Abstract This paper, which is a contribution to the UNEP series on Eco-Efficient Cements, examines the role of material-based solutions to reducing CO 2 emissions from cement production considering factors that could influence implementation. Global urbanization has led to an increase in demand for cement and cement-based materials. With its growth in consumption, the associated CO 2 emissions from its production are raising concern. However, the role of mitigation strategies in a global context that account for regional material availability and degree of market adoption have yet to be considered. This work shows that the 2 °C scenario targets for 2050 can be met through increased use of calcined clay and engineered filler with dispersants. The introduction of new Portland clinker-based cement alternatives, use of alkali-activated materials, and improvement of efficiency of cement use could further contribute to reduction goals. There are currently-available technologies for reduction that could be rapidly implemented.

到 2050 年全球水泥行业的二氧化碳减排潜力

摘要 本文是对环境署生态高效水泥系列的贡献,研究了基于材料的解决方案在减少水泥生产中的 CO 2 排放方面的作用,并考虑了可能影响实施的因素。全球城市化导致对水泥和水泥基材料的需求增加。随着消费量的增长,其生产中相关的 CO 2 排放引起了人们的关注。然而,考虑到区域材料可用性和市场采用程度的缓解策略在全球范围内的作用还有待考虑。这项工作表明,通过增加使用煅烧粘土和工程填料和分散剂,可以实现 2050 年的 2°C 情景目标。引入新的基于波特兰熟料的水泥替代品,使用碱活化材料,提高水泥使用效率可以进一步促进减排目标。目前已有可快速实施的减排技术。
