In short

Reading time: 1 min
  • What it sets out:
    • The executive order sets out rules on NOx emissions from marine diesel engines and on NOx emission control areas.
    • Engines must meet limit values that depend on, among other things, the year the ship was built and whether the ship sails in a NOx emission control area.
  • Who: The rules apply to marine diesel engines with an output of more than 130 kW on Danish ships and ships in Danish sea territory. The rules also apply to foreign ships in the exclusive economic zones, to the extent that this is compatible with international law. Engines that are intended only for use in emergencies (e.g. in lifeboats or emergency equipment) are exempt, and there are several other exemptions, e.g. for certain older ships and for ships that only sail in their own flag state's waters.
  • When: The executive order was scheduled to enter into force on 20 May 2025. This has not yet been confirmed.
