Abstract
this article, we highlight our findings regarding energy, economic, global climate change, air quality, and soil health impacts. The System Boundaries Stakeholders established the system shown in figure 1. The stages of the life cycle for bioethanol include (1) production and collection of stover on the farm, (2) transport of the stover from the farm to a processing facility that produces ethanol and electricity, (3) distribution of ethanol to retail fueling stations, and (4) use of the ethanol in the form of E85 (85% ethanol/ 15% gasoline on a volume basis) in a flexiblefuel light-duty passenger car. Because we want to understand the impact of switching from gasoline to ethanol, we also include all of the life-cycle stages for gasoline, from extraction of crude oil in the ground (both domestically and around the world) to the use of gasoline in the same flexiblefuel vehicle (FFV) that can operate on any fuel mixture containing 0 to 85% ethanol in gasoline. The total life-cycle flows from gasoline use in this system are treated as avoided flows, meaning that the life-cycle flows associated with driving 1 kilometer (km) on gasoline are subtracted from the life-cycle flows associated with driving 1 km on E85. At the same time, a portion of the life-cycle flows for gasoline production are added to the ethanol life-cycle system to account for the 15% volume per volume (v/v) gasoline content of E85
