Online CO2 calculator for travel by plane


By filling in the required information, the calculator below can be used to estimate the CO2 emmisions from your travels by plane.
Additionally, it compares with emissions from alternative ways of travel.

How long is your flight?

  Kilometer Miles

Choose the actual class of your seat:

Economy BusinessFirst class

Not sure how far you are going?   See Driving distance between European cities and Flight distances between cities in and between different continents.
Unit converter, for conversion to and from non-SI units

A few words about the assumptions for the calculator:

  • The calculations are based on the average of todays aircraft fleet. The most modern aircrafts might have 15-30% less fuel consumption, giving similar less CO2 emissions.
  • Average utilization of plane seats is 60-70%, and the calculations are based on average values. Airplanes that are 100% filled will have lower CO2 emissions than shown by the calculator.
  • For trips shorter than 750 km (466 miles), the same and average CO2 emission numbers are used for all seat classes.
  • For alternative ways of travel based on electric power (trains and el cars), the CO2 emissions are strongly dependent on the energy source. The calculator uses "medium CO2 electricity", which is an even blend of non-emission electric power and power from power plants fired with hydrocarbons (gass, oil or coal). See CO2 calculator - emissions from trains for more detailed calculations based on different energy sources.
  • In comparison with alternative ways of travel, the efficiency regard to distance is set to be:
          Plane: 1 (reference - and the most efficient)
          Car:    1.23 km/km with plane
          Bus:   1.27 km/km with plane
    Train:  1.33 km/km with plane
    (The difference is due to more straight driving lines for planes)
