The Carbon Footprint of Major Travel Methods Revealed

{Carbon Footprint – Here we reveal the carbon footprint of major travel methods.  The most striking revelation is how very inefficient and polluting it is to travel alone in a big fuel thirsty car – Earth and Leaf editorial}

The carbon footprint of major travel methods revealed

Did you know that transport accounts for nearly one-quarter of global energy-related carbon dioxide (CO₂) emissions?

This graphic illustrates the carbon footprint of major travel methods measured in grams of carbon dioxide equivalent (CO₂e) emitted per person to travel one kilometer. This includes both CO₂ and other greenhouse gases.

Data is sourced from Our World in Data, the UK Government’s Department for Energy Security and Net Zero, and The International Council on Clean Transportation, as of December 2022.

These figures should be interpreted as approximations, rather than exact numbers. There are many variables at play that determine the actual carbon footprint in any individual case, including vehicle type or model, occupancy, energy mix, and even weather.

According to these estimates, taking a cruise ship, flying domestically, and driving alone are some of the most carbon-intensive travel methods.

Cruise ships typically use heavy fuel oil, which is high in carbon content. The average cruise ship weighs between 70,000 to 180,000 metric tons, meaning they require large engines to get moving.

These massive vessels must also generate power for onboard amenities such as lighting, air conditioning, and entertainment systems.
