What happened
The European Commission has adopted Delegated Regulation (EU) 2026/1214, amending Annex III of the Euro 7 Regulation, Regulation (EU) 2024/1257. The change updates the conditions used to assess compliance with brake-particle emission limits.
For M1 and N1 vehicle categories, Table 4 now refers to UN Regulation No 179 rather than UN Global Technical Regulation No 24. The new UN rule concerns laboratory assessment of brake emissions from light-duty vehicles.
According to the Commission, Regulation No 179 incorporates technical developments and evidence collected through Euro 7 brake testing. It provides for more harmonised testing conditions, higher-precision measurement of PM10, PM2.5 and particle numbers, testing of brakes fitted with passive or active emissions-reduction filters, and whole-vehicle brake-emissions calculations.
Why it matters
Manufacturers and type-approval teams working on affected light-duty vehicles should update their Euro 7 brake-particle compliance plans to use the method specified in UN Regulation No 179. The Commission says the UN regulation comprehensively addresses light-duty categories and supports harmonisation of the applicable standard.
The measure also concerns Euro 7ext vehicles under Article 5(2) of the underlying Euro 7 regulation.
Entry into force
The delegated regulation was adopted on 9 June 2026 and published in the Official Journal on 3 September 2026. It takes effect on the twentieth day after publication and is binding and directly applicable in every EU Member State.
