6,843 km
Car equivalent
Driving a petrol car alone at EU average emissions (0.21 kg CO₂/km). The LHR–MEL flight emits the same as this many kilometres driven.

About the London–Melbourne route
The LHR–MEL route covers approximately 16,910 km great-circle distance between London Heathrow in United Kingdom and Melbourne Airport in Australia. In economy class, each passenger is responsible for approximately 1437 kg CO₂ per flight direction, or 2,874 kg for a round trip — calculated using the ICAO Carbon Emissions Calculator v13.1 methodology with fleet-average aircraft and typical load factors.
Business class passengers on the same route emit approximately 5,030 kg CO₂ per direction — roughly 3.5× more than economy — due to the larger floor area allocated to each business class seat. The climate impact is further amplified by a Radiative Forcing Index (RFI) of 1.9×, which accounts for non-CO₂ effects of aviation at cruising altitude including contrail formation and NOₓ emissions.
