Study on energy consumption and CO2 emissions of China´s cement industry

The cement industry is an energy intensive industry, also the one of main CO₂ emissions source. China is the largest producer and consumer of cement in the world. In 2009, the cement production in China reached 1.63 billion tons, accounting more than 50% of total cement production in the world. However, most of the cement was produced from relatively energy-inefficient and highly-polluting vertical shaft kilns. In this paper, the characteristics of production and energy consumption for China´s cement industry were analyzed. The CO₂ emissions from the cement industry were calculated, compared with Japan, and the characteristics of China´s CO₂ emissions were analyzed.
