Ethanol production in the United States has been steadily growing and is expected to continue growing. Many politicians see increased ethanol use as a way to promote environmental goals, such as reducing greenhouse gas emissions, and energy security goals. This paper provides the first thorough benefit-cost analysis of increasing ethanol use beyond four billion gallons a year, and finds that the costs of increased production are likely to exceed the benefits by about three billion dollars annually. It also suggests that earlier attempts aimed at promoting ethanol would have likely failed a benefit-cost test, and that Congress should consider repealing the ethanol tariff and tax credit.
