セメント産業は世界のCO2排出の8〜9%を占め、深刻な環境負荷を持つ。本レビューは、補助セメント材料（SCM）、代替燃料、CCSなどの緩和策を評価し、SCMと代替バインダーがクリンカ消費とCO2排出を大幅に削減できることを示す。また、循環型経済やデジタル最適化の役割にも触れ、今後の研究課題としてAI支援最適化や低炭素バインダーを挙げる。
English
The cement industry contributes 8-9% of global CO2 emissions. This review evaluates mitigation strategies including supplementary cementitious materials (SCMs), alternative fuels, and carbon capture and storage (CCS). It finds that SCMs and alternative binders can significantly reduce clinker consumption and emissions, while CCS can capture up to 90% of process emissions. The study highlights circular economy approaches and digital optimization, and calls for future research on AI-assisted optimization and low-carbon binders.

📄 Abstract（原文）
The cement industry is a fundamental pillar of modern infrastructure development; however, it is also one of the most environmentally intensive industrial sectors due to its high energy consumption, greenhouse gas emissions and depletion of natural resources. Cement manufacturing contributes nearly 8–9% of global anthropogenic CO₂ emissions, primarily due to limestone calcination and fossil fuel combustion during clinker production. With increasing urbanization and infrastructure demand, reducing the environmental footprint of cement production has become a major global challenge. This review critically examines the environmental impacts associated with cement manufacturing, including carbon emissions, energy use, air and water pollution, land degradation and resource exploitation. The study further evaluates various sustainable mitigation strategies such as supplementary cementitious materials (SCMs), alternative fuels, waste-derived materials, energy-efficient kiln technologies, carbon capture and storage (CCS) and low-carbon binders. Comparative analysis of previous studies indicates that SCMs and alternative binders can significantly reduce clinker consumption and associated CO₂ emissions, while CCS technologies have the potential to capture up to 90% of process-related carbon emissions. The review also highlights the growing role of circular economy approaches, industrial waste utilization and digital process optimization in sustainable cement production. Despite substantial progress, several challenges remain regarding large-scale implementation, economic feasibility, durability assessment and policy support. Future research should focus on AI-assisted process optimization, advanced low-carbon binders, integrated life-cycle assessment, industrial scalability of carbon-neutral technologies and sustainable utilization of agricultural and industrial wastes. The study emphasizes that achieving a low-carbon and resource-efficient cement industry requires coordinated efforts involving technological innovation, policy intervention and sustainable construction practices.
