I'm a little confused about something I read in an article in Motor Trend (May 2007). I also heard a reference to this in a news story on the radio as well.
This is with reference to using Gasoline as an automotive fuel and greenhouse gas emissions:
"Hydrocarbons and NOx emissions can be further reduced, but each gallon produces 19.4 pounds of CO2, so improved efficiency is the only CO2 abatement option, and diesel and hybrid technologies are more efficient."
What I don't understand is, if a gallon of gas weighs ~8 pounds, how does burning 1 gallon of gas result in 19.4 pounds of Carbon Dioxide? What are the other inputs (and outputs) of the combustion of gasoline that can result in 19.4 pounds of CO2 resulting from burning only 8 pounds of gasoline?
Please don't get overly technical in your explanation, I don't have a science or engineering background.
Thanks!
