Air quality in Tres Cantos remains within legal and European parameters, according to a study by the Community of Madrid conducted between January and February 2026.

Atmospheric pollution levels in Tres Cantos are below the limits set by national and European regulations. This is the conclusion of a specific measurement campaign carried out by the General Directorate of Energy Transition and Circular Economy of the Community of Madrid.
The study, conducted between January 15 and February 22, 2026, analyzed the main atmospheric pollutants using two mobile units from the regional Air Quality Network. The results indicate that recorded levels remain well below legal limits, posing no risk to the population's health.
The two mobile stations, located next to the Local Police Station and in the parking lot of the sports facilities of the Colegio Ciudad de Nejapa, evaluated pollutant behavior during the winter. The report concludes that no limit values for PM10 and PM2.5 particles, nitrogen dioxide (NO₂), ozone (O₃), and sulfur dioxide (SO₂) were exceeded.
Furthermore, concentrations of carbon monoxide, benzene, and hydrocarbons registered reduced levels, far from the health alert or prevention thresholds. The data depict a scenario of low atmospheric pollution in the municipality.
The assessment by the Community of Madrid indicates that levels detected in Tres Cantos are similar to or lower than those in other municipalities such as Colmenar Viejo, Alcobendas, Algete, or Collado Villalba. These readings are consistent with the typical behavior of a residential urban environment with low pollution levels.
The Air Quality Index was classified as 'good' or 'reasonably good' for 100% of the analyzed time, with no regular, unfavorable, or very unfavorable values recorded.
The influence of road traffic on air quality is limited. Although slight increases in pollutants were detected during peak mobility hours, especially near the Local Police Station, concentrations remained below legal limits at all times.
The General Directorate of Energy Transition and Circular Economy considers the atmospheric situation in Tres Cantos to be compatible with the air quality standards required by current legislation, thus extraordinary corrective measures are not deemed necessary.
