Reducing emissions of pollutants from transport is clearly one of the main challenges of the constantly developing world. Because the environmental impact of different means of transport is significant, it is necessary to cut down on fossil fuels and turn to more eco-friendly solutions, e.g., electric vehicles. Almost all European countries are now adapting their transport policies to this new paradigm. Nonetheless, due to large economic disparities, these processes are currently at different levels of implementation in Western and Eastern Europe. The main focus is on private electric cars and more traditional means of transport, rather than water trams. This article presents possible means of developing water tram lines in Gdańsk served by hybrid or full-electric vehicles. The analysis presented herein reflects the multidimensional nature of the issue. The article provides data on the socio-economic situation in the city, technical issues related to the implementation of such tram lines, and the possible consequences of introducing a new means of transportation into the existing system. A key part of the analysis is the identification of anticipated economic and environmental consequences of introducing both hybrid and full-electric vehicles into the system. A comprehensive socio-economic and technical-environmental analysis of the possibilities of developing urban electromobility in the form of urban passenger shipping in post-communist countries, such as that presented in this paper, has not been previously published.
