摘要

摘要: 建筑业碳排放占全国总碳排放的近1/3，减碳潜力巨大。针对建筑废弃拆除阶段碳排放及碳补偿评价问题，采用全生命周期评价方法界定建筑废弃拆除阶段计算边界，将其划分为建筑拆除、废弃物运输和废弃物处置阶段，碳补偿为建筑废弃物再利用阶段，并建立碳排放及碳补偿计算模型。通过量化分析得出：碳排放主要集中于建筑废弃物处置阶段，约占总碳排放的75%。建筑废弃物二次循环利用，可有效降低建筑拆除阶段碳排放总量的31.01%，具有良好的减碳效果。随着建筑废弃物二次回收利用率增大，建筑废弃物处置阶段的碳排放线性减少，建筑材料碳补偿线性增加，减碳效果有所增强。

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.
