While Norwegian authorities have previously announced that they will introduce zero emissions restrictions in their heritage fjords by 2025, the Norwegian Maritime Authority (NMA) is expected to introduce restrictions starting already next year (2019) and gradually step up the requirements.

In its publication, Navigare, the NMA states that its restrictions will cover air emissions as well as grey-and blackwater and scrubber water in the Geirangerfjord, Nærøyfjord and Aurlandsfjord.

It is currently legal to sail in the Geirangefjord with HFO without exhaust gas cleaning systems as the fjord is north of the North Sea Emission Control Area. The other two fjords are within the ECA.

The NMA will require exhaust gas cleaning systems or low-sulfur fuels such as MGO.

Another proposal, which is said to be circulating for review in Norway, is a speed restriction for all ships above 20,000 tons, which will result in reduced fuel consumption and reduced emissions.

The NMA is also proposing that ships of more than 2,500 tons and carrying more than 100 persons will not be allowed to discharge grey- or Blackwater or scrubber water in the fjords. Visible smoke emissions must meet transparency requirements.

The Navigare article states that the number of ships visiting these fjords in the future is expected to go down and that the oldest ships are expected to leave first.
