Abstract:

Motorcycles and mopeds are significant modes of transportation in Vietnam. In 2023, more than 74 million two-wheelers were registered in the nation, comprising over 90% of the motorized vehicle fleet. Vietnam's two-wheeler market ranks second in new sales within the ASEAN area, following Indonesia. The nation's dependence on fossil fuel-powered automobiles has significantly deteriorated air quality, resulting in a rise in respiratory ailments and other health issues.   

Vietnam's revised Nationally Determined Contribution (NDC) under the Paris Agreement includes a promise to regulate fuel consumption for newly manufactured, assembled, and imported motor vehicles to mitigate greenhouse gas emissions from the transportation sector. Considering the prevalence of motorcycles and mopeds, such initiatives are essential for Vietnam to achieve its climate objectives and enhance air quality.   

This study gathers and examines the attributes and baseline fuel consumption of two-wheelers sold in Vietnam from 2017 to 2021. This study's results will underpin the advancement of compulsory fuel consumption regulations for two-wheelers to mitigate overall CO2 emissions in Vietnam's transportation sector.
