Increase in Air Pollutant Emissions Across EU-27 Nations from 2010 to 2023
In a groundbreaking development, the EU-27 Member States have witnessed substantial reductions in air pollutant releases over the past decade, as revealed in the latest version (14.0) of the European Pollutant Release and Transfer Register (E-PRTR), published in March 2025.
The top five industries responsible for the highest reduction in pollutant releases are primarily those associated with combustion and heavy industrial processes. These industries have achieved these significant pollution reductions due to improved technologies, fuel switching, and stricter EU policies.
1. **Electricity Producers** Significant reductions in emissions of nitrogen oxides (NOx), sulfur oxides (SOx), and particulate matter (PM10) reflect a shift away from coal combustion and improved environmental performance in power generation.
2. **Iron and Steel Works** This sector also saw marked decreases in pollutant releases, particularly SOx, NOx, and particulate matter, driven by modernized processes and better emission controls.
3. **Cement Plants** Cement production traditionally produces large emissions; however, it experienced substantial declines in air pollutants through process improvements and fuel changes.
4. **Other Combustion-Related Industrial Activities** Industries with significant combustion processes showed widespread emission reductions, consistent with the EU's transition to cleaner fuels and technologies.
5. **Heavy Metals Emission Sources (e.g., facilities emitting Cadmium, Mercury, Lead)** Although emissions of heavy metals are lower in volume and vary naturally, industries under strict regulation showed reductions as part of broader efforts to limit toxic substances.
These trends reflect an over 50% reduction in pollutant releases such as SOx, NOx, PM10, and heavy metals since 2010 across most EU countries, with some pollutants like heavy metals decreasing by more than 75%. The improvements are attributed significantly to EU policies such as the Industrial Emissions Directive and continuous enforcement of emission limits, as well as economic recovery and growth enhancing efficiency.
It is important to note that the calculation does not consider any gap-filled data, and the table does not provide information about pollutant releases from non-EU countries, sources other than industries, or pollutant releases into water or land. Additionally, data from Czechia, Malta, Lithuania, Slovakia was not considered due to gap filling of non-reported data.
In conclusion, the industries with the most notable decreases are those involved in power generation, iron and steel production, cement manufacturing, and other heavy industrial combustion processes, all benefiting from regulatory frameworks and technological advancements aimed at reducing air pollution. This progress underscores the EU's commitment to environmental sustainability and public health.

- The reduction in air pollutants from Environmental-Science, specifically studying and implementing technologies to reduce emissions, has played a crucial role in the Decrease of emissions from the industries mentioned above, such as electricity producers, iron and steel works, cement plants, and other combustion-related industrial activities.
- Financial incentives from the government and investors, focusing on cleaner production methods, have contributed to the industrial organizations' compliance with stricter emission standards, thereby significantly reducing air pollution.
- In the context of the advancements in Environmental-Science, it is essential for environmental agencies to collaborate with industry leaders to further enhance the efficiency of pollutant reduction, ensuring not only improved air quality but also the long-term sustainability of industrial processes and the overall Environmental-Science sector.
