Tianjin CO2 Emissions: The Status and Empirical Analysis of Factor Decomposition

Under the background of the international and domestic attention focusing on the research on CO2 emissions, Tianjin's theoretical literature in the study of CO2 emissions measurement and mechanisms is still scarce. We analyzed Tianjin's total CO2 emissions, carbon intensity, per person CO2 emission and three major industries' variation in CO2 emissions from 1996 to 2008, and compare the three departments' terminal energy use of total CO2 emissions. Adopting LMDI decomposition method, we set up a decomposition model of Tianjin incremental factors in CO2 emissions and quantitatively analyzed influences of CO2 emission increment which cased by economic scale, industrial structure, technical progress and energy consumption structure during in 1996-2008. Through the research, we found that economic scale is a positive factor; technical progress is negative factor; the influence of adjustment of industrial structure and energy consumption structure is relatively weak.
