[Vwdiesel] CNG v. Diesel

[Scott Kair]

    It's been a recurring flap of late.  Apparently even CARB admits that
running clean (newer) Diesels can be done for about half the overall cost of
CNG retrofits. The DC metro bus system wanted to convert to CNG, but the new
Diesels were reducing pollutants sufficiently that the governing board
decided to spend the money slated for beginning CNG conversion on
maintaining the subway system. See, for starters:
