Evaluation of Green Low-Carbon Level and Carbon Efficiency at Chinese Provincial Level Based on"Full Carbon"Accounting
This paper breaks through the limitations of the"traditional carbon"accounting which mainly focuses on the carbon emissions from energy consumption,and includes waste emissions,biomass resource consumption,net electricity input and forest carbon sequestration into the evaluation scope.By using the natural energy link between the above indicators,the"Full Carbon"accounting is carried out in China's provinces,and then the direct carbon efficiency evaluation based on carbon footprint and the total factor carbon efficiency evaluation based on DEA-BCC model are carried out.The results show that:(1)From 2016 to 2020,the direct carbon efficiency of most provinces in China has increased significantly,but the total factor carbon efficiency has decreased.In the context of the"carbon peaking and carbon neutrality" compared with other means of production,the carbon environmental capacity is increasingly scarce,so the phenomenon of the decline of the total factor carbon efficiency should be paid attention to.(2)Under the two accounting systems of"Full Carbon"and"traditional carbon",the evaluation results of direct carbon efficiency and total factor carbon efficiency are different,especially in 2020.Pollution reduction and carbon reduction are the same root and source problems,and energy and power security is an important guarantee for economic development.In this context,the evaluation results of"Full Carbon"efficiency are more interpretable,which can more comprehensively reflect the low carbon level and development potential of each province,and provide a new idea for clarifying the responsibility of carbon emission reduction between regions and making comprehensive carbon decisions.
