MINNEAPOLIS -- A new University of Minnesota study finds that corn ethanol is no better than gasoline when it comes to fuel -- and may be worse for air quality.

The study estimates the economic costs to human health and well-being from gasoline, corn-based ethanol and plant-based ethanol.

Researchers concluded that ethanol made from switchgrass and other plant materials is far better than either corn ethanol or gasoline. The study examined life-cycle emissions of growing, harvesting, producing and burning different fuels.

State estimates say ethanol is a $6 billion industry in Minnesota.

Ethanol advocates say they haven't seen the study and will need time to understand how its conclusions were reached.

The university's study will be published in this week's issue of the Proceedings of the National Academy of Sciences.
