Choose a flight that generates fewer emissions, or a flight company committed to the environment.

What does CO₂ signify in flights?

Excessive CO2 emissions from flights can exceed the absorption capacity of forests, oceans, and other natural sinks. This highlights the value of efforts to reduce CO₂ emissions that some airlines are implementing.

How to fly more sustainably?

1. Calculate your carbon footprint.
2. Choose airlines that are committed to the environment.
3. Reduce stopovers.

Flights contribute CO₂ to the atmosphere due to the release of water vapor and nitrous oxide, in addition to other greenhouse gases, during the burning of airplane fuel.

The International Civil Aviation Organization (ICAO) has developed a carbon emission calculator that estimates your footprint when traveling by plane.

An airplane uses more fuel during takeoffs and landings. Fewer stops means a reduced carbon footprint.

Cheaper seats help increase a plane’s efficiency. On the other hand, occupying a first-class seat can quadruple a passenger’s carbon footprint. Traveling light helps reduce the weight on the plane.
