Rationale. In addition to political, economic, and mechanical feasibility, one must consider the environmental consequences of choosing ethanol over gasoline. In par- ticular, the amount of air pollution released in the form of CO2 and other green house gases (GHGs) is a crucial point of interest. In order to model the difference in ethanol and gasoline emissions, it is necessary to calculate the final mass of GHGs (in the case where 10% of the gasoline energy supply has been replaced by ethanol) minus the ini- tial mass (before the 10% replacement was implemented). If the result is negative, the 10% ethanol scenario gives off fewer GHGs; if it is positive, it gives off more. Assumptions and calculations. Our model is based on the following assump- tions: 1.
