Car Exhaust and environmental policies: The Potential of Remote Sensing


Madrid’s roads will start testing a new radar that measures the emissions of moving vehicles. In just one second it is able to know how much pollutant gases leave the exhaust pipe. In less than a second, this device measures what it is coming out of its exhaust pipes of the vehicles passing in front. It identifies the emissions of each car in real time. The radar has one ultraviolet and one infrared lamps. Thanks to them, it perceives what gases and in what exact quantity each vehicle is emitting. It records CO, CO2, NO2, PM and HC.

European Commission confirms that this system will be useful after Dieselgate scandal. European Commission confirms that this system will be useful after Dieselgate scandal. This project will allow to compare real emissions and certified emissions at the moment of manufacturing. Next two and a half years this radar will rotate though Madrid`s roads.
