<p>This study examines the impact of technological advancements on the sustainable performance of supply chains in the fast-moving consumer goods (FMCG) industry, with a particular focus on the mediating roles of Green Innovation and Green Supply Chain Practices. Data were collected from 313 supply chain executives in Bangladesh using a structured questionnaire. A purposive sampling technique was employed to ensure responses from professionals directly involved in supply chain operations and technology adoption. The data were analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) in SmartPLS4 to assess the relationships between technological advancements, mediators, and sustainable performance. SPSS was used for descriptive analysis, including the demographic profiling of respondents. The findings indicate that Artificial Intelligence (AI) and Autonomous Robots significantly enhance sustainable supply chain performance, whereas the effect of Supply Chain Information Systems (SCIS) is less pronounced, highlighting the need for further investment in SCIS integration in Bangladesh. The study further confirms that Green Innovation and Green Supply Chain Practices act as mediators, strengthening the relationship between technology adoption and sustainability. This research underscores the importance of aligning technological advancements with sustainability-driven strategies to optimize supply chain performance. It recommends investing in AI and robotics, promoting eco-friendly innovations, acquiring ISO 14001 certification, and enhancing SCIS implementation. Ultimately, this study advocates for a holistic approach that integrates technology and sustainability to address contemporary business challenges and contributes to broader environmental objectives.</p>
