This study analyzes current energy and carbon dioxide (CO2) emission trends in China's cement industryas the basis for modeling different levels of cement production and rates of efficiency improvement andcarbon reduction in 2011-2030. Three cement output projections are developed based on analyses ofhistorical production and physical and macroeconomic drivers. For each of these three productionprojections, energy savings and CO2 emission reduction potentials are estimated in a best practicescenario and two continuous improvement scenarios relative to a frozen scenario. The results reveal thepotential for cumulative final energy savings of 27.1 to 37.5 exajoules and energy-related directemission reductions of 3.2 to 4.4 gigatonnes in 2011-2030 under the best practice scenarios. Thecontinuous improvement scenarios produce cumulative final energy savings of 6.0 to 18.9 exajoules andreduce CO2 emissions by 1.0 to 2.4 gigatonnes. This analysis highlights that increasing energy efficiencyis the most important policy measure for reducing the cement industry's energy and emissions intensity,given the current state of the industry and the unlikelihood of significant carbon capture and storagebefore 2030. In addition, policies to reduce total cement production offer the most direct way ofreducing total energy consumption and CO2 emissions.
