Environmental Groups Pressure EPA to Calculate Indirect Emissions
The latest salvos on the EPA’s rulemaking process for the Renewable Fuel Standard come from six major environmental groups – the Environmental Defense Fund, National Wildlife Federation, Natural Resources Defense Council, Friends of the Earth, Union of Concerned Scientists, and Environmental Working Group – and academics at the University of California Berkeley. In their letter to EPA Administrator Stephen Johnson, the environmental groups argue that delaying conclusions about which biofuels make the grade under 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 >
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 >

How to Measure Land Use Change
Both the U.S. EPA and California’s Air Resources Board are currently considering how and whether to incorporate the indirect effects of U.S. biofuels production on carbon emissions from land use change in other parts of the world. The Renewable Fuel Standard passed by Congress in December 2007 requires inclusion of “significant emissions from land use changes” as part of the life cycle analysis of carbon emissions from biofuels. The Low Carbon Fuel Standard adopted by Read More >
