There is also the higher cetane rating in Diesel fuel nowadays that also reduces considerably the amount of soot.
Anyway, with heavier taxes on old Diesels and the reliability issues from the emissions-control devices in the newer ones, it's not hard to understand why CNG and biomethane are increasing its market share in Europe...

The black smoke is not the same as the fine particle emission, which is invisible. The large particles are heavy so they disappear quickly from the air, making them less dangerous than the fine stuff.
Biodiesel gases also contain fine particles. Yet as biodiesel consists mainly of carbohydrates pollutants containing other elementas are absent.
