I can live with that. So how come it wont meet your emissions requirements?
I only pay £20 road tax because the emissions are supposed to be so low.

From what I understand, one government (either here, or over there... not sure which) focuses more on particulate emissions while the other wants lower levels of particular gasses emitted.

And then there's another challenge for diesels--stricter U.S. emission regulations. The 50-state light-duty vehicle limit for emissions of nitrogen oxides is 0.07 grams per mile. In Western Europe, the limit is 0.29.

Unfortunately that's the most specific requirement comparison I could get right away.
