Short-haul flight <700 km - RF effect unknown

Emission intensity WTT of an international flight (to/from non-UK countries) for an average passenger excluding radiative forcing (RF) effect reflecting impact of contrails and high-altitude release of GHGs. WTT conversion factors for passenger vehicles and business travel on land should be used to report the upstream Scope 3 emissions associated with extraction/refining and transportation of the raw fuels before they are used to power the transport mode. While the source does not mention it explicitly it is inferred from the methodology that 8% distance uplift is applied for the indirect nature of flights.
