Better Than Predicted: The Digest’s 2019 Multi-Slide Guide to USDA’s Corn Ethanol GHG : Biofuels Digest


It’s all about the life cycle, right? That’s what the USDA set out to find out about corn ethanol – just exactly what are the GHG emissions associated with the production of corn-based ethanol in the U.S.? Back in 2010, the RIA LCA concluded that – on an energy equivalent basis – substituting corn ethanol for gasoline in transportation fuels would result in a reduction in CO2 emissions of 21 percent by 2022. But what’s happened since 2010? Well, a lot of things…

Jan Lewandrowski, Senior Economist at the USDA, Office of the Chief Economist, gave this illuminating overview of what’s changed since 2010 that makes new studies even more interesting, like why global iLUC (indirect land use change) was much less than projected, how new data and industry trends support lower GHG profile for corn ethanol, and more at ABLC 2019 in Washington, D.C.
