Flight Carbon Footprint Table: CO₂ emissions by Flight distance

Reference table of co₂ emissions for Flight Carbon Footprint across a range of flight distance values — exact, engine-computed figures you can read off at a glance.

How to use this table

Find the row closest to your flight distance and read across to the co₂ emissions. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Flight Carbon Footprint Calculator for a precise answer.

Need a value that is not in the table? — the Flight Carbon Footprint Calculator does it instantly, for free, with the formula and a worked example built in.
