About this tool
Flight emissions are estimated from distance and cabin class, since premium cabins take more space per passenger. This estimator uses simple per-kilometre factors as a planning figure, labelled as an estimate throughout. Real emissions vary by aircraft, load, routing, and fuel, so treat the result as a comparison guide, not a measured footprint.
Frequently asked questions
Why do premium cabins score higher?
Because premium seats take more floor space per passenger, so each premium passenger carries a larger share of the flight's emissions.
Is this a measured footprint?
No. It is a labelled estimate for comparison; aircraft type, load, and routing change the real figure.
