To combat the global warming, the International Maritime Organization, IMO, set an ambitious level for future CO2 emissions in April 2018. The goal is to reduce CO2 emissions from shipping by at least 50 per cent by 2050 compared to 2008.  

During the last few years, Finnlines has made many investments in ships’ energy efficiency. During 2018, six ro-ro vessels were lengthened and the 30 per cent capacity increase will cut the energy consumption per transported unit compared to the original vessel. Other efforts to reduce energy consumption include change of propeller blades, running on optimal speed, load, trim and timetable planning. Anti-fouling is normally not used as Finnlines’ ships operate in ice conditions, but on three ro-pax ships, which solely operate in ice-free conditions in the Southern Baltic, the silicone anti-fouling has been applied. Consequently, Finnlines ships’ total fuel consumption has decreased by nearly 30 per cent since 2008. In 2018, Finnlines’ vessel traffic consumed 335,287 tons of heavy fuel oil and diesel oil. This represents a decrease of 1 per cent when allocated on each transported cargo ton compared to 2017.
