As for typical tailpipe measured emissions, E85 is % better for the environment. Even 10% ethanol (or gasahol) fuels are a % better.
E85 or E100 (pure ethanol) has more O2 present in the fuel and has significantly less CO emissions that pure gasoline or 10% ethanol gasoline.
E85 or E100 has a the same or slightly higher HC emissions than pure gasoline.
Typically NOx emissions are on par with gasoline fueled vehicles.
As for non typical measured tailpipe emissions, I have not seen conclusive data on other emissions emitted from the tailpipe.
