Scope of EU MRV
The EU MRV regulation applies to all voyages to, from, and between EU and EEA ports, regardless of the flag state of the vessel. Monitoring must cover CO2 emissions from the combustion of all fuels on board — including those used by auxiliary engines, boilers, and inert gas generators — as well as key aggregated data points such as distance travelled, time at sea, and cargo carried.
The Monitoring Plan
Ecosail's EU MRV module begins with the Monitoring Plan — the vessel-specific document that describes how fuel consumption data will be collected and verified. The platform includes a Monitoring Plan template builder that guides users through all required elements, including the monitoring method (BDN-based, bunker tank monitoring, or flow meters), fuel type definitions, and the procedures for handling data gaps. Completed Monitoring Plans are stored securely and can be submitted to accredited verifiers directly through the platform.
Voyage-Level CO2 Capture
Voyage-level CO2 data is captured automatically from noon reports, bunker delivery notes, and fuel consumption records. The module applies the correct THETIS-MRV CO2 emission factors for each fuel type and aggregates voyage data into the annual emissions report. Where voyages straddle EU and non-EU portions, the module correctly apportions emissions to the EU-reportable segment, ensuring no under- or over-reporting.
Annual Emissions Report and THETIS-MRV
The annual Emissions Report generated by Ecosail's EU MRV module is formatted precisely for upload to THETIS-MRV, the European Maritime Safety Agency's (EMSA) online reporting system. The report includes all mandatory fields: total CO2 emissions (in tonnes), CO2 emitted in port, CO2 emitted at sea, total fuel consumed by fuel type, transport work, and efficiency parameters. Automated validation checks flag any data anomalies before submission, reducing the risk of verification queries.
Verifier Integration
Verifier integration is a key feature of Ecosail's EU MRV module. Accredited MRV verifiers — class societies and independent verification bodies — can be granted secure access to review voyage data, flag data quality issues, and issue the Document of Compliance. The entire verification workflow is managed within the platform, with a complete audit trail of verifier comments, company responses, and final sign-off.
Integrated Compliance with IMO DCS and CII
For companies managing EU MRV alongside IMO DCS and CII, Ecosail's integrated approach is a major efficiency advantage. A single underlying data set — collected once, validated once — feeds all three regulatory frameworks. This eliminates the data reconciliation headaches that arise when separate systems produce conflicting fuel consumption figures, and ensures that EU MRV, IMO DCS, and CII reports are internally consistent.
Link to EU ETS
The EU MRV regulation has been significantly amended to support the EU ETS integration. From 2024, MRV data is the basis for calculating EU Allowance (EUA) obligations under the EU ETS. Accurate MRV data is therefore not just a compliance requirement but a direct financial obligation. Ecosail's module ensures that MRV data quality is sufficient to support both reporting requirements without additional data collection effort.
Fleet Management Reporting
Fleet management reporting in Ecosail's EU MRV module provides real-time visibility across all vessels subject to EU MRV. Fleet managers can instantly see which vessels have complete data, which have data gaps, and which are awaiting verification. Automated reminders and workflow triggers ensure that annual deadlines — the 31 March submission deadline and the Document of Compliance issuance timeline — are met across the entire fleet.
Ready for Tomorrow's Requirements
As EU maritime climate policy continues to evolve — with proposals for expanded MRV coverage, new greenhouse gas inclusions, and enhanced port state enforcement — Ecosail's EU MRV module is updated to reflect regulatory changes as soon as they are adopted. Partner with Ecosail for EU MRV compliance that is accurate today and ready for tomorrow's requirements.
