Copenhagen: More than nine in ten Europeans still breathe air pollution above the levels that health experts call safe, and progress on one of the most damaging pollutants has all but stalled, the bloc’s environment agency reports.

The European Environment Agency laid out the findings in its latest air quality assessment, drawing on official readings from monitoring stations across the continent. The picture shows genuine gains over the past decade, yet it also exposes how far Europe remains from the tougher standards it has set for 2030.

Ground-level ozone stands out as the stubborn problem. Even as countries cut the emissions that feed it, ozone concentrations have barely moved, and hot summers keep pushing them higher. The gas irritates lungs, worsens asthma and hits older people and children hardest during heatwaves.

Fine particles tell a similar story. In 2024, at least three in ten monitoring stations recorded particulate levels above the revised EU thresholds, and almost everyone on the continent breathes concentrations that exceed World Health Organization guidance. Those particles lodge deep in the lungs and rank among the biggest environmental causes of early death in Europe.

The agency published the numbers alongside a warning that current trends will not carry the bloc to its 2030 targets on their own. It urged capitals to act faster on traffic, heating and farming, the sources that keep pumping pollutants into the air. The full status report details the gaps country by country.

The timing sharpens the message. A revised EU air quality law tightens limits and aligns them more closely with health advice, and member states must weave the new rules into national plans. The data suggests many will struggle to comply without policies that bite harder than anything they run today.

Cleaner air campaigners welcomed the honesty but pressed for money to match the ambition. They want dedicated funding for low-emission transport and building renovation, arguing that pollution drains far more from health budgets than prevention would ever cost.

Some national officials pushed back, noting that industry and transport have already slashed emissions and that further cuts grow costlier each year. They argue that ozone in particular drifts across borders and even continents, which limits what any single government can achieve alone.

The agency accepts the cross-border point but insists it cannot excuse inaction. Coordinated European rules, it says, exist precisely because dirty air ignores national lines. With another hot summer testing the continent, the report lands as a reminder that Europe’s air has grown cleaner, just not clean enough.
