Abstract
Ports play an important role in connecting the domestic and global economies. Zero emissions port models are actively developed and frequently utilized to fulfill economic objectives while reducing environmental effect. The cold ironing system is one of technological methods assisting ports in transitioning to zero emissions port models. Although a number of ports have successfully implemented it, many other seaports, particularly those in developing countries, continue to face numerous challenges in implementing cold ironing. The aim of this research is to investigate the factors influencing the adoption of cold ironing. The study used a quantitative method, conducting a survey of 215 port managers from the North, Central, and South of Vietnam. The findings indicate that economic incentives and regulation have a positive impact on the adoption of cold ironing at ports. While lack of initial capital and lack of standardization are barriers to the implementation of cold ironing. The last section will look over the study's results and implications in greater detail.
