone in Okinawa, Japan. Among the three categories of contributory causes responsible for carbon dioxide emission related to such landslide control works, namely the operation of construction machinery, the production of construction machinery and the production of building material. The category of production of building material has recorded the highest carbon dioxide output of over 65 percent, of which about 90 percent has originated from the production of cement and rolled steel in blast furnaces. The carbon dioxide emission from the operation of the backhoes, dump trucks and air compressors have accounted for about 65 percent of the emission within the category of construction machinery operations. Among the carbon dioxide emission values recorded due to the landslide control works, slope works have generated the highest percentage of emission of over 50 percent followed by the pile works and the earth works. Thus, there is a possibility of achieving a reduction of the amount of carbon dioxide emitted from landslide control works through the reduction of the production of building material.
