Impact of Missouri's E10 Standard on Consumer Fuel Usage, Public Health, & the Environment*

Abstract

On January 1, 2008, the Missouri Renewable Fuel Standard Act (RFSA) became effective; mandating that all gasoline sold in the state contain 10% ethanol. The fuel with 90% gas and 10% ethanol is commonly referred to as “E10.” Proponents of the law claim that “Missouri's [RFSA] benefits consumers, our economy, the environment, and Missouri farmers.” Others celebrate the new standard for reducing Missouri's dependence on foreign oil, developing a new production industry, and providing greater demand for locally grown crops. Some consumers however believe that E10 noticeably decreases their fuel-economy. In a Columbia newspaper article, one man said, “I think it's idiotic, my car runs worse with it. I don't like [E10]. It's not nearly as good.” Regardless of one's viewpoint, it is important to evaluate Missouri RFSA's impacts on consumers, the environment and the economy.
