Looking ahead, a new national air quality index will be introduced in 2025, aligning more closely with WHO recommendations and providing actionable health advice through the UBA's air quality app.

Germany achieved a significant milestone in 2024 by complying with all European air quality standards for the first time, as reported by the Federal Environment Agency (UBA) on February 20, 2025.

The WHO recommends significantly lower air quality thresholds than those currently enforced, highlighting the need for ongoing improvements.

Despite meeting the limits, nitrogen dioxide (NO2) levels in Germany were reported to be close to the threshold, with averages of 40 micrograms per cubic meter in Essen and 39 micrograms in Munich.

This compliance indicates full adherence to the European air quality directive, based on preliminary data from approximately 600 monitoring stations across the country.

A new European air quality directive, which came into effect in December 2024, introduces stricter targets to be met by 2030, including a reduction of the NO2 limit to 20 micrograms per cubic meter and PM2.5 to 10 micrograms.

The preliminary data shows a clear trend towards improved air quality, with final results expected in mid-2025.

The Federal Environment Agency noted that current air quality limits are still above World Health Organization (WHO) recommendations, prompting future targets that aim to halve the NO2 annual mean.

UBA President Dirk Messner attributed the recent improvements to targeted air quality measures, including stricter vehicle emissions standards and the electrification of public transport.

These improvements were also linked to the upgrading of vehicle fleets, an increase in electric cars, and retrofitting of particulate filters on older vehicles.

In 2023, 44% of monitoring stations exceeded the future NO2 limit of 20 micrograms per cubic meter, indicating further enhancements are necessary before 2030.

In urban areas, efforts included reducing speed limits, which have been shown to contribute to lower pollution levels.
