*2.4. Data Input*

China's energy data for 2015 are obtained and calculated from China's official statistics sources such as China Energy Statistical Yearbook 2016 [25], The 11th Five-Year Plan for Energy Development [14], The 12th Five-Year Plan for Energy Development [18], and a series of reports such as Energy Data of China 2016 [26], and Survey Analysis of Lighting Power Consumption in China [27]. The China's energy data in 2005 are from Ma et al. [6]. The carbon emission factors are calculated from General Principles for Calculation of the Comprehensive Energy Consumption [22], China Guidelines [23] and IPCC Guidelines [24]. Some other data are from authors' calculation. Detailed data sources and processing are shown in Appendix D, and some key data in the processing are listed in Tables A3–A9.
