2. All Car figures assume an average car occupancy rate of 1.6 passengers (Carbon Pathways Analysis, 2008, Department for Transport)
3. The long haul estimate is based on a flight length from the Guidelines of of 6482 km, short haul 1108km and domestic 463km.
4. In keeping with evidence from the IPCC, a 9% upflift factor has been applied to allow for sub-optimal routing and stacking at airports during periods of heavy congestion
