Motor vehicle emissions have shown to be of hazardous health influences. Its impact is amplified in urban areas such as the Greater Cairo Region (GCR). It is reported that the number of motor vehicles in Cairo is increasing at a rate of approximately 200,000 per year reaching 6,700,000 vehicles in year 2012, due to improving living style and the increase on economic growth; consequently, reducing motor vehicle emissions has become a major objective of environmental management activities in Egypt. In this context, Egypt's strategies include adoption of emission standards for new vehicles, enforcing emission standards for in-use vehicles, introducing proper low emissions techniques for gasoline and diesel powered engines, and encouraging cleaner alternative fuels, the main objective of the research is to illustrate the mitigation measure for the vehicles exhaust emissions.
