The two papers submitted to the IMO present a comprehensive case for recognizing ethanol as a distinct marine fuel with its own technical characteristics, rather than automatically applying requirements developed for methanol. They explain why ethanol and methanol differ in key aspects of safety and how those differences can be reflected in future international regulations.
As shipping moves toward a broader range of low-carbon fuels, international regulations will need to remain robust, technology-neutral, and proportionate to the characteristics of each fuel. These papers contribute to that discussion by outlining a practical, risk-based framework that maintains high safety standards while supporting the safe and scalable deployment of ethanol as a marine fuel. They represent an important step toward establishing a dedicated international regulatory pathway for ethanol within the IMO framework.
