Flight Carbon Footprint Calculator

Estimate the CO₂ emissions of a flight per passenger.

Flight distance

Travellers

Emission factor (kg/km)

CO₂ emitted 172.5

CO₂ emitted (tonnes) 0.1725

Formula: CO₂ = distance × factor × travellers

Step-by-step with your numbers:

1. Values used:

2. Flight distance = 1,500

3. Travellers = 1

4. Emission factor = 0.115 kg/km

6. CO₂ emitted = Flight distance x Travellers x Emission factor = 1,500 x 1 x 0.115 = 172.5

7. CO₂ emitted = 0.1725tonnes

Did we solve your problem today?

Estimate the carbon footprint of a flight so you can understand and offset its impact.

The math behind it

CO₂ ≈ distance × emission factor × number of travellers. Economy short-haul is roughly 0.115 kg CO₂ per passenger-km.

1,500 km flight → 1,500 × 0.115 = 172.5 kg CO₂.

Why does class matter?

Business/first seats take more space, so emissions per passenger are 2–4× economy.
