Spain's low-emission zones and the DGT's environmental label
By Covered Abroad Research Desk · Last verified July 2026
The label, per the DGT
The DGT defines it plainly: el distintivo ambiental es una manera de clasificar los vehículos en función de su eficiencia energética, teniendo en cuenta el impacto medioambiental de los mismos. Four classes descend from cleanest — CERO (blue), ECO, C and B — assigned by fuel type, Euro standard and registration date, with the DGT's page carrying the per-class criteria, the label's validity rules, and where to buy it (Correos among the outlets).

Check any plate before you buy a car
The mover's power tool on the DGT page: puedes consultar si un vehículo cumple los requisitos que dan derecho a obtener algún tipo de distintivo ambiental conociendo la matrícula — a plate-number lookup that works even if the vehicle isn't yours. Buying a used car in Spain? Run the plate first: a B-label (or no-label) car faces a shrinking map as city ZBEs tighten, and that belongs in the price negotiation.

60-second check
Not sure the policy you have meets your destination's written rule? Run it through the policy check now, before you build the rest of the file around it.
Check my policyThe zones are municipal — the label is national
The DGT issues the label; each city writes its own ZBE rules on top — which classes enter, when, and with what exceptions. Madrid and Barcelona run the flagship zones and other cities keep joining, so the honest advice is a moving-target one: check the destination city's current ZBE ordinance rather than a cached blog table. For imported cars, the label question lands right after the import process — and a foreign-plated car's access to a Spanish ZBE follows the city's rules for foreign registrations.
