Big Oil Behind Yet Another Biofuels Research Paper
When discussing indirect land use it brings a popular saying to mind: If a tree falls in the forest and no one is around to hear it, does it still make a sound? Only in this situation the saying should be modified as follows: If a tree is cut down in a rainforest in Brazil to sell wood, should corn ethanol’s carbon footprint go up? Anyone with an ounce of commonsense would say no.
And here’s why: when a tree is cut down in Brazil, it is not to plant crops for biofuels, it is to sell the wood because the tree is of greater value as wood, then as part of the rainforest. Only then is the land converted to pasture and then to land for crops like soybeans. Sugarcane is rarely grown in the rainforest and Brazil doesn’t produce biofuels from corn. So what I just can’t seem to wrap my head around is what exactly does that tree have to do with corn ethanol?
So what has caused today’s diatribe on indirect land use? A new paper published this month in Bioscience Magazine titled, “Effects of US Maize Ethanol on Global Land Use and Greenhouse Gas Emissions: Estimating Market-mediated Responses.” The paper was authored by Thomas W. Hertel of Purdue University and five co-authors. In a nutshell, the authors argue that the greenhouse gas emission reductions from corn-based ethanol are canceled out when factoring in the increased carbon output from indirect land use change. Therefore, their contribution to California’s Low Carbon Fuel Standard is negligible, even when compared to conventional petroleum based fuels.
There are so many things wrong with this paper that I had a hard time deciding where to begin.

“My administration will reduce the price of food by eliminating the subsidies for ethanol and agricultural goods,” McCain told an invitation-only group at the Harry Truman Library in Independence, Missouri. “These subsidies inflate the price of food, not only for Americans but for people in poverty across the world, and I propose to abolish them.”
