Default Relative CO2/NOx emissions vs gasser sister car

Can anyone tell me what the CO2 and NOx emissions are for the ALH (A4) vs its gasser sister car is? I get grief about the NOx of my '03 Jetta TDI. I am to understand that CO2 and NOx are inversely related; if you tune for one, the other suffers...but in stock tune what are the numbers. I would like to think that while my Jetta will flunk on NOx, it may be considerably better on the CO2 than its gasser sister.
When the numbers are listed for VWs in the UK, the CO2 is part of the numbers cited...to say nothing of the Brits being able to buy the Polo <sigh>
Here's the current K Polo GTI gasser engine and Polo TDI:


MPG figures are in Imperial Gallons, multiply by .8 to get US gallons
