The emission of motorized road vehicles is shown to depend heavily on the quality of vehicles, fuel, speed, driver, congestion and roads. Cars and motorbikes in Vietnam include many types that have been used for many years and are not regularly maintained, low fuel efficiency, high levels of toxic substances and dust in emissions.
