Calculate an average flight journey!

The environmental impact of aviation occurs because aircraft engines emit heat, noise, particulates and gases which contribute to climate change and global dimming. … In the European Union, greenhouse gas emissions from aviation increased by 87 percent between 1990 and 2006.

This flight emission calculator quantifies the direct and indirect CO2-equivalent emissions per passenger for a given flight distance and it is based on the most recent international statistics on passenger and cargo loads and aircraft type usage.

The estimated emissions per passenger represent the amount of CO2 equivalents to be reduced in special initiative-led carbon offset projects.

Calculation principles

The flight calculator determines the quantity of CO2 emissions that an aeroplane gives off per passenger for a given flight distance. The calculation is based on average consumption data for typical short-haul and long-haul aeroplanes. The computation also takes into account whether you are flying economy, business or first class.
