基于碳足迹的低碳混凝土评价研究

Research Based on Low-Carbon Footprint's Concrete Evaluation

建材行业是碳排放大户,发展低碳建材是行业共识。碳足迹方法作为衡量温室效应和环境影响评价的重要方法,在国内外得到了广泛的应用。该文基于碳足迹原理,提出了核算混凝土碳排放的统计方法,包括混凝土原材料开采、生产、运输等各阶段。通过对上海市混凝土行业碳排放水平现状的调研,确定了评价低碳混凝土的星级指标。试点应用表明,本评价方法适用于上海地区混凝土的低碳评价,可为我国推广低碳混凝土提供参考。

Due to building mater carbon building materials is an als industry＇s enormous carbon industry consensus. As one emission, developing Iowmportant measurement of greenhouse effect and environment impact assessment, carbon footprint has been widely used in domestic and abroad scale. This article is based on low-carbon footprint principle, it brings up the concrete carbon accounting statistical methods, including concrete raw materials extraction, production, transportation and other various stages. By survey of carbon emission in shanghai status quo concrete industry, it determines the STAR evaluation index of low-carbon concrete. Pilot field applications show that the evaluation method is applicable to low-carbon concrete assessment in shanghai area, which provides a reference for promotion of low-carbon concrete in our country.
