According to the International Council on Clean Transportation (ICCT), the world’s largest and most efficient cruise ships emit about 250 grams of carbon dioxide (gCO2) per passenger kilometer. A five-night, 1,200 mile cruise produces around 1,100 lbs of CO2 emissions.
Cruise ships are giants of the seas, carrying thousands of passengers. But, they also bring something not so nice: emissions. In this article, we explore how much pollution these vessels really produce.

The Shocking Numbers Behind Cruise Ship Emissions
Cruise ships are known for their fun and luxury. Yet, their environmental impact is large. The emissions they release include carbon dioxide (CO2), sulfur oxides (SOx), and more.
| Emission Type | Amount Per Day |
|---|---|
| CO2 | Approx. 150,000 kg |
| SOx | Approx. 7,000 kg |
| Nitrogen oxides (NOx) | Approx. 5,000 kg |
| Particulate matter | Approx. 475 kg |
A big cruise ship can release as much CO2 in one day as 25,000 cars!
Why Are Cruise Ship Emissions a Problem?
The gases and particles from ships harm the air and our health. They can cause problems like lung diseases and heart issues.
- CO2 adds to global warming.
- SOx can make acid rain.
- NOx can make smog and acid rain.
- Particulate matter can harm our lungs.
Living near port cities can mean breathing dirtier air. Tourism spots suffer, too. They deal with the smoke from the giant ships.
Regulations and the Path to Cleaner Cruises
Many agree: we need to make cruise ships cleaner. The International Maritime Organization (IMO) makes rules for cleaner seas.
Here are the steps being taken:
- Using cleaner fuels with less sulfur.
- Installing scrubbers to clean exhaust gases.
- Exploring alternative energy like batteries and solar power.
Cruise lines are also building greener ships. These ships pollute less. But, there’s still work to do.
What Can We Do?
As travelers, we can make a difference. Choose eco-friendly cruises when possible. Ask cruise lines about their green policies.
Eco-friendly cruises might:
- Use LED lighting and low-flow toilets.
- Recycle and compost waste.
- Support shore power, reducing emissions at port.
Let’s make our vacations greener. Happy travels and blue skies!
Frequently Asked Questions
How Do Cruise Ships Impact The Environment?
Cruise ships contribute to air and water pollution, releasing significant amounts of CO2, sulfur oxides, and other pollutants that harm marine ecosystems and affect air quality.
What Is A Cruise Ship’s Carbon Footprint?
The carbon footprint of a cruise ship is substantial, with each vessel emitting thousands of metric tons of CO2 annually, comparable to several thousand cars.
Can Cruise Ship Emissions Affect Climate Change?
Yes, cruise ship emissions contribute to climate change by releasing greenhouse gases like CO2, which trap heat in the atmosphere and drive global warming.
Are Cruise Lines Taking Steps To Reduce Emissions?
Cruise lines are increasingly adopting measures such as fuel-efficient engines, scrubber systems, and alternative fuels like LNG to lower their environmental impact and emissions.
