Emission factor summary

Emission intensity of domestic flight (within UK) for average passenger excluding fuel combustion and radiative forcing (RF) effect reflecting impact of contrails and high-altitude release of GHGs but not upstream fuel emissions. 8% distance uplift applied for indirect nature of flights.
