The eco surcharge is a component of the registration tax, which is calculated based on the CO2 emissions of the vehicle.
It is payable once, when registering a new or second-hand vehicle that emits 146 g or more of CO2 per kilometre in Wallonia.
The eco surcharge varies between €100 and €2,500, depending on the vehicle’s CO2 emission level (g/km). There are 12 vehicle-emissions categories: see “Learn more”.
In the event that the vehicle is cancelled or changed, the eco surcharge is not refunded; the same applies to the registration tax.
The owner of the taxable vehicle, who is indicated on the registration certificate, whether they are an individual or a legal entity.
The eco surcharge is requested in conjunction with registration tax.
The eco surcharge is automatically calculated based on data provided by the DIV.
If our services do not have information about your vehicle's CO2 emissions, we will send you a letter inviting you to send us this information. If you do not have this information on your compliance certificate, you can provide a copy of your log book, which shows this information, or an official certificate from the manufacturer, which is available through your agent. If the CO2 emissions level is not indicated, this certificate must mention the vehicle’s average consumption in litres.
If the number of grams of CO2 per kilometre is not known, even after consulting the FEBIAC database, the tax is calculated based on a default CO2 emissions level of:
- 205 g/km for vehicles that use petrol;
- 196 g/km for vehicles that use diesel.
This corresponds to a surcharge of €600.
In order to ensure fair treatment of taxpayers, the Court of Auditors recommends checking that the vehicle's CO2 emissions level does not exceed the default emissions level that is applied by any other means possible, such as the FEBIAC database.
The new or second-hand vehicle that is placed on the road must have a CO2 emissions level that is greater than, or equal to, 146 g/km.
For “old-timer” cars (which were registered more than 30 years ago) and cars with a special licence plate 1 - Oxx-xxx, the eco surcharge is “0”. The same applies to company cars that are leased.
For large family cars and those that use LPG, the eco surcharge is reduced as follows:
1- Large family cars:
Provided that the vehicle emits less than 226 g of CO2 per kilometre, the taxpayer receives a one-category allowance if they have three dependent children aged under 25 and a two-category allowance if have four or more dependent children under 25 on the date on which the vehicle is first used.
Example: a vehicle belongs to emissions category 12 (emissions of between 196 and 205 g of CO2 per kilometre), for which the eco surcharge is €600.00. For a family with three children, the same vehicle will be considered as belonging to emissions category 11 (emissions of between 186 and 195 g of CO2 per kilometre), for which the eco surcharge is €500.00.
2- Vehicles that use LPG:
The owner of a vehicle that uses LPG receives a one-category allowance.
The two benefits are cumulative.
