Analysis of Carbon Emission Characteristics of Transportation Industry in Hunan Under the"Dual Carbon"Background
To accelerate the realization of the"dual carbon"goal in the transportation industry in Hunan,this paper aims to establish a clear scope and boundary for carbon emission accounting to measure the carbon emissions in the transportation industry in Hunan from 2012 to 2021 based on the"bottom-up"method,and analyze the carbon emission structure of the transportation industry in Hunan,thereby providing a theoretical basis for the green and low-carbon transformation of the transportation industry in Hunan.The results indicate that:① The carbon emissions from the transportation industry in Hunan showed a rapid upward trend from 2012 to 2018,due to the adjustment of statistical standards in the freight sector and the impact of the COVID-19,the carbon emissions from 2019 to 2021 were not comparable to those before,and the average annual growth rate slowed down.② Carbon emissions from transportation industry in Hunan are mainly analyzed in 3 major sectors,sorted in descending order of carbon emissions are urban transportation,freight transport,and passenger transport,with the emission proportions in 2021 being 74.2％,20.4％,and 5.4％,respectively.③ Private vehicles,road freight and aviation passenger transport are the key emission sources of the 3 sectors.Finally,combining the research and discussion to put forward the specific and effective countermeasures and suggestions for 3 key emission sources:private vehicles,road freight and aviation passenger transport.
