Cement and Concrete EPD References

List of Environmental Product Declarations (EPD) analysed for cement, aggregates, admixtures and ready mix concretes and described in a paper in review for Buildings and Cities, Embodied carbon of concrete in buildings: Part 1 - Materials<b>Abstract</b> Cement is responsible for 7% of global greenhouse gas emissions, and is predicted to grow with increasing development. The majority is used in concrete, globally the most common material in buildings. Reducing emissions from the use of cement and concrete in buildings is therefore critical in order to limit global warming. However there remain multiple gaps in knowledge about the extent of these emissions. This paper is the first output of a project which aims to better understand the embodied impacts from the use of concrete in buildings, in order to inform and advise policy makers and industry practitioners, and to provide clear evidence for the path forwards. In order to do so it collates, analyses and critiques evidence from multiple sources, reported over three papers. This first paper focuses on the basic data on materials impacts. Over the last few years several hundred individual Environmental Product Declarations (EPD) have been published for cements, aggregates and concrete mixes, but no publication offers a comparison or overview; therefore understanding the range and opportunities for reduction of impacts from concrete remains very limited. Part 1 - Materials provides the first detailed analysis of the EPD for concrete and its constituents.本数据集为针对水泥、集料、外加剂及预拌混凝土的环境产品声明（Environmental Product Declarations, EPD）分析汇总集，相关研究成果已以论文形式投稿至《Buildings and Cities》期刊，论文题为《建筑中混凝土的隐含碳排放：第1部分——材料》。 **摘要** 水泥占全球温室气体排放总量的7%，且伴随全球发展进程的推进，其排放量预计将持续攀升。水泥的核心应用场景为混凝土——这是全球建筑领域使用最广泛的材料。因此，降低建筑中水泥与混凝土使用环节的碳排放，对遏制全球变暖具有关键意义。然而目前学界对这类排放的实际规模仍存在诸多认知盲区。 本研究为某科研项目的首批产出成果，该项目旨在系统解析建筑用混凝土的隐含环境影响，为政策制定者与行业从业者提供决策参考，并为行业发展路径提供明确的实证依据。为达成上述目标，本文将分三篇论文梳理、分析并批判性评估多源研究数据。本第1部分聚焦于材料环境影响的基础数据集。 近年来，全球已公开数百份针对水泥、集料与混凝土配合比的独立环境产品声明，但尚无相关出版物对其进行系统性对比或综述，因此学界对混凝土碳排放的影响范围及减排潜力的认知仍十分有限。本《第1部分——材料》首次对混凝土及其组分的环境产品声明开展了全面细致的分析。
