In order to assess the forecast capabilities of “ecologizing” the transport and logistics system of Ukraine, we conducted a predictive modeling of the possibilities of using various modes of transport. The primary goal of the modeling was to determine the potential for increasing freight turnover for water and rail transport while reducing the freight turnover for road transport. The research conducted has enabled the formulation of a predictive model for the development of Ukraine's transportation system, taking into account the military events and for the country's post-war recovery. It was confirmed that with the intensification of European integration processes, it is important to address environmental issues related to aligning the national freight transport sector with the standards of the European Green Deal. Therefore, the necessity of utilizing water transport was substantiated, and the potential volumes of maritime and river transport were determined. It was taken into account that with the onset of the war, there are limitations on the use of maritime transport in Ukraine (due to the occupation of territories and ports). Therefore, there is a need to compensate for these losses until the restoration of maritime transport capabilities by activating the use of river transport.
