European Case Studies

Organizations and local governments in various European countries and cities have launched and successfully implemented bus fleet renewal programs to modernize public transport. This chapter includes further selected results from external case studies and lessons learnt from projects in European countries such as Austria, Germany, Romania, Spain andthe United Kingdom.

Collection of Case Studies from Clean Fleets

The Clean Fleets Project conducted several bus fleet renewals in many European cities. The overview of case studies e.g. includes the introduction of the world’s first diesel-electric hybrid double deck buses with induction charging infrastructure in London (2014), a study about a Biomethane bus fleet in Reading (2014), ordered EEV buses in Romania (2014), a case study about electric microbuses in the city centre of Vienna (2014) or the implementation about a hybrid bus project in London (2015).
Please note that the overview of the Clean Fleets case studies does not only include bus fleet renewals but also other fleet renewal case studies not specifically covering buses.

Case Study on EEV certified biomethane bus service in Reading, UK

This case study further focuses on the CNG powered buses with biomethane bus fleet in Reading that can be found above. The buses were launched in the public transportation system in 2013 and resulted in an increase of 20% more passengers per year using these biomethane buses. As a result, the city of Reading purchased further CNG buses and in an increased frequency of the “greenwave” buses.

Case Study on the purchase of 165 electric and CNG fuelled buses in Madrid, Spain

In order to reach its GHG emissions reduction targets, the Municipal Transport Company of Madrid (EMT) started an open tender procedure for 165 buses of different ranges powered by electricity or CNG fuel to be delivered in the following years. As a result, EMT is now one of the public transportation companies with the most CNG fuelled vehicles in Europe. Although the sustainable buses were slightly more expensive than convential diesel buses, the emissions oproduced by EMT buses was significantly reduced. Further eco-driving training for drivers ensured a further reduction of the enviornmental impact.

Case Study on the transformation of a diesel bus fleet to an electric bus fleet in Aachen, Germany

Aachen’s public transport operator ASEAG tested different innovative environmentally friendly drive concepts for its buses on suitability for the public transport. In particular this included measurements of fuel consumption and noises. Due to the negative results of hybrid buses, light buses were purchased. An articulated hybrid bus was also converted to be fully electric.
