Rapid urbanization has significant effects on China’s CO2 emissions and contributes to climate change. Using a cross–city panel of 64 cities from four large urban agglomerations in China over 2006–2013, we estimate urban household residential energy-related CO2 emissions. We then apply fixed effects two-stage least squares (2SLS) to explore the relationship between urbanization and residential CO2 emissions, using an augmented Stochastic Impacts by Regression on Population, Affluence and Technology (STIRPAT) model. The results show that the average amount of residential CO2 emissions in these four agglomerations has a strong increasing trend over 2006–2013, rising from 2.85×106 to 5.67×106 tons. Those with municipality and capital city status emit more residential CO2 emissions. A rising urban population share significantly influences residential CO2 emissions, as does population scale, GDP per capita, urban compactness and the comprehensive level of urbanization. Urban population share has positive effects on residential CO2 emissions even pasting the demarcation point (75%) in China’s urban agglomerations. GDP growth has negative effects on residential CO2 emissions. Finally, policy options are provided for promoting low-carbon development and enhancing green technology innovations that curb urban residential energy-related CO2 emissions in the process of China’s eco-urbanization.
