Carbon & Costs

UK Fuel, UK ETS and MRV

Treat sulphur, carbon and data obligations as three separate checks on a UK voyage.

Assess UK fuel/port rules, UK ETS and MRV applicability as separate obligations.

Your action sequence at a glance

  1. UK fuel rule

  2. Voyage/port scope

  3. UK ETS data plan

  4. Report/surrender dates

MASTER • RESPONSIBLE OFFICER • COMPANY

Start with these 6 checks

  1. Identify UK ports, domestic voyages and in-port events.
  2. Verify at-berth sulphur and local fuel requirements.
  3. Check UK ETS GT/type/exemption scope with company.
  4. Match monitoring plan and responsible operator/Registry process.
  5. Separate emissions year, reporting and surrender dates.
  6. Reconcile overlapping EU MRV/ETS and FuelEU data tasks.

Educational checklist. Completion is not operational/compliance approval; use the relevant vessel permits/forms separately.

Open rules and technical detail

1 · Fuel at berth

MCA guidance explains the 0.10% m/m sulphur requirement at UK ports, with changeover/exemption details. A UK port outside an ECA is not automatically exempt. Verify port definition, anchoring status and local instructions separately.

Reference: UK MCA — MGN 400 amendment 1, fuel at berth ↗

2 · UK ETS starts 1 July 2026

Current UK guidance brings covered domestic voyages and UK in-port activity emissions for ships ≥5,000 GT into scope from 1 July 2026; offshore inclusion starts in 2027. Do not classify a UK–foreign voyage automatically as domestic; assess port emissions and current scope separately.

3 · Reporting and surrender calendar

The first maritime scheme year is 1 July–31 December 2026. UK guidance provides transitional surrender by 30 April 2028 for 2026 and 2027; annual verified reporting remains separate. UK allowances/Registry are not EU EUAs/Union Registry.

4 · Do not treat old UK MRV as the current regime

2026 legislation revokes the former standalone UK MRV arrangements. That does not remove UK ETS monitoring/reporting or EU MRV eligibility on EU voyages. This chapter does not invent a FuelEU-equivalent scheme called “UK FuelEU”.

Scenarios and self-check

Onboard scenarios

UK–EU voyage: only UK requirements?

No. Assess EU MRV/ETS/FuelEU and UK port/fuel/ETS events separately.

Old UK MRV revoked: stop all carbon records?

No. Current UK ETS and applicable EU duties remain.

LEARNING CHECK

Think of your answer, then reveal the explanation

Is a UK allowance an EUA?

No; different schemes and surrender processes.

Outside-ECA UK port: no at-berth fuel check?

No. MCA and port conditions may still apply.

Self-assessment only; no exam result, personnel record or competence certificate is generated.
