The first time I heard an aviation ceo spruiking this BS on NPR it was so clear that it was a complete lie. There was no serious attempt by a scientist to quantity emission reductions, just a lot of feel good marketing nonsense.
SAFs are just a cynical ploy by an industry that remains a climate disaster.
Back to the roots, passenger ships, ferries, railways (fast overnight connections).
Ban short-distance flights.
Imagine Ryanair as a fast train operator.
Rail is so nice. I wish there were connections everywhere.
What really should happen is short flights should become electric.
It is no sustainable product, anyway. We did the calculations some time ago, and the results were that in order to supply the airline fuel needed in this country, we would have to turn each and every piece or arable land into rapeseed plantations. Every field, meadow, winyard, whatever. Every year, without any rotation.
Air traffic is unsustainable in general, you can take four people, have them ride a Suburban with a big V8 and they’ll burn less fuel to travel the same distance compared to doing it by plane and that’s not even considering the anti pollution equipment found on road legal vehicles that is pretty much non existent for aircrafts.
