How much carbon dioxide does one car produce a month?
Answer 1:
I would average it to be 1200 lbs of carbon dioxide a month. there are many yearly averages out there on the net so after looking at many of them I just estimated.

Answer 2:
A typical vehicle averages 15,000 miles per year, at about 20 miles per gallon (in the US). Each gallon of fuel burned emits 14 lbs of CO2. So dividing 15,000 by 12 (to get the monthly number of miles driven) we obtain 1250 miles. Dividing this by 20 gives us the number of gallons consumed per month: 63. 63 gallons times 14 lbs per gallon yields about 875 pounds of CO2 per automobile per month.
