PTAs have the possibility to act as trendsetters for sustainable mobility. Helsinki Region Transport (HSL) already has managed to cut both local and greenhouse gas emissions of buses significantly. The goals are quite ambitious;by 2025 HSL wants to achieve a reduction of 90 % or more for emissions of carbon dioxide and pollutants, compared to the year 2010. Within the partnership with HSL, VTT has tested more than 200 buses, and conducted several field tests. The technologies and fuels covered include diesel, renewable diesel, ethanol, methane (natural gas, biogas), hybrids and battery electric vehicles, creating a comprehensive database. This paper discusses theprogress in the performance of buses with conventional powertrains. Furthermore, it presents the actions taken by HSL to introduce advanced biofuels as well as electric buses in Metropolitan Helsinki. Finally, it presents HSL’sfleet strategy going towards 2030.
