Vietnam Motorcycles Emissions standards

History

In 2005, Vietnam issued Government Decision No: 249/2005/QĐ-TTg, which mandated emissions limits for motorcycles and mopeds, referred to as Type 2 standard (equivalent to the Euro 2 standard). The Decision required new manufactured, assembled, and imported motorcycles and mopeds to meet Euro 2 standard in 2007.

The Type 3 (Euro 3) standard was implemented in 2017 via Government Decision No. 49/2011/QĐ-TTg issued in 2011.

The Ministry of Transport (Bộ Giao Thông Vận Tải) is responsible for reducing emissions from new and in-use motor vehicles, overseeing testing, and implementing emission-related regulations.

Technical Standards

Emission standards for two-wheelers are outlined in the table below. For Euro 3 emission standards, manufacturers can opt for either ECE R40 or WMTC as their test cycle, and should comply with their respective emission targets.
