In this study, a substantially broader set of eight environmental impacts is covered. An LCA of corn-stover ethanol production for Ontario (Spatari et al. 2005) is available, but did not consider changes in soil carbon stocks resulting from stover removal, and there are no similar studies examin- ing the impact of corn stover collection for EtOH in Quebec. The carbon intensity (CI) of corn ethanol—i.e., the greenhouse gas emissions produced via the production of a volume of the fuel—is declining, while the average CI of gasoline produced from petroleum sources is gradually increasing, according to a recent report prepared by Life Cycle Associates, LLC for the Renewable Fuels Association (RFA).

North Dakota-based Red Trail Energy (RTE), which since 2007 has operated an ethanol production facility with annual production of about 60 million gallons per year, is proposing sequestration of CO 2 produced from starch fermentation to lower the overall carbon intensity of the fuel for the California Low Carbon Fuel Standard (LCFS).

This represents just a 20 to 45% positive energy balance when producing ethanol from corn. This number has been the criticism of corn ethanol because of the large amount of fossil energy used to produce ethanol.

Lifecycle assessment(LCA) is a technique which is becoming in- creasingly there is a net increase in GHG emissions from using corn ethanol compared.
The RIN credit a biofuel receives is based on the combination of feedstock, fuel and process that produce it. We applied both LCA and SWA to assess the GHG impacts of ethanol based on Iowa corn. Growing corn in rotation with soybeans generated 35% less GHG emissions than growing corn after corn. Based on average corn production, ethanol's GHG benefits were lower in 2007 than in 2006 because of an increase in continuous corn in 2007. Cellulosic ethanol should earn producers carbon reduction credits, higher than those given to producers who grow corn for ethanol, which is about 3 to 20 cents per gallon. It takes 0.76 J of energy from fossil fuels to produce 1 J worth of ethanol from corn. 2013-11-13 · Ethanol fuel plant in West Burlington, Iowa.
