Research background: Individual car transport significantly burdens the environment, especially in the centres of large cities. There is pollution, traffic jams and an increase in overall noise. In the area of passenger car transport, legislation is being significantly tightened. Therefore, there are also increasing demands on public transport operators in the Czech Republic. Previously, most of the fleet consisted of diesel vehicles. These have been gradually replaced by drives that are significantly more environmentally friendly, such as the Compressed natural gas drive. The requirements defined in relation to the reduction of vehicle emissions are increasingly stricter. A number of cities, not only within the European Union, are addressing significant issues concerning the future of public transport. Purpose of the article: The main objective of the article is to demonstrate an in-depth analysis of the operation of transport vehicles in the Statutory City of Ostrava, both from the cost and environmental point of view. The comparison of transport means using CNG, electric and diesel propulsion is made. Specific factors such as the route profile or the environmental impact of the mode of transport are also taken into account. The extent of the data processed and the multidimensional nature of the assessment offer a unique analysis of the problem. The article provides an exact view of the advantages and disadvantages of operating specific means of transport. Everything is based on data on transport operations in the city of Ostrava (the Czech Republic, EU). Methods: The comprehensive evaluation is based on the application of methods from the field of financial accounting, evaluation of measured data from the operation of transport means and, last but not least, on the analysis of empirical data from the given area. The analysed data set is unique due to the time period, as is the multi-criteria evaluation methodology. Findings & value added: The analysis performed demonstrated the economic viability of operating CNG vehicles. The main added value of the article is the unique multi-criteria evaluation procedure for the vehicles. The paper shows the evaluation of a complex decision problem in the transport field in the form of a case study implemented in the city of Ostrava. The evaluation results then consider both cost and environmental factors, which can be described as a comprehensive and highly innovative approach. The defined assessment can then be applied to other European and world metropolises.

The main objective of the article is to assess the impact of the variable, which is the level of energy efficiency and the financial aspect of the acquisition and operation of zero-emission electric motor boats against the background of their market substitutes in the form of conventionally powered boats in the face of the phenomenon of development and further market expansion of producers of electric motor boats in Poland in conditions for meeting contemporary environmental demands for sustainable development. This goal was achieved taking into account the results of the study carried out taking into account the descriptive and comparative analysis of energy, environmental and economic conditions for the development of a research and development project conducted in 2018–2019 by VT-Sport, concerning the development of a new model of a motorboat along with preparation for implementation into production. The result of the study was an indication of market needs in the scope of further development and expansion of domestic producers of electric drives for motor boats in Poland. The results of the research may constitute a significant contribution to in-depth research and discussions in the field of meeting the conditions and postulates of ecological, economic and social sustainable development in the considered sector of the economy.

Streszczenie: Głównym celem artykułu jest ocena wpływu zmiennej, jaką jest poziom efektywności energetycznej oraz aspektu finansowego nabycia i eksploatacji łodzi motorowych o zeroemisyjnym napędzie elektrycznym na tle ich substytutów rynkowych w postaci łodzi o napędzie konwencjonalnym wobec zjawiska rozwoju i dalszej ekspansji rynkowej producentów łodzi motorowych w Polsce w warunkach spełnienia współczesnych postulatów środowiskowych zrównoważonego rozwoju. Cel ten został osiągnięty z uwzględnieniem efektów badania opartego na analizie deskryptywnej i komparatywnej uwarunkowań energetycznych, środowiskowych i ekonomicznych rozwoju projektu badawczo-rozwojowego prowadzonego w latach 2018–2019 przez firmę VT-Sport dotyczącego opracowania nowego modelu łodzi motorowej wraz z przygotowaniem do wdrożenia do produkcji. Wskazano potrzeby rynkowe w zakresie dalszego rozwoju i ekspansji krajowych producentów łodzi motorowych w Polsce. Efekty badania mogą stanowić istotny przyczynek pogłębionych badań i dyskusji na temat spełniania warunków i postulatów ekologicznych, ekonomicznych oraz społecznych zrównoważonego rozwoju w rozważanym sektorze gospodarki.
