Pardon me for being nieve..or cynical
A properly invested tax will have a very positive effect if put into public and private R&D

1p for a ticket...then £15.00 in airport charges..of which 50% go to the government....750%
My point being that depending upon which way you want to play the statistics..you can make an argument.
The facts are clear...aircraft are STILL the most carbon efficient (utilizing carbon based fuel) forms of transport known to man.
