Strategies for sustainable transport, and consequently sustainable mobility, require the use of cleaner vehicles without harmful emissions. The use of alternative fuels contributes to realization of set strategies and different types of alternative fuels are increasingly present in the transport sector. There is great potential in the use of alternative fuels in public transport systems, since this mode of transport plays a very important role in sustainable mobility. The aim is to replace the conventional bus fleets with vehicles with newer and cleaner technologies. Within this paper, alternative types of fuels used in public bus transport will be presented, as well as practical examples of the application of these modes of transport.
