Maritime Biofuel Rules Must Balance Bankable Demand and Lifecycle Risk
Maritime decarbonization will depend less on choosing a single replacement fuel than on whether global rules can create bankable demand while distinguishing genuinely lower-carbon supply chains from those that shift emissions elsewhere, the speakers argue. Rod Snyder said shipping is headed toward a multi-fuel future, with U.S. ethanol, woody biomass and e-fuels all seeking a role. But Jennifer Aurandt-Pilgrim’s call to credit documented farm and plant improvements clashes with UC Davis researcher Colin Murphy’s warning that lifecycle standards must also account for indirect land-use change and other market effects beyond a producer’s gate.
