Changes And Driving Forces Of Consumption-based Carbon Emissions In Shanghai

Excessive emissions of carbon dioxide and other greenhouse gases are the main causes of global warming.It leads to several extreme weather problems,such as temperature rise,glaciers melting,sea levels rising,persistent drought and so on,which are threatening the survival and development of mankind.As a responsible big country,China has actively undertaken reasonable emission reduction obligations in the international community and made an important contribution to global carbon emission reduction.It is an important basis to carry out the work of carbon emission reduction to conduct scientific and reasonable accounting of regional carbon emissions so as to effectively divide the carbon emission responsibility that should be taken.At present,the international accounting method and responsibility division of carbon emissions are not reasonable enough,resulting in a large number of "carbon leakage" problems in international trade.As the largest economic center city in China and a world-renowned port city,the progress of Shanghai's own emission reduction work is directly related to the direction and effect of China's carbon emission reduction work.This paper accounts for Shanghai's consumption carbon emissions from the perspective of final demand,takes the carbon transfer caused by trade into consideration,and conducts a structural decomposition analysis of Shanghai's consumption carbon emissions to further explore its driving factors,in order to provide theoretical reference for Shanghai to build a low-carbon city.In this paper,the multi-scale input-output method and structural decomposition analysis method are used to analyze and study the carbon emission in Shanghai.The main research results are as follows :(1)Shanghai has transferred a large amount of carbon emissions to other regions,so Shanghai should assume more responsibility for carbon emission reduction;as for industrial sectors,the energy sector of Shanghai not only produces a large direct carbon emission,but also involves more carbon emission transfer issues.(2)in terms of the final demand structure of Shanghai,urban residents' consumption leads to the most carbon emissions from consumption,while rural residents' consumption leads to the fastest growth.(3)based on the research of the Shanghai with the domestic and international carbon trade volume,found that the Shanghai contact with domestic and international carbon emissions increasing at the same time,the imbalance of carbon transfer at home and abroad are moderate after the first increased,and as a transit hub in Shanghai will be part of the foreign carbon emissions is transferred to other parts of China;(4)by decomposing the change of the carbon footprint of Shanghai into eight social and economic factors,the study found that in 2002-2007,the rapid growth of the population in Shanghai and driven by consumption level rise final demand growth to become the main factors,the carbon footprint,increase the change of production technology play a key role in reducing carbon footprint in Shanghai,in 2007-2012,domestic to change is the primary factor to the rise in Shanghai carbon footprint,the change of production technology and reduce the carbon footprint of the main driving force.Based on the results of empirical analysis,this paper puts forward corresponding policy Suggestions from the aspects of adjusting energy structure and building modern industries,strengthening technological innovation and transforming government functions,coordinating urban and rural economy and environment,and exploring a more reasonable carbon emission liability mechanism.
