Investigations on ships’ and cargo handling equipments’ (CHEs) activities were carried out in this study, including time of ships at at-berth and shift state, working hours of CHEs, and the engine power of ships and CHEs. Meanwhile, the emission inventory was developed based on the power emission estimation methodology and the emission contributions of ships, different types of CHEs, various port areas and operation processes were compared with. The results indicated that ships contributed most to the air pollution among all the pollutant sources and should be given higher priority for the improvement of the air quality. Shore power technology can be applied to the air pollutant mitigation in the future. Yard tractor and the process between port front to yard contributed a lot due to the usage of liquefied natural gas (LNG) on yard tractors. The application of LNG on CHEs should be given further consideration.
