“…Certain studies delve into the necessity of establishing an electric grid for battery charging of electrically powered buses in the context of public transportation [25]. The authors of another paper meticulously scrutinized compressed natural gas (CNG) buses, comparing them with traditional buses fuelled by diesel, which currently dominate the market in many countries [26]. Additionally, diesel blends incorporating bio components are presently in use, as explored in the study, offering a comprehensive evaluation of the impact of various biodiesel blends on the emission profiles of city buses under real-world operational conditions [27].…”

The renewal of the vehicle fleet with environmentally friendly buses that constitute urban public transport within an urban territory, or a proportion of the transport within the territory of cities and municipalities as part of suburban public passenger transport, can make a significant contribution to reducing greenhouse gas and environmental pollutant emissions from transport. As part of the research, we dealt with the research question as to whether the application of the Act on the Promotion of Clean Vehicles (EU (European Union) Directive 2019/1161) will significantly increase the share of environmentally friendly buses by 2032 in the Slovak Republic (SR). The paradox of the application of the new legislation in the Slovak Republic is that, in public transport, the renewal of the vehicle fleet has significantly reduced, and will further reduce, the negative impacts of vehicle operation, but nothing will change significantly in suburban bus transport while a substantial part of the lines start and end at bus stations in city centres and a number of lines are for short distances, which can be operated by electric buses. Thus, the percentage of environmentally friendly automobiles in the Slovak Republic in urban bus transport will increase significantly. In suburban bus transport, we propose to change the legislation of the Slovak Republic in order to partially start increasing the share of environmentally friendly vehicles. Another follow-up research question was whether gross domestic product (GDP) per capita influences the increased share of environmentally friendly buses in the European countries studied. Based on the correlation measure, there is a significant connection between GDP per capita and the proportion of eco-friendly buses in certain nations. In areas with higher GDP, or in more advanced regions, there is a larger percentage of environmentally sustainable buses. The largest share of environmentally friendly buses is in the Nordic countries of Europe, at 13.44%.

“…Other types of vehicles that form an alternative to diesel buses are CNG and LNG vehicles. The benefits and limitations of using CNG buses are shown in the studies completed by, inter alia, Milojevic et al [95], Ivković et al [96], Merkisz et al [97], Yue et al [98], and Tica et al [99]. The study done by Dyr et al [100] shows interesting results of the analysis of costs and benefits of using CNG buses in public transport, whereas Jurkovič et al [101] analysed the possibility of decreasing the chosen environmental indicators by introducing LNG buses into bus transport.…”

This paper focuses on effects of implementing zero-emission buses in public transport fleets in urban areas in the context of electromobility assumptions. It fills the literature gap in the area of research on the impact of the energy mix of a given country on the issues raised in this article. The main purpose of this paper is to identify and analyse economic effects of implementing zero-emission buses in public transport in cities. The research area was the city of Szczecin, Poland. The research study was completed using the following research methods: literature review, document analysis (legal acts and internal documents), case study, ratio analysis, and comparative analysis of selected variants (investment variant and base variant). The conducted research study has shown that economic benefits resulting from implementing zero-emission buses in an urban transport fleet are limited by the current energy mix structure of the given country. An unfavourable energy mix may lead to increased emissions of SO2 and CO2 resulting from operation of this kind of vehicle. Therefore, achieving full effects in the field of electromobility in the given country depends on taking concurrent actions in order to diversify the power generation sources, and in particular on increasing the share of Renewable Energy Sources (RES).

“…Contributions that examine the need for an electrical system for recharging the batteries of electric buses are specific if they were to be deployed in urban public transport [13]. The authors of the paper [14] paid special attention to compressed natural gas (CNG) buses and their comparison with conventional diesel-powered buses, which have a dominant share in countries such as Serbia. Currently, diesel with a certain proportion of bio-component is also used, and the study [15] provides a comprehensive overview of the measurement of the effects of different bio-diesel mixtures on the characteristics of exhaust emissions of city buses in real operating conditions, while the preparation of the fuel mixture of a conventional internal combustion engine is very important from the point of view of emission production [16].…”

The use of alternative fuels and the use of vehicles meeting the strictest emission standards can contribute to improving the impact of road transport on the environment. Therefore, it is also very important to restore buses, which can affect the environment in cities to a certain extent. Achieving an increase in the number and share of ecological buses is possible through several tools. The contribution is focused on the analysis of the EU directive on the support of ecological and energy-saving road transport vehicles and the study of the number and share of ecological buses in European countries, and the data for the Slovak Republic and the Czech Republic, which can also be compared for the same period, are processed in more detail. Due to the growth rate of the number of ecological buses during the period under review, it can be seen that in the Slovak Republic it is definitely necessary to increase the number and the proportion of buses that have a more favourable impact on the environment and are considered ecological.
