Visualizing the indirect effects of oil

It has been pointed out numerous times on this blog (here, here and here) that you can’t have a true comparison of fuels if you account for the direct effects of all fuels and the indirect effects of only one. But that is what the U.S. Environmental Protection Agency (EPA) and the California Air Resource Board (ARB) have proposed. Both the EPA in their proposed RFS II rules and ARB in their Low-Carbon-Fuel-Standard have calculated the Read More >

Corn Growers Try to Understand Indirect Land Use Change

The National Corn Growers Association’s recent “Land Use: Carbon Impacts of Corn Based Ethanol 2009” conference highlighted the confusion the issue of indirect land use change has engendered for farmers. Chuck Zimmerman of AgWired summed it up in a report from the conference: Do you understand things like indirect land use when it comes to regulations via departments like the EPA due to the RFS? Me either. And I’ve sat in on conferences and discussions Read More >

Piping in the Tar Sands

Previously on this blog, I posed this question: Ethanol or Tar Sands? With Canada as the largest supplier of petroleum to America, it was a simple question: do we want to get the additional transportation fuel we need from domestic, renewable sources or from clearing Canadian forests? Well, we got an answer of sorts late last week when the U.S. State Department issued a permit to Enbridge Energy Corp. to build a 326-mile pipeline from Read More >

Why ILUC Theory Bears No Resemblance to Reality

Iowa State’s Bruce Babcock has written a defense of the current economic equilibrium models used by the EPA and California Air Resources Board, in light of the fact that the models’ assumptions about soybean production and acreage have turned out wrong. Babcock frames the debate over international land use change as “whether the models used by CARB and EPA are accurate enough to support regulations.” There is, however, a larger question over whether the models are Read More >

Strange Bedfellows Indeed

The Environmental Working Group, Friends of the Earth, the Grocery Manufacturers Association, the National Marine Manufacturers Association, the National Petrochemical & Refiners Association, and the Natural Resources Defense Council have cosigned a series of letters to Senate leaders opposing additional study of the theory of indirect land use change. These groups would like to lock in the EPA’s current measurement of indirect land use change, which includes heavy penalties for corn- and soybean-based biofuels. The Read More >
