MRV compliance

Reporting 

The monitoring and reporting system needs to be sufficiently detailed to capture all the data required by the regulation. Monitoring and reporting shall be complete and cover CO2 emissions from the combustion of all fuels while ships are at sea and at berth, and they shall be separately reported. Appropriate measures shall be applied to avoid any data gaps within the reporting period, which is defined as one calendar year, and it shall be ensured that any sources of inaccuracies are reduced.

Methods for reporting fuel consumption

The actual fuel consumption for each voyage shall be determined and calculated using one of the following methods: 

  • Bunker fuel delivery note (BDN) and periodic stocktakes of fuel tanks
  • Bunker fuel tank monitoring on board
  • Flow meters for applicable combustion processes
  • Direct CO2 emission measurements
Any combination of these methods, once assessed by the verifier, may be used if it enhances the overall accuracy of the measurement.

Reporting on a per-voyage basis 

From 1 January 2018, companies shall monitor emissions for each ship, falling under the scope of the MRV regulation, on a per-voyage basis and aggregate the voyage data in an annual report. The monitoring on a per-voyage basis shall cover the following parameters: 

  • Port of departure and port of arrival, including the date and hour of departure and arrival
  • Amount and emissions factor for each type of fuel consumed in total
  • CO2 emitted
  • Distance travelled
  • Time spent at sea
  • Cargo carried
  • Transport work, which is defined as: distance travelled x cargo carried
The regulation allows for exemption from the per-voyage monitoring when all the ship’s voyages during the reporting period either start from or end at a port under the jurisdiction of a member state, or the ship performs more than 300 voyages during the reporting period.

Monitoring on an annual basis

In addition to per-voyage reporting, the MRV regulation further requires monitoring on an annual basis. As a consequence, the following parameters shall also be monitored:

  • Amount and emissions factor for each type of fuel consumed in total
  • Total aggregated CO2 emitted within the scope of this regulation
  • Aggregated CO2 emissions from all voyages between ports under a member state’s jurisdiction
  • Aggregated CO2 emissions from all voyages which departed from ports under a member state’s jurisdiction
  • Aggregated CO2 emissions from all voyages to ports under a member state’s jurisdiction
  • CO2 emissions which occurred within ports under a member state’s jurisdiction at berth
  • Total distance travelled
  • Total time spent at sea
  • Total transport work
  • Average energy efficiency
