Abstract: In South Korea, efforts to reduce carbon dioxide emissions and environmental impacts from the perspective of life cycle assessment (LCA) are important because of the implementation of zero-energy building certification for public buildings and the promotion of net-zero policy. Therefore, it is critical to develop cement alternatives with low embodied energy and less environmental impact. In this study, the applicability of “highly sulfated calcium silicate cement (HSCSC),” an eco-friendly binder developed by our research team, was investigated. Its basic properties and environmental footprint reduction effects were examined in comparison with ordinary Portland cement (OPC) and Portland blast furnace slag cement (PBSC). The environmental impacts of the HSCSC were analyzed using the LCA method. The results confirmed that HSCSC can be considered an excellent alternative to conventional OPC or PBSC in certain areas as an eco-friendly binder that can reduce carbon dioxide emissions and environmental impacts. Moreover, compared to OPC and PBSC, the probability of HSCSC affecting the human body is extremely low. The results of this study may contribute to the development and practical use of cements that minimize climate impacts, as well as improve the efficacy of future research on embodied energy saving.
