Possible future ECA

New Emission regulations

The Shipping Industry is facing increasingly fierce requirements regarding air emissions. IMO Tier III regulations became valid January 1, 2021, focusing on nitrogen oxides (NOx) limits. The environmental requirements provide a NOx reduction of around 75 percent from previous requirements. This is a drastic reduction that small and large shipping companies must comply with when operating in Emission Controlled Areas (ECA), which consists of the Baltic Sea, North Sea, English Channel and the coasts of United States.

IMO Tier II & IMO Tier III – your choice
