The diesel clatter much quieter than before, like I said, and isn't always obvious at first "hearing". Maybe Californians are such snobs that they won't accept a diesel in a luxury car. That may even have been true here, but READ MY LIPS (well, the pearls of wisdom dripping from my and others' keyboards). Sales of top BMW and Merc cars with diesel engines are relatively high and rising, for whatever reason. Merc has brought out a CLK with 2.7 l diesel engine and one of the participants in this group, living in NL (Netherlands) wrote about it. Inconceivable just a few years ago.
What CARB (appropriate name) does is interesting but does it always set a world trend?
Am not sure what CNG is (but it sounds like the LPG we have here (or, more precisely, in NL and other countries), a form of liquefied gas. Yes, very clean as it;s pure CHO. The UK government gives a small subsidy for conversions but it isn't widespread because there are few filling stations.
Whacking big tank in the boot/trunk taking up space and 20% greater fuel consumption. Right now the fuel is cheap but you can bet your bottom dollar that taxes will be piled on if it becomes widely used (outside the US anyway).
