蒸压加气混凝土砌块产品碳足迹评价方法和实证研究

Products Carbon Footprint Evaluation Method and Empirical Analysis of Autoclaved Aerated Concrete Block

在“双碳目标”的背景下,蒸压加气混凝土砌块碳足迹评价有利于掌握砌块产品的温室气体排放途径及排放量,在碳足迹精细化管理的基础上引导企业进一步发掘减排潜力,为服务“双碳目标”提供保障。文中首先探讨了蒸压加气混凝土砌块产品碳足迹评价方法,包括确定评价范围、评价单元、统计周期、数据获取、碳排放计算等;然后结合某企业实证案例进行分析研究,计算该企业的碳排放量和单位产品碳排放量;最后评价低碳产品的单位产品碳排放量是否符合T/CBMF28-2018的限值要求。

In the context of“carbon peak and neutrality targets”,the carbon footprint evaluation of autoclaved aerated concrete blocks will help to grasp the greenhouse gas emission pathways and emissions,and help enterprises to explore the emission reduction potential on the basis of fine management of carbon footprint and provide safeguard for serving“carbon peak and neutrality targets”.This paper firstly discusses the carbon footprint evaluation method of autoclaved aerated concrete block products,including determination of evaluation scope,evaluation unit,statistical period,data acquisition,carbon emission calculation,etc.Then the actual case of a company is analyzed to calculate the carbon emissions and unit product carbon emissions of an enterprise.Finally the unit product carbon emissions of low-carbon products are assessed to meet the limit requirements of T/CBMF 28-2018.
