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 >

Will the Press Set the Record Straight?

Last week, Roll Call revealed that the Grocery Manufacturers Association paid for a PR campaign aimed at blaming high food prices on biofuels (call it the ‘vast chicken wing conspiracy’). But since the revelation, there’s been very little effort in the press to set the record straight. The USDA this week held a press conference to tell reporters the true causes of food price increases. And on Tuesday this week, Michael W. Masters, Managing Member Read More >

Uncontrollable Forces

Two editorials in the New York Times this week have claimed that rising oil prices are “uncontrollable forces” and “not anyone’s fault.” (See The World Food Crisis, 4/10/08 and Grains Gone Wild, Paul Krugman, 4/7/08). The implication is that biofuel policy in the United States IS controllable – and eliminating use of food crops for biofuels will allow U.S. grains to fill markets throughout the world. This scenario ignores the effect that oil prices have Read More >

Trying to Define the Indirect Land Use Issue

Michigan State University Professor of Chemical Engineering Bruce Dale recently sent a letter to colleagues interpreting the analyses by Searchinger et al. and Fargione et al. in Science. In the letter, Dale says, “The Searchinger and Fargione argument at its root is this: corn (and perhaps cellulosic) ethanol is not sustainable because it will divert land use for animal feed (over 70% of corn is fed to animals) to new lands that will release large Read More >
