Ship CO2 emissions under EU MRV
Every ship above 5,000 gross tonnes that calls at a port in the European Economic Area has to measure its fuel and its CO2, have the figures verified, and file them. The European Maritime Safety Agency publishes the result as one spreadsheet per year. This is that spreadsheet as pages: one per ship, one per company, and a line per reporting year on each of them.
| Reporting year | Ships | Companies | CO2 | Fuel |
|---|---|---|---|---|
| 2025 | 17,450 | 4,278 | 151.8 million t | 49.1 million t |
| 2024 | 14,185 | 3,610 | 147.2 million t | 47.6 million t |

| 2021 | 12,485 | Not named | 126.8 million t | 40.7 million t |
| 2020 | 12,118 | Not named | 129.7 million t | 41.6 million t |

What the numbers cover
EU MRV scope is voyages that arrive at, depart from or run between ports in the European Economic Area, plus emissions at berth there. A ship that spent half its year in Asia files only the European half, so these figures are never a full annual footprint and should not be read as one. Emissions are verified by an accredited verifier before filing, and the verifier is named on every ship page.
The source names the company that held the Document of Compliance only from the 2025 reporting period onward. Earlier years carry the ship and the verifier but no company, which is why the company column above reads as not named for those years and why no company page covers them.
Where this comes from
The European Maritime Safety Agency publishes one versioned spreadsheet per reporting period at mrv.emsa.europa.eu. We read it, keep the columns that carry meaning, and record the exact versioned file every row came from, so any figure here can be checked against the original. The version climbs through the year as ships file late, so these pages are rebuilt whenever the published version moves.
