The aim of this study was to investigate the role of blockchain and digital technologies in enhancing supply chain sustainability. Data was collected through an extensive review of academic literature, industry reports, and case studies. One remarkable finding was that blockchain technology can reduce supply chain fraud by up to 80% by providing an immutable and transparent ledger. The research examined the integration of AI, IoT, and blockchain, highlighting their combined impact on improving operational efficiency, transparency, and reducing environmental footprints. Keeping in mind the fact that supply chains are becoming increasingly complex and environmentally impactful, the paper concluded that the adoption of these technologies is critical for achieving sustainable supply chain practices. The study underscores the need for addressing implementation challenges, such as high costs and data privacy concerns, to fully realise the potential of digitalization and blockchain in creating resilient, efficient, and eco-friendly supply chains. This research provides valuable insights for both academics and practitioners aiming to enhance supply chain sustainability through technological innovation.
