The U.S. could develop high speed rail to avoid use of aircraft. Aircraft could be based on H2. Because of the low specific gravity of H2, that would mean devoting more space to storage of H2. That would increase the price, which itself is a fine way to moderate use of air travel and gratuitous transportation.

I mean, airlines (and airplane mfgs) aren't the most earth friendly enterprises, at their core. Even if we could magically swap out a zero emissions fuel (which we can't: https://www.wri.org/insights/us-sustainable-aviation-fuel-emissions-impacts), we will still see door plugs popping out because we can't be bothered to check every little nook and cranny just to save a few measly human lives. (Why do we freak out so much when an airplane goes down? So many more people die horribly in other circumstances.) This entitled fetish we have for synchronous meatspace interactions makes for a more efficient target. Powering your internet bandwidth with more sustainable electricity is way more likely to reduce emissions than biofuel ever will.
