A new peer-reviewed study of transportation fueling options generated a pretty good buzz last week, basically for the finding that electric vehicles might not be as good for the environment as previously thought. Another of the study’s conclusions also is worth underscoring: the negative environmental impacts of corn ethanol in fuels.

A team of University of Minnesota researchers assessed life-cycle air quality impacts of 10 alternatives to conventional gasoline vehicles. On corn ethanol:

We find that powering vehicles with corn ethanol or with coal-based or “grid average” electricity increases monetized environmental health impacts by 80% or more relative to using conventional gasoline.

Sometimes the public policy debate occurs at an academic level, and it’s easy to overlook the impact on real Americans.  A good example is the campaign to push higher ethanol-blend fuels into the marketplace, which could negatively affect millions of consumers and hinder the broader economy. True enough, but we should also look at the real-world impacts of forcing increasing levels of ethanol into the fuel supply, impacts on individual Americans like Russell Garcia in Chicago.

Garcia owns five independent service stations in Chicago. He recently wrote a letter to the editor of the Chicago Tribune to point out the consequences of a city council proposal to require Chicago gas stations to carry E15 gasoline – fuel containing up to 15 percent ethanol, 50 percent more ethanol than the E10 gasoline that’s prevalent across the country.

Garcia wrote that E15 won’t deliver benefits promised by proponents, such as cost savings and environmental improvements. Instead, he wrote, it would impact consumers and small business owners like himself and ultimately be worse for the environment.
