Research on carbon emissions of production-consumption sectors under the background of "Double Carbon" Take Beijing as an example

Abstract

With the development of the Green and Low-carbon, Beijing has set a model for other provinces and cities in carbon emissions reduction, and it will help achieve the goal of carbon peaking rapidly. This paper studies various influencing factors of carbon emissions from both production and consumption by improving the Kaya identity. Through analyzing productive and consumptive CO2 emissions of Beijing with LMDI technology, this paper finds that: (1) For the production sectors in Beijing, the total carbon emissions exhibited a downward trend, and the energy intensity factor was the foremost factor to restrain the increase of carbon emissions, while the restraining effects of energy structure factors and industrial structure factors were limited, and the total production promoted emissions to increase significantly. (2) For the living sectors in Beijing, the total carbon emissions first increased and then decreased, and the urban and rural structural factor played a weak inhibitory role in the increase of CO2. The population and energy intensity were significantly promoted the increase of it. Therefore, this paper proposes to continue to adjust the structure of industry and urban, develop clear energy and make full use of energy, so as to realize the "dual-carbon" goal earlier.
