Air Travel Calculator

Use this calculator to estimate the climate footprint of your air travel and better understand the environmental impact of your flights.

Airplanes release most of their GHGs into the atmosphere at high altitude, where they cause more damage. The Intergovernmental Panel on Climate Change recommends multiplying the emissions by 1.9 to account for their full effect.

Greenhouse gas (GHG) emissions related to air travel are calculated by considering the distance traveled and travel class. The conversion factors used to determine GHG emissions are sourced from reliable and up-to-date sources, such as: DEFRA, Conversion Factors 2021: Condensed Set (For Most Users) - Revised January 2022.
