    Abstract

    The public transport authority (PTA) in Helsinki Metropolitan Area, Helsinki Region Transport (HSL) and VTT Technical Research Centre of Finland have been assessing and documenting performance (regulated emissions, carbon dioxide emissions and energy consumption) of city buses for some 20 year. The data generated is used by HSL as an element supporting the tendering of bus services, but also to develop future bus fleet strategies. The report at hand is the first report in English on the continuous bus performance evaluation for HSL. lt is based on the Finnish 2018 annual report, but it has been expanded to serve as a stand-alone summary report of the activities. Between the spring of 2002 and end of 2018, WT has tested in total 178 city buses for HSL. The sample includes Euro I - Euro Vl diesel buses, Euro ll - Vl gas (CNG) buses and EEV ethanol buses. This report presents a summary of all data generated It is fair to say that current buses are much cleaner than the ones of the early 90's. The results cleady show the positive development in NO" and PM emission levels over the years, from Euro I to Euro Vl. lt is also evident that the step from Euro V/EEV to Euro Vl brought about the biggest relative reduction so far.
