With the growing threat of global climate change, energy savings and CO2 emissions reduction have become a major long-term issue faced by China. For a more scientific analysis of energy savings and emissions reduction data of China, a modified logarithmic mean Divisia index (LMDI) approach is adopted. The modifications and the theoretical model of the approach are introduced in this paper. Based on China’s economic development and energy consumption data during the 12th Five-Year-Plan period, quantitative assessment of effects of the energy savings and emissions reduction in the four key areas (namely energy conversion efficiency improvement, energy utilization efficiency improvement, primary energy mix adjustment and industrial structure adjustment) is carried out. The results and laws of energy savings and emissions reduction in the above areas during the 12th Five-Year-Plan period are summarized. Finally, combined with historical analysis and current situations, some suggestions for China’s future work in the field of energy savings and emissions reduction are proposed.
