But urea injection was first developed in the EU - low sulfur/sulphur diesel fuel as well.  

That Business Week article is so full of holes, it's swiss cheese.  First off, it isn't NO2 specifically that is the problem, but a variety of nitrogen oxides, and the way anybody in science rights that is NOx.  Then there's the bafflegab about different NOx standards for diesel powered cars - which isn't so, EU standards for car emissions are fuel-neutral.  And, having travelled in London, it's not the diesel cars that are the problem, it's the trucks/lorries.

Overall, I'd have to say another 'puff piece' by Business Week for the North American gasoline industry!
