1. Introduction

In recent decades, the global business landscape has witnessed a profound shift towards sustainability, driven by mounting environmental concerns, regulatory pressures, and heightened consumer expectations (Vachon & Klassen, 2008; Sarkis, 2012). This evolution has transformed the way organizations perceive and manage their supply chains, where traditional paradigms of efficiency and cost minimization are increasingly being complemented by considerations of environmental impact, social responsibility, and long-term viability (Seuring & Müller, 2008; Pagell & Shevchenko, 2014). Central to this transformation is the role of inventory management within supply chains. Inventory, comprising raw materials, work-in-progress goods, and finished products awaiting distribution, represents a critical component in the flow of goods across global networks (Simchi-Levi et al., 2008). Traditionally viewed as a buffer against demand variability and supply disruptions, effective inventory management now assumes a dual mandate: not only to optimize operational efficiencies but also to minimize environmental footprint and enhance social welfare (Mason-Jones et al., 2000; Diabat & Kannan, 2017). The imperative for sustainable inventory management stems from the interconnected challenges posed by climate change, resource scarcity, and ethical consumerism. These factors have catalyzed a paradigm shift in corporate strategies, compelling businesses to adopt practices that mitigate environmental degradation and uphold ethical labor standards throughout their supply chains (Carter & Rogers, 2008; Pagell & Wu, 2009). Such shifts are underscored by the recognition that unsustainable practices not only jeopardize ecological resilience but also engender reputational risks and legal liabilities, thereby impacting long-term profitability and stakeholder trust (Handfield et al., 2019; Chatterjee et al., 2020). Moreover, the evolution towards sustainable inventory management is intricately linked to broader sustainability frameworks and initiatives. For instance, the United Nations Sustainable Development Goals (SDGs) provide a comprehensive blueprint for global sustainability efforts, emphasizing the integration of economic prosperity, social equity, and environmental stewardship (United Nations, 2015). Within this context, inventory management serves as a critical lever for achieving several SDGs, including responsible consumption and production (Goal 12) and climate action (Goal 13), by optimizing resource utilization and reducing carbon footprints across supply chains (Golinska et al., 2019; Nguyen et al., 2021). In practical terms, achieving sustainability through inventory management involves a multifaceted approach that encompasses technological innovation, strategic partnerships, and stakeholder collaboration (Sarkis et al., 2011; Christopher & Peck, 2004). Technologies such as advanced analytics, artificial intelligence, and Internet of Things (IoT) facilitate real-time visibility and predictive insights into inventory flows, enabling companies to optimize storage capacities, minimize wastage, and respond proactively to demand fluctuations (Ivanov & Dolgui, 2021; Zhang & Zhou, 2021). Furthermore, strategic partnerships with suppliers and distributors are pivotal in fostering transparency and accountability throughout the supply chain, ensuring compliance with environmental regulations and ethical sourcing practices (Chopra & Meindl, 2016; Seuring & Gold, 2013). Beyond operational efficiencies, sustainable inventory management also entails a cultural and organizational shift within companies. It necessitates the cultivation of a sustainability-oriented mindset among employees, from procurement officers to warehouse managers, fostering a collective commitment to environmental stewardship and ethical conduct (Dubey et al., 2019; Pagell & Halldorsson, 2002). This cultural transformation is underpinned by robust governance structures and performance metrics that align corporate objectives with sustainability goals, thereby embedding sustainability into the corporate DNA and ensuring long-term resilience (Zhu & Sarkis, 2007; Handfield et al., 2021). The evolving discourse on sustainable inventory management underscores its pivotal role in navigating the complex interplay between economic prosperity, environmental preservation, and social responsibility within contemporary supply chains. By embracing innovative technologies, forging strategic alliances, and fostering a culture of sustainability, businesses can not only mitigate risks and enhance operational efficiencies but also contribute meaningfully towards global sustainability imperatives. As organizations continue to embrace this transformative journey, the integration of sustainable inventory management practices will emerge as a cornerstone of resilient, responsible, and future-ready supply chains.

2. Literature Review

The literature on sustainable inventory management within supply chains reflects a growing body of research that underscores its critical importance amidst evolving global challenges. Sustainable inventory management involves strategies and practices aimed at minimizing environmental impact, optimizing resource utilization, and enhancing social welfare throughout the supply chain. This section reviews key scholarly contributions that illuminate various facets of this complex and multidimensional field. A foundational aspect of sustainable inventory management revolves around the concept of environmental sustainability. Scholars emphasize the need for businesses to reduce their ecological footprint by adopting practices that mitigate greenhouse gas emissions, conserve natural resources, and promote circular economy principles (Pagell & Wu, 2009; Ivanov & Sokolov, 2018). This entails not only optimizing inventory levels to minimize waste but also embracing technologies such as advanced forecasting models and green logistics strategies to enhance efficiency and reduce carbon emissions (Ivanov & Dolgui, 2021). Moreover, the integration of social sustainability considerations within inventory management practices has garnered significant attention. This includes ensuring ethical sourcing practices, promoting fair labor standards, and fostering inclusive supply chain relationships (Seuring & Gold, 2013; Pagell & Shevchenko, 2014). Such initiatives are crucial for addressing stakeholder expectations, enhancing brand reputation, and mitigating risks associated with labor violations and social unrest (Handfield et al., 2019). Technological advancements play a pivotal role in advancing sustainable inventory management capabilities. For instance, the application of artificial intelligence (AI) and Internet of Things (IoT) technologies enables real-time tracking of inventory flows, predictive analytics for demand forecasting, and optimization of transportation routes to minimize environmental impact (Ivanov & Dolgui, 2021; Zhang & Zhou, 2021). These technologies not only enhance operational efficiencies but also support decision-making processes that prioritize sustainability metrics alongside traditional economic considerations. In recent years, there has been a growing recognition of the strategic implications of sustainable inventory management for corporate competitiveness and resilience. Organizations that effectively integrate sustainability into their supply chain operations are better positioned to mitigate risks associated with regulatory changes, resource scarcity, and consumer preferences for eco-friendly products (Sarkis et al., 2011; Dubey et al., 2019). This strategic alignment not only fosters long-term sustainability but also enhances organizational agility and innovation capacity in response to evolving market dynamics. Furthermore, the literature underscores the role of governance structures and stakeholder engagement in driving sustainable inventory management practices. Effective governance frameworks promote accountability, transparency, and compliance with environmental regulations across the supply chain (Handfield et al., 2021). Meanwhile, proactive engagement with suppliers, distributors, and other stakeholders facilitates collaborative efforts to address shared sustainability goals, such as reducing waste, improving resource efficiency, and promoting social responsibility (Seuring & Müller, 2008; Chopra & Meindl, 2016). Marketing initiatives also play a crucial role in promoting sustainable inventory management practices within organizations. By effectively communicating their sustainability efforts to consumers, companies can enhance brand reputation, attract environmentally conscious customers, and differentiate themselves in competitive markets (Khan et al., 2024). This consumer-centric approach not only drives demand for sustainable products but also incentivizes suppliers to adopt greener practices throughout the supply chain (Emon & Chowdhury, 2024). Emotional intelligence among supply chain professionals has emerged as another critical factor influencing sustainable inventory management. Leaders with high emotional intelligence can foster a culture of sustainability within organizations, empower teams to embrace change, and navigate complex stakeholder dynamics effectively (Emon & Chowdhury, 2024). This interpersonal skill set is essential for driving collaboration, innovation, and continuous improvement in sustainable supply chain practices (Emon, 2023). Economic considerations also underpin the rationale for sustainable inventory management. While initial investments in green technologies and sustainable practices may incur higher costs, long-term benefits such as cost savings through reduced waste, improved operational efficiencies, and enhanced brand value outweigh these initial expenditures (Emon, 2023). Moreover, businesses that proactively address environmental and social risks are better positioned to attract investment, secure financing, and maintain investor confidence in an increasingly sustainability-conscious market (Khan et al., 2020). Barriers to growth in sustainable inventory management include challenges such as limited technological infrastructure, regulatory complexity, and organizational inertia (Khan et al., 2020). Overcoming these barriers requires collaborative efforts across sectors, investment in research and development, and policy support to incentivize sustainable practices and innovation (Emon et al., 2024). The literature on sustainable inventory management within supply chains underscores its multifaceted nature and strategic importance in addressing contemporary global challenges. By integrating environmental, social, and economic considerations into inventory management practices, organizations can enhance resilience, drive innovation, and create long-term value for stakeholders. Future research should continue to explore emerging technologies, governance mechanisms, and collaborative strategies that promote sustainable supply chain practices and contribute to global sustainability goals.
