Abstract
This paper estimates and analyzes CO2 emissions from energy use in Beijing and Shanghai and compares them with Tokyo and Seoul. The contributions of selected driving factors in total and sectoral CO2 emissions are investigated by factor decomposition method. In rapidly industrializing Beijing and Shanghai, income effect was found primarily responsible for increasing emissions while energy intensity effect for decreasing emissions. In transportation sector, vehicle population effect was responsible for the majority of CO2 emissions. The structures of factors in transportation, residential and commercial sectors are different in each city and time, owing to each city's distinguish features. Especially in Beijing and Shanghai the behavior of such factors are relatively unstable.
