Abstract:

The urban energy consumption carbon footprint is so important for the developing low-carbon economy. Based on the STIRPAT model and the ridge regression method, this article analyzes the trend of energy consumption carbon footprint of the metropolitan district of Changchun and Jilin during the period of 1999 to 2008. In it, the total energy consumption in the metropolitan district of Chang and Jilin is calculated, and the relationship between economic development and the energy consumption carbon footprint is analyzed. The carbon footprint per capita indicates a tendency from decline to rise, and the decoupling index reflects the state of relative decoupling between economic growth and energy consumption carbon footprint. Both are employed in this study. The results are follows. 1) The energy consumption carbon footprint has fluctances in the metropolitan district of Changchun and Jilin. The carbon footprint per capita was low from 1999 to 2002, and increased from 2002 to 2008. 2) Changchun and Jilin have different pillar industries, which has great disparities in the energy consumption. For the energy consumption structure, there is a significant positive correlation between the energy consumption carbon footprint of coal and the oil index, and both of them are notable increase. 3) The proportion of productivity and living carbon footprint increases, and the output value of ernergy consuption carbon footprint indicated a fluctuating situation in the metropolitan district of Changchun and Jilin. 3) There is significant positive correlation between energy consumption carbon footprint and economic development, progress of knowledge, and urbanization. Of all influencing facotrs, the economic development is the dominat, but the later two work less. 4) The decoupling index of economic growth and energy consumption carbon footprint fluctuates within the stats of relative decoupling and in re-coupling. According to the situatin of of energy consumption carbon footprint of the metropolitan district of Changchun and Jilin, a set of governmental countermeasures are necessary. 1) The moderate efforts should be made to revise birth control targets; 2) The civic investment should be increased to advocate a low-carbon in metropolitan district of Changchun and Jilin; 3) The energy saving technologies should be adopted in this region; 4) The strategic planning and policy making for the long-term reduction of energy consumption should consider. The article improves the understanding of the impact of urban economic development on urban energy consumption carbon footprint, and will be a support in the plan-making of ernergy consuption in the economic development of old industy base.
