摘要：

The cement industry plays a key role in emission reduction efforts, but cement quality is rarely considered in low-carbon development analyses. Here we design three cement quality transformation routes in response to China's cement quality improvement program and analyse the corresponding low-carbon development pathways via a bottom-up integrated assessment model. Results show that cement quality improvements trigger a 14.6% increase in energy consumption and emissions in business-as-usual scenarios in 2060. Compared with the base year, raising the environmental taxes to 46.8 Chinese Yuan per equivalent unit saves up to 75.1% of carbon dioxide emissions and 25.0% of fuel consumption from the high-quality-cement scenario by 2060. Carbon capture and storage contributes up to 77% of the emission reduction. The reduction in cement demand conserves 17.3% more energy than the high-cement-demand scenario does in 2060. Collaborative waste treatment is expected to replace 22.4% of fuel consumption in the cement industry in 2060.
