Enter your From and To airports, select your Trip Type, Flight Class, and Number of Passengers, and the Flight Emissions Calculator will show you the Total CO2 Emissions for your journey — plus CO2 per Passenger, Total Emissions in kg, and how many Trees Needed to Offset your flight's carbon footprint.

We calculate emissions based on flight distance, aircraft type, passenger load factor, and class of service. The calculation includes fuel burn rates, aircraft efficiency, and radiative forcing effects of high-altitude emissions.
Business and first-class seats take up more space and weight, reducing the number of passengers per flight. This means higher emissions per passenger compared to economy class, where more passengers share the total flight emissions.
Carbon offsets are investments in projects that remove or reduce greenhouse gases from the atmosphere. These include reforestation, renewable energy, and conservation projects that help neutralize your flight's carbon footprint.
Our calculations use industry-standard methodologies and average values. Actual emissions may vary based on specific aircraft, weather conditions, and routing, but our estimates provide a reliable approximation for planning purposes.
Yes, include all flight segments in your trip. Each takeoff and landing segment consumes additional fuel, so connecting flights typically have higher total emissions than direct flights of the same distance.
On average, one mature tree absorbs about 48 pounds (22 kg) of CO2 per year. However, tree planting is just one type of offset - other projects like renewable energy or methane capture may be more effective per dollar invested.
Direct emissions are the CO2 released from burning jet fuel. Radiative forcing includes additional warming effects from high-altitude emissions like water vapor and contrails, typically doubling the climate impact of aviation.
