The Study Of The Carbon Emission Of Passenger Transport In Typical Cities

From the first climate conference in 1979 to signed by the Paris Agreement in 2015,the rise in CO2 concentration led to global warming consensus,climate issues have become the focus of global attention.With the rapid growth of economic,people gradually depend on transportation,therefore,the transport sector's energy consumption has shown an accelerated trend,and become one of the most resource-intensive sectors,the resulting carbon dioxide accounts for global emissions 30% of the total.Therefore,the development of low-carbon transport will be the future direction of China's urban traffic development.This paper selects seven typical cities in Beijing,Shanghai,Guangzhou,Chengdu,Xi'an,Taiyuan and Urumqi,and makes clear the scope of the study to determine the passenger traffic as the object of study.Based on the data from 2000 to 2014,this paper reviews the typical urban socio-Passenger traffic development,calculate and study the passenger transport carbon emissions and its changes in the law.1.The total amount of carbon transportation in the typical urban passenger transport traffic respectively is16.8786 million tons,6.7924 million tons,7.5149 million tons,9.6423 million tons,6.06 million tons,3.1830 tons,2.0179 million tons,by the end of 2014,and passenger transport carbon emissions and GDP per capita GDP significant correlation and exceeded 0.9,indicating that the level of economic development and passenger transport CO2 emissions were positively correlated.2.The per capita carbon emissions of each typical city showed a significant increase trend.Which Beijing has the highest per capita carbon emissions,Shanghai is the lowest.Per capita carbon emissions and the total change is basically the same.By the end of 2014,the average difference in carbon emissions per capita from typical cities was only 70 kg CO2/person,and the economic aggregate and growth rate were important factors affecting per capita traffic carbon emissions.GDP emissions of carbon monoxide perunit of GDP in Chengdu and Xi'an remained stable.The carbon emissions per unit of GDP in Taiyuan and Urumqi were increasing in stages.With the increase in per capita income levels,the intensity of carbon emissions will be reduced.4.From the structural point of view,the typical urban passenger transport carbon emissions in the order of: private cars,buses,taxis,and the number of private cars due to the exponential growth led to their emissions accounted for more than 70% of the passenger traffic The largest source of carbon emissions.The typical urban passenger transport mode of carbon emissions are growing,but the taxi and bus carbon emissions accounted for a continuous decline.Finally,the countermeasures are put forward for the development of passenger transport in China.
