This study investigates and prioritizes the barriers to implementing green ports by gathering expert evaluations from eight specialists on eight critical obstacles. The research uses the Fuzzy Analytic Hierarchy Process (Fuzzy-AHP) to turn people's ambiguous assessments into consistent priority weights. This solves the problem of how people see things differently. The combined pairwise comparison matrix, fuzzy geometric means, and normalized weights show that the biggest problem is a lack of regulatory incentives (B2), followed by limited help from the port authority (B8) and the high cost of retrofitting (B1). Financial risks, such not knowing how much money you'll make on an investment (B7), are also quite essential. On the other hand, obstacles relating to technology, stakeholder opposition, worker skills, and awareness are not as critical. The defuzzified data and graphs show that systemic and governance-related problems are more important than social and operational problems. The results give policymakers and port management evidence-based priorities that will help them establish focused plans and phased initiatives. The report gives useful tips for getting over institutional and financial problems by focusing on the most important ones first. This speeds up the move toward green ports that are both sustainable and competitive.
