A quantitative evaluation method based decomposition analysis and its application on the life-cycle effect of energy conservation and emission reduction

Quantitative methods calculating life-cycle control index(LCCI) in energy conservation and emissions reduction were created by results from decomposition analysis.Evaluating principle of LCCI were also put forward and applied in quantitative evaluation results from each factor contributing to energy-saving and sulfur dioxide emission reduction in different countries.Energy conservation LCCI of China during 1986~2005 was 0.6,lower than the developed countries of 0.86 in 1973~1990,and 0.75 for sulfur dioxide emission reduction LCCI of China during 1995~2005,much lower than Japan's 1.07 in 1975~1996.The reason was that contribution from technology progress and end-of-pipe(EOP) was low.Presently,more projects in technological progress and EOP should be taken for realization of pollutants reduction targets,as well as role of structural adjustment.
