CO2 Emissions from China’s Lime Industry (Shan Y., Z. Liu, D. Guan, 2015, Applied Energy)
China is now the world’s leading energy consumer and CO2 emitter; therefore, precise quantification of the CO2 emissions that occur in China is of serious concern. Although most studies focus on CO2 emissions from fossil fuel combustion and cement production, the emissions from lime production is not well researched. Lime production is the second largest source of carbon emissions from industrial processes after cement production. This is the first study to present an analysis of CO2 emissions from China’s lime production from 2001 to 2012, and we have estimated the process emissions (scope 1 direct emissions caused by the process), fossil fuel combustion emissions (scope 1 direct emissions caused by fossil fuel combustion), and scope 2 indirect emissions (CO2 emissions caused by electricity consumption) from China’s lime industry. The estimations show that the process emissions increased rapidly from 88.79 million tonnes to 141.72 million tonnes from 2001 to 2012. In 2012, the scope 1 emissions from fossil fuel combustion were 56.55 million tonnes, whereas the scope 2 indirect emissions were 4.42 million tonnes. Additionally, we analysed the uncertainty of our estimations, and our analysis shows that the relative uncertainty of the emission factors and activities data falls between 2.83% and 3.34%.

CO2 Emissions from China’s cement Industry (Shan Y., et al. 2018, Journal of Industrial Ecology)
In order to fight against the climate change, China has set a series of emission reduction policies for super-emitting sectors. The cement industry is the major source of process-related emissions, and more attention should be paid to this industry. This study calculates the process-related, direct fossil fuel- and indirect electricity-related emissions from China’s cement industry. The study finds that China’s cement-related emissions peaked in 2014. The emissions are, for the first time, divided into seven parts based on the cement used in different new-building types. The provincial emission analysis finds that developed provinces outsourced their cement capacities to less-developed regions. This study then employs index decomposition analysis to explore the drivers of changes in China’s cement-related emissions. The results show that economic growth was the primary driver of emission growth, while emission intensity and efficiency were two offsetting factors. The changes in the construction industry’s structure and improvement in efficiency were the two major drivers that contributed to the decreased emissions since 2014.
