Action 6.1: Annual engine emission testing
One way to get rid of “high-emitting” vehicles is to measure black carbon emissions in regular schemes for testing of environmental performance during motor vehicle inspections – with the important action of banning the use of the vehicle until the engine exhaust system meets certain black carbon emission standards. Alternatively, one could add control of black carbon emissions as a part of the manufacturer’s engine maintenance programmes or engage in a roadside engine exhaust campaign. An example is recent vehicle inspection initiative recently in Spain following evaluation and testing of the Spanish case.
