EMSA opens up MRV reporting portal

A portal has been created by the European Maritime Safety Agency for ship operators to report annual CO2 emissions of their vessels.

The portal, under EMSA’s THETIS reporting system allows owners to inform European regulators about their emission monitoring plans and to submit verified annual emission data. These are both requirements under the EU CO monitoring Reporting and Verification of ship CO2 emissions that are currently in force and with deadlines about to impact shipping.

THETIS is the information system created by the European Union to help the region’s port state inspection regime.

The rules apply to all ships over 5,000 gt and sailing to, from and between European ports. Owners need to have a verified monitoring plan place by the end of this month. The plans need to be accredited by an approved Accreditation agency, and be  submitted into the THETIS MRV portal.

Owners need to begin recording emissions related to voyages to form and between European ports from January 1 2018, and have these verified and reported by April of 2019. Submission of each vessel will then be annual after that, but also be replicated somewhat by similar IMO rules that come into play in 2019.

The European rules are part of the EU attempts to include maritime transport into its overall policy to reduce greenhouse gas emissions. While the MRV rules  themselves do not mandate any attempts to make reductions, there is the expected likelihood they will in the near future once two or three years of data has been accumulated.

In its statement EMSA said: “The move is expected to encourage the uptake of greenhouse gas emission-reduction measures within the maritime sector, as the emissions data will be made public and updated yearly. EMSA was tasked to develop a robust system for the monitoring and reporting of verified data on CO2 emissions, annual fuel consumption and other energy efficiency parameters by the European Commission’s Directorate General for Climate Action.

EMSA’s CO2 MRV reporting system explained

EMSA says its THETIS-MRV system allows companies to work together with accredited verifiers to prepare monitoring plans in a voluntary module and, importantly, to release emission reports and documents of compliance to the European Commission and relevant flag state authorities using the mandatory module.

“Using the information submitted, the European Commission will publish annual aggregated data per ship covering fuel consumption, CO2 emissions and average energy efficiency indicators, among others,” wrote EMSA.

This has been a cause of concern by some shipowners groups that see this as sensitive information. The IMO data collection system will not be publishing such data when it starts.


The European Union has one rule in force and one in the making.  The regulation on monitoring reporting and verification of CO2 emissions has come into force with some immediate deadlines that certain ship operators need to prepare for.
(The actual regulation is found here)
It applies to all ships of 5,000 gt and over calling at European ports. It demands that these vessels monitor, record, have verified and report voyage specific CO2 emissions and work done (There are other greenhouse gases but the regulation specifies CO2 as the most prevalent one and therefore the only one for this regulation
The regulation expressly references itself being amendable as and when an international rule is agreed:
(34) The Union MRV system should serve as a model for the implementation of a global MRV system. A global MRV system is preferable as it could be regarded as more effective due to its broader scope. In this context, and with a view to facilitating the development of international rules within the IMO for the monitoring, reporting and verification of greenhouse gas emissions from maritime transport, the Commission should share relevant information on the implementation of this Regulation with the IMO and other relevant international bodies on a regular basis and relevant submissions should be made to the IMO. Where an agreement on a global MRV system is reached, the Commission should review the Union MRV system with a view to aligning it to the global MRV system.
