Where to get NOx data for cars?

Where/how can I find the NOx emissions on a used car?

Thanks

Hi David,

Short answer: it’s not easy. The best online source for NOx figures is the British government's Vehicle Certification Agency (VCA), which has an online database of fuel economy, CO₂ and NOx figures. Sadly, it’s not an exhaustive resource — some models are not covered. The only source that really matters, as in the one that will be accepted by Revenue as the legally official NOx figure, is the one on a car’s Certificate of Conformity, which is kind of like a birth cert for a car. Sadly, you’d need to get the CoC for the specific car you’re looking at buying, which is not the easiest.
