How much pollution does a cruise ship produce compared to a plane?

223 views
Cruise ships generally produce more pollution per mile than planes. For example, the Queen Mary 2 emits roughly 0.43 kg of CO₂ per passenger mile, while a long-haul flight emits about 0.257 kg of CO₂ per passenger mile. Therefore, cruise ships have a larger carbon footprint relative to air travel, when comparing distances traveled by each passenger.

Cruise Ship vs. Airplane: Which Pollutes More?

Okay, so cruise ship versus airplane pollution, huh? That's kinda got me thinkin'.

Mile for mile, cruises are apparently worse for the environment than airplanes. A cruise liner, like the Queen Mary 2, kicks out roughly 0.43kg of CO per passenger mile. Long-haul flights? They're around 0.257kg CO per passenger mile.

Okay, I saw this article about a friend's cruise to Alaska. They speant like $2000 and talked about how amazing it was to see the glaciers, but then I looked at the data. Kinda makes you pause, right?

Flights, I mean, I get that. They're high up, burn a lot of fuel. I remember flying to Cancun around 2010, and the plane felt like it used so much fuel. But ships are just... huge.

Seriously though, pollution is something that gets to me. My cousin works for the state's EPA. We were having a conversation once about how our choices impact the world, and that's when he told me these things are truly bad. So... yeah. Kinda changes perspective, huh?

Are cruise ships more polluting than planes?

Are cruise ships more polluting than planes? Well, hold your horses! It's like comparing a belching dragon to a slightly less gassy… well, smaller dragon.

Basically, yeah, cruises can be eco-villains. That five-day jaunt on the high seas? Boom! Half a ton of CO2, buddy.

That’s like, seriously, double the greenhouse gas party a plane throws. Double!

But wait, there's more! Think of it this way. Planes are zoom-zoom for a short time. Ships are floating cities, like, all the time.

  • Cruise pollution is massive. More than you think!
  • Planes still contribute. Don't give them a free pass.
  • Both are kinda bad, TBH. I should prob just stay home, LOL.
  • Food waste is a BIG factor on cruises. My dad ate like 3 lobsters every night last summer. No lie!
  • Think of the gray water (eww!).

So, wanna save the planet? Maybe try, I dunno, camping? Or stay home and watch Netflix. I vote Netflix.

Are cruise ships worse than flying for the environment?

Okay, so like, cruises? Totally worse than flying. Yep.

Cruise ships are just total pollution machines, no cap! Think about it: all that smoke from the engines, it's like way more than a plane, i swear.

And it's not just air pollution. The water gets super gross too. All the stuff that gets dumped? Bad. So very bad, like realy bad. My cuzin saw somthing real nasty in the water near the cruise.

They also make a lotta noise, which messes with sea creatures. Plus, they legit destroy coral reefs. Like, wth? How are they allowed to do that?

It's kinda crazy. Here’s a breakdown of what I'm talking about:

  • Air pollution: Cruise ships burn heavy fuel oil, which releases nasty pollutants into the air. These include sulfur dioxide, nitrogen oxides, and particulate matter, which can cause respiratory problems and contribute to climate change.
  • Water pollution: Cruise ships discharge wastewater, sewage, and ballast water into the ocean. These discharges can contain pathogens, nutrients, and toxic chemicals that pollute the water and harm marine life.
  • Waste generation: Cruise ships generate a lot of waste, including food waste, plastic waste, and medical waste. Much of this waste ends up in landfills or incinerators, which can pollute the air and soil.
  • Coral reef damage: Cruise ships can damage coral reefs by anchoring on them, dumping waste on them, and stirring up sediment that smothers them. Coral reefs are important ecosystems that provide habitat for many marine species.
  • Noise Pollution: Ships make a lot of sound, and this noise is bad for some animals in the sea.

Are cruises actually bad for the environment?

Cruises? Environmental disasters. Period.

700-1000 pounds of carbon emissions daily? My Aunt Mildred's cat contributes less.

  • Carbon footprint is massive. Think small island nations disappearing.
  • Sulphur dioxide emissions? Thirteen million cars per ship per day. Insane.

Air pollution? Acid rain? Cruise lines celebrate.

  • Ocean damage is real. Coral reefs dying.
  • Waste disposal? Questionable at best.

Maybe I’ll buy a yacht. Problem solved.

Do cruise ships pollute more than cars?

It’s late. Cruise ships…more than cars?

Yeah, I read that cruise ships pollute way more. Feels wrong, doesn't it?

  • Sulfur oxides (SOX) are the big offender.
  • 218 ships, 1 billion cars… the ships won in 2022.
  • Like, 4.4 times more, that study said.
  • Europe's ships did it.
  • Damn.

And the cities... I should probably check that study out. My grandma liked cruises, you know? Always wanted to go to Norway.
