Reduce carbon emissions efficiently: The influencing factors and decoupling relationships of carbon emission from high-energy consumption and high-emission industries in China

Abstract

High-energy consumption and high-emission industries contribute a lot to economic development, but their carbon emissions are also huge. In order to achieve the dual-carbon target as early as possible, it is necessary to reduce the carbon emissions of high-energy consumption and high-emission industries. This paper selected five representative factors (population, per capita gross domestic product (GDP), energy intensity, energy structure and carbon emission coefficient) and adopted the logarithmic mean divisia index (LMDI) method to decompose the driving factors of carbon emissions. Therefore, this paper uses Tapio decoupling model to analyze the decoupling relationship between the two factors with the greatest impact on carbon emissions and carbon emissions. The results show that: (i) There is a good decoupling between high-energy consumption and high-emission industries and per capita GDP, and the impact of per capita GDP on carbon emissions will gradually decrease in the future; (ii) The decoupling relationship between carbon emissions and energy intensity is poor. For some industries, the reduction of energy intensity can help reduce carbon emissions. Finally, this paper puts forward some suggestions to promote carbon emission reduction. This paper provides theoretical support for studying how to reduce carbon emissions and formulate relevant emission reduction policies in the high-energy consumption and high-emission industries.

Progress in Green and Low-carbon Technologies development of Building Ceramics Industry

“…These two stages account for approximately 95% of the total energy consumption in the overall production process. Moreover, the carbon emissions from the product manufacturing process constitute more than 80% of the complete life cycle of ceramic tiles in the field of building ceramics [19] . To achieve carbon emission reductions, manufacturing process optimization techniques employ measures such as equipment improvements and technological innovations to mitigate the thermal energy (coal) and electricity consumption in ceramic tile production.…”

Can Government Environmental Attention Improve Corporate Carbon Emission Reduction Performance?—Evidence from China A-Share Listed Companies with High-Energy-Consumption

“…This situation persists as high-energy-consuming enterprises excessively rely on carbon energy, exhibit a relatively lagging level of production technology, and possess low production process efficiency. These factors exacerbate energy over-consumption, presenting a formidable challenge for current carbon reduction efforts [12]. As major contributors to greenhouse gas emissions, high-energy-consuming enterprises should be a focal point for carbon emissions management.…”

Prediction of agricultural carbon emissions in China based on a GA-ELM model

“…Specifically, the first is about the calculation of agricultural carbon emissions. Most scholars use the emission coefficient method (Guo et al, 2022a), agricultural ecosystem model (Zhao et al, 2019;Sun et al, 2023), methane emission model of paddy field (Wang et al, 2018), and regional nitrogen cycle model (Mao et al, 2018) to measure and analyze agricultural carbon emissions in different regions. Among them, it has become the mainstream practice to modify agricultural carbon emission sources and related emission coefficients on the basis of the emission coefficient method (Liu et al, 2013;Wójcik-Gront and Gront, 2014;Ghosh, 2018;Gao et al, 2023).…”
