well that was a bunch of the standard "green" techno-babble that didn't answer the question at all Exalteze.
i believe the question was "who is doing the certifying of your truck"?
not the standards it has to meet
not the sales babble talk
not 'green' 'zero carbon' theory
not a lesson on how ammonia is being used in the development of DEF (which i'm sure is what you were insinuating in your small lecture about ammonia)

who have you gotten to certify your machine? ( i believe chrisk asked that and i just highlighted it myself)
