To date, four EU Clean Air Fora have taken place in Paris (2017), Bratislava (2019), Madrid (2021) and Rotterdam (2023). These have facilitated the coordinated implementation of EU legislation and policies related to improving air quality. 

In 2025, the Fifth EU Clean Air Forum will be hosted by the European Centre for Medium-Range Weather Forecasts (ECMWF) at the World Conference Center in Bonn. The event will take place from 1 December at 13:00 to 2 December at 16:00.

The sessions will cover the following topics: 

  • Earth observation and clean air
  • Artificial intelligence and machine learning for air quality analysis
