Construction and Application Analysis of Carbon Emission Influence Factor Model of Energy Consumption in Mining Industry

Abstract

With the proposal of China’s “double carbon goal,” as a high energy-consuming industry, it is urgent for the mining industry to adopt a low-carbon development strategy. Therefore, in order to better provide reasonable suggestions and references for the low-carbon development of mining industry, referring to the methods and parameters of the 2006 IPCC National Greenhouse Gas Inventory Guidelines and China’s Provincial Greenhouse Gas Inventory Preparation Guidelines (Trial), a carbon emission estimation model is established to estimate the carbon emission of energy consumption of China's mining industry from 2000 to 2020. Then, using the extended Kaya identity, the influencing factors of carbon emission in mining industry are decomposed into energy carbon emission intensity, energy structure, energy intensity, industrial structure, and output value. On this basis, an LMDI model is constructed to analyze the impact of five factors on carbon emission from mining industry. The research shows that the carbon emission and carbon emission intensity of energy consumption in China’s mining industry first rise and then fall and then rise slightly. The carbon emission intensity in recent three years is about 2 tons/10000 yuan. The increase in output value is the main factor to increase carbon emission. The reduction in energy intensity is the initiative of carbon emission reduction. The current energy structure of mining industry is not conducive to carbon emission reduction.

Construction and Application of Relationship Model between Development of Mining Industry and Carbon Emission of Energy Consumption

“…e calculation process of carbon emission of energy consumption in mining industry and its subdivisions refers to the research of Wei et al [26], and the specific calculation results are shown in Table 7.…”

“…e five subsectors are abbreviated as coal sector, petroleum and natural gas sector, ferrous metal sector, nonferrous metal sector, and nonmetal sector. For the calculation method and process of carbon emissions of mining industry and subindustries involved in this study, Wei's et al's research is referred [26].…”

Carbon Emission Prediction Model for the Underground Mining Stage of Metal Mines

“…The carbon emissions related to trucking work and were calculated by considering the carbon emission factors of the road and the distance as determined by the best-route analysis based on GIS. Lili Wei et al (2021) [13] established a carbon emission estimation model to estimate the carbon emissions of the energy consumption of China's mining industry from 2000 to 2020, referring to the methods and parameters of the 2006 IPCC National Greenhouse Gas Inventory Guidelines. Then, using the extended Kaya identity and the LMDI model, analyzed the influencing factors of carbon emissions in the mining industry, including energy carbon emission intensity, energy structure, energy intensity, industrial structure, and output value.…”
