You are making the mistake of thinking that CO2 is the biggest or worst polluter and that only greenhouse pollution matters. Look up sulfur pollution. It is basically non-existent in gasoline, but rampant in other fossil fuels and is far more impactful.

FWIW, often statistics talking about CO2 are actually talking about CO2 equivalent, which is a way of normalising the harm levels of different pollutants. Typically this is used to compare things like farming and fossil fuels, which produce very different gases.

Unfortunately, I can't tell if the source linked actually uses this metric but isn't being clear, or if it's just focused on CO2, and I'm struggling to find another source that does use CO2 equivalent emissions as a metric.

No, CO2 was just the context of the discussion.

I specified I was talking explicitly about sulfur pollution.
