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.
