The sustainable smart supply chain is enabled by advancements in business and information technology that are both environmentally conscious and intelligent. This forward-thinking movement prioritizes additional measures to ensure compliance with social and environmental standards. The Internet of Things (IoT) is a key element of this technology architecture. In this study, we propose a sustainable supply chain framework based on the IoT, consisting of four distinct phases. To demonstrate the intrinsic relationship between data collection processes and industries impacted by environmental sustainability, we constructed a framework by evaluating relevant materials and consulting with experts. This plan has garnered the support of local governments due to its comprehensive approach to making environmentally sustainable decisions throughout the supply chain. As a result of its emphasis on technical solutions, this framework has the potential to make it easier for businesses to develop eco-friendly supply chains.
