Every cruise is a poop cruise when it comes to the environment.
one cruise ship produces roughly the same amount of carbon emissions as 12,000 cars. They’re also poorly regulated.
Mark Jacobson, a professor of civil and environmental engineering at Stanford University, tells Popular Science that the type of fuel cruise ships burn contributes to their many harmful environmental effects. “They generally use bunker fuel, which is the dirtiest type of fuel. Bunker fuel puts out lots of black carbon, sulfates and other chemicals,” Jacobson says. “Black carbon is the second leading cause of global warming after carbon dioxide.
What’s the solution? Cruise ships could just be banned, of course, but Jacobson says there’s a pretty simple technological solution. Like with cars, it’s a matter of transitioning these ships to clean energy. He says ships can be transitioned to batteries or hydrogen fuel cells.
