EPA Continues to Move Toward Calculation of Indirect GHGs
Dr. Bruce Dale of Michigan State University published a Commentary in the Washington Times on Nov. 26, calling for sound science in development of the EPA’s rule on the Renewable Fuel Standard. Dr. Dale points out, “No actual data exist that connect U.S. domestic ethanol production with, to cite a widely quoted example, the clearing of the Amazon rain forest. Instead, the paper’s conclusions depend entirely on economic modeling and assumptions.” He then discusses his Read More >

Senators Weigh In on EPA Rules
On Monday Nov. 17, six U.S. Senators sent a new letter to EPA Administrator Stephen Johnson echoing a proposal that BIO previously made. BIO earlier called on EPA to release its proposed methodology for measuring greenhouse gas emissions during the rule’s comment period, but withholding conclusions on specific levels of reductions achieved by particular biofuels until the methodology was complete. The Senators’ letter states: The methodology ultimately used by EPA in crafting this program will Read More >

Life Cycle Analysis, International Land Use Change and Uncertainty
Bruce Dale, University Distinguished Professor of Chemical Engineering at Michigan State University, shared this presentation that he gave during a webinar hosted by the North Central Bioeconomy Consortium. In it, he highlights the number of factors in Life Cycle Analysis and Indirect Land Use Change (ILUC) models that produce uncertainty – in other words, if the assumptions or data for these factors change, how much do the results change. Dale is primarily examining the “carbon Read More >
More Models to Measure Land Use Change
As the U.S. EPA and California’s Air Resource Board seek to implement their respective Renewable and Low-Carbon Fuel Standards, economists continue to refine models to measure and predict indirect land use change emissions associated with biofuels. Many of the original critiques of the Searchinger paper in Science that initiated this debate commented on the uncertainty in attributing indirect land use change to biofuels. Prof. Roger Sylvester-Bradley of ADAS UK Ltd., for instance, summarizes many of Read More >
