## How to Calculate Flight Emissions
Air travel emissions depend on distance, cabin class, and the radiative forcing effect at altitude.
### Formula
**CO2 = Distance * 0.44 lbs/mile * Cabin Factor * 1.9 (RF)**
- **0.44 lbs CO2 per passenger-mile** is the commercial aviation average
- **Cabin class**: Economy = 1x, Business = 1.5x, First = 3x
- **Radiative forcing (1.9x)** accounts for contrails and high-altitude effects

Exemple Résolu
A round-trip economy flight of 2,500 miles each way for one person.
- Total distance: 2,500 * 2 = 5,000 miles
- Base CO2: 5,000 * 0.44 * 1.0 = 2,200 lbs
- With radiative forcing: 2,200 * 1.9 = 4,180 lbs
- In metric tons: 4,180 / 2,204.6 = 1.90 metric tons
