Low emission zones across Europe.

What a Low Emission Zone is.

A Low Emission Zone, LEZ, is a designated area where only vehicles meeting a minimum emissions standard are allowed to drive. The name changes from country to country, the proof you need changes too, and so do the fines. What does not change is how they catch you: an ANPR camera reads your number plate, checks it against a national register, and a fine is issued automatically. You do not need to be stopped by a police officer. You may not even realise it has happened until a letter arrives weeks later.

For UK motorhome owners, the schemes most likely to affect a European trip are Crit'Air in France, Umweltplakette in Germany, the Belgian LEZ covering Brussels, Antwerp and Ghent, the Dutch Milieuzone, and the ZTL and ZBE zones across Italy and Spain. Austria, Sweden and Norway generally apply emission restrictions to commercial vehicles only, so privately registered motorhomes are usually unaffected, but always check before you travel.

Euro standards at a glance

Your engine's Euro rating is the key number. It determines which zones you can enter and which stickers or permits you are eligible for. You will find it on your V5C. If your vehicle is older and it is not listed, you can work it out from the first registration date.

France, and the Crit'Air vignette.

The Crit'Air vignette is a small round sticker you fix to the inside of your windscreen. It tells French authorities which emissions category your vehicle falls into. Permanent restricted zones, known as ZFE-m, already cover Paris, Lyon, Marseille, Strasbourg, Toulouse, Montpellier, Rouen and Reims, and more cities are added regularly. Temporary zones, called ZPA, are triggered on high-pollution days and tend to appear most often in summer.

From January 2026, Crit'Air 3 vehicles, diesel engines registered before 2011, are barred from most ZFE-m zones during weekday daytime hours. If your motorhome carries a Crit'Air 2 sticker, Euro 5 or Euro 6 diesel, you are fine for most cities until at least 2028. Check the current rules before any trip.

How to apply

Go directly to certificat-air.gouv.fr. That is the only official French government portal. Any other site offering to get you a sticker is a reseller charging a premium for the same process. Upload a copy of your V5C and pay EUR 4.61, which includes postage to a UK address. Email confirmation usually comes within 48 hours. The physical sticker arrives in around 4 weeks, so order well before your departure date. Fix the sticker to the inside of your windscreen, bottom-right corner.

Germany, and the Umweltplakette.

The Umweltplakette is a circular sticker you display on your windscreen to show your vehicle meets the emissions standard required for German low-emission zones, called Umweltzonen. Around 80 cities operate these zones, including Berlin, Munich, Hamburg, Cologne, Stuttgart, Frankfurt and Leipzig. There are three sticker colours: green (category 4), amber (category 3) and red (category 2). The amber and red stickers no longer get you into any zone that matters in practice. If your vehicle qualifies for the green sticker, get it before you travel.

How to apply

The simplest route before you travel is to apply online through a German city portal. Berlin.de tends to be the most straightforward option for applicants with a foreign-registered vehicle. Alternatively, you can get the sticker in person at any TUV or DEKRA testing station once you are in Germany; take your V5C with you. The sticker costs EUR 6 through an official channel. Commercial resellers typically charge EUR 15 to EUR 20 for the same thing. Once it is on your windscreen, it is valid for the life of the vehicle on that plate.

The camera-and-database countries.

Belgium (Brussels, Antwerp, Ghent)

Belgium takes a different approach. There is no sticker to buy or display. Instead, ANPR cameras read every number plate entering the zone and check it against a national database automatically. If your UK-registered motorhome is not on that database, you will be fined, even if your vehicle easily meets the required standard. For Brussels, register your plate free at lez.brussels. For Antwerp and Ghent, register free at sna.be; one registration covers both cities. If your vehicle does not meet the emission standard, you can buy a Day Pass for around EUR 35. Brussels limits these to 8 passes per vehicle per year.

Netherlands (Milieuzone)

No sticker needed. Dutch cities including Amsterdam, Rotterdam, The Hague, Utrecht and Arnhem check your Euro standard and first-registration date automatically. Most zones now require a minimum of Euro 4 or Euro 5 for diesel motorhomes. Amsterdam has added Zero Emission zones in the centre, but at the time of writing these only affect commercial vehicles. Most UK motorhomes are registered as M1 on the V5C, so the car rules apply; if yours is N1, the stricter HGV rules apply instead. If your vehicle is borderline on age, give Amsterdam's central areas a miss and use a P+R site outside the ring road.

Italy (ZTL and Area B Milan)

Italy does things slightly differently. ZTL, Zona Traffico Limitato, schemes are mainly about access rather than emissions, though the two often overlap. Milan, Rome, Florence, Bologna, Naples and most other large cities all have them. Milan Area B covers most of the city: Euro 4 and Euro 5 diesels are largely banned unless a Move-In black box is fitted, which is rarely worth arranging for a single visit. Milan Area C is the central congestion zone, 7.50 EUR per day paid in advance. In Florence, Rome and Bologna, ANPR cameras log every entry point, and fines of 80 to 300 EUR per camera triggered can stack up. For most Italian cities the straightforward answer is to park outside the restricted area and walk or use public transport; see our Italy country guide for park-and-ride locations.

Spain (Barcelona and Madrid ZBE)

Spain uses ZBE, Zona de Bajas Emisiones, schemes in Barcelona, Madrid and a growing number of other cities. Spanish vehicles display a Distintivo Ambiental sticker, but that sticker is not available to foreign-plated motorhomes, so you register online instead. For Barcelona, register at the AMB website before you travel; Euro 4 petrol or Euro 4/5 diesel motorhomes can enter freely, and if your vehicle does not meet those standards you can apply for a 24-hour permit, up to a maximum of 10 per year. For Madrid, the Distrito Centro is restricted to residents and higher-emission vehicles cannot enter the broader municipality at all; park outside the M-30 ring road and take the metro in. Registration fees run to around 5 to 10 EUR depending on the city.

The easier countries, and the mistakes.

Austria, Sweden and Norway are easier going for most UK motorhome owners.

• Austria. Emission stickers, Abgasplakette, only apply to N-category commercial vehicles. If your motorhome is registered M1, you are exempt. If it is registered N2 or N3 and weighs over 3.5 tonnes, you need one.
• Sweden. The Stockholm and Gothenburg LEZs target heavy HGVs and buses. Passenger-class motorhomes are clear of the emission bans, though congestion charges still apply.
• Norway. No stickers required. AutoPASS tolls include an environmental surcharge, so diesel vehicles typically pay a little more. Oslo issues short-notice diesel bans on high-pollution days; check before you drive in.

The common mistakes

The Euro 6 trap: a newer, cleaner diesel does not get you automatic entry anywhere. You still need to display the correct French or German sticker, or register on the Belgian or Spanish portal, regardless of what Euro standard your engine meets. Third-party sticker sellers: search "Crit'Air sticker" and the top results are usually resellers charging 15 to 30 EUR for a sticker that costs 4.61 EUR direct. And weight and registration class: motorhomes over 3.5 tonnes sometimes fall under stricter commercial-vehicle rules, so check whether the V5C says M1 or N1, N2 or N3.
