The DGT Environmental Sticker and Low-Emission Zones in Spain

Which distintivo ambiental does your car get, where do you actually need it, and what about a UK-plated car? A plain-English guide to Spain's eco-sticker and its growing Low-Emission Zones.

Spain sorts cars into four environmental classes — 0, ECO, C and B — with a coloured distintivo ambiental (DGT environmental sticker) for each, and nothing at all for the most polluting. The sticker matters more every year, because Spain is rolling out Low-Emission Zones (Zonas de Bajas Emisiones, ZBE) in town after town, and the dirtiest cars are increasingly shut out. This guide explains which sticker your car qualifies for, where you genuinely need one, how to buy it, and the rules for foreign and UK-plated vehicles.

The eco-sticker at a glance

  • Four categories: 0 (blue), ECO (green/blue), C (green) and B (yellow) — the oldest cars get no label at all.
  • It's about emissions and age, not where you bought the car — petrol from 2006 and diesel from 2014 typically get the C label.
  • Where you need it: to drive in a Low-Emission Zone. Over 50 Spanish cities already enforce one and the number is heading toward ~150, including Madrid, Barcelona, Valencia, Alicante and Benidorm.
  • Where to buy it: any main Correos post office for about €5, or an authorised workshop or gestor. Check your category first with your plate on the DGT website.
  • UK-plated cars can't get a DGT sticker — but must still comply, and some cities require foreign vehicles to register before entering a ZBE.

What is the DGT environmental sticker?

The distintivo ambiental is a small coloured disc issued by Spain's traffic authority, the DGT (Dirección General de Tráfico), that classifies a vehicle by how much it pollutes. It has been around since 2016 and is the key that opens — or closes — Spain's Low-Emission Zones. The cleaner your car, the higher its class and the fewer restrictions it faces. The label is tied to the vehicle on the DGT register, so it stays with the car, not the owner.

Which sticker does your car get?

Classification is based on the fuel type and the date or emissions standard of the vehicle. The long-standing bands are:

LabelRoughly who gets it
0 (Cero, blue)Pure electric, hydrogen fuel-cell, and plug-in hybrids with a decent electric-only range
ECO (green & blue)Standard (non-plug-in) hybrids, shorter-range plug-in hybrids, and CNG/LPG (gas) cars that also meet the C standard
C (green)Petrol registered from January 2006 and diesel from 2014 (modern Euro standards)
B (yellow)Petrol registered from January 2000 and diesel from 2006
No labelPetrol before 2000 and diesel before 2006 — the most restricted

The simplest way to be sure is to enter your registration on the DGT's official checker — it tells you the exact category for your car. Don't assume from the year alone, as diesels in particular sit a step behind petrol.

A reform is coming — check before you assume

The DGT has announced a reform of the sticker criteria that tightens the bands — for example reserving the 0 label for plug-in hybrids with a longer electric range, and requiring newer Euro standards for the ECO and C classes. If it takes effect as announced, some vehicles would be reclassified (an "ECO" car could drop to "C", for instance). Because the detail and timing can change, always confirm your car's current category on the DGT tool rather than relying on an older classification.

Low-Emission Zones (ZBE): where the sticker really matters

Under Spain's climate-change law (Ley 7/2021), every municipality with more than 50,000 inhabitants (and the larger island towns) must establish a Zona de Bajas Emisiones. Dozens already enforce one and the total is climbing toward around 150 — not just Madrid and Barcelona but, close to home for many expats, Valencia, Alicante and Benidorm.

Inside a ZBE:

Each town sets its own boundaries and timetable, so check the local ayuntamiento for the zone you drive in. Penalties for entering a ZBE without the right to are typically around €200 (often halved to about €100 if paid promptly).

This is one of the fastest-moving areas of Spanish driving law. New zones and tighter rules arrive every year, so what is waved through today may be restricted next year — keep an eye on your own town's scheme.

Where and how to buy your sticker

You will need the vehicle's documentation (permiso de circulación / registration). First, check your category with your plate on the DGT's distintivo ambiental tool so you order the right one. Then simply stick it inside the windscreen, bottom corner.

Do you have to display it? Carrying the sticker isn't a blanket national obligation in itself, but you need the right category to enter a Low-Emission Zone — and displaying it makes enforcement (and your life) simpler. For €5, there's little reason not to.

Foreign and UK-plated cars

If your car is still on UK (or other foreign) plates, there's a catch: the DGT sticker is only issued to vehicles on the Spanish register, so you can't buy one. That does not mean you escape the rules — a foreign-plated car must meet the same Low-Emission-Zone standards as a Spanish one. In practice:

Does the sticker affect my car insurance?

Not directly — your car insurance in Spain is priced on the usual factors, not your environmental label. But the two sit together under "driving legally in Spain": the sticker keeps you out of trouble in Low-Emission Zones, just as valid insurance, a current ITV and (from 2026) the V16 beacon keep you road-legal. If you are switching from a UK car to a Spanish one, we sort the insurance side the moment the car is registered — and for a full picture of what's compulsory, see which insurance is required by law in Spain.

Frequently asked questions

There are four: 0 (blue) for electric, hydrogen and longer-range plug-in hybrids; ECO (green and blue) for hybrids, shorter-range plug-ins and gas cars; C (green) for petrol from 2006 and diesel from 2014; and B (yellow) for petrol from 2000 and diesel from 2006. The oldest cars (petrol pre-2000, diesel pre-2006) get no label.

Enter your registration on the DGT's official distintivo ambiental checker — it returns the exact category. Don't judge by the year alone, because diesel cars sit a step behind petrol of the same age, and a planned reform may reclassify some vehicles.

Any main Correos post office issues it over the counter for about €5, and authorised workshops, gestorías and some ITV stations also supply it. Bring the vehicle's registration document, and check your category first so you order the right label.

Carrying it isn't a blanket national requirement on its own, but you need the right category to enter a Low-Emission Zone, and displaying it makes enforcement straightforward. Given it costs around €5, most drivers simply get it and stick it in the windscreen.

Under Ley 7/2021, every town over 50,000 inhabitants must have one. Over 50 already enforce a ZBE and the number is rising toward around 150 — including Madrid, Barcelona, Valencia, Alicante and Benidorm. Each sets its own boundary and rules, so check the local ayuntamiento.

No — the sticker is only issued to vehicles on the Spanish register. A foreign-plated car must still meet the same Low-Emission-Zone rules, and cities like Madrid and Barcelona require foreign vehicles to register their emissions category before entering. If you live in Spain, the answer is to matriculate the car onto Spanish plates.

Typically around €200, often reduced to about €100 if paid promptly. Automatic enforcement on foreign plates has been limited by technical hurdles, but police can stop and fine you on the spot, and cross-border collection of fines (including to the UK) is increasing.

No — your premium is based on the usual factors, not your environmental label. The sticker is about access to Low-Emission Zones, not insurance. That said, both are part of driving legally in Spain, and as your agent we can sort the cover whenever you register or import a car. Call 966 461 625.
