UK ETS Site Visits: DNV Urges Early Action Before First Reporting Deadline

Summary

DNV has urged maritime operators to arrange UK ETS site visits ahead of their first verified emissions reporting deadline on 31 March 2027. Its guidance highlights the need for approved monitoring plans, complete fleet records and supporting evidence, with physical visits normally expected and virtual assessments requiring regulatory approval.

Verification preparations move into focus

UK ETS site visits are becoming an immediate compliance priority for shipowners and managers as the maritime sector approaches its first annual reporting cycle under the expanded emissions trading scheme.

DNV has recommended completing visits by the end of February 2027, leaving time to finalise verification before the March submission deadline. The first reporting period covers emissions generated between 1 July and 31 December 2026.

The classification society’s guidance explains that verification cannot be completed until the required visit has taken place, the operator’s Emissions Monitoring Plan has been approved and the necessary fleet information has been supplied.

Visits focus on how emissions data are managed

The assessment centres on the arrangements used to collect, manage and check emissions information. Verifiers examine evidence, test internal controls and may interview employees responsible for monitoring and reporting.

A visit does not automatically mean boarding every vessel. Where information is managed centrally, the verifier’s risk assessment may support examining the company’s principal data-management location instead.

Operators must nevertheless provide access to whichever locations the verifier considers necessary. This makes coordination between shore-based compliance teams and vessel personnel important, particularly where records pass through several departments before entering the annual report.

Virtual assessments require advance approval

A remote assessment is subject to specific conditions. The verifier must first conclude that a virtual visit can provide reasonable assurance that the emissions report contains no material misstatements.

For operators regulated by the Environment Agency, an application, including the verifier’s risk analysis, must reach the agency by 28 February following the relevant reporting year. Approval may carry conditions, including a requirement for an in-person visit during the next cycle.

Operators should therefore establish the proposed assessment format early. Leaving that decision until the final reporting weeks could reduce the time available to obtain approval or arrange physical attendance.

Monitoring plans and supporting records must align

DNV has identified several documents operators should assemble: the approved monitoring plan, vessel lists, data-flow procedures and relevant supporting evidence.

Its verification process combines ship-level information into a company-level Annual Emissions Report. Supporting records can include bunker delivery notes, applicable cargo samples and proofs of sustainability.

For later reporting periods, DNV recommends coordinating visits with EU maritime emissions monitoring, FuelEU Maritime verification or relevant company audits where practicable. Such coordination could reduce duplicated preparation while allowing each scheme’s requirements to be addressed.

Maritime expansion creates a separate compliance framework

The UK ETS entered maritime transport on 1 July 2026, initially covering cargo and passenger ships of 5,000 gross tonnage and above undertaking covered activities.

Its scope includes domestic voyages between UK ports, journeys returning to the same UK port and relevant emissions during UK port stays. Consequently, vessels serving international routes can have obligations for their UK port emissions even where the international voyage itself falls outside the scheme.

Covered greenhouse gases include carbon dioxide, methane and nitrous oxide. Responsibility normally rests with the registered owner, although it can be transferred to the International Safety Management company through a legally binding agreement.

The company-level framework means operators need a clear allocation of responsibility across their fleets, rather than treating reporting solely as a vessel-by-vessel administrative exercise.

Reporting deadline precedes first allowance surrender

The first reporting deadline must be distinguished from the timetable for surrendering emissions allowances.

Operators must submit their verified 2026 emissions reports by 31 March 2027. However, allowances covering both the 2026 and 2027 scheme years must be surrendered by 30 April 2028 under the initial double-surrender arrangement.

The additional time was introduced to help maritime businesses familiarise themselves with the scheme and establish access to its digital systems. It does not postpone the first reporting obligation.

For operators, the practical priority is to secure verification capacity, resolve documentation gaps and complete the assessment early enough for any corrections. The extended allowance timetable provides preparation time for carbon-market participation, while emissions monitoring and reporting are already under way.

FAQs

When is the first maritime UK ETS reporting deadline?

The verified report covering 1 July–31 December 2026 must be submitted by 31 March 2027.

Does every ship require a physical visit?

Not necessarily. The verifier determines the locations required through a risk assessment, taking account of where emissions data are managed.

Can the visit take place remotely?

Yes, subject to the verifier’s assessment and regulatory approval. The application deadline is 28 February following the reporting year.

When does DNV recommend completing the first visit?

By the end of February 2027, allowing time to finish verification before the reporting deadline.

When must operators first surrender allowances?

Allowances for both the 2026 and 2027 scheme years must be surrendered by 30 April 2028.
