This guidance provides relevant local air quality management policy and technical guidance on Low Emission Zones. It provides information on methods for implementing these zones, practical issues that have arisen and advice on appraising costs and air quality benefits.

Low Emission Zones (LEZs) are areas where the most polluting vehicles are restricted from entering an area. This means that vehicles are banned, or in some cases charged, if they enter the LEZ when their emissions are over a set level.

They are often the most effective measure that cities can take to reduce air pollution problems in their area. The emissions that are aimed to be reduced by LEZs are mainly fine particles, nitrogen dioxide and indirectly ozone.

Further information on Low Emissions Zones can be found on the Low Emission Zones in Europe website.
