Abstract
Taking effective steps to reduce emissions of pollutants from imported used vehicles is an important policy strategy to combat climate change and maximize health and economic benefits. It is in this regard that emission concentration has been studied from imported Toyota cars at idle speed to assess their pollution potential and their compliance with existing European norms in view of proposing baseline information for a working norm in Cameroon. Data of three pollutants were collected using an AVL Ditest 5480 analyzer. Toyota vehicles were selected because they constitute the highest market share. The compiled database consists of five variables: carbon monoxide, hydrocarbons, and nitrogen oxides, and two predictors, age and mileage. The results revealed that the ages of the vehicles ranged from 3 to 19 years (M = 12.93, SD = 4.639), while the mileage ranged from 101 653 to 434 699 Km (Mean = 233 729.82, SD = 79161.37). A paired sample correlation revealed a significant relationship between age and CO emissions (r (45) = 717, p =.000), NOx (r (45) =.571, p =.001), and HC (r (45) =.490, p =.001). Mileage has a significantly higher correlation with all pollutants: CO, r (45) =.692, p =.000; HC, r (45) =.711, p =.000; and NOx, r (45) =.703, p =.000. The study provides the first evidence of emissions from imported used light-duty vehicles in Cameroon and recommended similar studies in other countries, using a variety of imported cars and pollutants so that a mitigation standard can be prioritized to maximize health and economic benefits. Meanwhile, there is a need for mandatory inspection of all newly imported used vehicles into all sub-Sahara African countries, as imported used cars and pollution seems to be intimately connected.
