Am I reading this right? Only a 22% fare increase? For completely decarbonizing air travel? That's less than the price variance of just flying at a different time.
Flying should be rationed.
Another idea: eliminate business travel to attend meetings now that we have amazing remote presence tools.
There's still some arguing about how to price this in accurateley but this was part of the reason that Google changed their GHG measure for flights recently. They previously just averaged it, but ideally want to encourage flights at times when it is less of a problem.
