Concerns about high levels of air pollutants, together with the observed differences between the vehicle emission running under normal operating conditions and the limits specified in the homologation tests, has encouraged to conduct in Spain a study to meet the actual emissions of the circulating vehicle fleet. For this purpose Madrid metropolitan area was selected to carry on this study, considering that the characteristics of its circulating park can be extrapolated to the rest of the country fleet. The measuring technology used was optical remote sensing that allows to measure the emissions in terms of ratios of each emitted pollutant versus CO2 in the exhaust plume. Some of the most relevant results are the high levels of NO/CO2 registered for euro 5 and euro 6 diesel vehicles, and the big differences among the emissions when they are evaluated comparing the results of brands of the Spanish fleet.
