About this calculator
This calculator estimates the carbon footprint of domestic flights, i.e., the amount of carbon dioxide (CO₂) emitted per passenger on a flight within Brazil. The result is obtained by multiplying the distance traveled by the average emission factor of 0.255 kg of CO₂ per passenger per kilometer. This value considers typical occupancy and fuel consumption of aircraft used on national routes.
You can use the calculator when planning a trip to compare the environmental impact with other means of transport, such as car or bus. It is also useful for offsetting emissions, calculating how many trees to plant or carbon credits to buy. Companies can use it for sustainability reports of business travel.
Important caveats: the emission factor is an average; flights with low occupancy or older aircraft may emit more. Additionally, the calculator does not include takeoff and landing emissions, which are higher per kilometer. The result is approximate, serving as a reference for awareness and decision-making, not for legal or fiscal purposes.
Frequently asked questions
What formula does the calculator use?
The calculator multiplies the flight distance (in km) by the factor 0.255 kg CO₂/pax/km. For example, a 1000 km flight results in 255 kg of CO₂ per passenger.
Does this factor consider only CO₂ or other pollutants?
The factor considers only CO₂, the main greenhouse gas from aviation. It does not include water vapor, nitrogen oxides, or altitude effects, which can amplify the impact.
How is the distance calculated?
The distance is usually the direct air route between airports, not the road distance. You can enter the distance in km or use departure and arrival cities for an estimate.
Can I use the calculator for international flights?
No, the 0.255 factor is specific for Brazilian domestic flights. International flights have different factors due to longer distances and aircraft types.
What should I do with the result?
You can use the value to offset your emissions by planting trees, buying carbon credits, or choosing less polluting transport for future trips.
