Exploring Challenges and Enablers of Sustainable Supply Chains in Indian Automotive SMEs for Enhancing Long-Term Competitiveness

This study explores the contribution of Indian automotive Small and Medium Enterprises (SMEs) in progressing Sustainable Supply Chain Management (SSCM) through the Triple Bottom Line (TBL) framework by focusing on economic, environmental, and social sustainability dimensions. Case studies from top Original Equipment Manufacturers (OEMs) such as Tata Motors, Maruti Suzuki, Mahindra & Mahindra, Ashok Leyland, Eicher Motors, and Hero MotoCorp show how SMEs are involved with green procurement, lean manufacturing, and reverse logistics while challenging barriers of cost, technology, and limited infrastructure. The study highlights both progress and challenges: Maruti Suzuki’s supplier policy necessitates ISO 14001 compliance, Mahindra has capitalized on renewable energy, Ashok Leyland has enhanced efficiency through lean production, and Hero MotoCorp reduced emissions by 43% through logistics amendments. Until now many SMEs fight with high initial capital investment and weak digital willingness. The government initiatives, such as FAME and PLI schemes, motivate sustainable practices and electric movement, but uneven implementation still limits SME benefits. The findings propose SMEs’ long-term competitiveness depends on innovation, partnerships, and policy support. Creating cooperative ecosystems, prompting Industry 4.0, and enlightening access to financing are essential for qualifying SMEs to change toward sustainable, resilient, and globally competitive supply chains.
