ABS: Efficiency, not Fuel Choice, Key to Shipping Decarbonization

ABS: Efficiency, not Fuel Choice, Key to Shipping Decarbonization The American Bureau of Shipping shared a revised perspective on the decarbonization landscape during a panel discussion held immediately prior to SMM 2026. Its key takeaway: progress does not depend on choosing the optimal fuel type, but rather on sound capital allocation, readiness for various future pathways, investment in workforce and operational capacity, and a commitment to ongoing flexibility. Currently, the market for alternative fuels is shaped by a tough commercial reality, with charterers favoring the most affordable quality option. One shipowner informed ABS that over the last three years, not a single client had agreed to pay beyond what is strictly required by regulation. Rostom Merzouki, ABS Vice President for Sustainability, noted that while the industry aspires to cut emissions, very few customers are prepared to pay a substantial extra cost for it. This means there is no assurance that more environmentally friendly ships will command higher earnings. Given this environment, efficiency has become the central focus. Vessels that operate inefficiently face immediate financial penalties, not only from higher fuel use. On Asia-Europe routes, FuelEU and ETS expenses can now reach as much as $9 million per ship annually. Outside the European Union, ships with the lowest CII ratings are chartered at reduced rates relative to those with better B ratings, and their sale prices can be lower by as much as 15 percent. Merzouki emphasized that fuel efficiency is the most durable investment available at this time, delivering returns no matter which fuel emerges dominant or what regulations are introduced. Considerable gains can already be realized with current technologies, including wind-assisted propulsion, air lubrication, waste heat recovery, digital tools, predictive upkeep, and improved voyage planning. Realizing these savings depends on organizational readiness, meaning having the personnel and expertise to implement changes, along with a sense of urgency. By 2030, the supply chain for efficiency upgrades could become constrained, as a growing number of operators may need to book drydock slots for fuel-saving modifications. Those who pursue these opportunities in 2027 and 2028 are more likely to obtain favorable pricing and can offset the substantial baseline compliance expenses tied to the IMO NZF, should it take effect. Merzouki warned that companies delaying action in search of greater clarity might find that clarity only arrives once the available capacity has been taken. He also challenged the common assumption that investing in dual-fuel engines is always the best route, noting that, depending on the fuel and the vessel's operating pattern, efficiency investments often offer a more compelling financial case than fuel flexibility that may go underused.
