The object of the comparative study is to gain methodological experience in comparing alternative transport systems in terms of environmental performance. The study has been confined to the operational phase of the transport means both with regard to impacts from mobile subsystems to transportation system and impacts from stationary subsystems to transportation system. This study will focus on emissions, toxic releases, noise and land use. The work has been confined to the operational stage of the transport means. Hence depletion of natural resources, production and scrapping are not included. The subject case study refers to two different intermodal transport systems.
