Study finds that environmental impact of corn-ethanol E85 is 23% to 33% higher than that of gasoline; environmental problem-shifting

Green Car Congress

Environmental impacts of gasoline and E85. The singular emphasis on energy balance and the carbon footprint neglects numerous other impacts associated with biofuels production including those related to irrigation, fertilizer application, and pesticide use for feedstock growth. Process flow diagrams for E85 and gasoline.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Researchers from the University of Minnesota have produced a spatially and temporally explicit life cycle inventory (LCI) of air pollutants from gasoline, ethanol derived from corn grain, and ethanol from corn stover for the contiguous US (the lower 48 states). Dashed lines show US average emissions. Credit: ACS, Tessum et al.

Harmonizing Low Carbon Fuel Standards

Green Car Congress

—Low Carbon Fuel Standard 2011 Program Review Report. The California LCFS regulation, which went in to effect on 15 April 2010, targets a reduction of the carbon intensity (CI), on a full-fuel lifecycle basis, of transportation fuels (measured in gCO 2 e/MJ) used in California by an average of 10% by the year 2020.

ARB posts 5 new LCFS pathways; two renewable diesel

Green Car Congress

California Air Resources Board (ARB) staff has posted five new and one revised Low Carbon Fuel Standard (LCFS) fuel pathway applications to the LCFS public comment website. The revised package is for corn oil biodiesel. DGD’s proposed carbon intensities (CI) for the two new pathways are 21.10 Charles, Louisiana in June 2013.

NSF Awards $40M in 20 Grants for Research on Natural Systems, Including 8 Projects for Obtaining Hydrocarbons from Plants and Microorganisms

Green Car Congress

The project “Maximizing Conversion of Biomass Carbon to Liquid Fuel” (0938033) will be led by Rakesh Agrawal, with colleagues Mahdi Abu-Omar, Nicholas C. This organism has the potential to directly produce petroleum using a cellulose fermentation process that is essentially carbon neutral. Carpita, Maureen C. McCann, and Fabio H.
