What is even better is that many HD applications do not even need to meet the same standard on a PPM basis, why go after the low hanging fruit, right?
This is why I have long held that our emissions standards are not relevant anymore and need to be altered to address the largest sources of pollution upstream and consumer level.
We need to focus more strongly "nationwide" (not CA which is its own nation) on reducing Co2, period. Improved exhaust makeup can be driven by better fuel but reducing the amount of fuel consumed needs to be job 1 in a close tie with reducing industrial pollution sources.
Alas I digress.
