Spain's DGT Environmental Label Explained: The Complete Guide to 0, ECO, C and B

What the environmental label actually is

The distintivo ambiental is a classification the Dirección General de Tráfico assigns to every vehicle registered in Spain based on three things only: fuel type, the Euro emissions standard it meets, and its registration date. It is not a sticker you request separately, and it is not something you apply for. The DGT calculates it automatically from the data in the national vehicle registry the moment a car is registered, including an imported one.

There are four categories, from best to worst environmental standing: 0 (blue), ECO (blue and green), C (green) and B (yellow). Vehicles that do not meet even the minimum requirements for label B get no sticker at all.

Label 0 (Zero Emissions)

According to the DGT, label 0 covers battery electric vehicles (BEV), range-extended electric vehicles (REEV), plug-in hybrids (PHEV) with a minimum homologated electric-only range of 40 km, and hydrogen fuel-cell vehicles.

• Pure electric vehicles (BEV): no additional conditions.
• Plug-in hybrids (PHEV) with 40 km or more of homologated electric-only range.
• Hydrogen fuel-cell vehicles.
• Label 0 is the only sticker with guaranteed access to every Low Emission Zone in Spain.

Label ECO

Label ECO groups vehicles that cut emissions but do not reach label 0: plug-in hybrids (PHEV) with less than 40 km of electric range, non-plug-in hybrids (HEV), and vehicles running on compressed or liquefied natural gas (CNG/LNG) or liquefied petroleum gas (LPG, autogas). All of them must also meet the Euro standard and registration-date criteria required for label C.

Label C (green)

Label C applies to petrol cars and light vans meeting Euro 4, 5 or 6 and registered from January 2006 onward, and to diesel vehicles meeting Euro 6 and registered from September 2015 onward. This is the detail people get wrong most often: a diesel from 2016 with Euro 6 gets label C, but a diesel from 2014, even though it looks nearly as new, stays on label B because it misses both the Euro standard and the date cutoff.

Label B (yellow)

Label B applies to petrol cars and light vans registered from 1 January 2001, and to diesel vehicles registered from 2006 that do not reach Euro 6 — in practice, most diesels registered between 2006 and September 2015 land here.

Vehicles with no label at all

Petrol cars registered before 2001 and diesel cars registered before 2006 receive no sticker whatsoever. They are the most restricted category inside Low Emission Zones and, in most Spanish cities, cannot enter the regulated urban core except under specific, limited authorisations.

The label is not about whether your car 'looks new.' It comes down to three exact data points: fuel, Euro standard, and registration date.
