Flight Carbon Footprint Calculator
Estimate the CO2-equivalent emissions of a flight from its distance and cabin class. Premium cabins have higher per-passenger footprints because each seat takes more space on the plane.
Inputs explained
- Flight distance — The flight distance in kilometres (great-circle distance between airports). London to New York is about 5,570 km.
- Cabin class — Economy, premium economy, business, or first — emission factors range from 0.15 to 0.60 kg CO2e per km.
- Passengers — How many travellers to include in the total.
How to use it

Understanding the result
Example: A 1,000 km economy flight emits roughly 150 kg CO2e per passenger (1,000 km × 0.15 kg/km).
Frequently asked questions
Why does flying business or first class have a bigger footprint than economy for the same route? Premium cabins use more physical space and weight per traveler on the aircraft, so the plane's total emissions are divided among fewer effective passengers per row, raising the per-passenger share.
Does the estimate change based on the specific aircraft or airline? No, it uses a general per-kilometer emissions factor by cabin class rather than aircraft-specific fuel burn data, so actual emissions can vary by plane type and route efficiency.
