How does this whole gasoline - greenhouse gases thing work?

I am seriously confused! I live in "Schwarzeneggarville" and just watched a story on the news in which they were talking about his Hummers and how much greenhouse gases they give off. They said that he uses 415 gallons of gas per year in one of his Hummers and that this results in 8,125 lbs of greenhouse emissions. I believe a liquid gallon of gasoline weighs about the same as a gallon of water, or 8.14 lbs. 8.14 x 415 = 3,378 lbs of gasoline used per year. How does 3,378 lbs of a liquid that is heavier than air become 8,125 lbs of lighter than air gas? This sounds like "fuzzy math". What else, on earth, can one burn and have it more than double in weight?

Update:

Michael: Thanks for the answer. Arnold says that both of his Hummers have been converted. One runs on hydrogen and the other on another environmentally friendly fuel, so the report was more messed up than the first glance would reveal.

    Your math is right, so they obviously misquoted one of the numbers, or you misheard them. Since a hummer gets closer to 10 mpg than 20, and your 8lbs per gallon is close, then if Arny is burning only 415 gal/yr, he's only driving about 4000 miles per year. That's less than half the national avg. But if he drives 12,000 miles per year (like most of us) and he's getting 10 mpg, he's really using 1200 gals. 1200 x 8 = 9600 lbs of fuel, closer to the 8165 lbs quoted. Maybe somebody better proofread the report you heard and do a better job explaining the numbers. Maybe he has 2 or more Hummers and EACH burns about 415 gal/yr.

    Six days certainly, he rested on the seventh. it is not substantial to me no count if he did it in 24hr stages or 1000's of twelve months stages -God is the would extensive-unfold Spirit author. there is regulation and order in each and every little thing God does, numbers have super meanings and importance in Hebrew recognize-how. i think that it became into no twist of fate that the OT became into written in Hebrew which has characters with wonderful subtleties of meanings relating God and non secular realities that English purely can not placed across. yet there is a lot medical information to show that this international is barely approximately 6,000yrs previous quite than billions of years previous -specific good factors ought to not have lasted that long! additionally carbon relationship has been proved to be a shaggy dog tale! - fairly unreliable.
