🏛政策担当者:Highlights policy levers and standardization needs to accelerate green cement adoption, relevant for national decarbonization roadmaps.

The cement industry is responsible for approximately 8–10% of global carbon dioxide (CO₂) emissions, making it one of the largest contributors to climate change and environmental degradation. The transition toward green cement has emerged as a critical strategy for reducing the environmental footprint of the construction sector while supporting global net-zero and circular economy objectives. This review synthesizes recent advances in green cement technologies, emphasizing sustainable raw materials, supplementary cementitious materials, waste-derived alternatives, energy-efficient manufacturing processes, and emerging low-carbon innovations. The paper examines the environmental, economic, and engineering performance of green cement compared with conventional Ordinary Portland Cement (OPC), highlighting improvements in durability, resource efficiency, waste utilization, and greenhouse gas mitigation. Furthermore, the review discusses current industrial developments, policy initiatives, and technological innovations that are accelerating the adoption of sustainable cement production, with particular reference to India's rapidly growing cement industry. Despite significant progress, several challenges including high initial investment costs, limited standardization, raw material variability, technological barriers, and market acceptance—continue to constrain large-scale implementation. The review identifies future research priorities focusing on carbon capture and utilization, alternative binders, digital manufacturing technologies, artificial intelligence-driven process optimization, and life-cycle assessment for enhancing sustainability performance. The findings demonstrate that green cement technologies can substantially reduce carbon emissions while maintaining structural performance, thereby providing an effective pathway toward sustainable construction and climate-resilient infrastructure. This review offers valuable insights for researchers, industry practitioners, and policymakers seeking to accelerate the decarbonization of the global cement sector.
