Structural emissions reduction of China's power and heating industry under the goal of “double carbon”: A perspective from input-output analysis

Abstract

Since the Chinese government put forward the "double carbon" target in 2020, emissions reduction has become the focus of the Chinese government's work. China's power and heating sector account for about 50% of China's total energy utilization. Therefore, implementing carbon emissions (CO 2 e) reduction in China's heat and power industries is an important part of China's goal to achieve "double carbon". Commencing the viewpoint of input-output investigation, the current paper uses the extended form of the input-output method, structural decomposition method, and energy utilization approach to examine the structural emission diminution of China's power and heating industry from 2007 to 2015. The outcomes show that initially from the investigation of structural aspects affecting CO 2 e of power and heating energy at the same time as the energy intensity, input, and energy composition influence played a critical function in minimizing CO 2 e in China's power and heating sector with this emission reduction effect viewing an increasing trend. Among them, the input composition influence was the key pollution diminution aspect of electric heating energy; second was the energy intensity influence, and the energy structure influence was the weakest. Second, the ultimate demand consequence was the core pouring aspect for the power and heating energy-allied growth CO 2 e with this driving effect displaying an increasing trend over time. Third, in the perspective of the supply side energy system analysis, less carbon power for instance coke oven gas, converter gas, blast furnace gas, and natural gas generally had emission reduction effect, except for raw coal, crude oil, diesel, fuel oil, and washing firewood and other high carbon energy had no obvious emission reduction effect. The research findings of the current study can provide a hypothetical analysis basis for the power heating industry to control the growth of CO 2 e from the viewpoint of input and output, and also provide an accurate path for the electric heating industry to more precisely decrease emissions from the supply side energy varieties.
