the aviation industry......shows little enthusiasm to address the problem.
Quite to the contrary. Fuel consumption is the key to profitability in a competitive market, with 100 passenger miles per US gallon at 500 mph as the starting point for scheduled jet services. Add to that the fact that the plane does not have any footprint between its destinations (how much fuel is burned to produce a mile of road? No annoying, energy-consuming street lights or "road improvement works" in the sky....) and you might wonder why we still use road transport at all!
