Frequently Asked Questions

How are the emissions calculated?

CO₂e (kg) = Flight Hours × Fuel Burn Rate (gal/hr) × 9.57 kg CO₂/gal

Where does the aircraft data come from?

The data used to estimate gallons per hour aircraft data, including fuel burn rates and cruising speeds, is sourced from manufacturer specifications and industry averages.

What assumptions are made?

• • Single occupant flights for simplicity
• • Average cruising speed for each aircraft type
• • Standard atmospheric conditions
• • Constant fuel burn rate during cruise

How accurate are these calculations?

While our calculator provides a good approximation, actual emissions may vary based on specific flight conditions, aircraft configurations, weather, and other operational factors.
