Vietnam: Motorcycles: Emissions

Overview

Currently, Euro 4 standards are in place for gasoline vehicles in Vietnam, and Euro IV standards for diesel vehicles will be in place in 2018. The table below shows that there are slightly different parameters for two vs three-wheeled vehicles.

Standard type

History

Vietnam’s current emissions limits for two- and three-wheelers, referred to as Type 2 standards, are equivalent to Euro 2 standards. These regulations were implemented via Government Decision Số: 249/2005/QĐ-TTg, issued 10 October 2005. The Decision required two- and three-wheelers to meet Euro 2 standards beginning 1 July 2007. The Euro 3 standard was implemented on January 1st, 2017.

Future Policies

Type 5 – Vietnam will skip Type 4 (~Euro 4) standards and move ahead to Type 5 (~Euro 5) Standards starting 1 January 2022.¹

The Ministry of Science and Technology (Bộ Khoa học và Công) is responsible for reviewing, developing, and promulgating standards in accordance with the implementation schedule described in the regulations.

The Ministry of Transport (Bộ Giao Thông Vận Tải) is responsible for:

coordinating with the Ministry of Planning and Investment and the Ministry of Finance to improve technical capacity, facilities, equipment performance monitoring; to control motor vehicle emissions in traffic; and to oversee testing;
coordinating with ministries, branches and People’s Committees of provinces and cities to reduce emissions from motor vehicles;
organizing the implementation of the regulations.

Technical Standards

Emission standards for two- and three-wheelers are outlined in the table below.

**Emission Standards for Two- and Three-wheelers**
Standard	Date	Size/Fuel	Wheel Configuration	CO (g/km)	HC (g/km)	NOx (g/km)	PM (g/km)	Test Cycle

Notes: 1. Test cycle: ECE R40 (with emissions measured for all six modes – sampling starts at T=0). 2. Test cycle: ECE R40 +EUDC (emissions measured from all modes – sampling starts at T=0), with the maximum speed of 120 km/h.
