Abstract: The influencing factors of carbon emissions during cement production are analyzed, and a simple calculation method of element conservation to calculate carbon emissions is proposed in combination with the clinker and cement preparation process. A comparative analysis is made with the current and trial cement greenhouse gas emission accounting methods. Improving energy efficiency, upgrading green environmental protection equipment, and developing alternative fuel technologies are very practical measures to reduce pollution and carbon in recent years, supplemented by new energy technologies, carbon capture, and carbon utilization, which are expected to promote the realization of "carbon neutrality" in the cement industry.
