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.
