Abstract: As a key node in the transportation network, ports connect the inland hinterland with the outside world, providing strong guarantees for the sustainable development of domestic trade and economy. However, the increasing port activities, while promoting regional economic growth, have also brought increasingly serious environmental problems to the local area. Promoting port emission reduction is a key way and important lever for China’s transportation industry to promote ecological civilization construction. By using CiteSpace to systematically review the literature on port emission reductions in recent years in the China National Knowledge Infrastructure (CNKI) and Web of Science databases, it was found that significant achievements have been made in port emission reduction technology, policy system construction, and emission reduction effect evaluation. However, there are still problems such as insufficient research on regional differences and insufficient in-depth analysis of emission reduction costs and benefits. Analyzing the hotspots and trends of port emission reduction research at home and abroad can provide reference for the theoretical research and practical path of coordinated emission reduction governance in Chinese ports. Future research on port emission reduction should focus on regional differences, cost–benefit analysis, and in-depth exploration of the synergistic effects of port emission reduction and regional economic development, in order to provide more comprehensive theoretical support and practical guidance for the green sustainable development of ports.
