Air pollution is one of the deadliest environmental risks facing Europe today. According to the European Environment Agency (EEA), exposure to fine particulate matter (PM2.5)—a mix of tiny particles from sources like dust, smoke, and soot—was responsible for approximately 239,000 premature deaths in Europe in 2021. Another 48,000 people died from nitrogen dioxide (NO2) exposure. While air pollution affects the entire continent, the impact is disproportionately felt in some regions, particularly in Central and Eastern Europe.
The Health Impact of Air Pollution in Europe
Air pollution, including both PM2.5 and NO2, is linked to a wide range of serious health issues. These include lung cancer, heart disease, stroke, respiratory illnesses, and poor birth outcomes. Older adults are particularly vulnerable, with air pollution responsible for about 4% of deaths among those aged 65 and older. The effects are not limited to these direct health outcomes; air pollution also exacerbates other chronic conditions, contributing to overall lower quality of life.
In addition to respiratory and cardiovascular diseases, recent studies have linked air pollution to male infertility, while noise pollution—often coexisting with air pollution in urban areas—is emerging as a potential factor in female infertility. This underlines the far-reaching implications of polluted environments on both physical and reproductive health.
Regional Disparities: A Growing Divide in Europe
Although air pollution is a continent-wide issue, some regions of Europe are hit much harder than others. Central and Eastern European countries experience the highest mortality rates linked to PM2.5 exposure. A recent report from the European Commission and the Organisation for Economic Co-operation and Development (OECD) highlights countries like Poland, the Czech Republic, and Northern Italy as having particularly elevated rates of PM2.5-linked deaths. These regions are heavily impacted by residential pollution sources such as coal heating systems and emissions from the agricultural sector.
In contrast, Western and Southern Europe see higher levels of nitrogen dioxide (NO2) mortality, driven largely by traffic emissions and industrial activity. Major urban centers in cities like Madrid, Rome, and Paris are most affected by this type of pollution.
A map provided in the report illustrates the disparity in PM2.5-related deaths across Europe. The East-West divide is evident, with the wealthier, more industrialized nations in the West showing lower death rates from particulate pollution, while Eastern nations with lower GDPs struggle to mitigate pollution's harmful effects.
The Role of Government and Policy
The European Union has taken important steps to address air pollution in recent years. In 2021, the World Health Organization (WHO) revised its air quality guidelines, recommending stricter thresholds for annual concentrations of nitrogen dioxide and PM2.5. The European Union, in turn, adopted a set of stricter air quality rules aimed at aligning with WHO guidelines by 2030. These new regulations mandate that member states monitor key pollutants like fine particulate matter, black carbon, and ammonia.
Mark Nieuwenhuijsen, director of the Barcelona Institute for Global Health, describes the EU's updated policy as "one of the biggest public health interventions for a generation." The regulations are expected to reduce the number of PM2.5-related deaths by 55% by 2030.
Additionally, countries like Denmark are taking bold steps to reduce their environmental impact, with plans to implement a carbon tax on livestock farming by 2030. This could make Denmark the first country in the world to regulate methane emissions from livestock as part of its broader strategy to reduce air pollution.
Challenges Ahead: A Complex Problem
Despite these efforts, challenges remain. Many EU countries still exceed WHO-recommended air quality levels for nitrogen dioxide, and the effects of air pollution continue to worsen in some areas. Researchers like Nieuwenhuijsen and Zorana Jovanovic Andersen, a professor of environmental epidemiology at the University of Copenhagen, emphasize that the health risks associated with air pollution are now understood to occur at lower levels of exposure than previously thought.
Even with substantial reductions in air pollution, public health experts warn that it may not be possible to entirely eliminate the health impacts, as pollution tends to overlap with other environmental stressors. Factors such as noise pollution, lack of green spaces, and extreme weather events linked to climate change compound the harmful effects of polluted air, further complicating the task of improving overall health outcomes.
The Need for Continued Action
While there is progress in reducing air pollution in many parts of Europe, experts argue that more needs to be done. Air pollution remains one of the top environmental health threats on the continent, and regulatory measures must continue to evolve to address new challenges. "We know how to reduce air pollution, and many countries are leading the way," says Andersen. "But there are new challenges emerging, and we need to continue regulating air pollution in the name of public health."
Air pollution may be a longstanding problem, but with the right policies and actions, Europe can work toward healthier air quality for all its citizens.
