Diesels have much better burning efficiency, than gasoline engines, so less fuel by-products end in the exhaust, or need to be after-burned in catalytic converter.
However each engine will pass some poisons, that are in the fuel to start with.
In US we still have diesel fuel poisoned with sulfurs and although Europe changed that about decade ago, upgrading the fuel in US is delayed for years.
