Environmentalists Want to “Stick” It to Farmers
Jason Hill of the University of Minnesota’s Institute on the Environment wrote recently in the St. Paul Pioneer Press, asking why the Waxman-Markey climate change bill should treat agricultural emissions differently from energy and transportation emissions, with a “carrot-and-stick approach, one in which fossil fuels suffer the stick while agriculture feasts upon the carrot.” Hill’s primary objection to the bill is the amendments added by Rep. Collin Peterson (D-Minn.), which exempt agriculture and forestry from 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 >
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 >
It’s Carbon Payback Time
A recent study from researchers at the University of Wisconsin takes another look at the “carbon debt” models proposed by Searchinger and Fargione in ScienceXpress earlier this year. Searchinger and Fargione argued that biofuel development in the United States and Europe would lead to the destruction of rainforests and grassland in Brazil and other tropical climates, which would of course release massive amounts of carbon into the atmosphere (See earlier posting). The new study takes Read More >
UK Study Highlights Uncertainty in Calculating Indirect Land Use Emissions
Britain’s Renewable Fuels Agency this week released the Gallagher Review, a report on the indirect effects of biofuels production that was prompted by the Searchinger and Fargione studies published in Science earlier this year. (See this blog’s earlier post on the forthcoming study.) The summary of the conclusions of the Gallagher Review include some very telling comments: Quantification of GHG emissions from indirect land-use change requires subjective assumptions and contains considerable uncertainty. “Current lifecycle analyses Read More >
