Overview
- Provisional 2025 readings show citywide NO2 declines of roughly 4% to 12%, with the Eixample traffic station falling from 33 to 29 µg/m³ year over year.
- PM10 and PM2.5 levels remained stable within current EU annual limits, and all stations complied with EU standards even as levels still exceed WHO guidelines and fall short of the stricter 2030 aims.
- City leaders tie the progress to fleet renewal and the low‑emission zone, noting Eco and Zero‑label vehicles now make up 31% of traffic overall and 38% of passenger cars, while label B has dropped to 12%.
- Health officials estimate pollution‑attributable deaths declined to about 1,100 in 2025, down from roughly 1,900 in 2018–2019.
- A new monitoring station on Avinguda Meridiana is being added to expand coverage, as civic groups question some Eixample readings and experts urge deeper traffic reductions to meet future targets.
