Passenger taxes are ineffective for reducing CO2
emissions. This is not just because demand is relatively
price insensitive at a national and supra-national
level. It is also because raising the cost of travel
for the passenger does nothing to incentivise the
manufacturer to produce new airframes or engines,
nothing to incentivise the fuel company to produce a
clean fuel, nothing to incentivise the EU to implement
a Single European Sky, nothing to incentivise ANSPs
to straighten routes and reduce stacking, nothing to
incentivise airports to reduce taxiing emissions, and
nothing to incentivise airlines to improve operations
and renew their fleet
