If we cut carbon out of everything else, the price of oil will drop, and aviation will be able to greatly expand. Air travel is low now only because it's expensive. People world gladly take many, many more flights if they were cheaper. Of course if we taxed carbon this problem would go away, and taxing international flights would probably be easier than a general carbon tax, if flights were all that was left.
