24 percent of diesel vehicles, it has been corrected.

Edit, 24% of VW's US sales were clean diesels.

If you have to call a energy source, "clean", it's because it's not. A "clean" energy source is one where a lot of technology has been created to try to limit the damage use of that source causes.

Assorted disclaimers:
there is no impactless energy source, politics stinks, cars are a necessary evil, if someone told me that was wrong I wouldn't have done it

98 jetta tdi puts out 4.9 tons of greenhoues gas per year while the 04 civic puts out 5.3 for example in typical drive scenarios.

Clean diesel is to aid the perception of dirty diesel i.e. old diesel cars. A large part of the black smoke has to do with the ultra high sulphur content of US diesel fuel (laughable compared to other countries) and older technology predating direct injection/precision digital timing. (Injecting late in the stroke massively increases emissions as well)

"Clean" is to entice the ignorant on an otherwise perfectly clean technology compared to other modern vehicles. Why is it diesel/gas owners understand gasoline emissions of the 70s are totally different, but only those who are educated on modern diesel understand it is not the diesel cars of the 80s or the big rigs with an extremely long service life (again, old diesel tech)

LPG + DIESEL is the solution!

Even the best filters cannot filter out the small, invisible particles which are characteristic for the modern diesel engines. And they are even more toxic than the "old", visible ones, since your lung cannot filter them.

The only efficient possibility to reduce particle emission is to inject LPG into the engine besides Diesel oil. This also reduces consumption. But this is only reasonable for big engines (>2.0l) or for enough mileage. Since you have to buy an extra tank and some electronics.
