Higher taxation is probably the most realistic we can get. I do wonder if it would succeed in actually limiting the amount of flying done. The cost of an all-inclusive trip to the Turkish coast by plane should become high enough for tourists to consider the alternatives. The taxation level should be somewhat dynamic and simply rise or fall to discourage flying as much as is needed to remain below a predetermined yearly ceiling of Revenue Passenger Miles (RPM). On the bright side: in recent years train travel in Europe has been getting better, with a renewed interest in sleeper trains. I just hope this whole Covid-mess doesn't stop these developments completely.
