Accounting for fuel oil consumption

Interim Guidance for the use of biofuels

The Marine Environment Protection Committee (MEPC) of the Internationale Maritime Organization IMO recently approved "Interim guidance on the use of biofuels under regulations 26, 27 and 28 of MARPOL Annex VI" (MEPC.1/Circ.905). This Interim Guidance assists with the calculation for DSC reporting and the Carbon Intensity Indicator (CII) in cases where biofuels are used on board seagoing vessels.

The Interim Guidance enters into force on 1st October 2023. It applies until more comprehensive guidelines for well-to-wake GHG emissions have been developed and entered into force.

The Circular MEPC.1/Circ.905applies immediately for seagoing ships flying the German Flag and can already be applied for the 2023 monitoring period.
