- €5 per mg/km for NOx emissions over 80mg/km
- Maximum surcharge: €5000
- Only applies to diesel vehicles
- Euro 6d and 6d-TEMP are exempt

How to Check Your Vehicle's Euro Standard
Finding your vehicle's Euro standard is crucial for accurate NOx calculations:
- Vehicle Registration Certificate: Check section (P.3) for emissions standard
- Manufacturer Website: Use VIN lookup tools
- Dealer Documentation: Original purchase paperwork
- NCT Certificate: May list Euro standard
Pro tip: If you can't find the Euro standard, use the registration year as a guide. Most cars registered after September 2020 are Euro 6d compliant.
