The total sales of aviation fuels in the UK in 2006 was 12.7 million tonnes ĬO 2 emissions from aviation fuel are 3.15 grams per gram of fuel. The CO 2 emissions are therefore rounded up and the Carbon Independent calculator takes a values of 250 kg i.e. airport construction, maintenance, heating, lighting etc.aircraft manufacture and maintenance, and staff training.inefficiencies in refineries (around 7% ).The emissions are therefore adjusted by multiplication by a factor of 2.00 (see 'Radiative forcing' below) to give 180 kg CO 2 equivalent per hour.įurther allowance is needed for fossil fuel energy used in :

These CO 2 emissions are generally into the high atmosphere, and this is thought to have a greater greenhouse effect than CO 2 released at sea level. So for both aircraft, the emissions are around 90 kg CO 2 per hour. The corresponding figures (same sources) for a Boeing 747-400 (used for long distance international flights) are: Using a seating capacity of 164 and an average seat occupancy (or 'load factor') of 65%, this gives a fuel use of 36.6 g per passenger km.ĬO 2 emissions from aviation fuel are 3.15 grams per gram of fuel, which gives CO 2 emissions from a Boeing 737-400 of 115 g per passenger km.Īt a cruising speed of 780 km per hour, this is equivalent to 90 kg CO 2 per hour. One way to calculate CO 2 emissions is from fuel consumption per flight.Ī Boeing 737-400 jet is typically used for short international flights.įor a distance of 926 km, the amount of fuel used is estimated to be 3.61 tonnes, including taxiing, take-off, cruising and landing. The calculator assumes greenhouse gas emissions of ¼ tonne CO 2 equivalent per hour flying.īasis 1 (from fuel consumption per flight)
