Maritime compliance: UK Monitoring, Reporting & Verification (UK MRV) – The third CO2 reporting scheme


( As a reminder to Owners / Managers, after Brexit on 1 January 2021, the UK MRV became the third CO2 reporting scheme relevant for shipping companies, alongside the EU MRV and IMO DCS regulations. It is applicable to vessels >5000 GT calling at UK ports.

First reporting period for UK MRV emissions reports is 2022

The monitoring of UK-related voyages will be required from 1 January 2022. By 2023, operators and managers responsible for vessels subject to the UK MRV scheme shall submit their first annual emissions report for 2022.

No separate monitoring plan for the UK MRV

It is important to note that the EU MRV monitoring plan (MP) will remain valid for the UK MRV, i.e. no separate UK MRV monitoring plan is required. By carrying the EU MRV MP, the vessel will comply with both the UK MRV and EU MRV regulations, and, as such, have the highest flexibility to operate in the UK as well as in the EU.

Monitoring and reporting for UK MRV

Shipping companies will have to submit their first UK MRV emissions reports to verification bodies in early 2023.

Combining the verification of the UK MRV, EU MRV and IMO DCS compliance through a single, standardized process offers efficiency and ease and is strongly recommended.

Scope of UK MRV

It applies to ships above 5,000 gross tonnage in respect of CO2 emissions released during their voyages from their last port of call to a port of call in the United Kingdom and from a port of call in the United Kingdom to their next port of call, as well as within ports of call in the United Kingdom.

The content of the Monitoring Plan, the Emission Report and the Document of Compliance remains the same as in the EU MRV except for the following changes:

  • “EU MRV Procedures” to be substituted by “MRV Procedures” and “EU MRV Regulation” by “MRV Regulation” in the Monitoring Plan template.
  • Electronic template of Emission Report and Document of Compliance to be published soon by the Secretary of State and available on the website.
  • The Emission Report will be submitted to the Secretary of State.

Important Note: Emissions Reports under UK MRV will have to be verified exclusively by UKAS-accredited verifiers.

Consequences on EU MRV Emission Reports

Since the UK is not a member of the European Union anymore, the following changes are expected for the 2021 MRV Emission Report and list of EU MRV voyages:

  • Voyages from UK to EU ports should now be reported in category “from non-EU to EU” (e.g. a voyage from Felixstowe, UK to Valencia, Spain).
  • Voyages from EU to UK ports should now be reported in category “from EU to non-EU” (e.g. a voyage from Le Havre, France to Dover, UK).

Until further rule is agreed between the UK and the EU, voyages between UK and EU ports (either directions) have to be reported under both UK MRV and EU MRV.

Clarifications about the UK MRV regime

To avoid duplication, voyages between UK and EEA ports will NOT have to be reported under the UK MRV, and viceversa. Data on these voyages should continue to be submitted to the European Commission under the EU MRV regime.

Emissions data for voyages between UK ports, between UK and non-EEA ports, and vice-versa, and from vessels at berth in a UK port will need to be included in the UK MRV emissions report.

An assessed UK MRV monitoring plan needs to be in place by the end of 2021. If a ship already uses a monitoring plan under the EU MRV regime, the ship operator should confirm with the verifier if this is suitable for the UK MRV regime, or if changes are needed.
