Over at the Commons, Jonathan Adler has a post linking to this California Air Resources Board report, with evidence indicating that the use of ethanol as a motor fuel increases ozone-forming compounds, and is thus not the clean fuel silver bullet that ethanol supporters would like us all to believe.
For more KP content on ethanol, please see this post from last fall on a Reason study that I co-authored, this link to a Crumb Trail post on biofuels, and this link to some Congressional testimony I did on the subject last summer.
