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

Abstract

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.
