The ship is also designed to be more energy efficient overall. Some systems help reduce waste and improve water usage onboard. However, there is still debate about how environmentally friendly large cruise ships can really be. Critics point out that even cleaner fuels still produce emissions. The ship includes plans for future upgrades like fuel cell technology. It can also connect to shore power while docked to reduce pollution.
