This paper aims at providing a comprehensive review of the latest technologies developed within the context of EU funded projects, for the purpose of contributing to zero emission and carbon-neutral port operations. To identify the latest developments in a) technologies that enhance educated decision making; b) platforms ensuring seamless communication; c) technologies dealing with physical processes automation and d) technologies addressing energy management & GHG emissions reduction, the present review and evaluation incorporates a critical up-to-date analysis of the current leading-edge products and services in port operations. These advancements are identified in recent and upcoming EU funded projects and are described in trade journals and port-related industry sources of information. The impact of the developed technologies and solutions on the greening of operations and broadly on the port sector are demonstrated in an effort to highlight the rising technological tendencies. The present review also attempts to align these findings with the implementation of the key “green” technologies in ports, offering a state-of-practice approach.
