This research focuses on the role emerging technologies have in driving changes in procurement and supply chain management processes toward better sustainability and redoubtable compliance. Traditional procurement and supply chain management strategies undergo dramatic change continually becoming complex with the deep sustainability and regulatory compliance at the core of the sourcing landscape. This research delves into how such innovations as Artificial Intelligence (AI), Blockchain, the Internet of Things (IoT), and Digital Product Passports (DPPs) essentially revolutionize practice within procurement and supply chain logistics from 1PL to 6PL, along with their implications for sustainability and compliance. The research generally used a mixed-method approach, integrating a review of literature, analysis of case studies, and analysis of technology. This will provide a conceptual model of how these technologies will be incorporated into the supply chain operations presented in such a manner that it will bring quick, efficient, and responsive visibility of the activities that take place in the ecosystem of the supply chain in a manner that is compatible with global sustainability and regulatory standards. The research points out some of the challenges that are inherent in the technologies' development such as integration difficulties, lack of scalability, and strategic framework to be used in the implementation. This research will elaborate on the role of technology in driving sustainable procurement and supply chain management to give practical guidance to organizations seeking to achieve unsurpassed operational excellence while ensuring environmental responsibility and regulatory compliance.
