As of January 1, 2026, Clarksons' data reveals that alternative fuel capability in the shipping sector is primarily found in the orderbook, with 2,036 ships (26% by vessel count, 47% by gross tonnage) ordered, compared to 2,756 alternative fuel-fitted vessels in the active fleet (2% by vessel count, 9% by gross tonnage). LNG-fitted ships dominate the alternative fuel category with 1,560 vessels.

The report also highlights 222 ports with active LNG bunkering and 62 under development, along with 285 shore power connections and 25 ports with methanol bunkering. Emissions control equipment is prevalent, with 6,912 vessels equipped with scrubbers (31% of fleet gross tonnage) and 5,563 vessels with NOx SCR/EGR systems. The dataset is considered conservative, as it may not account for all retrofits or reported equipment.
