A University of Wisconsin-Madison study finds that greenhouse gases from corn ethanol offset its benefits over gasoline. The researchers attribute this to land-use change, with more corn and less grassland, which the RFS did not anticipate.
The study calls for policy changes.
The findings could prompt scrutiny of RFS volume mandates, which underpin corn ethanol and soybean oil demand, but no immediate policy change is announced.
