Abstract
The longevity of imported used vehicle determines urban outdoor air pollution and affects government’s regulatory policy measures to balance the benefit of used vehicle usage and its negative externalities. This paper estimates the life expectancy of vehicles in Ethiopia for a maximum of 30 years. The study used four different models to determine the total vehicle stock, survival rate and scrap rate of vehicles at different age and the total emission respectively. The models support different estimation, where there is difficulty to find actual data related to scrap vehicles. The total emission calculation serves policy makers to make a learned and informed decision that improves urban air quality.
