Are cruise ships more polluting than planes?

Cruise ships vs. planes: Which pollutes more?

Okay, so thinking about travel and, you know, the planet. It gets a bit confusing sometimes, doesn't it. I was looking into cruise ships versus planes, and honestly, my first thought was, "Surely planes are worse." Big metal boxes flying through the air, that has to be heavy on emissions.

But then I dug a little, and it's not as straightforward as I first imagined. It turns out, a five-day cruise, even on one of those newer, supposedly "eco-friendly" ships, can rack up around 500 kilograms of CO2. That's, like, a lot.

And get this, that 500 kg figure? It’s roughly double what you’d emit from a plane flight for the same amount of time. I remember a trip I took, a short hop over to France a few years back, and I’m pretty sure the emissions for that flight were way less than what they're saying a cruise can generate.

It makes you wonder, right. You picture the vastness of the ocean and think of a ship gliding along, but those things are massive. They have to power everything onboard – the lights, the kitchens, the air conditioning for all those passengers. That’s a huge energy demand.

So, yeah, if you’re weighing it up, the cruise ship seems to have a bigger carbon footprint, at least for a comparable trip duration. It’s a bit of a mind-bender when you think about it, how that slow-moving giant can be more polluting than a speeding jet.

Cruise ships vs. planes: Cruise ships pollute more per person for a five-day trip. CO2 emissions: A 5-day cruise generates about 500 kg of CO2 per person. Comparison: This is roughly double the emissions of a comparable airplane flight.
