Abstract: The rapid growth of world trade and the progress of digitization have led to the need for more complex infrastructures to support the increased amount of cargo and the adaptation of logistical support to the new data. At the same time, tackling climate change is one of the most important challenges the global community is facing today, and ports, which are major sources of pollution, must contribute to the protection of the environment. In this regard, smart ports, through the use of technological innovations in order to enhance port activities and services, aim to increase the competitiveness and economic viability of an area, while, at the same time, contribute to the reduction of greenhouse gas emissions and energy consumption. The purpose of the present paper is to present the principles on which the construction and operation of a smart and green port should be based, as well as ways to make the port industry more environmentally friendly.
