“…It is a typical metal chemical production enterprise with high pollution and high emission. Given the complexity and diversity of the chemical industry, to fully consider GHG emission sources, emission boundaries should be determined before calculating GHG emissions from chemical enterprises [5]. "Greenhouse Gas Emission Accounting and Reporting Requirements Part 10: Chemical Production Enterprises" [42] is a GHG accounting methodology guide for the chemical industry, which requires accounting for emissions from CO 2 and N 2 O in the chemical industry.…”

“…It is very important to classify and analyze CO 2 emissions. In previous estimates of carbon emissions, it is mostly the fuel combustion emissions and indirect emissions that were considered [5]. In this study, we discussed not only direct emissions from fuel combustion caused by fossil energy consumption but also process emissions caused by carbonates and indirect emissions from electricity and heat.…”

“…The growing energy demand of the Chinese chemical industry has exacerbated carbon emissions [5]. Therefore, based on the above-mentioned studies, we should explore new policies and suggestions to reduce the carbon emissions of metal chemical enterprises in more depth in order to reduce their negative impact on the environment.…”

“…In this context, in September 2020, China proposed a "double carbon" target, aiming to achieve "carbon peaking" by 2030 and "carbon neutrality" by 2060 [4]. China's chemical industry is booming as a result of its rapid economic growth, and greenhouse gas emissions (GHG) will further rise in the near future [5]. The chemical industry is closely related to human life, including more than 95% of manufactured products [6].…”

“…Jiang et al [41] decomposed GHG emissions into six driving factors and showed that the proposed method achieved a perfect decomposition. Previous research has found that LMDI is suitable for exploring the driving factors of GHG emissions in the chemical industry and can provide appropriate mitigation measures [5]. However, related studies on enterprises are still in the early stage.…”

The chemical industry is a typical high-carbon emitting industry, and achieving the goal of net zero emissions by 2050 is challenging. Therefore, metal chemical enterprises have to explore a special path of low-carbon development. This article conducted a case study on a Chinese metal chemical production enterprise with a processing scale of 28,000 t/year. Starting from the analysis of energy consumption carbon emissions, this article used available statistical data at the enterprise level to build a carbon emission estimation model for the enterprise combining different emission categories. Moreover, we also calculated the carbon emissions and carbon emission intensity of the enterprise from 2014 to 2022. Further quantitative analyses on the impact of production scale, energy efficiency, energy structure, and emission coefficient on carbon increment were also conducted using a logarithmic mean divisia index (LMDI) model. The results showed that the reduction in carbon emissions of the enterprise during the research period was due to the improvement of energy efficiency, while the production scale and energy structure served as important driving factors. Based on the results, this article proposes some policy suggestions on the future direction and focus of the enterprise’s carbon reduction work.

Renewable energy integration and operational optimization are crucial in energy sustainability and decarbonization, especially for industrial steam power systems (SPS). This study establishes an SPS superstructure that integrates wind, solar, and biomass energy. A mixed‐integer nonlinear programming (MINLP) model is developed to determine an optimal retrofit strategy that minimizes the life cycle cost, which includes carbon emission cost and energy cost. To solve this high‐dimensional complex optimization problem, a multistage strategy fusion differential evolution algorithm with dynamic partitioning of the SVM feasible domain (SVM‐MS‐DE) is developed. The results from the optimal strategy demonstrate a 9.02% reduction in the system's total cost and a 9.64% decrease in carbon emission through the incorporation of wind and solar energy. Additionally, the sensitivity analysis on biomass ratio, carbon emission price, energy demand, and carbon emission limits reveal that the region can contribute significantly to renewable energy initiatives. Several recommended policies are provided to encourage enterprises to move towards sustainable development.
