The study in the Journal of Industrial Ecology by Liska et al. referenced in both this article and several postings (e.g., Aureon Kwolek) is one in a **series** of articles on corn ethanol (see The series starts with the aforementioned article by Liska and colleagues (2009) that presents the Biofuel Energy Systems Simulator (BESS). BESS is a model developed at the University of Nebraska as a more updated alternative than the widely used GREET (Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation) model developed by the U.S. Argonne National Laboratory. Using BESS, Liska and colleagues estimate around 50% lower GHGs than gasoline for corn-ethanol—a twofold larger reduction than reported in some previous studies. Plevin (2009a) critically compares the BESS and GREET models, exploring where differences arise and proposing improvements to both and estimating a much less dramatic improvement of corn-ethanol's greenhouse gas impacts than Liska and colleagues. A rejoinder from Liska and Cassman (2009a) accepts some of the modifications suggested by Plevin (2009a) while simultaneously raising several new issues that further reduce the estimate of GHGs attributable to corn-ethanol relative to gasoline. The scientific debate is put in context by a fourth article, an editorial by Anex and Lifset (2009a). Plevin (2009b) takes issue with the response from Liska and Cassman in a letter to the editor which, not surprisingly, prompts a letter back (Liska and Cassman 2009b). The editors (Anex and Lifset 2009b) once again summarize and contextualize the debate in a postscript. Because of the timeliness of this topic—and the high quality of the analyses—the articles are being made available for free download.
