CO2 report - emissions V8 3.6 liters, automatic

Hello, colleagues.

I am looking for a CO2 report for my V8 3.6 liter automatic, BJ 1989.
I need to get the individual permit in Austria!

Can someone help me?
Does anyone have such an opinion? Even if it's for Germany. As long as I can present how much CO2 the car emits!

Or does anyone know where I could get something like that for free?

There are no documents with the importer. No numbers!

Thank you
LG
