Abstract

The manuscript examines some of the main factors influencing the level of environmental friendliness of urban bus transport, with an emphasis on the modernization of rolling stock and the use of alternative fuel sources as innovative transport solutions. A 10-year period, from 2010 to 2020, is considered, for which an analysis is made of how much harmful emissions are reduced in buses with a higher Euro standard on the example of an enterprise for providing public transport in the capital of Bulgaria – “Stolichen Avtotransport” EAD. Transport research and innovation are crucial to ensuring fast, safe and clean transport for citizens and businesses in big cities. The transport sector needs innovative solutions more than ever, as the cost of transporting passengers will increase in value and time, especially after rising global fuel prices. Reducing the level of harmful emissions from urban transport will lead to environmental sustainability, which is a goal and priority of all EU countries. That is why the search for innovative approaches in the field of transport is crucial.
