EPA Denies Texas Request to Waive RFS

Today, EPA Administrator Stephen Johnson announced the decision to deny Texas Gov. Rick Perry’s request for a waiver of the Renewable Fuel Standard. Johnson said in a press release: “After reviewing the facts, it was clear this request did not meet the criteria in the law. The RFS remains an important tool in our ongoing efforts to reduce America’s greenhouse gas emissions and lessen our dependence on foreign oil, in aggressive yet practical ways.” In Read More >

A Tale of Two Studies

Don Mitchell of the World Bank’s Development Prospects Group has released an official version of his analysis of biofuels’ impact on the rise in global food prices. An early version of the study was leaked to the Guardian in London on July 4. Mitchell attributes 70 to 75 percent of the increase in food commodities prices to “biofuels and the related consequences of low grain stocks, large land use shifts, speculative activity and export bans.” Read More >

Purdue University Weighs In on What’s Driving Food Prices

The Farm Foundation recently released a report prepared by Purdue University agricultural economists on the forces driving food price increases. They conclude that higher food prices are the result of the complex interaction of global changes in supply and demand for commodities, the depreciation of the U.S. dollar, as well as growth in production of biofuels. According to the authors, these factors have combined to rapidly raise demand for U.S. grains beyond current production, leading 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 >
