The pollution criteria has been always political issue. You can play with them saying that sot is more poisonous than killer gasses coming from gasoline engine.
Anyway, the subject is always badly misrepresented in US news and I always take them with grain of salt.
General knowledge is that European pollution standards are much more demanding that US standards. Some countries charge registration taxes per pollution that car sellers have to disclosure.
Bottom line, I heard that US hybrids would fail European smog controls and never be allowed to drive there. Maybe a myth, maybe the fact, but with all that propaganda would take quite some research to figure it out.
