What is this?
The Flight Carbon Footprint Calculator estimates the CO₂ equivalent emissions produced by your flight based on distance, cabin class, and number of passengers, then compares your impact to familiar everyday activities like driving and home energy use.How to use
Enter your one-way flight distance in miles, select cabin class, choose one-way or round-trip, and enter the number of passengers in your group. The calculator shows per-passenger and total group emissions in kg and metric tons, plus estimated carbon offset costs.Tips
- Economy class produces 2–4× fewer emissions per seat than business class because premium seats occupy more cabin space and weight.
- Short-haul flights are disproportionately polluting per mile — takeoff and landing consume far more fuel than cruising altitude.
- Nonstop flights emit 20–50% less CO₂ than connecting flights because each takeoff and landing burns extra fuel.
- Pack light: airlines estimate each 15 lbs of luggage increases fuel consumption by roughly 1%.
- Carbon offsets typically cost $10–$30 per metric ton; look for Gold Standard or Verified Carbon Standard certified projects.
- For trips under 300 miles, trains emit 70–80% less CO₂ and often take similar total travel time including airport security.
- Consolidating multiple short trips into one longer trip is more fuel-efficient per mile flown.
