Sulphur and nitrogen oxide emissions
Emissions of sulphur oxides are mainly a consequence of the sulphur content of the fuel used. As a consequence of the new sulphur directive that came into effect on 1 January 2015, the limit value for maximum sulphur content in fuel used in the Baltic Sea, North Sea, English Channel, Canada and the United States has been lowered from the previous 1 percent to 0.1 percent.
Concordia Maritime also endeavours to minimise emissions of nitrogen oxides. All of the fleet vessels were built after 1 January 2000, which means they meet the IMO Tier 1 standards and therefore have 13 percent lower nitrogen oxide emissions per tonne of fuel compared with ships that do not meet the standards. Two fleet vessels also meet the Tier 2 standards, and therefore have a further 15 percent lower nitrogen oxide emissions per tonne of fuel.
