Factors affecting CO2 intensities of power sector in Asia: A Divisia decomposition analysis

This paper analyses the evolution of CO2 intensity of the electricity sector in 12 selected Asian countries during the period 1980-90. The roles of changes in generation mix and fuel intensity in CO2 intensity changes during the period have been examined using Divisia index decomposition approach. A key finding of this study is that power sector CO2 intensities of most Asian countries were mainly influenced by changes in fuel intensities during 1980-90.
