All renewable and low-carbon fuels that meet the criteria specified in FuelEU Article 10, and are used during international voyages, contribute to the GHG intensity of half the energy used during those voyages. This applies up to the maximum energy amount defined under FuelEU Maritime Article 2(1)(d).
Similarly, this provision applies to such fuels used on voyages arriving at or departing from a port of call located in an outermost region under the jurisdiction of a Member State, as outlined in FuelEU Article 2(4).

Although fuel consumption must be reported on a “per voyage” basis, the calculation of the average yearly GHG intensity of the energy used onboard is based on the total mass of fuel used per energy consumer over the course of the year.

Examples of Renewable and Low-Carbon Fuel Usage under FuelEU Maritime Regulation
Use of Bio-Blend B30 (30% biodiesel + 70% fossil diesel):
The entire biodiesel fraction (30% of the blend) can be counted towards the energy used during an international voyage.

Use of Bio-Blend B60 (60% biodiesel + 40% fossil diesel):
A portion of the biodiesel fraction (up to 60% of the blend) can be counted towards the energy used during an international voyage, but only up to the maximum energy amount specified under the scope of the Regulation.

This is an illustration how different proportions of biodiesel in bio-blends can be counted towards the GHG intensity targets during international voyages, in accordance with the FuelEU Maritime Regulation.
