Europe's Air Gets Cleaner: Policy Pays Off

Europe's air quality is seeing sustained improvement, a positive outcome of decades of dedicated environmental policy. The EU's Copernicus Atmosphere Monitoring Service (CAMS) reports that while localized pollution issues persist, the overall trend is encouraging. This progress is largely driven by substantial emission reductions in key sectors.

Since 2015, emissions of sulfur oxides (SOx) and nitrogen oxides (NOx) have decreased annually by three to five percent across the EU. These reductions are most notable in industry and road transport sectors. The increasing adoption of electric vehicles and a greater reliance on renewable energy sources for electricity generation are significant contributors.

However, challenges remain, particularly with extreme weather events. Heatwaves, intense sunlight, and stagnant air conditions in the summer period can accelerate ozone formation, a harmful pollutant. Furthermore, prolonged dry conditions can escalate wildfire activity, which drastically impacts air quality, as seen with the record wildfires in August last year that heavily affected Portugal and Spain.
