Ethanol Receives Lower Land Use Change GHG Emissions Rating

Agronne National Laboratory (ANL) recently published a manual for the Carbon Calculator for Land Use Change from Biofuels Production (CCLUB), lowering the value to 7.6 gCO2e/MJ, down 9.0 from last year’s modeling, and four-times lower than the 28 gCO2e/MJ used by the Environmental Protection Agency (EPA) in determining greenhouse gas (GHG) reduction relative to gasoline under the federal Renewable Fuel Standard (RFS).
