After reassuring myself by looking at wikipedia
http://en.wikipedia.org/wiki/Ethanol_fuel

(the following is directly from wikipedia:

During ethanol fermentation, glucose is decomposed into ethanol and
carbon dioxide.
C6H12O6 -> 2C2H6O + 2CO2
During combustion ethanol reacts with oxygen to produce carbon
dioxide, water, and heat: (other air pollutants are also produced when
ethanol is burned in the atmosphere rather than in pure oxygen)
C2H6O + 3O2 -> 2CO2 + 3H2O
Together, these two equations add up to the following:
C6H12O6 + 6O2 -> 6CO2 + 6H2O + heat

end of quote)

Of course that is the case. But they are both products
that take carbon dioxide out of the air-- ethanol and
vegetable oil. That makes it Carbon neutral. Perhaps
this article will state it better
