Formula
- Use the units shown beside each field.
- Results update automatically whenever you change an input.
- Displayed values use up to four decimal places, or scientific notation for very small or large numbers. Calculations use standard floating-point arithmetic; exact integer and fraction tools identify their own precision rules.
- No route lookup, aircraft model or standard non-CO₂ uplift is assumed. Avoid double-counting if the factor already includes extra effects. Scenario calculation using your supplied factors. Defaults are illustrative inputs, not verified regional or product-specific measurements.
Example Calculation
- One-way distance: 1000 km
- Flight legs: 2
- Passengers: 1
- Factor per passenger-km: 0.1 kg CO₂e/passenger-km
- Additional impact multiplier: 1
Two 1000 km legs for one passenger at the entered 0.1 kg/passenger-km and multiplier 1 total 200 kg.
Frequently asked questions
How do I use this calculator?
Enter one-way distance, flight legs, passengers, factor per passenger-km, additional impact multiplier. The result updates automatically. Use Reset to restore the example values.
What method does it use?
impact=distance × legs × passengers × factor × multiplier.. No route lookup, aircraft model or standard non-CO₂ uplift is assumed. Avoid double-counting if the factor already includes extra effects. Scenario calculation using your supplied factors. Defaults are illustrative inputs, not verified regional or product-specific measurements.
Why might a rounded result differ?
The calculation keeps full numeric precision internally, then rounds the displayed result. Rounding intermediate steps by hand can produce a slightly different answer.
Are my inputs saved online?
No. This calculator processes your inputs in your browser. A recently used list stores only calculator names on this device, not your entered values.
