Below you will find answers to your questions about the Brussels-Capital Region Low Emission Zone so as to travel with complete peace of mind.

LEZ and the environment

How will the LEZ impact air quality?

The LEZ helps to reduce emissions by gradually banning the most polluting vehicles from the Brussels-Capital Region.

The first results of the LEZ are encouraging. In just six months, the number of older diesel vehicles on the road has fallen significantly and the quantity of NOx and PM2.5 emitted by cars on the road has also decreased. These results are detailed in the 2022 evaluation report.

In the medium term, air quality is expected to improve across the country due to the LEZ. Brussels Environment expects that air quality standards for NO2 will be met at all measuring stations in the Region between 2020 and 2025, as outlined in the study on the expected effects of the LEZ. This will improve the quality of life and the health of all Brussels residents.

Does the LEZ prevent global warming?

A distinction is made between greenhouse gas emissions such as CO2, which contribute to global warming, and fine particulate air pollutants, nitrogen oxides or ozone, which are harmful to human health. The purpose of the LEZ is to reduce emissions of fine particulate matter, nitrogen oxides and other pollutants that have a negative impact on our health. The Brussels-Capital Region is implementing other measures to tackle greenhouse gases, such as grants to insulate housing.

However, the LEZ will also help to drive down CO2 emissions where people whose vehicle is subject to restrictions travel to Brussels other than by private car (on foot, by bicycle, public transport, shared vehicles). Moving away from private cars is an effective way of improving air quality, while taking action against climate change.

What other measures are being taken by the Region to improve air quality?

The Brussels-Capital Region Government is taking action in many areas of human activity that involve atmospheric pollutant emissions. This is why the Air Climate Energy Plan was adopted on 2 June 2016.

Besides the introduction of the LEZ, the plan also sets out measures to improve the energy efficiency of buildings, for enhanced air quality monitoring, the generation of energy from renewable sources, and for economic consumption patterns and product use.

Why reduce air pollution caused by road transport?

Road transport is responsible for air pollutant emissions which degrade air quality. In Brussels, road transport is the main source of emissions of nitrogen oxides (NOx), fine particulate matter (PM2.5) and black carbon (BC) particles.

These emissions contribute to the deterioration of air quality. For example, in Brussels, concentrations of particulate matter (PM2.5) and nitrogen dioxide (NO2) exceed the thresholds set by the European Union (for NO2) and recommendations by the World Health Organization (for PM2.5), which may result in health problems for the entire population.

Poor air quality is the cause of premature deaths and major health problems (respiratory and cardiovascular diseases, etc.) and especially affects the most vulnerable people, such as children and the elderly. In 2016, Belgium recorded 7,600 premature deaths due to exposure to particulate matter, 1,600 premature deaths due to exposure to nitrogen dioxide and 180 

Why do restrictions apply to the oldest vehicles?

On average, older vehicles emit more pollutants that are harmful to health (nitrogen oxides, particulate matter, etc.) than newer vehicles. This is why access to the LEZ is restricted according to the age of the vehicle.

Why are restrictions more stringent for diesel vehicles?

On average, diesel vehicles emit more pollutants (nitrogen oxides in particular) than petrol vehicles. The World Health Organization (WHO) classes exhaust gases from diesel engines as carcinogenic to humans because they contribute to an increased risk of lung cancer. For these reasons, access restrictions target primarily diesel vehicles.

The boundaries of the Brussels LEZ

What territory is covered by the LEZ and how to recognise it?

The territory of the LEZ affects all 19 municipalities across the whole of the Brussels-Capital Region. The Ring and access roads to transit car parks are excluded.

Nearly 300 road signs have been installed to identify the LEZ at the regional boundary. They indicate that you are entering or leaving the Low Emission Zone. You must only enter the LEZ with vehicles which comply with the access criteria.

Other LEZ in Belgium and Europe

Do other cities in Belgium also have a LEZ?

The city of Antwerp has a LEZ since 01/02/2017 and since 01/01/2020, the city of Ghent has also a LEZ.

However, it is important to make some distinctions. The criteria to access the Flanders LEZ are not quite the same as those of the Brussels-Capital Region. You can find more information on low emission areas in Flanders on the Flemish Region website (operation, registration form for vehicles registered abroad, exemption application form, pass purchase form, etc.).

Do LEZs exist in other countries?

Many European countries have introduced a LEZ in their major cities. They can be found in most major German cities, and in the Netherlands and Italy. London has a LEZ, and Paris has just implemented the principal via CritAir stickers.

Respecting privacy

Is privacy guaranteed?

The Brussels Regional Public Tax Service (Brussels Taxation) uses certain data to ensure compliance with the LEZ rules. For more information, visit the Privacy page.

My vehicle

Is my vehicle compliant and until when?

The regulation concerns (excluding exemptions) the following vehicles, whether they are registered in Belgium or abroad:

  • Cars (vehicle category M1 on the registration document).
  • Vans ≤ 3.5 tons (vehicle category N1 on the registration document).
  • Minibuses and coaches (vehicle category M2 and M3 on the vehicle registration document)

A vehicle may or may not be used in the LEZ depending on its fuel type, category and Euro standard. In certain cases, if the Euro standard is not shown on the vehicles registration document, the first registration date will be used.

You can check the compliance of your vehicle by entering the licence plate and the date of first registration, or by entering the vehicles technical data into the simulator:

Check your vehicle

My vehicle is prohibited from driving in the LEZ: are any subsidies or allowances available?

Allowances are available for both individuals (Bruxell'Air allowance) and professionals (replacement allowance for a polluting commercial vehicle).

Can my car be immobilised or seized following a police check if not compliant with the LEZ access criteria?

In the event of an inspection of a prohibited vehicle and if the fine cannot be paid immediately, the police may impound your vehicle.

How can I contest my fine?

You can submit a complaint with your reasoning. It must be sent to the Brussels Taxation Administration within 37 days of the date on which the fine was sent.


Alternatives to the car

What alternatives to the car are available to get around Brussels?

Cars are not the ideal means of transport in the Brussels-Capital Region. Apart from buying a day pass or having an exemption (granted under certain conditions), here are some other alternatives to using the car:

Euro standard

What is the Euro standard of my vehicle?

The Euro standard is a European environmental standard with which vehicle engines must comply. The higher the Euro standard of a vehicle, the lower its emissions. A vehicle’s Euro standard determines, according to the fuel it uses, whether or not it is permitted to access the low emission zone (LEZ).

Is the Euro standard shown on the vehicle’s registration document. If the Euro standard is not shown on the vehicle’s registration document, the first registration date will be used. This is also shown on your vehicle’s registration document.

It is also possible to check the EURO standard of your vehicle using the COC code (.pdf) on the vehicle’s certificate of conformity.

How can I find out the Euro standard of my vehicle if it is not indicated on my vehicle registration document?

If the Euro standard is not shown on the vehicle’s registration document, the first registration date will be used.If the Euro standard is not shown on the vehicle’s registration document, the first registration date will be used.
