Abstract
The reduction of pollutant emissions in the field of transportation can be achieved by developing and implementing electric propulsion technologies across a wider range of transportation types. This solution is seen as the only one that can offer, in areas of urban agglomeration, a reduction of the emissions caused by the urban transport to zero, as well as an increase in the degree of the health of the citizens. This paper presents an analysis of the direct and indirect environmental aspects of a fleet of real electric buses under service in the city of Cluj-Napoca, Romania. The solution of using 41 electric buses to replace Euro-3 diesel buses (with high pollution levels) in the city’s transport system eliminates a local amount of 668.45 tons of CO2 and 6.41 tons of NOx—pollutant emissions directly associated with harmful effects on human health—annually.

Summary
Contemporary trends of population migration to urban centers and the “metropolization” of urban cities (especially those that are local and regional centers) have been continuously increasing, which has been confirmed by a global increase in population migration With such an increase in the number of inhabitants in these urban agglomerations, problems related to the public transport of passengers (as an integrated part of the functionality and sustainability of a city) have arisen, which must be solved through the prism of several factors, such as efficiency, versatility, punctuality, modularity, and comfort. The fact that, in general, the road transport sector is one of the largest net contributors to the generation of NOx pollutants (about 13% of total pollutant emissions) and 27% of total greenhouse gas (GHG) emissions in the atmosphere at the European level presently cannot be ignored [1] For this reason, the European Union has adopted (and will adopt) numerous laws and regulations related to the substantial reduction of pollutant emissions caused by transport using internal combustion engines as an energy source. Even in the short term, the use of renewable sources (biofuels) has been accepted worldwide as an immediate solution to completely or partially replace fossil fuels (as they can contribute to reducing global GHG emissions); there are many limitations to their use, regarding the protection of the environment
