Every kg of CO2 you contribute to pushing out in the atmosphere is a little bit of freedom taken away from the generations coming after you that will have to deal with the consequences.
If airplane flights are inappropriately priced compared to the externalities they cause - which I’d argue is the case, as with any industry powered by fossil fuel - then taxes are a great way to deal with that.
The reactions in this thread really show why I'll never want to become a politicians. Half of the reactions here are "that's a regressive tax that'll kill our freedom", the other half being "that's not nearly expensive enough".
We may be at the point where we have to choose between the freedom to fly and the freedom to live on an inhabitable planet.
Generations from now, people will, if there are any left, look back on these bourgeois luxuries as a kind of grotesque oppulance, utterly out of whack with ecological reality.
The fact that airplane fuel wasn't as heavily taxed as gas was actually one of the arguments of the gilets jaunes. "We're poor and we can't buy gas to go to work, meanwhile rich people fly to the Caribbeans with subsidized fuel."
Keep in mind that, AFAIK, traveling by plane is significantly more mainstream in the USA (probably due to the huge distances and lack of viable alternatives) than it is in Europe and specifically in France.
The protest that originated "gilets jaunes" was because the increase in gasoline price would affect low wage workers for which their car was one of the main tools for their job.
I cannot imagine many low wage workers that depend on international flights to take home some bread...
I think Yellow Jackets won't mind so much because they are defending the poor people, against raising fuel price just to save 0.001 degree in 100 years.
I don't think they will perceive this as hitting the population they defend.
My biggest problem is it's so low. 1.5/3 Euro for EU/non-EU travel.
