What it is
EU MRV (Monitoring, Reporting, Verification) is the EU’s data-collection regime for maritime CO₂ — the prerequisite to EU ETS. Operators submit verified voyage-level emissions data through the EC’s THETIS-MRV system every year.Who it applies to
Ships 5,000 GT and above on voyages calling EU/EEA ports — Regulation (EU) 2015/757.What gets reported
For every voyage in the reporting year:- Departure and arrival ports (with UN/LOCODE)
- Distance travelled
- Time at sea, time at port
- CO₂ emissions broken down by voyage segment
- Fuel consumption by type (HFO, VLSFO, LFO, MDO, MGO, LNG, methanol, biofuel)
- Cargo carried
- Voyage classification (intra-EU, into-EU, out-of-EU, non-EU)
What the platform calculates
The platform uses the sameVoyageSegmentService that powers the EU ETS and vessel-detail pages. That means MRV report figures match what you see in the dashboard, voyage-by-voyage, with no separate “report-time” recalculation.
For each voyage segment the report includes:
- Segment ID (e.g.
99W-1,99W-2for repeated voyage numbers) - Start/end timestamps
- Departure and arrival ports + UN/LOCODE
- Voyage type (INTRA_EU / INTO_EU / OUT_OF_EU / NON_EU)
- Total CO₂ for the segment
- Total distance for the segment
- Fuel-mix breakdown for the segment
- Record count (data-quality flag)
Output
A JSON-format EU MRV report at/api/reports/eu-mrv/[imo]?year=YYYY, plus a downloadable PDF version from the Reports hub. The data structure is THETIS-MRV-compatible.
