Viet Nam to tighten emission standards for cars from next month
VGP - From March 1, vehicle inspection centers in Viet Nam will impose stricter technical regulations on emissions for vehicles especially cars operating on Viet Nam’s roads.
The Viet Nam Register noted that vehicles reaching their inspection deadlines must meet the corresponding minimum emission standards.
To comply with the requirements, vehicle owners should carry out regular maintenance, change the engine oil and air filters, clean the fuel injectors and combustion chamber, inspect the exhaust treatment system, and use fuel that meets quality standards.
Last November, the Prime Minister signed Decision No. 43/2025/QD-TTg specifying a roadmap for implementing national technical regulations on emissions for automobiles operating on Viet Nam's roads.
Five emission levels under Prime Minister's Decision No. 43/2025/QD-TTg
| Manufacturing Period | Area of Operation | Emission Level | Equivalent Euro Standard | Effective Date |
| Before 1999 | Nationwide | Level 1 | Euro 1 | March 1, 2026 |
| 1999 – end of 2016 | Nationwide | Level 2 | Euro 2 | March 1, 2026 |
| 2017 – end of 2021 | Nationwide | Level 3 | Euro 3 | March 1, 2026 |
| 2017 – end of 2021 | Ha Noi & HCM City | Level 4 | Euro 4 | January 1, 2027 |
| From 2022 | Nationwide | Level 4 | Euro 4 | March 1, 2026 |
| From 2022 | Nationwide | Level 5 | Euro 5 | January 1, 2032 |
| From 2022 | Ha Noi & HCM City | Level 5 | Euro 5 | January 1, 2028 |
| All cars (regardless of year) | Ha Noi & HCM City | Minimum Level 2 or higher | ≥ Euro 2 | From January 1, 2029 |
Traffic emissions are among the sources of air pollution affecting public health, with over 74.3 million motorcycles and 6.3 million cars nationwide by the end of 2023.
According to the latest proposal, motorcycles in Ha Noi and HCM City must undergo emission inspections from July 2027. Emission inspections for motorcycles in other municipal cities like Hai Phong, Da Nang, Can Tho and Hue will begin from July 2028./.
