Compounded Climate Accounting Errors

Timothy Searchinger, visiting scholar at Princeton University, Dan Kammen of the University of California Berkeley, David Tilman of the University of Minnesota and other authors from the Environmental Defense Fund published an interesting new proposal in the Policy Forum section of Science magazine today. The argument put forward is that “Replacing fossil fuels with bioenergy does not by itself reduce carbon emissions, because the CO2 released by tailpipes and smokestacks is roughly the same per Read More >

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?

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 >

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 >
