The purpose of this study is to adapt the conditions of Chabahar port and prioritize the important factors that have been proposed by the Eco-Port site for European ports in the last 4 years in order to bring the port toward a green port. This research has moved towards the sustainable development of ports as one of the most important polluting areas in the country. In this study, first, the factors were confirmed with the comments of six environmental experts from the Chabahar port by using the Delphi elite technique in the form of phasing and then ranked the factors by explaining the AHP-adjusted questionnaire. Prioritization of identified factors indicates the predominance of prominent environmental problems in the port under investigation. The study was conducted in two phases, during operation and during development, which in addition to highlighting the current environmental problems, has created plans for the emergence of new phases under construction at the port.
