Flight Carbon Footprint Calculator
Flying produces roughly 90 grams of CO2 per passenger kilometre in economy, and business or first class multiplies that several times because the seats occupy far more floor area. The radiative forcing effect of high-altitude emissions makes the climate impact larger still.
