This paper analysis the importance of green transformation technologies in port infrastructure management. As sites for the exchange of products and commodities, ports are essential to international trade and transportation. Sustainability is, however, severely hampered by the environmental effects of port operations, which include noise pollution, congestion, and contamination of the air and water. The application of Internet of Things (IoT) technology to the green transformation of ports is the subject of this article. Ports may improve environmental sustainability, lower emissions, and streamline operations by utilizing automation, data analytics, and IoT sensors. The basic elements of IoT-enabled green ports are covered in this study, including predictive maintenance, energy management, smart infrastructure, and emissions monitoring. A case study of Durres Port Authority is analyzed by describing the actual IoT and smart technologies that are identified. The possibilities for the integration of digital twin are considered to improve the monitoring and operation issues which are the most important for the strategic role that the most important port in Albania plays. Furthermore, there is important to mention the obstacles to IoT adoption for green port efforts, including cybersecurity threats, interoperability issues, and stakeholder engagement techniques. Overall, the study contributes to the larger objective of building a greener and more sustainable marine sector by offering insights into the transformative potential of IoT technology in promoting sustainability and resilience in port operations.
