The subject of the paper is the development of the cargo handling equipment in the ports in the context of reducing the exhaust gas emission caused by the operation of cargo handling equipment in ports,that is in the context of reducing their impact to the environment. The development of the ports is closely related to their adaptation to the needs of maritime transport, passenger and tourist traffic, exchange of goods and other, which affects their number, purpose, and equipment. In these times when environmental protection becomes an increasingly important topic of discussion among the professional and scientific audience, and when net-zero greenhouse gas emission strategies are being adopted at the national, regional and global level, the environmental impact of cargo handling equipment in ports, especially harmful emissions, is being reviewed and updated. An increasing number of countries has been implementing environmental regulations in III their legislation, their focus being on eliminating harmful emissions from marine engines. In order to meet the requirements of legal provisions, in addition to manufacturers of cargo handling equipment who are focused on the development of innovative and efficient transhipments with net-zero or low exhaust emissions, the ports also engage with the concept of net-zero emissions in their operations.
