IMO and sustainable fuels criteria
Alternative marine fuels come with different well-to-wake (WtW) GHG footprint. Currently there are no fuels in production that can deliver zero GHG on a life-cycle basis. But some renewable fuel pathways do have the potential to eventually reach that target, while others will always have substantial residual emissions in the production chain.

To provide certainty for renewable fuels that could theoretically deliver IMO Revised Strategy’s mid and long-term decarbonisation objectives – while minimising the risks of stranded assets for the fuel and technology options that cannot – it is essential to introduce a robust GHG reduction criteria to the definition zero and near-zero emission fuels . We propose introducing the following transitional GHG reduction thresholds to qualify as such.
Sustainable fuels are electrolytic hydrogen-derived fuels that deliver:
- At least 90% WtW CO2e emissions reduction relative to the fossil fuel baseline from 2030 onwards, or a maximum of 9.4 g CO2e /MJ of energy GHG intensity;
- At least 95% WtW CO2e emissions reduction relative to the fossil fuel baseline from 2040 onwards, or a maximum of 4.7 g CO2e /MJ energy GHG intensity;
- 100% WtW CO2e emissions reduction from 2050 onwards.
Such a definition would ensure that only the fuels with long-term full decarbonisation potential, especially those derived from electricity, are promoted through the IMO GFS without prescribing the specific type of on-board conversion tech.
