Carbon footprint and embodied carbon transfer of the city clusters in the Yellow River basin
This study constructed a 2017 environmental expansion MRIO model about 71 cities in the national city clusters of the Yellow River Basin.The carbon footprint of three sources,including fossil energy combustion,coal mining escape,and agricultural non-energy emission was evaluated.The embodied carbon transfer between city clusters and between cities and sectors within the city cluster was analyzed.The results showed that:The total carbon footprint of 5 city clusters was about 2478.34 Mt fossil energy combustion contributed 86.42％,which was the main source of the carbon footprint.Coal mining escape and agriculture non-energy emission can't be neglected,contributing 10.09％and 3.49％respectively."Coal mining and washing","metal smelting and pressing",and"electricity and heating power production and supply"were the key sector for carbon footprint,accounting for 62.67％and 36.77％of the total carbon footprint from the perspective of production and consumption respectively."Metal smelting and pressing",and"electricity and heating power production and supply"were the key export sectors for embodied carbon,accounting for 51.43％of the embodied carbon transfer within city cluster."Wholesale,retail trade,accommodation and catering services"accounting 26.79％was the key import sector for embodied carbon."Metal smelting and pressing"→"Wholesale,retail trade,accommodation and catering services"was the main transfer path for embodied carbon.The key cities for carbon footprint or export cities were mostly with a high proportion of resource-consuming and heavy chemical industries,such as Ordos,Binzhou.The key import cities consumed a lot of products from other cities to maintain development,such as Qingdao,Hohhot.The carbon footprint was mainly concentrated in Jiziwan,Shandong Peninsula and Zhongyuan.The combined carbon footprint accounted for 85.89％and 85.02％from the perspective of production and consumption respectively.Jiziwan was the city cluster which exported the most embodied carbon,accounting for about 40.68％of the embodied carbon transfer between city clusters.Zhongyuan accounting for 42.24％was the city cluster which imported the most embodied carbon.The results can provide the city clusters in the Yellow River Basin more reasonable basis for the formulation and improvement of carbon control policies and carbon reduction measures.
