Low Emission Zones
Increasingly cities around the world are looking to improve air quality by encouraging the most polluting vehicles, such as heavy diesel vehicles to become cleaner. By strategically developing a "zone" of Automatic Number Plate Recognition (ANPR) cameras around urban centres highly polluting vehicles are charged upon entering a controlled zone. 3M provides ANPR solutions to help minimise carbon emissions through controlling vehicle access.
London was the first Low Emission Zone (LEZ) in the UK and is the largest city in the world to improve air quality through LEZ. 3M provided Automatic Number Plate Recognition (ANPR) cameras throughout the London LEZ and continues to provide images and data for this controlled zone system.
