Anthropogenic Carbon Emission Accounting And Analysis Of Its Influencing Factors Of Nanning City

Carbon emission reduction for provinces and cities were put on the agenda in China since Chinese government made a commitment to cut down intensity of carbon dioxide emission by40%-45%until2020compared to2005; In order to plan and conduct carbon emission reduction legitimately, to find out the total amount of carbon emission, structural features and its distribution is essential. In this study, anthropogenic carbon emission sources of Nanning were divided into seven sectors, which include power consumption of the Primary Industrial, Industrial energy consumption, power consumption of the Tertiary Industry, energy consumption of Transportation, waste landfill, Industrial process, residents living energy consumption; Then anthropogenic carbon emission accounting methodology for Nanning was established and its emission characteristics, distribution and influencing factors were analyzed, the results are as follows:Firstly, sector of Industrial energy consumption is the first large one of Nanning carbon emission, increase of energy consumption lead to its continued growth while its CO2emission intensity showed a decrease trend in general; Non-metallic mineral products industry, agro-food processing industry, chemical materials and chemical products manufacturing, paper and paper products industry are main CO2emission industries; since CO2emission intensity of non-metallic mineral products industry always ranks first among industries, CO2emission intensity of paper and paper products industry, agro-food processing industry and Ferrous metal smelting and rolling processing industry show a rising trend, they should be inspected and administrated preferentially. Industrial process sector is the second large one, of which the main factor is the production of cement; The third large sector is energy consumption of transportation sector, per capital GDP is its most closely related factor. The fourth to seventh sectors are followed by residents living energy consumption, power consumption of the Tertiary Industry, waste landfill and power consumption of the Primary Industrial one. In aspects of carbon emission out from energy consumption, due to disparity in urban development and living standards and economic structure, total anthropogenic carbon emission, per capital carbon emission and Geographical intensity of Nanning city are at a low level and Economic intensity approximately the same when compared to domestic developed eastern cities’ones.Secondly, total CO2emission, CO2emission out from each sector, per capital CO2emission and Geographical intensity of Urban districts are higher and Economic intensity is lower than of each county; Affected by multiple factors, Total CO2emission and emission out from each sector of each county all show fluctuant trends while their rising potentials are both higher than of Urban districts; There is a positive correlation between CO2emission and its area of construction land for each county.Finally, in2003-2012decoupling relationship between anthropogenic CO2emission and per capital GDP is weak decoupling, results of driving factors analysis for Nanning CO2emission by using extended STIRPAT model is as follows:Driving factors of Nanning CO2emission ranked according to the influencing contribution is followed by population, sum of automobiles, Industrial added value proportion of GDP, per capital GDP and Intensity of CO2emission; the relationship between per capital GDP and carbon emission is not as the EKC suggested; impact of industrial development led by technological progress on carbon emission reduction isn’t large enough.In order to achieve a low-carbon economy efficiently for Nanning city under the background of carbon emission rising, great efforts should be attached to eliminate backward production capacity and to increase the promotion and application of clean energy; Industrial transformation and upgrading should be conducted to change traditional industrial growth, which mainly depends on resource consuming, as well as allocation of carbon emission reduction on both carbon emission sectors and counties should be conducted scientifically and rationally.
