The super rich can easily afford to fly with 100% bio jet fuel thats carbon neutral or even carbon negative.
I flew from KAD last week for some figit hours on my logbook. JETA at the FBO was $6.98 a gallon that’s
$1.88 per liter. With today’s technology you can make jet fuel from thin air for 2 to 3 bucks a liter. The rich would just buy that if CO2 was taxed by the tonne or banned.

Airbus already flew on 100% SAF carbon dioxide aside SAF is much cleaner than Regular jet A it has zero sulfur to form dioxides and it has no benzene or toluene both carcinogens that kill jet mechanics on the regular. My grandfather died of lung cancer from years of exposure to JETA on the B52s he worked with. Grandma still getting paid his benzene levels were lab confirmed via blood and urine. Classed as occupational exposure and full benefits paid plus death benefits and life time funds for the widow. Fossil jet fuel is nasty stuff full of carcinogens.

Amazon is also going to use lower emission fuels. Jets make huge amounts of SOx,NOx,and PM2.5 emissions.

Good information but they say it’s all about the optics.
“With today’s technology you can make jet fuel from thin air for 2 to 3 bucks a liter.”
That really sounds interesting but I’m sure it’s some conjob mumbo jumbo.
