the carbon dioxide doesn’t come from just the the gasoline, but rather the gas and the oxygen the car uses. A car combusts gas and oxygen and ends up with CO2. The carbon (C) comes from the combustion of gas, and the oxygen (O2) comes from the air. Also, a car uses many more pounds of oxygen than gas, so thats where it comes from.

Don’t forget the gas wasted in lawn equipment. The EPA estimates that 5 to 10% of all air pollution comes directly from lawn equipment. Switch to push mowers or electric mowers. We use electric equipment powered through renewable energy in our lawn care business & it works just fine!

Hey, I was wondering if you could do me a favor and try writing those first couple of sentences over. I have no idea what you’re trying to say.

Also, if you could point out where the article is incorrect, I’d appreciate it.

Wow, awesome. Yes. The oil shortage only has to do with gas prices at the pump totally not ignorant of the entire situation at all…

No one even blink an eye about BOTTLED WATER, or the PLASTIC BAGS walmart hands out. Huge petrolium based products.

Switching your gas use wont change shit, killing petroleum use outside of fuel will make a bigger change than anything.

Correct the article, do some research.

I don’t know about the rest of you, but I’m mainly trying to drive less. It takes a lot more planning during the week, but if I can just go to the grocery store once rather than 3 times, that will help a ton right there!

Mark, the key here is that it is 20 pounds of carbon dioxide, NOT 20 pounds of carbon. In that 20 pounds, there are about 14.5 pounds of oxygen that combined with about 5.5 pounds of carbon from the gasoline in the cylinders. The remaining 0.8 pounds from the 6.3 pounds of gasoline in the gallon is hydrogen.

This analysis is from a very over-simplified picture of gasoline chemistry, analyzing it as pure normal heptane, C7H16. Real gasoline is, of course, spectacularly more chemically complex. Nevertheless, the central concept is accurate.

Mathew, that’s an interesting web site, I’ve been there before. While I was impressed with what the author had done, and it gave me ideas, there were a few mistakes. One example is the formula for engine mass airflow. All of that aside, each point he makes is valid and accurate.

For Mark, the key is that it’s not 20 pounds of carbon, it’s 20 pounds of carbon dioxide. In that 20 pounds, 14.5 pounds is oxygen from the atmosphere that combines in the cylinder with the 5.5 pounds of carbon from the gasoline. The remaining 0.8 pounds of “stuff” in the gasoline is hydrogen.

Mark – trust me, that’s not a stupid question; I wondered the exact same thing. Check out the below link from FuelEconomy.gov for the answer:
