Evaluation of Carbon Emissions According to the Steep Slope Maintenance Project

Abstract

Reducing carbon emissions due to climate change has emerged as a national objective. To achieve carbon-free emissions nationally by 2050, evaluating and reducing carbon emissions is essential for efficient disaster management. In this study, a method for quantitatively evaluating carbon emissions in disaster management projects was proposed. Disaster management projects were divided into detailed processes, and in each process, the extent of equipment operation and amount of raw material used for unit construction work were presented using standard production of construction work. The carbon emissions resulting from equipment operation and material usage were based on the standards given by the Ministry of Land, Infrastructure, and Transport. Finnally, amount of carbon emissions for unit construction volume during each detailed process were estimated. Using developed methods, carbon emissions were calculated at the steep slope maintenance project. The results indicated that 89.4% of the total carbon emissions were generated from pouring concrete, such as cement and ready-mixed concrete. Thus, reduction of cement and concrete usage is essential for reducing carbon emissions in disaster management projects.
