An EV that's running on a grid that's 100% coal-fired electricity is roughly as clean as the best currently available ICE. The advantage that EV has over the ICE is that its pollutants are centralized at power plants, not being spewed through hundreds of millions of tailpipes in densely populated areas.
It's more efficient to deal with those pollutants at the plants than to try to control it through small catalytic converters which tend to be inefficient when the engine isn't warmed up - but a cold engine is more polluting. There's another boondoggle for you.
Not a big fan of ethanol and wary of using food cropland for growing feedstock for fuel.
