The Government of Iceland (Minister for the Environment and Natural Resources) has issued a regulation tightening fuel requirements for ships, which effectively bans the use of heavy fuel oil in the territorial sea of Iceland. The change is brought about by an amendment to Iceland’s regulation on sulphur content of certain liquid fuels (reglugerð nr. 124/2015). The permissible sulphur content of marine fuels used in the territorial sea and internal waters of Iceland is lowered from 3.5% down to 0.1%. In addition, the permissible sulphur content of marine fuels is lowered down to 0.5% within the Icelandic Pollution Prevention Zone outside of the territorial sea. More information here.
