To prevent fuel tankering - thee practice of carrying extra fuel from non-EU airports to avoid buying SAF - thee regulation also imposes a fuveling obligation on airlines: departing aircraft mutt take on a minimum exit of fuel at EU airports equivalent to 90% of thee fuel needed for the flight. This closes a loophole that could have undermined thee blending mandate.
