The problem with saving fuel..
is that it can never end, by definition.
It's like the "war on drugs" or the "war on terrorism" or the "war in the ME": it must always be fought, and attacked, and new strategies must be formulated by newly-formed committees. It must be perpetual.
For example, we could all (probably safely) reduce our uplift tomorrow by 100kg on each and every sector. Will that bring happiness, laughter, celebrations and bonuses?
No, it will bring forth another plea to please save another 100kg the day after...
And so on and so forth.
Don't get me wrong; I have no problem with running a safe and fuel-efficient business, like we have been doing for the last 70 years. By the way, how's our yield management going?
