According to the US Energy Information Administration Website:
"About 19.64 pounds of carbon dioxide (CO2) are produced from burning a gallon of gasoline that does not contain ethanol. About 22.38 pounds of CO2 are produced from burning a gallon of diesel fuel."
High school chemistry was not my strong suit so how does (about) 6 pounds of fuel produce some 20 pounds of emissions?
diesel has a higher carbon content, hence more CO2 per gallon, but also higher energy content per gallon. pretty much balances out once mpg is taken into account.
