Last month, we announced that analysis by Dr Stephen Mueller, principal research economist at the University of Illinois in Chicago, concluded that if all gasoline was converted to E15 from E10 in Minnesota would eliminate 358,000 metric tons of CO2 equivalent (CO2e) a year.  CO2e includes carbon dioxide, nitrous oxide and methane.

Using the U.S. Environmental Protection Agency’s (EPA) greenhouse gas equivalencies calculator, this would amount to eliminating 75,368 passenger vehicles from Minnesota’s roads annually.

Today, Fuels America announced that if E15 became the new regular in Iowa, there would be a reduction of 220,821 metric tons of CO2e annually in the state. This, it said, is the equivalent to removing 46,489 cars a year from Iowa's roads for a year.

Earlier this month, it also said that if half of the fuel consumed in Wisconsin is E15, the state would be able to cut 175,636 metric tons of CO2e a year which is the same as removing 36,976 cars for a year from Wisconsin's roads.
