Sorry, I'm apparently unable to post links here What I tried to post for the calculation of 20 pounds of CO2 for every gallon of gas (and which the Independent removed) comes from:

On Elizabeth Kolbert on the End of the World

I think Elizabeth Kolbert's stated lack of a science education is showing here. She says: "I mean, there are 20 tons of CO₂ for every gallon of gas you combust in your car. It is difficult for even me to wrap my mind around. It is not necessarily something you would have expected to happen, but it turns out that this is just the way that the world works."

The reason she has such a difficult time wrapping her mind around these numbers is that 20 tons of CO₂ for every gallon of gas is off by a factor of 2,000. The correct number is 20 *pounds* of CO₂ for every gallon of gas, not 20 tons. The number is easily derived from the relative atomic weights of carbon and oxygen. For the correct calculation see: <http://www.fueleconomy.gov/feg/conten...>
