I don't think it's pollution they're looking at here: it's cost. E.g. the cost to go the equivalent distance as the cost of a gallon for an otherwise equivalent car. Perhaps I'm wrong. But bringing emissions in adds significant value to the electric option: value not yet realized since externalities like CO2 emissions are not currently paid for.
