The world's largest cruise ship embarks on its maiden voyage

The world's largest cruise ship has set sail from Miami, Florida, on its maiden voyage.

About 365 meters long, the ship has 20 decks and can accommodate a maximum of 7,600 passengers. It is owned by the Royal Caribbean Group.


The ship is going on a seven-day trip to the tropical islands. Environmentalists warn that liquefied natural gas (LNG) ships will leak harmful methane into the air.

Although LNG burns cleaner than traditional marine fuels such as fuel oil, there is a risk that some of the gas will escape, causing methane to leak into the atmosphere.

Methane is a much more potent greenhouse gas than carbon dioxide.

"It's a step in the wrong direction," said Bryan Comer, director of the Maritime Program at the International Council on Clean Transportation (ICCT).

"We would estimate that using LNG as a marine fuel emits over 120% more life-cycle greenhouse gas emissions than marine gas oil," he said.

Earlier this week, the ICCT published a report, arguing that methane emissions from LNG-fueled ships were higher than current regulations assumed.
