Royal Caribbean Group has collaborated with World Fuel Services to sail its Navigator of the Seas ship using renewable diesel as part of a trial.

With this move, the group is claimed to become the first major cruise company to sail a cruise vessel out of a US port using renewable diesel for at least a portion of its fuel requirements.

The ship is part of the firm’s Royal Caribbean International cruise brand.

Said to contain less carbon than traditional marine fuels, sustainable fuel is produced using renewable raw materials.

On behalf of World Fuel Services, the Jankovich Company will supply the renewable diesel to the ship while it is at the Port of Los Angeles in California.

With plans to expand its usage to other ships across the fleet, the lower carbon fuel will be used to meet part of the Los Angeles-based ship’s fuel requirements.

Following the fuelling, Navigator of the Seas will set sail to Mexico.

The move follows the launch of Royal Caribbean Group’s comprehensive decarbonisation strategy, called Destination Net Zero.

Hapag-Lloyd Cruises, which is the group’s joint venture partner, conducted a similar trial to explore a different process for the development of sustainable biofuel.

Royal Caribbean Group shared services operations executive vice-president Laura Hodges Bethge said: “We are committed to investing in technologies and innovations that will help us reduce emissions and fulfil our purpose to deliver great vacations responsibly.

“As we celebrate this milestone, we continue to set our sights on other leading alternative solutions to meet our net zero goals.”

Separately, Royal Caribbean Group is set to launch the first hybrid-powered cruise ship next summer. This ship will be part of Silversea Cruises’ newest class of ships, the Nova class.
