Which vehicle values do I have to take into account for the CO2 tax?

The CO2 tax is calculated in accordance with the CO2 Ordinance on the basis of the COC (Certificate of Conformity). The manufacturer’s document provides exact values about your vehicle. The Federal Office of Energy, also has its own CO2 emission calculator Astra.


empty weight

Under point 13.2 “Actual mass of the vehicle” you will find the unladen weight.

Rule of thumb: The higher the weight, the higher the CO2 emission may be.


You will also find the exact CO2 emissions on the COC. The CO2 values are shown in urban, extra-urban and combined form. For the calculation we need the combined value.
