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 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 >
Does Oil Cause Indirect Land Use Change?
I’ve been paying a lot of attention recently to new analyses attempting to model carbon emissions from indirect land use change, which is the conversion of land needed to maintain an international balance of supply and demand for agricultural crops, an effect that is heavily determined by crop prices. These new analyses raise a question about the existing assumption that oil has zero effect on land use change. Tim Searchinger, the lead author of one 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 >
