This year, HSL (Helsinki Region Transport) will pay 1.7 million euros in environmental bonuses to bus operators who cut their particulate and carbon emissions. HSL awards bonuses for using biodiesel, bioethanol and biogas as well as for exhaust gas after-treatment. HSL awarded the bonuses through a bidding process held in 2018.
The measures taken by bus operators reduce carbon emission from buses by 18.6 tons, nitrogen oxides by 20.2 tons and fine particles by 530 kilos a year.
HSL’s goal is to cut nitrogen oxide, fine particle and carbon emissions affecting air quality by more than 90 percent from 2010 levels by 2025.
