SUSTAINABLE CONSTRUCTION AND CO2 EMISSIONS

Abstract

Both Green Building Index (GBI) and Comprehensive Assessment System for Built Environment Efficiency (CASBEE) sustainable construction certification acknowledged the atmospheric emissions, hence signify the importance of the CO2 emissions measurement for every construction project in the world. Gross Domestic Products of Japan and Malaysia both resultant to 10 and 18.6% in 2012, from the construction industries and believes to increase by years due to rapid urbanisation demand of both countries. Therefore, propagate the strategic stakeholders of the project to play challenging roles in combating the CO2. This paper supports by contributing several numbers of strategic plans in mitigating this issue. In addition, this paper also provides a fundamental evaluation to CO2 as the environmental performance indicator for a project. This research investigates on the CO2 emissions in bore piling concrete structure construction. Malaysian 2014 CO2 inventory data that were developed by this research are being adopted in the analysis. The life cycle assessment of bore piles- construction and transportation resultant to 20,910.54 kg-CO2/m3. Comparisons were made with Japanese findings. It is found that the volume of concrete is not the significant factor of CO2 emissions, but amount of combustions from machineries and transportation contributes to the CO2 emissions. This paper enhances the strategic environmental planning in order to reduce the CO2 emissions that were ground from the construction activities.
