Cement production contributes 8–9% of all anthropogenic CO₂ emissions worldwide, and further increases in the future are expected. Traditional solutions for reducing emissions, including energy efficiency, using alternative fuels, and clinker‐to‐cement ratio reduction, are insufficient to ensure the necessary mitigation. Based on the concept of material efficiency, this study identifies new alternatives for reducing CO₂ emissions by adopting a set of technological solutions to increase the industrialization of cement‐based products and the use of fillers considering a cradle‐to‐use approach. Besides, increasing the filler content in mortars and plain concrete is a desirable strategy, because it increases the carbonation rate, accelerating the CO₂ sequestration from the atmosphere. Based on data from the Brazilian cement industry technology roadmap, this study quantitatively evaluates, up to 2050, the CO₂ mitigation potential and the reduction of cement consumption for each adopted technological solution. The marginal abatement costs are also included to quantify each considered solution's cost‐effectiveness and compared with alternatives like carbon capture and storage. The results show that increasing the cement use efficiency enables CO₂ emissions reduction by up to 45% by 2050, with a cost of USD –1.36 for each avoided metric ton of CO₂, while accelerating the mortar carbonation rate.

到2050年，由于工业化和高效水泥使用，潜在的CO2减少和吸收

水泥生产占全球人为CO ₂排放量的8–9％，并且预计未来还会进一步增加。传统的减少排放的解决方案，包括使用替代燃料的能源效率，以及降低熟料与水泥的比率，不足以确保采取必要的缓解措施。基于材料效率的概念，本研究通过采用一套技术解决方案来提高水泥基产品的工业化水平，并考虑采用“从摇篮到手”的方法来使用填料，从而找到了减少CO ₂排放的新替代方案。此外，提高砂浆和普通混凝土中的填料含量是一种理想的策略，因为它会增加碳化速率，从而加速CO _{2的产生。}从大气中隔离。基于巴西水泥行业技术路线图的数据，本研究定量评估了每种采用的技术解决方案直至2050年的CO ₂缓解潜力和水泥消耗的减少量。还包括边际减排成本，以量化每个已考虑解决方案的成本效益，并与碳捕集与封存等替代方案进行比较。结果表明，提高水泥的使用效率到2050年可使CO ₂排放量减少多达45％，每避免一公吨的CO ₂成本为–1.36美元，同时加快了砂浆的碳化速度。本文满足了金-黄金JIE的要求 http://jie.click/badges中所述的数据开放性徽章。
