Students from a secondary school in Barcelona’s Eixample district are set to block a major thoroughfare on Monday to protest against persistent air pollution. This highlights a growing tension between positive city-wide environmental data and the daily reality for residents in high-traffic zones.

The demonstration comes as the city reports its best-ever air quality figures for 2025, with historic lows in harmful particulate matter and nitrogen dioxide (NO2). Data from monitoring stations across Barcelona shows a decline of at least 4% in key pollutants. Furthermore, figures from the Agència de Salut Pública de Barcelona (ASPB) indicate that mortality attributable to air pollution has fallen significantly. Between 2020 and 2024, there was a 32% reduction compared to the 2018-2019 period, equating to 600 avoided deaths. Preliminary estimates for 2025 suggest this could rise to a 40-45% reduction compared to pre-pandemic levels, potentially saving 800 lives.

Persistent Pollution Hotspots

Despite these encouraging trends, pollution remains concentrated in several urban hotspots. For example, traffic-monitoring stations in the densely populated Eixample district recorded an annual average of 29 micrograms of NO2 per cubic metre (µg/m³) in 2025, down from 33 µg/m³ in 2024. In the Gràcia and Sant Gervasi districts, the level was 25 µg/m³, a slight improvement on the previous year’s 27 µg/m³.

These figures, while improving, remain well above the guidelines set by the World Health Organization (WHO), which recommends an annual average NO2 concentration of just 10 µg/m³. This discrepancy has prompted action from students and parents at the Institut Angeleta Ferrer, located on Carrer de la Marina in the heart of Eixample.

On Monday, 9th February, students plan to block the street outside their school from 12:15h. This marks the second consecutive school year they have organised such a protest, aiming to raise awareness of the health risks they face daily.

Fighting for the Right to Clean Air

Organising parents stated that the air quality around the school fails to meet most international health standards. “Our centre does not meet most of the values recommended by the World Health Organization,” they noted in a statement reported by Tot Barcelona.

“With this peaceful protest, we want to draw attention to the consequences of atmospheric pollution, which has a direct impact on the health of the population, as well as on the wellbeing of our planet.”

During the blockade, the students intend to conduct a live experiment. They will measure pollution levels while the street is closed to traffic and compare them to readings taken when vehicles are flowing freely. This will provide a stark visual demonstration of traffic’s impact on local air quality.

The organisers stressed that their action is part of a broader call for a healthier living environment, a cause that has seen various professional groups, including Catalan doctors, join public protests. “The right to clean air isn’t just a demand from environmentalists; it is a right for all people,” the statement continued. “No one should have to live in an environment where their health is at risk.”

Urban Planning Crossroads

The protest on Marina Street underscores the complex challenge facing Barcelona. While city-level policies appear to be yielding positive results, their effects are not felt evenly across all neighbourhoods. The demonstration reflects a growing public demand for more targeted interventions in areas like Eixample, a district already undergoing significant urban transformation, including the major redevelopment of the former La Model prison site.

As Barcelona continues its efforts to become a greener, healthier city, the actions of young activists like those at Institut Angeleta Ferrer serve as a powerful reminder that for many, the fight for clean air is far from over.
