CIMAC WG 7 Fuels | ISO 8217:2024 - Marine-fuels containing FAME: A guideline for shipowners & operators

One of the most readily available ways to decarbonise shipping is the use of biomass derived fuels. The current amount of available biofuel is not sufficient to reach the targets set. It is however a first step and additional technical innovation, and investment will increase the uptake of this decarbonisation pathway. The development of biofuels is therefore ongoing, and more differentiation is expected in the biomass used, processing and resulting qualities. ISO has published a new version of the ISO 8217 Specifications of marine fuels standard and to support this transition it now allows the use of FAME up to a concentration of 100% in specific grades.

This document serves as a guideline for shipowners and operators to safely use biofuels in conjunction with the publication of ISO 8217:2024. It is mainly focused on Fatty Acid Methyl Esters (FAME) and blends with fossil fuel.
