Abstract: The power industry faces big challenges of energy saving and emission reduction while it supplies energy for the fast development of the economy. The paper conducts an empirical study on key factors of carbon emission intensity of the power industry. A factor decomposition model is established with the logarithmic mean divisia index to analyze the impacts of some factors such as the house service rate, the power generation structure, the gross coal consumption rate and the line losses on carbon emission intensity. The empirical results show that the reduction of gross coal consumption rate in positive direction is the main contributor to the accumulative reduction of carbon emission intensity, while the primary cause for the short-term changes of carbon emission intensity is the power generation structure and the other causes are, the gross coal consumption rate, the line losses and the house service rate in descending order.

Key words: carbon emission, emission reduction, decomposition analysis, power industry
