This article presents the different intermodal transport systems in selected countries in the world, with an indication of their development and impact on environmental protection. The conducted research indicates much faster development of intermodal transport as compared to the transport of goods in other technologies. The studies were based on the latest obtainable statistics on intermodal transport from Asia, Europe, North America, and Australia. In all the cases examined, it is apparent that intermodal transport is supported by state authorities and international intermodal transport associations. The scientific and cognitive value of the article is expressed in the collection of a large number of materials, their systematization and generalization of conclusions. The literature on this subject lacks such comprehensive scientific studies, and this study will therefore clearly fill the research gap.
