建筑行业对于国民生产和社会发展具有重要意义。建筑行业碳排放总量占全国碳排放超过半数,因此,建筑行业的减碳工作对于我国是否能顺利完成“双碳”目标至关重要。本报告深入分析了建筑行业的碳排放现状,详细描述建筑全生命周期的碳排放情况,针对国内外的绿色建筑、建筑节能减碳的标准和政策进行了系统总结,深入探讨建筑碳标签的基准机制和国内外现状。研究表明,目前我国建筑碳排放主要来源于建材生产和建筑运行阶段能耗。建筑行业的碳标签制度尚处于摇篮阶段。随着绿色建筑和“双碳”相关政策的不断推进,未来建立建筑行业碳标签机制需要从构建基础方法学、建立基准机制、评价标准和行业推广等多个维度开展。
<<The construction industry is important to social development. The total carbon emissions of the construction industry account for more than half of the China’s carbon emissions. Therefore,the carbon reduction work of the construction industry is crucial to successfully achieve the “dual carbon goal”. This report fundamentally analyzes the current situation of carbon emissions in the construction industry. The carbon emissions of the whole life cycle of buildings are described in detail. The national and international standards and policies for green buildings,building energy conservation and carbon reduction are systematically described. It is found that China’s building carbon emissions are mainly generated from the production of construction materials and the energy consumption during the building operation. Carbon labelling in the construction industry is still in its infancy. With the continuous development of green buildings and the “dual carbon target” related policies,the establishment of carbon label mechanisms in the construction industry needs to be carried out in a variety of directions,such as the establishment of methodologies and benchmarking mechanisms,the research on assessment standards and the industry promotion.
