This paper provides an assessment of the potential of CO2 mitigation in buildings by conducting an empirical research on the determinants of building energy-related CO2 emissions. The building sector accounts for 30%–50% of CO2 emissions and thus has significant impacts on global warming. This paper fills the research gap by investigating the economic factors that determine energy-related CO2 emissions in China's commercial and residential buildings. Based on provincial data, a three-dimensional LMDI decomposition of building energy-related CO2 emissions into four components is proposed, and includes scale, income, intensity and structure effects. The results suggest that: (i) China's building energy-related CO2 emissions are increasing rapidly; (ii) The improvement in living standards is the leading driving force of the increases in emissions, but its importance diminishes due to energy efficiency improvement and transformation to low-carbon energy structure; (iii) The evolution of China's commercial building energy-related CO2 emissions shows the features of the environmental Kuznets curve; (iv) CO2 emissions would further increase in the developed eastern regions due to large-scale migration from rural to urban areas.
