Emission standards for passenger cars
Exhaust is much less harmful today than it was a decade ago, thanks to emission standards.
Exhaust is much less harmful today than it was a decade ago, thanks to emission standards.
Emission standards for passenger cars and light commercial vehicles are summarized in the following tables. Since the Euro 2 stage, EU regulations introduce different emission limits for diesel and gasoline vehicles. Diesels have more stringent CO standards but are allowed higher NOx. Gasoline vehicles are exempted from PM standards through the Euro 4 stage (Euro 5 proposal introduces PM standards for lean-burning gasoline cars).
All dates listed in the tables refer to new type approvals. The EC Directives also specify a second date—one year later—which applies to first registration (entry into service) of existing, previously type-ap****** vehicle models.
