Abstract
Balancing various objectives and navigating uncertainties, reducing CO2 emissions and enhancing energy efficiency in industry presents a complex challenge. While previous studies primarily focused on conventional optimization methods, this research introduces an innovative approach: a multi-criteria optimization framework tailored to address uncertainties. The primary objective is to optimize energy consumption, minimize emissions, and improve cost efficiency simultaneously within the petrochemical industry. To effectively manage uncertain variables, this study integrates decision-making simulations and expert insights through a hybrid methodology to yield optimal outcomes. Employing three distinct preference categories, the model formulates comprehensive decision-making strategies. Empirical findings underscore the model’s efficacy in reducing CO2 emissions, bridging crucial gaps in existing research, and advocating sustainable practices in the sector. Departing from conventional methodologies, this research leverages advanced decision-making techniques adept at handling uncertainty. The framework identifies pivotal emission sources and advocates economically viable reduction strategies. Its adaptability enriches our comprehension of emission challenges by considering diverse factors and expert perspectives. Professional assessments affirm the model’s success and propose a Coding-Based Prototype as a strategic tool for addressing uncertainties. These results underscore the imperative for policy reforms, such as embracing carbon capture technologies, to bolster global sustainability and foster enduring growth in the industrial domain.
1 Introduction
The emission of carbon and other greenhouse gases is a critical global issue, significantly affecting the Earth’s climate by increasing temperatures and contributing to air pollution, which in turn affects public health (Fang G. et al., 2022). Factors such as rapid population growth, widespread industrialization, and growing energy needs have led countries to focus as shown in Figure 1 on renewable energy sources and energy-saving measures (Dong F. et al., 2022). It’s essential to recognize that economic expansion, a key component of GDP, fuels energy demand, especially in industrial activities, thereby increasing carbon emissions (Wang et al., 2022). Moreover, globalization, which makes it easier to enter new markets, has led to higher production levels, further boosting energy use and emissions (Fang T. et al., 2022). A lack of environmental consciousness among both companies and individuals exacerbates the issue, with economic motives often overriding the environmental benefits of switching to cleaner energy sources (Zhong et al., 2022; Pan et al., 2022). Tackling carbon emissions effectively calls for a strategic and cost-efficient approach. This necessitates a renewed investigation to enhance resource efficiency and create a detailed framework for decision-making that identifies key factors and their interconnections. The present study aims to reform the management of carbon emissions in the petrochemical sector by employing an innovative hybrid decision-making model. This model overcomes the gap left by previous research, offering a comprehensive strategy that accounts for uncertain data, focuses on cost-effectiveness, and includes expert insights. It promotes sustainable policies, validated through practical applications and expert assessments, and underscores the importance of regulatory measures, highlighting the role of carbon capture technologies in achieving global sustainability.

2 Literature
The global challenge of rising carbon emissions has spurred worldwide efforts for resolution, marked by intensified research and heightened concerns (Lin and Guan, 2023; Pang et al., 2023; Yu et al., 2023). Studies emphasize a direct link between economic growth, driven by business investments, and increased carbon emissions (Cui et al., 2022). While such investments create employment opportunities, unregulated surges may worsen emissions due to extensive energy consumption in production processes (Li et al., 2022; Lin and Sai, 2022; Liu et al., 2022; Jin et al., 2022; Navidi et al., 2022). Fossil fuel reliance in economic growth amplifies emissions (Akadiri and Adebayo, 2021), observed notably in India and top GDP countries (Zuo et al., 2022). Globalization fuels emissions through increased international trade, enabling multinational investments and necessitating heightened production capacities to meet diverse consumer demands (Xu et al., 2022; Lyu et al., 2022; Dong W. et al., 2022; Ren et al., 2022; Tao, 2022). The global reliance on fossil fuels intensifies emissions, particularly in G20 countries and Argentina (Yuping et al., 2021; Sheraz et al., 2021; Xiaoman et al., 2021; Qamruzzaman, 2022). Studies highlight globalization’s reduced environmental sensitivity, leading to heightened production, energy demands, and waste generation (Akram et al., 2022; You and Zhang, 2022; Yunzhao, 2022; Abushamah and Skoda, 2022). Advocating for heightened environmental awareness, studies stress its pivotal role in addressing carbon emission challenges (Zhang et al., 2021; Razmjoo et al., 2021). Financial considerations contribute to emissions, as businesses prioritize cost-effective fossil fuels over renewables (Kuang et al., 2022; He et al., 2022). Mitigating this requires enhancing the cost competitiveness of renewable energy through research, development, and governmental incentives (de Oliveira and Moutinho, 2022; Gu et al., 2022; Sun and Zhang, 2022; Aihua et al., 2022; Guo et al., 2021). Efficient strategies, employing fuzzy decision-making models, can minimize carbon emissions (Guo et al., 2021). Refinery-chemical integration, particularly focusing on reducing oil usage while increasing the production of value-added chemicals, has emerged as a pivotal direction for the sustainable advancement of the petrochemical sector (Wong et al., 2023; Statista, 2023). While this integration offers the advantage of efficient crude oil utilization, it presents challenges in balancing increased petrochemical output with decreased environmental impact. Following the US, China is recognized as the second-largest nation in terms of oil refining capacity and chemical consumption. By 2030, the number of refineries in China is projected to rise from 220 in 2018 to 245, with processing capacity escalating from 611.68 million tons to 956.30 million tons (Simayi et al., 2021; Independent Commodity Intelligence Service, 2023). This underscores the tension between sustainable development goals and industry expansion. Furthermore, in 2021, petrochemical production contributed to approximately 25.5% of the total industrial VOC emissions and 20.0% of the total industrial carbon emissions (United Nations Environment Programme, 2023). The situation concerning wastewater and solid waste generation remains concerning. Additionally, China has enacted a series of regulations aiming for the petrochemical industry to reduce its energy intensity and CO2 emissions by 10.0% and 12.5%, respectively, from the 2020 levels (National Development and Reform Commission of the People’s Republic of China, 2022). Consequently, there is a pressing need for collaborative reduction and optimization, given the homologous nature of multiple pollutants and carbon emissions. Petrochemical processes exhibit an inseparable elemental relationship across various units due to energy-intensive production and feedstocks that act as energy carriers. This complexity complicates the quantification of material or energy loss, as well as waste emissions, because of their intrinsic role in material-energy coupling (Deng et al., 2023; Alazaiza et al., 2022). Therefore, a precise integrated analysis is crucial for managing complex systems and guiding pollution abatement. To elucidate the coupling relationship within an integrated system, several studies have been conducted on petrochemical production, especially in refineries (Sun et al., 2020; Sarwer et al., 2022; Thanigaivel et al., 2022). Ye et al. (2022) developed a simulation model that established an inherent relationship between delayed coking and hydrotreating in a refinery, quantifying the impact of upstream reaction condition changes on downstream products. Mohseni et al. (2019) employed an interpretive structural modeling technique to identify interrelations between different refining production modes, including setup reduction and pull production. These models, within a multi-factor management framework, enable the tracking of reaction pathways and synergistic material-energy transformations. Nevertheless, with the trend towards refinery-chemical integration, it is insufficient to explore the refinery alone, as petrochemical manufacturing also significantly influences material-energy interactions and system stability (Zhang et al., 2023).
2.1 Motivation/research gap
Previous investigations (Ignatius et al., 2016), (Yu et al., 2014), (Dinçer et al., 2023), and (Ubando et al., 2013) have encountered obstacles in identifying and implementing precise methods for curbing carbon emissions, prompting the need for this study to predict feasible reduction strategies and assess their efficacy accurately. The cited works lack sufficient granularity for thorough data analysis, hampering comprehensive understanding and effective decision-making. Moreover, their models struggle with managing non-membership values and falter when parameters are subdivided into sub-parameters. To overcome these limitations, we introduce an advanced framework integrating intuitionistic fuzzy set theory with hypersoft set theory, resulting in the Intuitionistic Fuzzy Hypersoft Set (IFHSS) approach. This methodology offers two key advancements: first, it expands the spectrum of membership (truth) and non-membership (falsity) values, and second, it enhances the management of parameters with nested sub-parameters, enabling more nuanced and accurate analysis. Our research focuses on devising effective emission reduction strategies within the petrochemical sector by targeting energy consumption, optimizing CO2 mitigation, and minimizing operational costs. The objective is to pinpoint the most economically viable solutions for achieving these goals. The findings aim to provide actionable insights for policymakers and industry stakeholders, empowering them to make informed decisions on carbon reduction initiatives.
3 Methodology
Addressing carbon emissions, highlighted by globalization and economic expansion (Fang G. et al., 2022; Ren et al., 2022; Tao, 2022), necessitates considering environmental awareness and financial factors (Qamruzzaman, 2022; Yunzhao, 2022). However, simultaneous resolution proves impractical due to associated costs, prompting a fresh investigation utilizing three programming-based decision-making techniques (Al-Kasasbeh et al., 2022). These methodologies offer a comprehensive exploration of emission management, introducing each with code demonstrations adaptable to real-world scenarios. The study focuses on prioritizing contributors to carbon emissions in the petrochemical sector, starting with the Entropy-based approach. This method utilizes entropy to identify significant emission contributors and recommends cost-effective mitigation strategies across three phases (Al-Kasasbeh et al., 2022). The study aims to guide further research in integrating decision-making with artificial intelligence and machine learning in emission reduction within the petrochemical industry. In this study, three methodologies are employed. First, a coding-based IHSS entropy approach is used to identify the primary sources of carbon emissions. Second, similarity measure techniques are applied to determine the most cost-effective and beneficial carbon emission reduction strategies. Lastly, a parametric TOPSIS method is utilized to rank various carbon emission reduction techniques.

3.1 Example
In the petrochemical industry, rising carbon emissions pose challenges amid increasing global demand driven by population growth and technological advancements. Current methods fall short in addressing the need for sustainable solutions. Identifying primary emission factors and proposing effective reduction techniques is crucial, despite complex implementation risks. Six carbon emission factors are studied: Feedstock Processing , Energy Consumption , Combustion of Fossil Fuels , Chemical Reactions , Waste Management , and Transportation . These factors are examined alongside unique attributes , such as Economic Development, Industrial Structure, and Operational Risk. A combination space results from . Expert opinions are sought to determine influential emission factors. Management plans to integrate evidence using IHSS implementations outlined in Tables (Fang G. et al., 2022; Dong F. et al., 2022; Wang et al., 2022; Fang T. et al., 2022; Zhong et al., 2022; Pan et al., 2022). IHSS will be transformed into fuzzy hypersoft sets, denoted by (Atanassov, 1986). Entropy values for different sources (e.g., Feedstock Processing, Energy Consumption) are calculated using Python programming. For instance, the entropy of Feedstock Processing is 13.10. The optimal solution with the least entropy ((Feedstock Processing)) suggests it as the primary contributor to carbon emissions in the petrochemical industry. Although only a limited number of Tables 1, 2 have been depicted here, the remaining ones will be managed with the aid of programming.

3.2.1 Example
In the realm of petrochemical industries: The pursuit of techniques to curtail carbon emissions has become paramount. Innovative technologies like Carbon Capture and Storage (CCS), Renewable Feedstocks, and Energy Efficiency measures are revolutionizing the sector. CCS involves capturing carbon dioxide emissions from industrial processes and storing them underground to prevent their release into the atmosphere. Process Intensification aims to optimize chemical processes to minimize energy consumption and waste generation. Renewable Feedstocks focus on using sustainable raw materials instead of fossil fuels to produce chemicals. Energy Efficiency measures concentrate on reducing energy consumption during petrochemical production processes. Embracing these advancements holds immense potential to significantly mitigate carbon footprints in the petrochemical industry, fostering sustainability and environmental responsibility. To simplify, we provide data solely for two Carbon Capture Storage and ideal carbon emission reduction technique. Detailed materials related to these methods are available in the supplementary files for further review. Python programming can facilitate this process; please see 1 and the supplementary material for the Python code for the specific code involved.

3.3 Using a TOPSIS-Based optimised IHSS classifier for evaluations of carbon emissions in the petrochemical industry
The petrochemical industry faces a critical challenge in reducing carbon emissions to combat climate change. To address this, a multifaceted approach is crucial, exploring various strategies from energy-efficient practices to technological advancements. The introduction of a Multi-Criteria Decision Making (MCDM) system centered on the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) offers a holistic strategy to evaluate and rank carbon emission reduction methods. This evaluation considers social, institutional, technological, financial, and environmental factors. Eight types of resources for reduction techniques, such as carbon capture, energy efficiency, and bio-based alternatives, are explored. To practically apply these methods, a Python-based prototype utilizing the TOPSIS algorithm (Please see supplementary material for the Python code), allow for efficient data analysis, prioritization of strategies, and informed decision-making. This coding prototype showcases Python’s effectiveness in addressing complex environmental challenges within industrial domains. To simplify, we’ll showcase solely Tables 3, 4, while utilizing programming to manage the others.

3.4.2 Comparative studies
This segment assesses the effectiveness and benefits of our ENT-driven approach, which integrates SM and TOPSIS within the IFHSS framework, through multiple comparisons. These comparisons underscore both the strengths and limitations of our strategy compared to conventional techniques. We benchmarked our method against several widely-used approaches in the field. A notable limitation of existing techniques is their inability to efficiently categorize attributes into discrete values and handle non-membership elements (falsity). Our proposed methodologies adeptly overcome these challenges, distinguishing themselves from the shortcomings typical of traditional methods. For detailed insights, refer to Table 5.

4 Discussion and concluding remarks
This study aims to thoroughly investigate the key factors driving carbon emissions, develop effective strategies for reducing these emissions, and strike a balance between maintaining competitiveness and controlling costs. To achieve these objectives, the research utilizes three expert-driven decision-making approaches. First, an entropy-based IFHSS (Intelligent Fuzzy Hybrid System) calculation is employed to pinpoint the primary sources of carbon emissions, revealing that Feedstock Processing stands out as a crucial contributor within the petrochemical sector. This insight underscores the importance of focusing on specific processes that significantly impact overall emissions. Second, a similarity measure method is applied to assess various carbon emission reduction techniques, identifying carbon capture and storage (CCS) as one of the most promising strategies for mitigating emissions. This technique is highlighted for its potential effectiveness in the sector. Third, the study utilizes a TOPSIS-based IFHSS approach to prioritize strategies such as Carbon Offsetting and Renewable Energy initiatives for emission reductions in the petrochemical industry. This method evaluates multiple parameters and scenarios, ensuring a comprehensive assessment of the most viable options for achieving lower emissions. The findings from this research carry important implications for procurement strategies, management practices, and policy development within both corporate and governmental contexts. The study emphasizes the urgent need for a shift toward sustainable practices, particularly in light of how globalization influences emissions and the management of increasing trade volumes. To facilitate the petrochemical industry’s efforts in understanding and addressing emission factors, a tailored prototype has been developed. This tool assists in evaluating emissions and testing various mitigation strategies. Among the recommended actions are the implementation of stringent regulations, including the adoption of carbon capture technologies, while carefully considering associated costs. The study also suggests that governmental incentives should be established to encourage compliance with these regulations. Furthermore, the research advocates for the development of dynamic technological policies that can adapt to emerging advancements and regulatory changes in the field. Looking ahead, future studies could expand their focus beyond the petrochemical sector to encompass other significant carbon-emitting industries such as steel, cement, and power generation. These sectors face similar challenges regarding emissions and energy consumption. By applying lessons learned from the petrochemical industry, it is possible to devise innovative strategies and enhance carbon management practices across these other domains. This interdisciplinary approach could serve as a blueprint for promoting a broader transition towards sustainable operations throughout various industrial sectors.
