Unintended consequence: you'll penalize shorter flights because achieving altitude is the least fuel efficient part.
As a result, you'll increase travel via car and the net result will be increased pollution at the expense of the economy.
- esotericn 7y agoDriving and flying have approximately the same emissions assuming 1 person in the car. A bog standard 100g/km car would emit 600kg to go 6000km; a passenger flying London-New York also emits approximately the same. (Obviously you can't drive London-NY, it's an example). Short haul, as you say, it tips in favour of the car. Multiple people and it becomes a no brainer. Then take into account the fact that tons of journeys would simply not happen. It's common for people to jet around Europe for weekend trips. No-one would drive that. I have a sense that US domestic flights tend to skew discussion on this.
