Euro Emission Standards
Euro emission standards set limits for pollutants from new vehicles sold in the EU.
What is Euro Emission Standards?
They cover CO, HC, NOx and particulates. Euro 6 has applied to new cars since the mid-2010s. Euro 7 was adopted in 2024. Euro 7, adopted in 2024, adds rules for brake particles, tyre wear and battery durability in electric cars. Diesel and petrol engines have historically had different limits for NOx and particles under the same Euro stage. The Euro class of a vehicle affects taxes and access to low emission zones in some countries.
How it works
Manufacturers must meet the limits in type approval tests.
Why it matters for your car
Low emission zones often use Euro classes. Check the class in the registration documents.
