Formula used

CO₂ emissions = Distance × Emission factor

Example: 2,000 km flight at 0.15 kg CO₂/km → 300 kg CO₂.

How to use this calculator

  1. Enter Flight distance (km), Emission factor (kg CO₂ per km).
  2. Press Calculate to see your result instantly.

FAQ

Frequently asked questions

Why does the emission factor vary so much by flight?

It depends on aircraft type, seating class, route efficiency, and passenger load — short-haul flights often have higher per-km emissions than long-haul.

Where can I find a more precise emission factor?

Several published flight-emissions calculators and aviation industry sources provide detailed per-route or per-class factors.

Does this account for radiative forcing (higher-altitude effects)?

No, this is a straightforward CO₂ mass estimate — some sources apply an additional multiplier for the broader climate impact of high-altitude emissions.

How can I offset this footprint?

Verified carbon offset programs allow you to fund emissions-reduction projects proportional to your estimated footprint.
