Isn’t it ridiculous to state that a gallon of gasoline (6.3 lbs) produces 20 lbs of carbon dioxide?

Visit: http://www.fueleconomy.gov/feg/co2.shtml for an explanation.

It takes oil to make gasoline. In fact, the refining efficiency of one gallon of Gasoline (average) is [I][B]84.5%[/B][/I].

which means it takes [B]0.115[/B] gallons of oil to produce one gallon of refined gasoline.

[I][B]18676[/B][/I] Btu/lbs * [I][B]6.25[/B][/I] lbs/gal = [B]116725[/B] Btu/gal Gasoline

[B]0.155[/B] gal * [B]116725[/B] Btu/gal = [B]18092.38[/B] Btu Oil to produce 1 gal Gasoline

[B]18092.38[/B] Btu/gal / [B]138095[/B] Btu/gal = [B]0.131[/B] gal Oil to produce 1 gal Gasoline

[B]0.131[/B] gal * [I][B]20.2585[/B][/I] lbs CO2 / gal of oil burned = [B]2.6539[/B] lbs CO2 to produce 1 gal Gasoline

=

[B]21.9455[/B] lbs CO2 / gal “Well to Wheels emissions”

That’s [B]21.9455[/B] lbs CO2 emitted from refining and combustion of one gallon of gasoline.
