On January 12, 2017, USDA released a report on the lifecycle greenhouse gas (GHG) balance of corn ethanol, titled “A Life-Cycle Analysis of the Greenhouse Gas Emissions of Corn-Based Ethanol.” The study reviewed industry and farm sector performance over the past decade and found that in the United States corn-based ethanol generates 43 percent less GHG emissions than gasoline. Compared to previous studies, the lifecycle GHG benefits were greater due to improvements in corn production efficiency, conservation practices, and ethanol production technologies. The report also presented two projected GHG emissions profiles for corn ethanol in 2022, with one assuming a continuation of observable trends and the other analyzing additional improvements that could further reduce the GHG emissions.
