On April 7-11th 2025, the Marine Environment Protection Committee 83rd session (MEPC 83) introduced the IMO Net-Zero Framework, which aims to achieve net-zero GHG emissions from international shipping by around 2050.
Additionally, the North-East Atlantic was approved as an Emission Control Area (ECA) for SOx, PM and NOx. This ECA covers the Exclusive Economic Zones (EEZ) and territorial seas of Greenland, Iceland, the Faroe Islands, Ireland, the United Kingdom, France, Spain and Portugal.
The Canadian Arctic and Norwegian Sea will also become ECAs on March 1, 2026. Ships operating in these areas will be required to meet the IMO Tier III NOx emission standards.
MEPC 83 also agreed to:
Provide a means for certification of engines using non-carbon-containing fuel or mixtures of carbon-containing and non-carbon-containing fuels
Develop of guidelines for the management of ammonia effluent generated by ships using ammonia as fuel
Strong momentum in reducing NOx emissions in this sector is critical, with international maritime comprising over 10% of global NOx emissions.
At OzAmmonia, we are ready to take advantage of this momentum to enable the maritime industry to achieve ever-tightening NOx regulations at low costs. Our patented electrolyser system can convert NOx emissions to renewable ammonia, a valuable fuel for the maritime industry.
