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 >

EPA Gets Input on Sustainable Biofuels

On Monday Oct. 27, the EPA’s Science Advisory Board held a workshop in Washington on “Looking to the Future.” The stated purpose of the workshop was “to stimulate SAB thinking about priorities for meeting critical environmental problems with an integrated approach to interdisciplinary science and research” and gather data on the net environmental implications of biofuels. A number of experts on biofuels and agriculture gave SAB presentations on land use change and other possible climate Read More >

EPA Drafting Rules on International Land Use Change

The U.S. EPA is expected to release a proposed rulemaking for implementing the lifecycle analysis requirements for biofuels under the renewable fuels standard. (Check out the EPA’s official blog, even though it contains no posts on this subject.) Estimating the emissions generated through the production of biofuels has been controversial, particularly with respect to how land-use changes affect emissions. E&E TV’s OnPoint recently interviewed Jack Huttner, vice president of Dupont Danisco Cellulosic Ethanol, about the Read More >

What Do You Know, Oil Does Cause Land Use Change

In a recent post, I questioned the apparent assumption in the current debate over greenhouse gas emissions from biofuels that petroleum gasoline production does not have an effect on land use change. It turns out there is a well-developed literature on the direct land use change effects of oil exploration in the Amazon and South America. Chris W. Baynard of the University of North Florida Department of Geology presented a study, “Venezuela’s Heavy Oil Belt: 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 >
