Abstract

Abstract

The carbon emissions from the construction industry account for nearly one-third of the total carbon emissions in China, and the potential for carbon reduction is huge. Aiming at the evaluation of carbon emission and carbon compensation in the demolition stage of the abandoned buildings, the whole life cycle evaluation method was adopted to define the calculation boundary of the demolition stage of abandoned buildings, which was divided into the demolition stage, waste transportation stage and waste disposal stage. Carbon compensation is the reuse stage of construction waste, and the calculation model of carbon emission and carbon compensation was established. Through quantitative analysis, it was concluded that carbon emissions are mainly concentrated in the construction waste disposal stage, accounting for about 75% of the total carbon emissions. The secondary recycling of construction waste could effectively reduce 31.01% of the total carbon emissions in the demolition stage of buildings, which had a good carbon reduction effect. With the increase of the secondary recycling rate of construction waste, the carbon emission of the construction waste disposal stage linearly decreased, the carbon compensation of building materials linearly increased, and the carbon reduction effect was enhanced.
