Low Emission Zones have gone from being an idea to becoming a regulatory reality that affects the daily life of many Spanish cities, with clear rules on access, circulation and parking according to the environmental impact of each vehicle; this article breaks down, in detail and in direct language, how these zones are structured and what all this means for citizens and for the affected economic sectors. integrating regulations, real-world examples, and municipal procedures.
Beyond the headline, the key lies in understanding the legal framework, the practical scope of the restrictions, and the mechanisms for control and citizen support; you will find an overview of the standard ordinances used by city councils to regulate Low Emission Zones, a specific focus on Zaragoza's ordinance, and a review of what cities like Malaga, Salamanca, and Bilbao are already implementing. including calendars, streets, exemptions and sanctions system.
Legal framework and objectives of Low Emission Zones
The basis of it all starts in the Spanish Constitution, which recognizes the right to a suitable environment (art. 45) and obliges public authorities to protect it, while other rights such as health and freedom of movement coexist; from this combination arises a balance that allows traffic to be restricted for environmental reasons, always within the limits of legality and proportionality.
At the European level, the main references are Directive 2008/50/EC on air quality and Directive 2004/107/EC on certain heavy metals and PAHs; in addition, Directive 2016/2284 sets state obligations for emission reductions and planning, marking the supranational context that pushes cities to act.
In Spain, Law 34/2007 on air quality and protection of the atmosphere empowers local entities to adopt plans and programs with traffic restrictions where appropriate; Law 7/1985 on the Bases of Local Government assigns municipal powers in urban environment, traffic and mobility, making it clear that the local level plays a leading role in planning and control.
Law 33/2011, the General Law on Public Health, also mandates that public authorities take action against environmental risks to protect health; the Consolidated Text of the Traffic Law (Royal Legislative Decree 6/2015) empowers municipalities to restrict traffic and close roads for environmental reasons, always on an exceptional and justified basis. which translates into concrete and verifiable powers.
Law 7/2021 on climate change mandates the implementation of Low Emission Zones (LEZs) in municipalities with more than 50.000 inhabitants (and those with more than 20.000 if they exceed pollutant limit values), requiring their incorporation into the Sustainable Urban Mobility Plan (SUMP) and local action plansRoyal Decree 1052/2022 specifies how these areas should be delimited and regulated, referring the implementation and details to the municipal ordinances.
The principles of Article 129 of Law 39/2015 are applied in the processing and drafting of ordinances: necessity, effectiveness, proportionality, legal certainty, transparency and efficiency; this implies setting measurable objectives, coherence with planning and avoiding unnecessary burdens. with public information periods and information campaigns.
Model municipal ordinance: essential content and operation
A Low Emission Zone (LEZ) ordinance defines what the zone is, its perimeter, when it is in effect, who it affects, what intervention measures are applied, how it is signposted, what vehicles can pass through and why, in addition to regulating registration, control, data, parking, urban goods delivery (DUM), customer service and sanctions, completing a comprehensive management framework.
Purpose and Scope
These municipal regulations create and manage continuous (or intermittent) Low Emission Zones (LEZs) in order to improve air quality and mitigate greenhouse gases; they affect all vehicles circulating within the municipality when they enter the delimited perimeter, with possible temporary exceptions consistent with the technical project. and always according to the DGT's environmental classification.
The operational definition includes the obligation to display the environmental badge when one exists (according to the General Vehicle Regulations), official signage, and alignment with municipal plans such as the SUMP or other instruments. avoiding contradictions and double rules.
Local powers and regulatory basis
The municipality regulates the use of urban roads by ordinance, and may restrict access, traffic and parking for environmental and air quality reasons; this power is based on various state and regional regulations, and is materialized in plenary and government agreements to delimit the area or modify annexes. with participation and advertising procedures.
Technical project and periodic reviews
The technical project describes the type of zone, surface area, population, responsible bodies, perimeter, pollution diagnosis, measures and schedule, control system and consistency with planning; in addition, a review is set at three years and then at least every four, to evaluate results and adjust measures.
Phased implementation and consistency with planning
The implementation is usually structured in stages: information periods, monitoring without sanctions, opening of the register and, finally, automated control with sanctions; this gradual approach allows for citizen and business adaptation. at the same time as aligning timelines with mobility and air quality plans.
Signage and temporary conditions
The entrances and exits of the Low Emission Zone (LEZ) are signposted with the official DGT logo, indicating whether the zone is continuous or has specific hours, as well as the environmental categories with prohibited access and the authorized exceptions; additional information may be displayed on a lower panel. to give the driver certainty at the critical decision point.
Intervention measures and pollution episodes
The main intervention is the restriction of access, circulation and parking for the most polluting vehicles, allowing or limiting them according to environmental badge and for reasons of public interest; when there is a pollution episode, the specific municipal protocol is activated with extraordinary measures. coordinated with urban mobility regulations.
Authorized vehicles and municipal registry
Generally, cycles, bicycles and personal mobility vehicles (PMVs), as well as cars and vans with B, C, ECO and 0 labels, are allowed free entry, in accordance with the provisions of the ordinance's annex; for other cases, a municipal register is established that grants temporary and verifiable authorizations. limited by dates, days or hours as the case may be.
Data control and protection system
Access is controlled with automated systems linked to municipal technological platforms; cameras and license plate readers are used without capturing occupants, with a specific resolution that orders their use, and complying with data protection legislation. including a margin of error departure of at least 15 minutes without penalty.
Parking and DUM
Within the perimeter there may be resident parking zones and regulated rotation areas, with rates adapted to the environmental label and corresponding tax ordinance; parking outside of designated areas is prohibited. and the regulatory reference is the Regulation of the Regulated Parking Service.
Urban freight distribution relies on specific loading and unloading zones—permanent or by time slot—and prioritizes, where appropriate, last-mile delivery with non-polluting vehicles; vehicles classified for urban freight distribution (trucks, vans, mixed-use vehicles, two-seater passenger car derivatives, bicycles and personal mobility vehicles) and professional drivers are included. with time limits per operation.
Awareness, citizen services and principles of good regulation
The ordinances include information campaigns, public information periods of at least 30 days, and in-person, telephone, and online channels for inquiries and procedures; the municipal website centralizes everything. promoting close and transparent management.
In terms of urban design and road safety, the importance of pedestrian crossings perpendicular to the sidewalk is emphasized to better guide people with visual disabilities, reserving the diagonal crossing for necessary cases and tactilely marking its limits. a technical detail that enhances accessibility in ZBE environments.
Sanctions regime
Infringements for disobeying restrictions derived from Low Emission Zones or pollution episodes are classified as serious in article 76.3 (z3) of the Traffic Law; in addition, failure to display the environmental sticker when required is considered a minor infringement. and everything is processed in accordance with state traffic legislation.
Until the full deployment of electronic monitoring, surveillance may fall to the Local Police, who will issue informational reports during the educational phase; the usual entry into force occurs fifteen days after official publication. and the modification of annexes may be approved by government agreement except for nuclear changes.
Zaragoza: delimitation, schedule and operational details (Annex 1)

Malaga: definition, rules, perimeter and access schedule
The Malaga Low Emission Zone (LEZ) covers approximately 404,03 hectares and aims to improve air and noise quality, promote modal shift, encourage less polluting vehicles, digitize mobility, and increase transport efficiency; control relies on traffic management and license plate recognition connected to the municipal platform with DGT data and census records. no obligation to carry the physical sticker while driving.
The regulatory framework includes Law 7/2021 and Royal Decree 1052/2022; in addition, the City Council approved its Sustainable Urban Mobility Plan (SUMP) in 2021 and promoted projects with Next Generation funds (requesting €26.030.700 for eight projects, of which €5.161.420 was for the Low Emission Zone), tendering the comprehensive control system in 2022, awarded to a joint venture (Tecnologías Viales Aplicadas TEVA and Tevaseñal) for €3.134.311 and a one-year execution period, with a subsequent extension. demonstrating a substantial technological investment.
The perimeter of the enclosure is based on a list of main streets: from Paseo Marítimo Antonio Machado, Ingeniero José María Garnica, Explanada de la Estación, Plaza de la Solidaridad, Avenida de las Américas, Avenida de la Aurora, Jardines de Picasso, Avenida de Andalucía, Compositor Lehmberg Ruiz, Hilera, Santa Elena, Honduras, Arango, Martínez Maldonado, Avenida de Barcelona, Plaza del Hospital Civil, Doctor Gálvez Ginachero, Mazarredo, Avenida del Arroyo de los Ángeles, Paseo de Martiricos, Huerto de los Claveles, Marqués de Cádiz, Juan del Encina, Empecinado, Plaza Capuchinos, Alameda de Capuchinos, Plaza Olletas, Toquero, Obispo González García, Amargura, Ferrándiz, Paseo Salvador Rueda, Rafael Pérez Estrada and Paseo Marítimo Pablo Ruiz Picasso, closing a wide and strategic ring.
Implementation schedule by environmental labels: first year, ZERO, ECO, C, B and also vehicles without a label can circulate; second year, ZERO, ECO and C, in addition to B and those without a label domiciled in Malaga; from the third year onwards, ZERO, ECO and C, plus B domiciled in Malaga and without a label domiciled in Malaga, with a progressive and territorialized approach.
Other cases of free access: regular public transport, taxi and VTC, historic vehicles (according to RD 1247/1995) and trucks; vans: during the first four years they can circulate ZERO, ECO, C, B and without a sticker; from the fifth year onwards, ZERO/ECO/C/B vans registered in Malaga and without a sticker registered in Malaga, with a specific approach to delivery and services.
Access subject to prior communication/automated validation: public and private healthcare, Security Forces, municipal services, and private services of special need (private security, drain cleaning, funeral homes, cash transport and similar), allowing traceability in justified entries.
DGT classification (consult on the DGT website): 0 emissions (BEV, REEV, PHEV ≥40 km and fuel cell), ECO (PHEV <40 km, HEV, CNG/LNG/LPG) subject to criteria of C, C (recent Euros: petrol since 2006 and diesel since 2015; heavy since 2014) and B (gasoline since 2001, diesel since 2006; heavy since 2006), common parameter that structures access.
Salamanca: long phases, two zones and automated control
The Salamanca ordinance came into force in June 2024, although the restrictions will not begin until 2029; residents will not be affected by access limitations under any circumstances, so they will not be forced to change their vehicle. protecting the continuity of neighborhood life.
There will be two Low Emission Zones (LEZs): Zone 1, called the 'Pedestrian Zone' —with a perimeter that includes Puerta de Zamora, Avenida de Mirat, Plaza de España, Gran Vía, Calle Caldereros, Plaza de Colón, Calle San Pablo, Puerta de San Pablo, Paseo del Rector Esperabé, Paseo de San Gregorio, Vaguada de la Palma, Cuesta de San Blas, Calle Fonseca, Calle Ramón y Cajal, Paseo de Carmelitas, Plaza de la Fuente, Calle Arriba, Calle Campo de San Francisco, Calle de Abajo, Plaza de la Vera Cruz Verdadera, Calle Sorias, Calle Peña Primera, Plaza de los Bandos, Calle Santa Teresa, Calle Condes de Crespo Rascón, Calle Isabeles, Reyes Católicos and Paseo de Carmelitas— plus an outer zone, defining a well-known urban grid.
Access schedule: until 2029, no restrictions by sticker; from 2029 until 31/12/2033, access prohibited to vehicles with sticker A; between 01/01/2034 and 31/12/2038, A and B will not be allowed; from 01/01/2039, only Zero Emissions and ECO vehicles. with a very gradual and predictable transition.
Access control will be carried out with license plate readers in the Pedestrian Zone, with a six-month adaptation period during which no penalties will be issued; for specific needs (medical centers, hotels, parking lots, etc.), there is a digital authorization platform that grants temporary permits. simplifying procedures and avoiding travel.
Exemptions and allowable exceptions, regardless of label, with prior temporary authorization where applicable: residents, bicycles and personal mobility vehicles (PMVs), ECO and Zero Emission vehicles, shared vehicles, people with reduced mobility (PRM), essential public services, those registered in the Low Emission Zone (LEZ), holders of a garage space within the perimeter, vehicles to provide services, access to public parking, pick-up and drop-off of PRM, medical appointments, schools and specific occupations; those who reside or have a garage within the Pedestrian Zone and pay the IVTM in Salamanca will be automatically registered. avoiding unnecessary administrative burdens.
Bilbao: Low Emission Zone active and rules by environmental badge
Since June 15, 2024, Bilbao's Low Emission Zone (LEZ) has been in effect, aligned with the Climate Change Law and focused on improving air quality, reducing greenhouse gases and mitigating noise; vehicles with 0, ECO and C emissions can freely access it, while B and A vehicles can only do so in specific cases. applying a clear and easily understandable scheme.
Signage, control, data and citizen services
Local councils mark access points and the end of the zone with official pictograms, detailing whether the Low Emission Zone (LEZ) is continuous or in strips and which markings restrict access; exceptions permitted by authorization may be illustrated on a lower panel. for immediate reading while driving.
Automated control relies on cameras and ANPR systems integrated with official databases, avoiding capturing images of occupants; there is a margin of error of at least 15 minutes, and the installation/use of devices requires a resolution from the traffic authority and strict compliance with data protection regulations. balancing legal certainty and efficiency.
The channels of communication with citizens include in-person, telephone and online services, with all information published on the municipal website; in addition, there are information campaigns and public information periods for the technical project and its revisions. strengthening transparency and participation.
In parking, Low Emission Zones (LEZs) integrate their rules with the existing regulated service, differentiating between residents and short-term parking, and incorporating rates modulated by the environmental label; in Urban Mobility Zones (UMDs), reservations are defined with schedules and maximum times per operation, prioritizing, where appropriate, less polluting vehicles in the last mile. to reconcile economic activity and environmental objectives.
The types of registration authorizations include PRM (People with Reduced Mobility), residents, garages, businesses, essential service fleets, verified foreign registration, healthcare due to illness, hotels and connected parking facilities, special cases (cranes, cement mixers, driving schools, etc.) and limited number of sporadic accesses; these authorizations have deadlines, renewals and temporary conditions. which must be consulted and requested in advance.
The penalty system adheres to the Traffic Law: violating a Low Emission Zone restriction or a pollution episode protocol is a serious offense, while failing to display the sticker when required is a minor offense; before full telematic control there are usually educational and warning phases without penalty. to facilitate the change of habits.
As a key point for professionals and residents, choosing the right route, checking the DGT sticker, checking if authorization is needed, and monitoring loading/unloading and parking times prevents incidents; information is available on municipal websites and customer service channels. and is updated with each revision of the technical project..
This entire regulatory and operational framework—from the Constitution to municipal annexes, including European directives, state laws, and Royal Decree 1052/2022—aims to reduce emissions and protect health without paralyzing urban activity; by establishing perimeters, schedules, exceptions, and control systems, It is much easier to move around smoothly and comply with the ordinance..
