Isn't that kind of a meaningless comparison then? As I said, it is not the kind of pollution one expects when talking about auto pollution. They might as well be claiming that tires produce infinitely more steel belt waste as that is also not something one expects to talk about coming out of the tail pipe. I think focusing on 30 pounds of rubber rather than 18 metric tons of CO2 is a distraction.
