Low Emissions Zone
& Clean Air Zones

Strict Air Quality Standards for Cities


The Low Emissions Zone (or simply "LEZ") was introduced by Transport for London on February 4th, 2008 and covers most of Greater London. The aim of the LEZ was to reduce pollution levels in Central London to help the city meet its European Union air pollution obligations—specifically the EU Air Quality Framework Directive

The LEZ required commercial diesel powered vehicles operating within the zone to pay a daily fee unless their vehicles meet certain emission standards. When the LEZ was first introduced in 2008 operators of HGVs were required to meet Euro III standard for the emissions of particulate matter (PM). This was further tightened in 2012 to require Euro IV "PM" Emissions standards to be met in order to drive within the LEZ without charge.

The London LEZ is enforced and monitored by an extensive network of Automatic Number Plate Recognition (ANPR) Cameras which interface directly with the DVLA's database.

Vehicles entering or moving around the zone are checked against the records of the DVLA to enable Transport for London to pursue owners of non-compliant vehicles for which the charge has not been paid. (For vehicles registered outside of Great Britain, an international debt recovery agency is used to obtain unpaid charges and fines.)

Introduction of an Ultra Low Emission Zone for London

From September 2019 London will introduce an "Ultra Low Emission Zone – ULEZ" within the existing Congestion Charge Zone (CCZ) where all cars, vans, minibuses, buses, coaches and heavy goods vehicles (HGVs) will need to meet even tighter exhaust emission standards (ULEZ standards) to travel without charge in central London.

The emissions standards set for cars, vans and minibuses will be Euro 4 (petrol) and Euro 6 (diesel), while diesel powered HGVs, Buses and Coaches will be required to meet the strict EURO 6 Emission Standard for Particulate and NOx.

Not surprisingly, most new heavy duty diesel vehicles being sold now are already compliant with EURO 6, but there are many thousands of existing vehicles on the road that do not comply with the EURO 6 standard.

If your vehicle does not meet the ULEZ emissions standards and the daily charge is not paid, a Penalty Charge Notice (PCN) will be issued payable by the registered owner or operator. This penalty is in addition to any CC or LEZ penalties received.

For cars, vans and minibuses this will be £130 (reduced to £65 if paid within 14 days). For HGVs, coaches and buses this will be £1,000 (reduced to £500 if paid within 14 days).

Fees payable for non-compliance of the ULEZ standards are over and above those required for LEZ or Congestion Charge.

If you operate a vehicle that is not EURO 6 compliant, you have several options such as avoiding the ULEZ, paying the fee, purchasing a new compliant vehicle or retrofitting your vehicle with an approved Emissions Abatement technology.

As the ULEZ emissions standard also calls for the reduction of NOx/NO2 as well as PM10/PM2.5, the most cost effective "Emissions Abatement Technology" that can be retrofitted to existing vehicles for compliance will be the "SCRT" Technology.

For the vast majority of operators, this will be the most cost-effective option.

In addition to London's uLEZ, a further five 'Clean Air Zones' will be in force in other UK cities within the next 3 years, with a further 10 within the next eight years.

Although the emissions standards for the new Clean Air Zones have not yet been finalised, it is highly likely that they will follow London's example and require EURO 6 as a minimum standard.

GreenUrban's ecoNOxt™ System can be installed into existing vehicles to allow them to comply with the EURO 6 standard.
