I think the best way is to tax fuel itself. This way worse mpg result in more tax.
Tax diesel more than gasoline, LNG less.

Thereby penalising existing vehicle owners who can’t switch to a more efficient vehicle overnight.
We have to come up with a rigorous alternative that doesn’t disproportionately affect lower income folk, because people tend not to be overly concerned about nebulous concepts like the climate impacts on unborn future generations, especially when my carbon impact at the margin is negligible when taken in context of global population.
That makes sense, but there would be no incentive to switch to an engine that emits less carbon for the same fuel consumption (if such a thing exists)
Incomplete combustion is a big component of emissions, and it's exactly what you're saying doesn't exist
Yes but since incomplete combustion is inverse correlated with fuel efficiency (unburned fuel is wasted fuel), it's not really a trade off. What is a trade off is NO emissions vs fuel efficiency. Burning your fuel oxygen rich will burn of more fuel, but also makes more NO (due to higher temperatures if I remember correctly).
By definition, more carbon is less efficiency. Efficiency is about how much of the hydrocarbon you turn into heat. Diesels often burn a little dirty. That's partly because diesel engines don't burn all the fuel
We already do in the US (but the money mostly goes to road maintenance)
Isn't that what a carbon tax is? Adding a tax to the fossil fuel based on carbon content.
This is already done, in Europe most of the fuel costs are taxes.
