This study examines the role of Artificial Intelligence (AI), Internet of Things (IoT), and Blockchain in enhancing sustainability within Green Supply Chain Management (GSCM). The main objective is to analyse how these technologies improve efficiency, reduce environmental impact, and support better decision-making in supply chain operations.

The research is based on both primary and secondary data. Primary data was collected through a structured questionnaire from 120 respondents, while secondary data was gathered from research papers, journals, and online sources.

The findings indicate that all three technologies have a positive impact on sustainability. Among them, AI is perceived as the most effective due to its ability to improve forecasting and optimise operations. IoT helps in real-time monitoring and resource management, while Blockchain enhances transparency and trust within the supply chain.

Statistical analysis, including descriptive statistics and t-test, confirms that the impact of these technologies is significantly higher than neutral expectations. However, challenges such as high implementation costs, technical complexity, and resistance to change still exist.

The study concludes that the integration of AI, IoT, and Blockchain can significantly improve sustainable supply chain performance, making businesses more efficient and environmentally responsible.
