How to find a car's NOx value quickly?

I'm looking at importing a car and this NOx is confusing me. Is there a quick way of finding a NOx value for a car?

Hi Cathal,

Short answer, no. There are some online listings of NOx values, but they’re patchy to say the least. The best you can get is a ballpark figure, but the only one that Revenue will accept will be that printed on the vehicle’s Certificate of Conformity.
