There are many articles in the field of CO2 emission decomposition and the methods including Laspeyres index, Sample Average Division and Adaptive-Weighting Division are more scientific now, but many researchers just focused on one factor of carbon emission intensity or energy consumption intensity and lacked further decomposition. This paper presents a complex formula to calculate carbon emission, then examines the factors, including total energy consumption, energy mix, technology, inter -input, industrial structure and total industrial production, which have effects on CO2 emission from industrial energy during the period 1992~ 2005 by the decomposition method of LMDI proposed by Ang et al. The results show that the gross emission of CO2 induced by the energy consumption of manufacture in China increased rapidly during the period of 1992 -2005, especially in 2002 -2005 coherent with the economic development path. And the increase is mostly derived from the augment of total industrial production with the characteristics of heavy industrialization, low efficiency of energy consumption and the mix of primary energy with high proportion of coal. Beyond our expectation, the factors of technology (proportion of inter-input) and industrial structure do not have a big reduction of CO2 emission because of the economic development mainly driven by huge investment of infrastructure such as transportation, housing construction and primary manufacture such as steel, cement, chemistry and so on. But the quantity change of inter-input including other unaccounted factors is the primary contributor. The results indicate that accelerating technology upgrade, regulating industrial structure and energy mix, and developing CMD (Clean Development Mechanism) project are the efficient ways to reduce CO2 emissions.
