What is the emission standard for cars in 2011?

[SawyerDella]

Cars manufactured after July 1, 2011 comply with the China IV emission standard. For vehicles produced before July 1, 2011, they could either meet the China IV or China III emission standards. Methods to check a vehicle's emission standard are as follows: 1. Visit the vehicle management office. Bring the vehicle registration certificate to the corresponding counter and ask the staff to check for you. 2. Online inquiry. Log in to the "Motor Vehicle Environmental Protection Website" and click "This query system is only for newly manufactured vehicles. Click here to check compliance status of other vehicles". 3. Check the environmental protection label on the annual inspection sticker, which clearly indicates the emission standard at the back.
