This paper aims to explore the change of CO2 intensity in China at both national and provincial levels. To serve this purpose, we introduce a decomposition model which integrates the merits of index decomposition analysis and production-theoretical decomposition analysis. Based on the decomposition, we also estimate the potential reduction of CO2 intensity for China and its provinces. Using a panel data set including China’s 30 provinces during the period of 2006–2012, the empirical analysis is conducted and meaningful results are obtained. First, the potential energy intensity change was the dominant driving factor for the decrease of CO2 intensity, which contributed to a total reduction of 19.8%. Second, the energy efficiency change and the CO2 emission factor change also play positive roles in the CO2 intensity reduction for most provinces. Third, provinces in the western area generally showed a relatively large potential reduction in CO2 intensity, while those in the eastern area only demonstrated a small reduction. View Full-Text
