CO2 Calculator for Cruises — Measure Your Cruise Carbon Emission Footprint

Introducing the Cruise CO₂ Emission Calculator: Know Your Cruise’s Environmental Impact As cruise lovers, we know how exciting it is to plan a trip on the open seas. But with growing awareness about climate change, it’s time to take responsibility for the environmental impact of our travels. That's why we created the Cruise CO₂ Emission Calculator—a simple tool designed to help you calculate the carbon footprint of your cruise trip, per person, based on the latest scientific data. Our calculator leverages the methodology from myclimate.org, accounting for crucial factors like ship size, passenger capacity, trip duration, cabin type, and occupancy rate. We further finetune the calculation by also taking into account a ships age that correlates with its engine efficiency. By doing so, it provides an accurate estimation of CO₂ emissions. Importantly, we go beyond just CO₂; other pollutants such as methane, nitrogen oxides, and sulfur oxides are factored into the result, giving you a complete picture of your cruise's environmental footprint. One surprising insight from our calculator is that larger ships often have lower CO₂ emissions per passenger compared to smaller vessels. For example, a cruise on Royal Caribbean’s Icon of the Seas with over 7,000 passengers results in lower per capita CO₂ emissions than a cruise on a smaller ship like the Viking Sky. This is due to larger ships’ space efficiency—while they emit more CO₂ overall, they can accommodate far more passengers, distributing the emissions more evenly. By using our tool, you can make more informed, sustainable choices when planning your next cruise. Whether you're opting for a smaller, eco-conscious ship or a larger, more efficient one, our calculator helps you understand your environmental impact. It's also the best basis to offset your emissions via various non-profit organizations. Let us know your feedback in the comments!
