Except CO2, which tracks closely with MPG

CO2 is not a pollutant.

Wow sir very sad ,, this is why I alway’s show my support for our President by leaving the Buick running while it is in the Garage

Yes sir. And while Electric Cars are hyped today, much of electricity is still produced by coal based power plants in many countries. Hence gas run cars may be cleaner than e-cars.

Yep, and there are 1 billion of them currently on the road now around the world compared to ~200 million in 1960. And this does not include trucks, buses, and other gas powered transport. I cannot believe you are considered a leading intellectual of the Far Right.

By that calculation, in total that means 5% compared to 1960's reference 100% except if the old vehicles are still on the road. Regardless, you must address the tremendous utility that cars provide. Finally, please include the numbers for the other vehicles since you bring it up.

The whole argument is kind of ridiculous. There ARE a lot of old vehicles still on the road that have poor mpg - Stefan’s using his statement to suggest that the entire current fleet emits 99% less pollution. Second, he refers to “pollution” generally - not specifying CO2, vs NO2

or other pollutants. Cars have improved massively on many other pollutants, but CO2 emissions are only targeted by mpg improvements. A better statistic to look at, above all, is the rise in CO2 emissions from the transportation sector overall, which is getting worse not better,

due to the continued growth in gas vehicle usage, without commensurate improvement in efficiency. But the fact is, to avoid the worst climate predictions we have to improve mpg, phase out most gas vehicles, and improve transportation efficiency generally.
