In the coming years, bus fleet emissions in the Helsinki Metropolitan Area will be significantly reduced as buses start to run on new generation biofuel. The aim of the three-year trial project of HKL, YTV, Proventia and Neste Oil is that in 2010 approximately half of the buses operated in the Helsinki Metropolitan Area will use NExBTL, a biodiesel developed by Neste Oil and produced from renewable raw materials. NExBTL produces significantly less particulate and nitrogen oxide emissions than traditional diesel. In addition to the biofuel, new kind of continuously operating exhaust gas purifiers are tested in some of the buses. With this biofuel trial, HKL and YTV aim at leading the way in environmentally friendly public transport in Finland. During 2008, the intention is to expand the trial and up-grade it into an EU project. Read more...
