Analysis of CO2 mitigation policies in the Chinese cement industry

  • The cement industry is one of the major energy consuming and CO2 emitting sectors in China. In 2010, 1,868 million tons of cement has been produced, which accounted for 56.1% of the world's total cement production. The 11th Five-Year Plan (FYP) (2006-2010) included policy measures for CO2 emission abatement in cement production. Based on the main governmental framework of CO2 mitigation policies at national level in the cement sector, key policies and technologies used during this period are identified and their effects on CO2 reduction are assessed. This paper calculates the reduction of CO2 emissions related to four main policies and technologies for efficient cement production in the 11th and the 12th FYP (2011-2015) with 2005 as aThe cement industry is one of the major energy consuming and CO2 emitting sectors in China. In 2010, 1,868 million tons of cement has been produced, which accounted for 56.1% of the world's total cement production. The 11th Five-Year Plan (FYP) (2006-2010) included policy measures for CO2 emission abatement in cement production. Based on the main governmental framework of CO2 mitigation policies at national level in the cement sector, key policies and technologies used during this period are identified and their effects on CO2 reduction are assessed. This paper calculates the reduction of CO2 emissions related to four main policies and technologies for efficient cement production in the 11th and the 12th FYP (2011-2015) with 2005 as a reference year. These are waste heat recovery, closing outdated facilities, substitution for clinker production and other technologies aiming to increase energy efficiency. Due to these measures, we estimate that a total CO2 emission reduction during the 11th FYP of 397 million tonnes could be saved, which is considerably different to 185.75 million tonnes estimated by Zeng (2008) and 303 million tonnes by the NDRC by using different calculation methods. Of the four technologies, the 4th group of energy efficiency increasing techniques was the most important policy and avoided the largest amount of CO2 emissions. Previous energy intensity reduction was mainly due to the outdated production closing and energy efficiency improving. Based on the assessment of technology performance, it appears that there is still a large emission reduction potential in cement production processes. The paper calculates this potential for the 12th FYP period (2011-2015) based on these four identified policy measures. The result is compared to the Chinese government targets in the 12th FYP and promising future CO2 mitigation policies and technologies are proposed, such as the use of alternative energy.show moreshow less
