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.

    1. Total distance: 2,500 * 2 = 5,000 miles
    2. Base CO2: 5,000 * 0.44 * 1.0 = 2,200 lbs
    3. With radiative forcing: 2,200 * 1.9 = 4,180 lbs
    4. In metric tons: 4,180 / 2,204.6 = 1.90 metric tons
