ECO label in 2026: which cars really get it

The ECO label is not granted by the hybrid or gas engine alone: the car must also meet the C-label requirements. That is why some LPG cars stay on a B.

How the answer was reached, step by step
  1. Self-charging petrol hybrid (HEV) technology: ECO label.
  2. Visitor with an out-of-town plate: free access to 33 of the 38 city zones on this site as of 17 October 2026.

Estimate based on the byelaws and DGT criteria checked on 15 October 2026. The byelaw in force and, for the label, the DGT number-plate lookup have the final word. How we calculate

The DGT’s ECO label goes to cars and light commercial vehicles registered as plug-in hybrids with under 40 km of range, self-charging hybrids (HEV) and vehicles running on compressed or liquefied natural gas (CNG, LNG) or liquefied petroleum gas (LPG). In every case they must also meet the C-label criteria: Euro 4, 5 or 6 for a petrol engine and Euro 6 for a diesel. For vehicles with more than 8 seats and goods vehicles Euro VI is required whatever the fuel, and motorbikes only need to be hybrid. With the ECO label you can drive freely into 33 of the 38 cities with zones on this site and cross Madrid’s Centro district without having to park; the exceptions, A Coruña, Alicante, Jerez de la Frontera, León and Salamanca, are permit-only historic centres where no label is enough without authorisation. Several councils give road-tax relief: Madrid 75% for six years for ECO cars registered from 2026, Barcelona 50% for five years for petrol ones emitting up to 120 g/km of CO2.

Two conditions, not one

The most common mistake with the ECO label is to think the engine type is enough. The DGT puts it plainly: they “must meet the criteria of the C label”. A modern self-charging hybrid always does; an old car adapted to gas does not. That is why some LPG cars carry a B, and why converting a very old car to gas is not a route to the ECO.

Where it makes a difference

In almost every zone a C is enough today. The ECO adds two things: free passage through Madrid’s Centro district, where an out-of-town C may only go to a car park, and long-term security, because the Palma, Valladolid and Vitoria-Gasteiz timetables keep it free in 2030. On tax, relief varies a lot from city to city.

What drivers ask

My 2004 car was converted to LPG: does it get the ECO label?

Not because of the conversion. The DGT requires gas vehicles to also meet the C criteria, and a 2004 petrol car is usually Euro 3, which means a B. That is why the tool returns a B for an old LPG car. A factory LPG car, or one converted with a Euro 4 or later engine, does get the ECO.

Does a diesel hybrid always get the ECO label?

No. Annex II of the General Vehicle Regulation requires a hybrid to meet the C criteria “in all cases”, which for a diesel means Euro 6. A Euro 5 diesel hybrid keeps the B of its engine. By date, ECO is certain for a diesel hybrid registered from September 2015; between September 2014 and August 2015 it depends on its type approval.

Do mild hybrids get the ECO label?

It depends on how the DGT records them, as self-charging hybrids or not. Many 48-volt mild hybrids are listed as HEV and get the ECO, but not all. The safe way to know is the number-plate lookup on the DGT online office, which returns the label the vehicle is entitled to.

Is a plug-in hybrid with 45 km of range an ECO car?

No: with 40 km or more of pure-electric range, the DGT gives it the zero-emissions label, not ECO. ECO is for plug-ins with under 40 km. The range that counts is the approved figure on the vehicle register, not what you achieve in daily driving.
