Argonne slams EWG report on corn ethanol LCA

June 12, 2014 |

In Illinois, researchers led by Argonne National Laboratory and three universities have issued a 13-page response slamming the recent Environmental Work Group lifecycle analysis of corn ethanol, called “Ethanol’s Broken Promise.” The response picks through detail by detail how the EWG report misrepresents, miscalculates or is otherwise completely off the mark.

To quote from the paper’s conclusions, “EWG’s estimated LUC and resulting GHG emissions between 2008 and 2011 appear too high, considering other LUC estimates and data sources and EWG’s use of high LUC emission factors. Furthermore, EWG’s use of EPA’s LUC GHG emissions for base year 2012 seems to be irreconcilable with EPA’s intent and context for reporting 2012 base year emissions. Finally, EWG’s critique of the YDEL value of 0.25 used in GTAP may not be supported by recent analyses.
