I think it would be appropriate and entirely rational if scheduled aircraft flying over the GLA area paid a pollution charge in much the same way that road vehicles pay charges in the GLA's current and proposed vehicle charging zones. Because many aircraft take-off from within the GLA area (such as from Heathrow and City Airports) they burn a huge amount of fuel per mile per passenger within this area and are therefore highly polluting in terms of both noise and emissions. It therefore seems paradoxical that they do not pay the same type of charges as road vehicles, in fact they do not even pay any tax on the fuel they burn, so surely it is time to recognise the pollution they cause. I would suggest to the GLA that a charge of around £5 per seat per flight should be levied in order to bring the charging in line with the vehicle charging zones. One strength of this scheme would be that collecting the tax would be easy as details of scheduled flights are always known in advance, there are relatively few carriers and the seating capacity of each aircraft is easy to determine. According to Heathrow, the airport is congested by demand for flights so this could also be regarded as a type of congestion charge which could reduce the need for further spending on infrastructure by limiting further growth.
