Flight Carbon Footprint Calculator
Flight Emissions
Formula
CO2 = Distance x Trip Multiplier x 0.255 kg/mile x Class Multiplier x Passengers. Class multipliers: Economy 1x, Premium 1.6x, Business 2.9x, First 4x.
Frequently Asked Questions
Why does cabin class affect carbon emissions?
Business and first class seats take up more space, meaning fewer passengers share the fuel cost. A business class seat can produce nearly 3x the emissions of an economy seat on the same flight.
How does flying compare to driving?
For short trips, driving is often more carbon-efficient, especially with multiple passengers. For long distances, flying can be comparable to a single-occupancy car on a per-mile basis, but the total distance is usually much greater.
