ethanol still will procuce C02 as a biproduct

Not my field of science, but would ethanol produce even more CO2 per mile than gasoline does? Seems like ethanol is intended for the US to get free of terrorist-produced oil rather than qualities like efficiency or cost.

I was watching a feature on the Discovery Channel called The Cars of The Future, that ethanol produces zero CO2.
