The rapid growth in motor vehicle activity in Owerri municipal and its environs contributes to high level of urban air pollution, among other adverse socioeconomic, environmental, health, and welfare impacts. Vehicular emissions are significant contributors to ambient air pollution, especially in urban areas. This paper reviews the status of vehicle emissions and their health impacts. The implications of emissions such as hydrocarbons, oxides of nitrogen, carbon monoxides, carbon dioxide among others have been discussed. Various methods of effective control of vehicular emissions have also been presented. To achieve this , the trend of vehicles registered within Owerri spanning for a period of ten (10) years were obtained from Imo State Licensing office. This secondary data indicates that the number of registered vehicles has increased tremendously over the years and this rise has significantly increased the vehicular emissions in the study area. Finally, the paper presents preventive measures and sustainable solutions such as vehicle inspection, enforcement of legislations, effective refuse collection and evacuation and steady supply of electricity to stop use of gasoline generators among others to ensure safe environment for the population to live.
