The Potential and Cost Analysis of Emission Reduction in China’s Cement Sector

Abstract:

The cement sector emission occupies 5% of world emissions caused by human activities. Especially, China’s cement production accounted for 50% of the world’s output, which ranked the first for continuous 25 years. The total production in 2010 was 1.882 billion tons. The cement sector, which is characterized of high yield, small-scale enterprises, low technology development level and poor product structure, is one of the biggest energy consumers and emitters in China. Therefore, the energy saving and emission reduction in cement sector is not only the essential measure and basic content for coping with climate change, but also the guarantee for the sustainable development. Plenty of basic research, including spot investigation and data collection, was carried out in this paper. After the identification of 18 different kinds of energy saving technologies and emission reductions, a baseline as daily 5000 tons of a production line was set in this paper. The emission reduction potential and cost are quantitatively analyzed by estimating the marginal abatement costs. Hence, the marginal abatement cost curve of energy saving and emission reduction technology was obtained. With the abatement costs ranking from low to high, the key emission reduction technology can be concluded as energy efficiency, energy alternatives, blended cement and CCS technology. According to the status of domestic energy-saving technology as well as support policies, we finally proposed relevant measures and policy suggestions.
