About the Zurich–New York route
The ZRH–JFK route covers approximately 6,330 km great-circle distance between Zurich Airport in Switzerland and John F. Kennedy International in USA. In economy class, each passenger is responsible for approximately 538 kg CO₂ per flight direction, or 1,076 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 1,883 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.
