Since motorcycles are responsible for the largest proportion of vehicular carbon emissions in Viet Nam, decision-makers should prioritize improving fuel efficiency and encouraging the use of clean energy to decrease air pollution and achieve the country’s Intended Nationally Determined Contribution (INDC) to fight climate change as well.

As of 2015, the number of vehicles in Viet Nam was approximately 47 million, of which motorcycles accounted for nearly 96%. The number of motorcycles is rapidly increasing at an annual rate of about 12%, especially in Viet Nam’s five major cities: Hanoi, Ho Chi Minh City, Da Nang, Hai Phong, and Can Tho.

In Viet Nam, motorcycles dominate the urban transport system and are attractive to most people, as they provide higher accessibility and are a more affordable and convenient form of individual transport.

However, the high level of motorcycle dependency in cities also causes a number of transport problems.
