As a high-level summary the info shows that with the E85 emissions are a bit less than with gasoline, and fuel economy is worse. What cranks me is that I don't see that they take into account the pollution caused by transporting the extra fuel due to the lower MPG, or the added pollution caused by drivers having to stop for fuel more often. If they were honest about it, they'd factor in things like the pollution due to the energy used to pump the additional fuel.
