In the context of global carbon neutrality goals and the transition to clean energy, ports have become a focal point due to their significant energy consumption and pollution emissions. This heightened attention has promoted research on green ports, with comprehensive evaluations of their environmental impact serving as a key driver of sustainable transformation. This paper presents a systematic review of 15 years of literature, uncovering key research directions and emerging trends in green port evaluation. It explores the evolution of evaluation methods and indicator systems tailored to diverse evaluation subjects. The findings highlight three key trends: segmentation of evaluation subjects, refinement of evaluation methods, and dynamic adaptation of indicators. By providing a comprehensive overview of the current evaluation practices, this study offers valuable theoretical insights and actionable guidance to support future research and facilitate the practical implementation of green ports initiatives.
