EPA Finalizes Biofuel Rules; Corn-based & Cellulosic Ethanol reduce Greenhouse Gas Emissions

corn based ethanol


The Obama Administration announced this week new biofuel rules for a Renewable Fuels Standard (RFS2). The EPA will calculate greenhouse gas emissions from biofuels in the following way:

- Corn-based ethanol with international indirect land use included: 21 percent reduction.
- Corn-based ethanol without that land use included: 52 percent.
- Cellulosic ethanol: between 72 and 130 percent reduction, depending upon feedstock and conversion process.

According to the EPA rules, by 2012, "at least 7.5 billion gallons of renewable fuel must be blended into motor-vehicle fuel sold in America."
