Low Emission Zones in Europe: Requirement, Enforcement and Air Quality

The objective of low emission zones (LEZs) is to reduce particulate and NO₂ emissions, by preventing or limiting access for the most polluting vehicles. Initially, the measure was implemented to reduce particulate matter, mainly from heavy duty vehicles. Now the focus is also on reducing NO₂ emissions. The requirements are generally more stringent for diesel vehicles than for petrol vehicles. LEZs was previously used primarily to reduce the use of older heavy duty vehicles, but several countries have now also introduced requirements for other categories of vehicles. An overweight of countries that have LEZs, have implemented the measure because they did not comply with the EU Limit Values for local air quality. Effect of LEZs on air quality is difficult to evaluate because of several methodical challenges. With improved knowledge on real emissions from road traffic the future LEZs can be better adapted to the needs of the cities.
