Low-emission zones by country

A low-emission zone is an area a city closes to vehicles below a set emission standard. The French government counts more than 230 of them in Europe. They are created by cities and regions, not by the EU, so the name, the boundary, the hours and the emission threshold change from one town to the next — and so does what you have to do before you drive in.

Four things a zone can ask of you

The first is a windscreen sticker. Germany requires the Umweltplakette under the 35th Federal Immission Control Ordinance, France requires a Crit'Air certificate under the General Code of Territorial Collectivities, and Spain issues the DGT environmental badge. In Germany and France the requirement applies to foreign plates exactly as it does to local ones.

The second is registration. Belgium requires every foreign-registered vehicle except Dutch ones to be entered in a register before it enters a low-emission zone; registration is free, but Brussels and Flanders run separate systems. Denmark abolished its physical sticker on 1 July 2020 and replaced it with an online registration that older diesel vehicles must complete on the day they drive into one of the five zones.

The third is nothing at all in advance, because the check runs against the number plate. That is how the Netherlands, Sweden, Poland, Italy and Portugal work. Your vehicle either meets the emission class or it does not, and a camera decides.

The fourth is money. England charges non-compliant vehicles to enter a Clean Air Zone and London to enter the ULEZ. Scotland is different again: its four zones do not sell entry, they ban non-compliant vehicles and issue penalty charges.

A sticker from one country is never valid in another

There is no EU-wide eco-sticker and no mutual recognition. A German green sticker does nothing in France, and a Crit'Air certificate does nothing in Germany. The European Parliament has been asked about harmonising the schemes repeatedly and they remain national.

Spain shows what this means in practice. The DGT badge is issued against Spanish vehicle records, so the agency's own advice to foreign drivers is to check each municipality's rules and whether their vehicle's home classification maps onto the Spanish labels at all.

Buy only from the official site

Both the French and the Dutch authorities publish explicit warnings about this. Bison Futé tells drivers that the Crit'Air certificate is sold only at certificat-air.gouv.fr and to beware of intermediaries and fraudulent sites. The Dutch RDW warns that it is the only body that grants zero-emission-zone exemptions and that any site charging a fee for one is defrauding you.

Every country row in the table below links to the authority that actually runs the scheme, so you can go straight to the source rather than to a reseller.

How a zone finds a foreign car

Enforcement is almost entirely automatic number-plate recognition. The catch is that national vehicle registers hold national plates: Poland checks against CEPiK, the United Kingdom's official zone checkers state plainly that they cannot check a vehicle registered outside the UK. That gap is exactly why Belgium and Denmark make foreign vehicles register in advance.

It no longer means the fine is unenforceable. Directive (EU) 2024/3237 added "failing to respect vehicle-access restrictions" to the list of offences that EU countries exchange driver data for, so entering a zone you were not entitled to enter is now explicitly cross-border business.

Why this is slowly getting easier

Regulation (EU) 2018/1724 obliges authorities to publish access rules and emission-sticker information online. Commission Delegated Regulation (EU) 2022/670 goes further and requires Member States to supply machine-readable data about these zones through their National Access Points, applicable from January 2025.

Until that data is complete everywhere, the municipal page remains the only authoritative answer for a specific street on a specific day.
