New 2026 ECAs: Canadian Arctic and Norwegian Sea
Two new emission control areas have already been in force since 1 March 2026: the window to adjust passage planning and bunkering is narrower than it looks, because the SOx/PM limits kick in as early as 2027.
Operational Explanation
Resolution MEPC.392(82), adopted at MEPC 82 (October 2024), designates two new Emission Control Areas (ECA) under MARPOL Annex VI: Canadian Arctic waters and the Norwegian Sea north of 62°N. The amendments entered into force on 1 March 2026, making these two areas operational ahead of the future North-East Atlantic ECA (1 September 2027, adopted separately at MEPC 84).
As with other ECAs, the limits apply in stages: the SOx/particulate matter limits (fuel sulphur content below 0.10% m/m, unless an equivalent EGCS is used) take effect from 1 March 2027, one year after the amendments entered into force.
The two NOx regimes are different from each other
A single criterion does not exist: the two areas have different regimes. MEPC.392(82) amends two distinct sub-paragraphs of Regulation 13.
Canadian Arctic: one criterion, and retroactive relative to entry into force. The resolution adds a new sub-paragraph at the end of Regulation 13.5.1.3 — the residual sub-paragraph covering ECAs other than the Baltic and the North Sea — reading: “that ship is constructed on or after 1 January 2025 and is operating in the Canadian Arctic Emission Control Area”. One date only. There is no contract date and no delivery date: all that counts is that the ship be “constructed” on or after 1 January 2025 — that is, under the general Annex VI definition, that the keel be laid, or the construction be at a similar stage, from that date. The date precedes entry into force of the designation by fourteen months: a ship laid down in early 2025 is already subject to Tier III the moment it enters the area, with no adaptation period whatsoever.
Norwegian Sea: the three dates, and here they are. Here the resolution does not touch the residual sub-paragraph but inserts a new sub-paragraph 13.5.1.2.3, alongside the Baltic and the North Sea, with the customary triple definition: building contract placed on or after 1 March 2026; in the absence of a contract, keel laid or similar stage of construction on or after 1 September 2026; delivery on or after 1 March 2030. The text reads: “For the Norwegian Sea Emission Control Area, ‘ship constructed on or after 1 March 2026’ means a ship: .1 for which the building contract is placed on or after 1 March 2026; or .2 in the absence of a building contract, the keel of which is laid or which is at a similar stage of construction on or after 1 September 2026; or .3 the delivery of which is on or after 1 March 2030”.
Why the difference matters on board. The same ship may be subject to Tier III in one of the two areas and not in the other. A ship whose keel was laid in March 2025 and which was delivered in 2027 is Tier III in the Canadian Arctic (keel after 1 January 2025) and is not in the Norwegian Sea (none of the three criteria met). Treating the two ECAs as a single deadline leads to answering badly the simplest question a PSCO can ask.
Where the boundaries run
The perimeter is the first operational fact about an ECA.
The two areas are not described in the same way, and that is the surprising part. Res. MEPC.392(82) adds two new sub-paragraphs to Regulation 13.6: “.5 the Canadian Arctic Emission Control area, which means the area described by the coordinates provided in appendix VII to this Annex; and .6 the Norwegian Sea as defined in regulation 13.9.4 of Annex II of the present Convention.” One is given by coordinates, the other by reference to another Annex.
Canadian Arctic: Appendix VII, new paragraph 5. The same resolution introduces it thus: “The Canadian Arctic area comprises two segments: .1 starting at the Yukon mainland at 68°54'.00 N, 137°0'.00 W; following the coordinates listed below and ending at the north coast of Hans Island at 80°49'.91 N, 66°27'.40 W, connected by geodesic lines connecting the following coordinates in World Geodetic System 1984 (WGS84) datum”. There follow 179 points, numbered 1 to 179, in the WGS 1984 datum. The perimeter is to be loaded into ECDIS from that table, not reconstructed by hand.
Norwegian Sea: no coordinates of its own. It is the only one of the new ECAs not described in Appendix VII, and the resolution says so expressly by rewriting its paragraph 1: “The boundaries of emission control areas designated under regulations 13.6 and 14.3, other than the Baltic Sea, the North Sea, and the Norwegian Sea areas, are set forth in this appendix.” The boundary sits in Regulation 13.9.4 of Annex II — the Annex on noxious liquid substances, not the one on air. It is a cross-reference between two Annexes, and that is why at first sight it looks like a transcription error: it is not.
Declared limit: the text of Regulation 13.9.4 of Annex II has not been opened. The phrase “north of the 62nd parallel” used elsewhere on this page describes the area in the customary way, but its source is not declared and it does not necessarily coincide with the Annex II definition. For passage planning, that definition governs, not this phrase.
Both designations take effect on 1 March 2026.
Regulatory Reference
MARPOL Annex VI, amendments adopted under Resolution MEPC.392(82) (MEPC 82, October 2024): designation of Canadian Arctic waters and the Norwegian Sea (north of 62°N) as new Emission Control Areas. Adoption: 4 October 2024. Entry into force of the amendments: 1 March 2026. NOx Tier III — Canadian Arctic: new sub-paragraph at the end of Regulation 13.5.1.3, ships “constructed” on or after 1 January 2025, single criterion. Norwegian Sea: new sub-paragraph 13.5.1.2.3, contract on or after 1 March 2026, absent a contract keel on or after 1 September 2026, delivery on or after 1 March 2030. SOx/PM: the resolution adds the two areas to the list in Regulation 14.3 without fixing any date; 1 March 2027 follows from the twelve-month exemption that Regulation 14 of Annex VI grants to ships operating in a newly designated area. Declared limit: the date 1 March 2027 is not written in MEPC.392(82); it is the product of that exemption applied to entry into force, and it is the concurring reading of the classification societies' circulars.
Scope of Application
Every ship navigating in Canadian Arctic waters or the Norwegian Sea, with obligations that intensify progressively between 2026 (entry into force) and 2027 (SOx/PM limits fully applicable). The two perimeters have different sources: the Canadian Arctic is described by coordinates in appendix VII to Annex VI, while the Norwegian Sea is the one “as defined in regulation 13.9.4 of Annex II”. The customary phrase “north of 62°N” is not the legal definition and must not be used as a boundary.
Procedure / How to Complete It
- Update charts, ECDIS and passage planning systems with the official boundaries of both new ECAs — the appendix VII coordinates for the Canadian Arctic, the Regulation 13.9.4 definition of Annex II for the Norwegian Sea — and not with the “north of 62°” description. Keep them distinct from the future North-East Atlantic ECA.
- Verify the applicable date for your ship: the SOx/PM limits apply from 1 March 2027, twelve months after designation. For NOx, check the two areas separately: in the Canadian Arctic it is enough to establish that the keel was laid on or after 1 January 2025; in the Norwegian Sea you need the building contract date (1 March 2026), failing that the keel-laying date (1 September 2026), and the delivery date (1 March 2030).
- Review fuel changeover planning for entry into and exit from both new areas, including any Arctic-specific operational considerations.
- Verify the availability of compliant fuel (or the operability of an equivalent EGCS) at ports of call and bunkering ports along habitual Arctic and Norwegian routes.
- Update crew training and the voyage planning checklist to include the two new areas as distinct, not as a generic extension of the existing ECAs.
Practical Example
Example: a Company with regular routes through the Norwegian Sea reviews, starting already in 2026, its bunkering contracts at habitual Norwegian ports to secure the availability of fuel compliant with the 0.10% sulphur limit ahead of the 1 March 2027 deadline.
What Typically Goes Wrong
Common Mistakes Mistake Library
| Mistake | Consequence | How to avoid it |
|---|---|---|
| The two new ECAs (Canadian Arctic and Norwegian Sea) confused with the future North-East Atlantic ECA, treating them as a single 2027 deadline | Non-compliant navigation in Arctic/Norwegian waters as early as 2026-2027, wrongly believing the deadline is single and further away | Keep the three areas distinct (Canadian Arctic and Norwegian Sea: designation 2026, limits 2027; North-East Atlantic: entry into force 2027, limits 2028) in planning, with their respective dates and reference resolutions |
| Availability of compliant fuel at Arctic ports not verified with sufficient advance notice | Risk of non-compliance or operational delays due to lack of fuel on board | Verify the availability of compliant fuel (or EGCS operability) well in advance, accounting for the seasonality of Arctic navigation |
What the PSCO Checks
Operational Tips
- Don't treat the two new ECAs (Canadian Arctic, Norwegian Sea) as a simple preview of the future North-East Atlantic ECA: they are distinct designations, with different resolutions and deadlines.
- If you operate in Arctic waters, plan compliant fuel bunkering with a wider margin than for ECAs in busier waters, due to seasonality and lower supplier availability.
- Check NOx twice, once per area: the criteria differ. In the Canadian Arctic there is a single threshold, keel laid on or after 1 January 2025 — a date earlier than entry into force, hence with no adaptation margin at all. In the Norwegian Sea the three dates of sub-paragraph 13.5.1.2.3 apply.
Preparation checklist
Educational checklist. This summary supports learning and preparation only. It does not replace the vessel’s approved procedures, manuals, statutory documents, company SMS, or applicable official requirements. Completing it demonstrates neither compliance nor readiness for an inspection: it shows that a list has been read, not that the ship is in order. Always verify the current documents carried on board.
- Charts and passage planning updated with the boundaries of both new ECAs
- Applicable date for SOx/PM limits verified (1 March 2027 in both areas)
- NOx regime verified separately for each area: Canadian Arctic, keel from 1 January 2025; Norwegian Sea, contract 1 March 2026 / keel 1 September 2026 / delivery 1 March 2030
- Fuel changeover planning reviewed for entry into/exit from both areas
- Availability of compliant fuel (or equivalent EGCS) verified at habitual Arctic/Norwegian ports
- Crew trained on the distinction between the two new ECAs and the future North-East Atlantic ECA
