Sustainable LNG cruising is a lie, anyway. It's just greenwashing. Companies that claim to reduce their emissions by switching to LNG are giving misleading information, as LNG still is a fossil fuel.
For a cruise in Europe for example, large LNG carriers first have to transport the liquid gas from the U.S. (the worldโs largest LNG exporter). And these carriers run on regular, super dirty heavy fuel oil. ๐คฃ
