FuelEU Document Update: GUIDELINES FOR REPORTING AND VERIFICATION OF ACTUAL METHANE SLIP TANK-TO-WAKE EMISSION FACTORS FROM MARINE DIESEL ENGINES UNDER THE SCOPE OF FUELEU MARITIME REGULATION

A New Chapter in Maritime Climate Action

The European Commission has introduced detailed guidance for measuring and verifying methane slip from marine diesel engines. This development marks a milestone in the journey toward transparent, science-based emissions reporting under the FuelEU Maritime Regulation.

Methane is a potent greenhouse gas, and controlling its release from ship engines is now a key step in reducing the climate footprint of the maritime sector. These guidelines bring much-needed clarity to how companies can report and verify actual emissions instead of relying on default estimates.

What the Guidelines Introduce

The document outlines procedures for monitoring methane emissions through real operational data. It allows operators to use laboratory testing and continuous emissions monitoring systems while ensuring consistency with international standards such as IMO Resolution MEPC.402(83).

Ship operators must maintain records of engine performance, conduct annual verification checks, and report maintenance on methane abatement systems. By doing so, they can ensure that real-world operations align with environmental goals and regulatory requirements.

Moving Beyond Compliance

The new framework is more than a compliance tool. It enables data accuracy, encourages innovation in monitoring technologies, and helps shipping companies demonstrate leadership in emissions transparency. As the sector prepares for global decarbonisation, this focus on methane accountability strengthens confidence among regulators, financiers, and consumers alike.

Conclusion

These guidelines represent progress not just in regulation but in trust and responsibility. By focusing on measurable impact, the maritime industry takes another step toward a cleaner and more efficient future.
