Understanding RDE2 Standards

Real Driving Emissions 2 (RDE2) is a crucial standard for diesel vehicles that affects both environmental impact and taxation. This guide explains what RDE2 means, how it affects your car tax, and why it matters when choosing a diesel vehicle.

Key Points
RDE2 compliant diesel vehicles are exempt from the diesel supplement in the first-year tax rate, potentially saving owners hundreds of pounds.

What is RDE2?

RDE2 (Real Driving Emissions 2) is a testing procedure that measures a vehicle's emissions in real-world driving conditions, rather than just in laboratory settings. Key aspects include:

  • Testing under various road conditions
  • Different driving styles and speeds
  • Various weather conditions
  • Focus on nitrogen oxide (NOx) emissions

Tax Implications of RDE2 Compliance

The RDE2 standard has significant implications for vehicle taxation:

  • Non-RDE2 compliant diesels pay a higher first-year tax rate
  • The supplement can be up to £520 more in the first year
  • RDE2 compliant vehicles avoid this additional charge
  • Standard rates after the first year are unaffected

How to Check if Your Car is RDE2 Compliant

To determine if your diesel vehicle meets RDE2 standards:

  1. Check your vehicle's documentation or V5C registration certificate
  2. Contact your vehicle manufacturer
  3. Look for "Euro 6d" or "Euro 6d-temp" certification
  4. Verify the registration date (most diesel cars registered from 2020 are compliant)
Important Note
Don't assume a newer diesel vehicle is automatically RDE2 compliant. Always verify with official documentation.

Benefits of RDE2 Compliance

RDE2 compliance offers several advantages:

  • Lower first-year tax rates
  • Better environmental performance
  • Future-proofing against emissions regulations
  • Potentially higher resale value

Future Implications

Understanding RDE2 standards is increasingly important as:

  • Emissions regulations continue to tighten
  • Clean air zones become more common
  • Vehicle taxation increasingly reflects environmental impact
  • Consumer awareness of emissions grows

Conclusion

RDE2 compliance is a crucial factor in diesel vehicle taxation and environmental impact. When choosing a diesel vehicle, checking its RDE2 status could save you money and help you make a more environmentally conscious choice.
