The practice of managing the supply chain to lessen negative environmental effects and promote sustainability is known as "green supply chain management" (GSCM). This includes reducing energy and water usage, reducing unused, and utilizing renewable or recyclable materials. Green supply chain management also requires that companies look into the environmental impacts of their suppliers and customers, making sure their practices are sustainable as well. Companies that take part in green supply chain management are oftentimes rewarded with financial incentives, improved customer relations, and employee satisfaction. The Indian leather industry which is the most polluted industry needs GSCM practices at war footing not only for their sustainable operations but for humankind also. Human behavior is a complex and ever-evolving field of study. It is a combination of psychological, biological, and social factors that influence how people think, feel, and act. Human behavior is affected by a variety of external and internal stimuli, including environmental conditions, cultural norms, and individual experiences. As such, it is important to understand the various factors that can shape our behavior to better understand ourselves and others. As a result, it's crucial to comprehend and rate the behavioural aspects that have an impact on GSCM adoption in the Indian leather business. The Green supply chain management decision-makers would find this to be useful in establishing the chain of action for the effective employment of green practises in the Indian leather industry. ISM is a useful approach for understanding the complex relationships between various behavioral elements and their hierarchies in the context of green supply chain management (GSCM) adoption. It can be used to identify the key behavioral factors that influence the effective adoption of GSCM in the Indian leather industry, as well as the interdependencies between these factors. This can help GSCM decision-makers in the Indian leather industry to better understand the challenges and opportunities for implementing sustainable practices throughout their supply chain and to develop effective strategies for addressing them. Additionally, ISM can be used to identify the key drivers and barriers to GSCM adoption, which can inform the development of targeted interventions to promote sustainable practices in the Indian leather sector.
