Nowhere in that article does it state or even hint that ICE vehicles pollute less or are more efficient than EV's or even PHEV's. If I missed something, feel free to link directly to the line/paragraph, by selecting the text and clicking "Copy link to highlight": Example:

In most locations, BEVs save 40%–60% of emissions compared to ICEVs, though these values can vary substantially at the extremes (0–4700 kgCO2eq yr−1 or 0%–82%).
