This more environmentally-friendly fuel significantly reduces pollutant emissions in the air and fuel consumption in the sea, minimizing the environmental footprint. #cruiseship #cruiseships #cruises #cruisevacation #cruiseholiday #cruisecrew #cruisejobs #cruiseshipjobs #lng #fillerup #princesscruises #sunprincess #environmentfriendly | Cruiseguru
