The number of dual‑fuel container ships and vehicle carriers in operation has climbed to 400 as of December 2025, almost doubling from 218 a year earlier, according to the World Shipping Council's latest Dual‑Fuel Fleet Dashboard.

WSC's Dual-Fuel Fleet Dashboard tracks the global liner shipping industry's investment in new ships capable of running on renewable and lower emission fuels, and showing how the fleet is preparing for the energy transition.

The number of dual-fuel ships on order has also continued to grow, reaching 726 vessels despite a flurry of deliveries shifting from the orderbook onto the water. Across the containership and vehicle carrier orderbook, 74% of vessels on order are dual-fuel.

In total, WSC said 1,126 dual-fuel containerships and vehicle carriers are now delivered or on order — an increase of 28% compared with last year. This represents over US$150 billion of investment by the liner shipping industry in these new vessels.

"The expansion of the dual-fuel fleet reflects the scale of investment underway across the liner shipping industry," WSC said.

"These vessels are build for the fuel transition, with the capability to switch to renewable and near-zero fuels as they become commercially viable and available at scalem" it added.
