The manufacturing industry faces challenges in surviving due to factors such as limited natural resources, evolving client demand, and worldwide competitiveness. Manufacturing companies must use creative solutions to get beyond these obstacles. Researchers and practitioners are becoming interested in enhancing the performance of small and medium-sized industries in India through the integration of Lean manufacturing and Net zero manufacturing. Finding the enablers for lean manufacturing and net zero manufacturing synergy is essential for any manufacturing organisation. Finding and analysing lean manufacturing enablers within the framework of net zero manufacturing is the goal of this study. Previous research has not examined the factors that facilitate Lean manufacturing in the context of net zero manufacturing in Indian manufacturing companies, which is what drives the present topic of research. The research methodology involves a comprehensive literature review to identify the enablers, followed by categorisation of these by using the fuzzy-DEMATEL (Decision-Making Trial and Evaluation Laboratory) method based on their causation and influencing effects. Authors from the current study observed that ‘Data-driven decision making’, ‘Circular economy practices, and ‘optimisation of processes are the top three ‘Cause’ group of enablers of lean in synergy with Net zero manufacturing. In further analysis, authors observed that the establishment of collaboration between suppliers, lower operating costs, and Enhancement of Employee Engagement and Training are the top three ‘Effect’ group of enablers. These enablers are affected by the enablers who come under the ‘cause’ group. Based on the observation of the current study, manufacturing organisations should plan their strategies. Managers with policies that are supportive can give the firm the leadership and direction it needs to promote Lean in the context of Net zero manufacturing techniques.
