EU maritime MRV reform: one unified report from 2029

What the 17 July 2026 proposal changes

On 17 July 2026 the European Commission published a proposal to merge MRV, EU ETS and FuelEU Maritime into a single reporting workflow. The stated goal is one monitoring plan and one report per ship, instead of three separate submissions across three frameworks.

The Commission estimates this unification could cut annual MRV compliance costs by 10 to 20 percent.

For compliance teams, this means fewer duplicate entries, fewer formats to reconcile, and one fuel dataset feeding both the ETS calculation and the FuelEU intensity index. The benefit is not purely administrative: it also reduces the discrepancies between filings that currently trigger audits.

A wider scope from 1 January 2029

The proposal broadens MRV scope to ships between 400 and 5,000 gross tonnage (GT), effective 1 January 2029. This fleet segment, previously below the threshold, needs to prepare well ahead of the deadline.

• General cargo ships
• Tankers
• Gas carriers
• Passenger and ro-pax ships

The proposal also adds safeguards against regulatory evasion through offshore vessels, a point directly relevant to multi-fleet operators managing their exposure to MRV scope.

Renewable fuels: real data over default values

A key point for suppliers: biofuels, biogas, RFNBOs and recycled-carbon fuels could use their actual well-to-tank emission values instead of conservative default figures, provided they are certified under a Commission-recognised scheme.

In practice, better-tracked fuel becomes a measurable commercial advantage in ETS and FuelEU calculations, not just an environmental argument. On technical compatibility, only HVO (EN 15940) is a genuine drop-in maritime fuel; B100 (EN 14214, FAME) is not universally drop-in and requires strict manufacturer compatibility checks before use.

Not yet law, but the time to act is now

The Commission opened an 8-week public consultation period starting 21 August 2026. The proposal is therefore not yet adopted, and its content may still change. Waiting until 2028 to look into it would nonetheless be a scheduling mistake for any compliance team.

The direction is clear: simplified reporting on one side, verified fuel data becoming commercially decisive on the other. Shipowners and suppliers who structure their fuel traceability and monitoring plan now will be better positioned once the text is finalised.
