With my figures of simple math, gasoline is producing 338% more CO2 than the weight of gasoline.
No wonder the vegetation is growing like crazy.
Please give me guidance.

Guidance: There are many inaccuracies in your simple math assumptions but the biggest error is that you did not add the weight of Oxygen in the resulting CO2 when gasoline is combusted..

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.

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

I get 50 mpg on my 4 seat Yamaha. A little less when riding 4 people.

Well it all depends if you are "rollin coal" or not
