Okey, rephrasing.
There is a demand from the public that the airline industry should show good will to fly more environmentaly.
The public and the governments will support those airlines that adapt as many fuel/noise/carbon lowering measurements as possible. A small step as a whole, but a giant step in our business.
I also know that there are political discussions that atc will favour airlines with upgraded equipment to land in advance, if they use curbed approaches. And there is more to come...
Now, ten criterias to use, benchmarking airlines, finding out who does the most.
Donīt be a cynic.
