The global fleet of dual-fuel containerships and vehicle carriers has surpassed 500 vessels, with shipowners committing more than $200 billion to ships capable of running on alternative fuels, according to new figures from the World Shipping Council (WSC).
What Happened
The WSC Dual-Fuel Fleet Dashboard shows 503 dual-fuel vessels in service as of September 2026, up 41% from 358 a year earlier. Another 849 ships are on order, bringing the combined total to 1,352 vessels.
WSC President and CEO Joe Kramek said the container ship and vehicle carrier industry has committed over $200 billion to ships that can run on cleaner fuels, with more than 500 already sailing and hundreds more on the way. He noted that the investment is happening, but these ships need commercially competitive alternative fuels to deliver their full emissions-reduction potential.
By deadweight tonnage, alternative-fuel-capable vessels account for 65% of containership orders and 97% of vehicle carrier orders, compared with just 23% across the rest of the global fleet. Orders for conventionally fueled ships have also increased over the past year as the overall orderbook expands.
Background
Dual-fuel vessels are designed to operate on conventional marine fuels as well as alternative fuels, giving operators flexibility as new fuel supplies and infrastructure develop. However, their ability to reduce emissions depends heavily on the availability and cost of cleaner fuels.
The International Maritime Organization's proposed Net-Zero Framework, which would introduce a global marine fuel standard and greenhouse gas pricing mechanism, was postponed in October 2025, with negotiations set to resume later this year. The WSC argues that a global regulatory framework is needed to close the cost gap between conventional fuels and renewable and near-zero-emission alternatives while giving shipowners and fuel producers the certainty needed to invest. Without an international agreement, the industry faces the prospect of an increasingly fragmented system of regional emissions rules, adding costs and complexity to global shipping.
The IMO is scheduled to hold its next Marine Environment Protection Committee meeting from November 30 to December 3, with a possible resumed session on the Net-Zero Framework on December 4.
Impact on Shippers
For cross-border e-commerce sellers and exporters shipping from China to the U.S., the dual-fuel transition will not directly change freight rates in the short term, but it will affect the medium- to long-term cost structure. As newbuildings are delivered, higher capital expenditure and fuel procurement costs for carriers may gradually feed through to freight rates via fuel surcharges. If the IMO Net-Zero Framework is eventually adopted, stricter global marine fuel standards could widen the price gap between low-sulfur and alternative fuels, and shippers should watch the pace of surcharge adjustments.
On transit times, bunkering arrangements for dual-fuel ships may affect port calls and transshipment efficiency on some routes, especially at ports where alternative fuel infrastructure is not yet mature. Customs clearance itself is not directly affected by vessel fuel type, but if carriers adjust routes or schedules for environmental compliance, shippers should build buffer time into pickup and container return plans.
Recommendations
Shippers should monitor carrier announcements on fuel and environmental surcharges and factor potential surcharge volatility into ocean-parcel and ocean-truck delivery cost budgets. For time-sensitive cargo, confirm vessel schedules and transshipment port arrangements with freight forwarders in advance to avoid delays from bunkering or route adjustments. Keep an eye on IMO meeting outcomes; if a global framework makes substantive progress, assess cost clauses in long-term transport contracts early. Specific rates and rules are subject to the latest carrier and official announcements.
