The International Council on Clean Transportation has published a white paper that defines what counts as an ultra-low-carbon fuel for a potential green shipping corridor along the U.S. West Coast. The definition sets an emissions threshold for fuels like hydrogen, ammonia, methanol, and electrification, with the goal of giving regulators and fleet operators a common standard to work from. The paper also links to a related ICCT study on Jones Act shipping, which looks at whether hydrogen fuel and wind assist can work for domestic routes. Anyone tracking maritime decarbonization policy or fuel procurement rules will want to read the threshold proposal closely, because it will likely shape what gets funded and approved.
