Where did you get the "over a million gallons of kerosene" figure? The figure I found [1] is 260,760 lbs in the first stage, which works out to almost exactly 25,000 US gallons in the first stage, which uses the large majority of the propellant. The Wikipedia article [2] says 38,570 US gallons of RP-1 in the first stage and 4,500 US gallons in the second.

I thought I heard that in their stream. Must have been a million lbs of fuel+oxygen and not a million gallons of fuel. Sounds like close to ~125,000lbs of CO2 emissions per passenger then. With Starship being methane based (higher H to C ratio) and at bigger scale hopefully it gets that number down a lot. This lists it at 1.1 million lbs fuel+oxygen and shows it being used with Dragon (did they use this or similar?): https://en.wikipedia.org/wiki/Falcon_9_Full_Thrust#Block_3 https://en.wikipedia.org/wiki/Falcon_9_Full_Thrust#Block_3

  From the stream: "Prior to liftoff, the Falcon 9 first stage is loaded up with nearly one million pounds of fuel and liquid oxygen." - https://youtu.be/3pv01sSq44w?t=1920 https://youtu.be/3pv01sSq44w?t=1920
