A Life Cycle Modeling Framework for Greenhouse Gas Emissions of Cement Industry

How to deal with global climate change and alleviate the pressure of carbon mitigation has been an urgent problem for the current social economic development. Cement is one of the three main building materials, which provides important support for other related industrials. Concerning the emission characteristics during the production procedure, it has a vital significance to analyze the current emission situation and forecast its emission trends. However, recent research mainly focused on static analysis of the direct emissions, which is not conductive to decision makers to grasp the emission potential in cement industry. This study presented a simulation model to depict the future emission trends based on system dynamics, and aimed to put up with different optimization scenarios in view of current energy conservation and emission reduction targets. The results may help decision makers identify the current emission situation and predict precisely the emission trend, thus realizing the emissions targets in view of the whole process of the cement industry in China.
