“…Cement industry provides an irreplaceable support for the operation of various downstream industries of Chinese economy (Song et al, 2016) that lead China to be the largest cement producer in the world since 1985 (Ke et al, 2013). CO 2 emissions from China's cement industry have drastically scaled up from 930 Mt in 2005 to 1597Mt in 2012 while the cement production increased at an average rate of 11% per year during the same period (Zhang et al, 2015b). Since recognizing China's cement industry will inevitably continue to generate large volume of CO 2 emissions, this industry is under close scrutiny recently.…”

a b s t r a c tTo devise low-carbon cement clinker product, in-depth knowledge about the variation mechanism of cement clinker CO 2 emissions is the prerequisite. The determinants of cement clinker CO 2 emissions in Chinese cement industry have been inquired by several researches recently. However, the impacts and abatement effect of clinker quality on cement clinker CO 2 emissions have not been identified yet. In technological sense, there lacks an integrated quantitative model that can elucidate the dynamic mechanism between cement clinker CO 2 emissions and clinker quality. To fill this gap, this paper devises a CO 2 emission accounting framework integrated with optimization model to explore the dynamic mechanism between cement clinker CO 2 emissions and clinker quality. Based on survey data of 2 typical cement clinker production lines in China, the accounting framework is validated with measured data. Through numerical simulation within this framework, a set of sensitivity analysis is conducted. The results indicate that if the target KH (lime saturation ratio) of both production lines climb from −5% to +5%, the process CO 2 emission factor will give rise to an increase of about 16.4 and 14.8 kg CO 2 /t clinker, respectively. With the same variation, the fuel CO 2 emission factors of two production lines will gain 17.2 and 13.7 kg CO 2 /t clinker, respectively. Obviously, controlled decrease of clinker quality can reduce CO 2 emission of clinker manufacturing. The results of sensitivity analysis are robust and highlight the remarkable role of clinker quality in both process and fuel emissions. Besides, the integrated framework can provide in-depth investigation into the dynamic mechanism between CO 2 emissions and the other determinants. Using this framework, cement plants or industry can develop optimal clinker quality standards on a quantitative basis to achieve low-carbon clinker.

The present paper highlights a quantitative method to maximize energy efficiency based on the minimum energy consumption and maximum quality of life from consumption behaviors. Quality of life is expressed by utility, which is a Constant Elasticity of Substitution (CES) function of demands for composite goods, car trips and public transport trips. Individual energy consumption is estimated by the demand of goods and we applied this method to Nagasaki to evaluate energy efficiency. Our results showed that 28,154 kcal of energy is needed to support the life of one individual per day in Nagasaki. Furthermore, we found that 76% of energy was used for composite goods and 24% was used for mobility goods. To achieve maximum energy efficiency, our results highlight that energy should be reduced by increasing the consumption of composite goods and public transport trips, while simultaneously decreasing the consumption of car trips. Compared to residents in urban and suburban areas, individuals in Central Business Districts (CBD) were found to have higher energy efficiency. Findings in Nagasaki suggest three policy implications: First, eco-energy consumption patterns should be encouraged to decrease energy use, while maintaining quality of life. Second, mixed land use is attributed to increased energy efficiency. Lastly, the energy efficiency of mobility could be improved though increasing the attraction of public transport.

“…The global cement industry contributes 5-7% of global anthropogenic CO 2 emissions (Wang et al, 2013). China has been the largest cement producer in the world since 1985, accounting for ~ 60% of the global cement production in 2012 (Chen et al, 2015;Edwards, 2013;Zhang et al, 2015a). In recent years, China's cement industry has skyrocketed owing to accelerating economic development and urbanization.…”
