Digitalization and Industry 4.0 are transforming supply chain operations worldwide. However, traditional supply chain finance (SCF) practices often overlook sustainability. This study explores how SCF, supported by Industry 4.0 technologies, can enhance supply chain sustainability by integrating the Environmental, Social, and Governance (ESG) principles. By examining five real-world cases using a qualitative case study approach, we develop a conceptual framework that captures the roles and interrelationships among key actors in sustainable supply chain finance (SSCF). This study employed cognitive mapping to visually synthesize these complex processes. The findings reveal that innovative technologies, stakeholder engagement, and targeted financial incentives can drive sustainable improvements across supply chains. The insights from this research offer valuable guidance for practitioners and policymakers and provide a foundation for future empirical studies.
