In areas that have high pollution, diesels will need to have emissions testing as well as gasoline cars. Diesels are not "clean" just as gasoline is not "clean" and this needs to be taken into account. As for the CAFE standards issue noted in the article, I think the car manufactures listed are basically saying they don't want to do the R&D to improve to meet the increased CAFE standards.

Larger diesels, like the VW Passat and Mercedes now have Urea tanks that have to be refilled every 10,000 miles. The smaller diesels are getting efficient enough that they're actually meeting emissions by the fact that they use so little fuel that they produce less emissions.
