Here's a free idea:

No refuelling private jets. ✈️

No matter what price they can afford.

Should be an obvious step 0 in a fuel crisis.
But we wouldn't ever do anything to inconvenience the ultra rich, would we?

@pezmico better yet, just tax key fuel for any turbine aircraft holding 12 seats or less. Tax at 200%
@DoctorDNS they can pay those, they stole enough money for it. Zero fuel for them, let them walk/swim to their destinations. @pezmico
