水泥占全球温室气体排放量的7%，预计将随着发展而增长。大部分用于混凝土，这是全球最常见的建筑材料。因此，减少建筑物中使用水泥和混凝土的排放对于限制全球变暖至关重要。然而，在了解这些排放的程度方面仍然存在多方面的差距。本文是一个项目的第一个成果，该项目旨在更好地了解建筑物中使用混凝土的具体影响，以便为政策制定者和行业从业者提供信息和建议，并为前进的道路提供明确的证据。为了做到这一点，该项目整理，分析和批评来自多个来源的证据，报告了三篇论文。这第一篇论文的重点是材料影响的基本数据。在过去的几年里，已经发布了数百个水泥、骨料和混凝土混合物的环境产品声明（EPD），但没有出版物提供比较或概述。因此，对减少混凝土影响的范围和机会的了解仍然非常有限。本文首次详细分析了混凝土及其组分的EPD。
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 that aims to understand better 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, the project 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 the reduction of impacts from concrete remains very limited. This paper provides the first detailed analysis of the EPD for concrete and its constituents.
