How do you calculate the volume of emissions from a flight?

For every 1 kg of jet fuel burnt in the operational phase of the flight, approximately 3.15 kg of carbon dioxide is released into the atmosphere.

The total volume of fuel consumed on a flight depends on factors such as the distance travelled, wind speeds, the loading of passengers, baggage, and cargo on the aircraft. For our calculation methods, we use historic fuel consumption to derive carbon dioxide per passenger kilometre.
