50 mpg for Yamaha gas carts manufactured in the last 10 years is about right. Mine is typically a bit over 50 mpg.

Using gas in golf cart uses about 1 gallon in 2.5 hours (2.gal x 20 mpg=50mpg which is typical for gas cart). Round numbers yearly use is 52 gal regular gasoline.
Gasoline is about 6 lbs per gal for regular
a. 13% Hydrogen which produces 0 lbs CO2 when burned
b. 87% Carbon by weight or 5.22 lbs C but adds 10.44 lbs Oxygen
to make CO2. Total CO2 is 15.66 lbs per gal
c Annual CO2 is 52 x 15.6 = 811 lbs per year at 50 mpg
To get to the Princeton numbers, the mileage on the gas cart is more like 27-28 mpg. My 50 mpg is probably too high.
