Environmental impacts of gasoline and E85. In a similar way, the full breadth of impacts attributable to conventional gasoline production, such as natural resource consumption and hazardous pollutant emissions, must also be considered in order to make balanced comparisons to biofuels.

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). The researchers included a sixth pollutant, ammonia (NH 3 ).

Researchers say fuel market rebound effect can result in increased GHG emissions under RFS2; suggest taxes over mandates

Green Car Congress

However, argues a team from the University of Minnesota in an open-access paper published in the journal Energy Policy , once the “fuel market rebound effect” is factored in, RFS2 actually increases GHG emissions when all fuel GHG intensity targets specified under the act are met. for its analysis. —Hill et al.
