英文摘要	Cement industry is a large emitter of carbon dioxide (CO 2 ), taking up 5–8% of anthropogenic CO 2 emissions. China is the largest developing country in the world. With the fast urbanization rate, economic growth and rapid development of industry, China's cement production is soaring year by year. Also, cement CO 2 emissions increased year by year and aroused the rising attention. However, the historical province- and nation-level cement production situations, driving forces of cement output and/or demand based on rapid economic growth and urbanization rate, the peak of cement consumption and China's cement demand projection and CO 2 emissions through 2030 when China should fulfill the international commitments were not clear. The present study summarized the characteristics of China's cement production and CO 2 emissions during 2001–2015, projected cement CO 2 emission scenarios based on diffusion of alternative materials and technical innovation toward 2030. The following results were summarized, clinker- and cement- CO 2 emission factors (EFs) were declining year by year with the technical innovation. CO 2 emissions increased with the increase of cement output year by year. The discrepancies of CO 2 emissions from different researches were becoming large year by year, and the biggest difference of CO 2 emissions reached 49% in 2015. Accordingly, we recommended active EFs for the calculation of cement CO 2 emissions. Cement production situation varies greatly with province, as manifested in unbalanced NSP technology and clinker-to-cement ratio, and energy consumption, which was primarily attributed to the unbalanced resource reserves and economic development. There is still sufficient room for CO 2 reduction in China's cement industry, and the use of alternative material was better than technical innovation in such reduction. The optimal emissions in 2030 will be 1490 Mt CO 2 . And China's cement consumption will be stable in 2030, cumulative cement consumption per capita will be peaked at 23394 kg, and UR will reach 70.1%. © 2018 Elsevier B.V.
