Research Methods of Carbon Emissions

Abstract

As a pillar industry, the construction industry generates 28% of the total carbon emissions of the whole society throughout its life cycle. Through the carbon emission ratio of the whole life cycle of existing buildings, it is found that the carbon emission per unit time in the construction phase is the highest among all phases, and the various environmental pollution caused by it is also the most concentrated. In order to achieve low carbon construction and reduce environmental pollution, relevant parts of the country have promulgated building construction management documents since 2007. The documents put forward clear requirements for green and low-carbon urban and rural construction to ensure green and low-carbon construction activities. It can be seen that in the context of the "two carbon" strategy, carbon emission monitoring and carbon emission reduction of construction have attracted wide attention from all walks of life. In this paper, through the analysis of carbon emission monitoring methods of construction projects, a carbon emission calculation model based on carbon sources and sinks of the construction process is established to realize the quantitative calculation of carbon emission in the construction phase of construction projects. It also establishes a carbon emission monitoring method for the construction phase of the construction project, which provides practical guidance for the carbon emission data monitoring of each construction project and guides the real-time monitoring of carbon emission during the construction phase of the construction project.
