As mentioned in section 2.2, the projected gasoline demands (PC) for E10, E20 and E85 vehicles in year 2011 can be broken down into 16.3 ,2.9 and 0.4 ML/day, respectively , in addition to 4.8 ML/ day consumed by motorcycle sthat will run on E10. Thus, passenger cars using gasohol will reduce CO2 emissions by [(16.3ML/day)(0.014 kg CO2e/km)+(2.9ML/day)(0.027kg CO2/km)+(0.4ML/day)(0.101 kgCO2/km)]?(13.5 km/L)¼4.7 kilotonnes CO2/day or 1.7 megatonnes CO2 per year.
