Research on the Driving Factors of Urban Electricity-Related Carbon Emissions Based on LMDI

The electrification of energy consumption is the key to achieving the targets of carbon peaking and carbon neutrality. In order to study the main driving factors of electricity-related carbon emissions, a data acquisition and cleaning method adapted to the comparative accounting of carbon dioxide emissions from city-level electricity consumption in China is proposed. An extended LMDI model of urban electricity-related carbon emissions is proposed that comprehensively considers key factors such as population, economic output, industrial structure, power consumption intensity, and power consumption structure. Taking Nantong City as an example, the electricity-related carbon emissions from 2010 to 2020 were calculated, and the impact of each factors on the growth of electricity-related carbon emissions was quantitatively analyzed. The main conclusions are as follows: Firstly, the utilization of clean and low-carbon energy can effectively reduce electricity-related carbon emissions; Secondly, the impact mechanisms of various factors on the changes in electricity-related carbon emissions are not consistent in different stages; Thirdly, economic output and population size are the main contributors to the increase of electricity-related carbon emissions, and the power structure is the main contributor to the suppression of electricity-related carbon emissions.
