CO2 Emissions (with RF) vs One-Way Flight Distance
公式
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)
计算示例
A round-trip economy flight of 2,500 miles each way for one person.
- 01Total distance: 2,500 * 2 = 5,000 miles
- 02Base CO2: 5,000 * 0.44 * 1.0 = 2,200 lbs
- 03With radiative forcing: 2,200 * 1.9 = 4,180 lbs
- 04In metric tons: 4,180 / 2,204.6 = 1.90 metric tons
常见问题
What is radiative forcing?
Radiative forcing accounts for the fact that emissions at high altitude have a greater warming effect than the same emissions at ground level, amplifying impact by roughly 1.9x.
Why does cabin class matter?
Business and first class seats take up more floor space, so each passenger is allocated a larger share of total fuel burn.
How can I reduce flight emissions?
Fly economy class, choose direct flights, fly less frequently, or purchase verified carbon offsets.
