Flight Carbon Estimator: Distance Times a Class Factor
Flight emissions feel abstract until distance and cabin class are separated. A per-kilometre factor turns a route into a comparable number.
What is the Flight Carbon Estimator?
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.
How to use it
- Enter the flight distance in kilometres.
- Choose the cabin class.
- Enter passengers and click Estimate Emissions.
Worked example
A 1500 km economy flight emits about 135 kg of CO2 per passenger at 0.09 kg per kilometre.
How much CO2 does a 1500 km economy flight emit per passenger?
About 135 kg, at an estimated 0.09 kg per kilometre.
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.
