> Argument is the externalities of carbon emissions have (negative) value, so a tax would bring those two things in line and encourage that only people who really need to fly do so.

If we charged $100-200 per ton of CO2, which is supposedly more than recapture would cost, that would only be about $1-2 per 50 miles. From the numbers being quoted here, it sounds like that would do very little to bring prices in line.




EU is already trading CO2 at 60€/t.


In a limited way, sure. But with massive quotas that are free. That's the price of the very easiest CO2 to deal with, and the rest pollutes for free.

Either charge for all the carbon, or start harshly dropping the quotas.
