A critique of soil carbon assumptions used in ILUC modeling

Recent estimates of land use change emissions vary widely, in part due to differences in assumptions on soil carbon. In this report, we review a recent meta-analysis on soil carbon changes with land...

Is the Renewable Fuel Standard inadvertently driving up U.S. palm oil imports?

If you’re reading this on your lunch break, take a look at the ingredients label on your cookies. Chances are you’ll see one or a combination of soybean oil, palm oil, and canola oil, perhaps...About a third of all U.S. soybean oil goes into biodiesel that the RFS requires to be blended into diesel fuel. That's soybean oil that's no longer available to use in food products, leading to...
