On the contrary. Jokeri Light Rail will reduce emissions significantly. The carbon dioxide emissions are estimated to decrease by 85%, nitrogen oxide emissions (NOx) are estimated to decrease by 95% and particle emissions (PM) are estimated to decrease by 70% compared to the ‘Jokeri Bus’ (line 550). Jokeri Light Rail will also increase the use of public transport and reduce passenger car traffic, which will reduce the carbon dioxide emissions and pollutants caused by car traffic. The light rail line is free of local emissions.
