Core elements of the proposed Euro 7 regulation for light-duty and heavy-duty vehicles

Euro 7 is now a single legislative act that covers all on-road vehicles, both light and heavy-duty. This change harmonizes the regulation in several aspects, but different tests and criteria will be applied to both categories.

• Light-duty vehicle emissions are specified at Euro 6 levels (harmonized to the lowest current levels for gasoline and diesel) with the following additions:
  • PN > 10 nm replaced PN > 23 nm
  • PM and PN regulations extended to all gasoline vehicles, not just direct injection
  • Fuel evaporative gases for LDVs will be subject to sricter regulations
• Heavy-duty vehicle emissions limits are reduced with the following additions:
  • PN > 10nm replaced PM Number > 23 nm
  • New components NMOG, NH₃, CH₄, and N₂O have been added for laboratory testing and RDE testing
  • NH₃ changed from concentration regulation to mass regulation for RDE testing
• Continued consideration of regulating HCHO Major changes in evaporative gas testing
  • The evaporative gas regulation for refueling, which was proposed in the initial proposal, has been eliminated in the final version.

The start date of the Euro 7 regulation is as follows;

In addition, related implementing acts (implementing acts) will be adopted in the future, and it is expected that implementing acts for LDV will be adopted by 2025/5/29 and for HDV by 2026/11/29.
