Canadian study says ethanol emissions no greener than gasoline
"Looking at tailpipe emissions, from a greenhouse gas perspective, there really isn't much difference between ethanol and gasoline," said Greg Rideout, head of Environment Canada's toxic emissions research.
Basically, the study showed no statistical difference between straight gas and and E10 blend of ethanol and gasoline. There was a reduction in carbon monoxide, but hydrocarbons and other gases increased under certain conditions.
A government environmental official said he was aware of the report but says ethanol use in the big picture is worth the effort.
"I think there's an issue between the tailpipe and the whole cycle," said John Baird, Federal Environment Minister. "The whole cycle is better than the tailpipe."
Testing four vehicles hardly warrants conclusive results but certainly indicates more tests are needed, and we also need to fully test E85 blends, as well.
