Why though? Let's imagine we could create an electric plane for example and produce the electricity it uses completely carbon free.

Why would that be an issue? I think this is totally doable, if we desire.

[claudius]

Sure. Do it.

Given that this is apparently possible, there should be no problems with a 1000% carbon tax on non-electric planes starting tomorrow, right?

The only issue I have with that is there may be other engines which are not electric but could still provide the same benefits.
