Two general methods for decomposing energy-induced carbon dioxide emissions in the manufacturing industry are presented, based on the Divisia index approach. Changes in the aggregate carbon dioxide intensity are distributed among 4 causal factors, namely fuel carbon dioxide emission coefficients, manufacturing production structure, fuel shares and sectoral energy intensities. The basic features of the methodology and the information it provides are described. Then four specific methods are used to decompose changes in the aggregate carbon dioxide intensities in China, South Korea and Taiwan. The results obtained show that the intensity effect has the largest impact on the changes in the aggregate carbon dioxide intensities in the 3 economies.
