Chinese emission standards for new passenger cars and light-duty commercial vehicles are based on European regulations. Light-duty vehicle categories are based on the EU classification with some changes:

  • Type 1 vehicles: M1 vehicles for no more than 6 passengers including driver, and GVW ≤ 2.5 ton,
  • Type 2 vehicles: Other light-duty vehicles (including N1 light commercial vehicles) further divided into three classes based on the reference mass (RM):
    • Class I: RM ≤ 1305 kg
    • Class II: 1305 kg < RM ≤ 1760 kg
    • Class III: RM > 1760 kg

Emission limits are shown in Table 1 for gasoline vehicles and in Table 2 for diesel vehicles.

The implementation schedule is listed in Table 3. The nationwide dates generally refer to new type approvals—first registration of existing vehicle models is typically allowed for one more year. The nationwide China 5 regulation [2941] provides one implementation date, applicable to both new type approvals and to first registration.

New gasoline vehicles must also meet an evaporative emission limit of 2 g/test (SHED).

Durability requirements are 80,000 km for Euro 3, and 100,000 km for Euro 4.
