Europe's Air Pollution Crisis: What's The Cause?

Air pollution is a significant issue in Europe, causing approximately 250,000 to 300,000 premature deaths annually. While air quality has improved over the last two decades, it remains a pressing health concern. Fine particulate matter (PM2.5) and nitrogen dioxide (NO2) are the main contributors to air pollution-related deaths, causing respiratory and cardiovascular illnesses, as well as cancers. Southern and Eastern European countries tend to have higher levels of PM2.5 and NO2, with Northern Italy, Poland, and the Czech Republic experiencing elevated mortality rates. Despite the EU's efforts to reduce pollution through policies and directives, such as the Ambient Air Quality Directive, and the commitment of individual countries, air pollution in Europe remains a challenge, with urban citizens being the most affected.

Energy consumption and agriculture are the biggest sources of air pollution in Europe

Despite significant improvements in air quality in Europe since 2003, air pollution remains the leading environmental health risk in Europe and the 10th leading cause of death in the European Union. Energy consumption and agriculture are the biggest sources of air pollution in Europe.

In 2021, 97% of the EU's urban population was exposed to concentrations of fine particulate matter (PM2.5) above the latest guidelines of the World Health Organization (WHO). PM2.5 is the most harmful of air pollutants and is associated with premature mortality. In 2022, the number of deaths in the EU attributable to PM2.5 fell by 45%, moving the EU closer to achieving the 55% reduction target outlined in the zero-pollution action plan for 2030.

Residential, commercial, and institutional energy consumption was the principal source of PM2.5 in 2020, responsible for 58% of emissions. The manufacturing and extractive industry, as well as the road transport sector, were also significant sources of PM2.5. Energy consumption in the residential, commercial, and institutional sectors was also the main source of CO and BC emissions, contributing to 46% and 37% of total emissions, respectively.

Agriculture was an important source of PM10, contributing significantly to emissions of particulate matter. The agriculture sector was the principal source of ammonia and methane in 2020, responsible for 94% and 56% of total emissions, respectively. Agriculture was also the second-largest source of CH4 emissions, at 27%. Ammonia emissions have decreased only slightly in many Member States since 2005 and, in some cases, have increased.

Other sources of air pollution in Europe include domestic heating, transport, power generation, and industry. Southern and eastern Europe remain pollution hotspots, with PM2.5 and PM10 levels highest in northern Italy and eastern Europe. High NO2 levels, associated with vehicle emissions, were mainly observed in northern Italy and some areas of western Europe, such as the south of the United Kingdom, Belgium, and the Netherlands.

Fine particulate matter (PM2.5) is the air pollutant with the most negative health impacts

Fine particulate matter (PM2.5) is a mixture of solid particles and liquid droplets found in the air. These particles are so small that they can be inhaled and enter the bloodstream, causing serious health issues. PM2.5 is composed of particles with diameters of 2.5 micrometres or less, making them 30 times smaller than the average human hair. Due to their minuscule size, PM2.5 particles can be inhaled deeply into the lungs, causing adverse health effects, especially in vulnerable groups such as infants, children, older adults, and individuals with pre-existing heart or lung conditions.

PM2.5 is recognised as the most harmful of air pollutants by the World Health Organization (WHO). According to the WHO's guidelines, short-term exposure to PM2.5 has been linked to respiratory diseases, including asthma and chronic obstructive pulmonary disease (COPD). Long-term exposure to PM2.5 has been associated with premature death, particularly in people with chronic heart or lung diseases. Research from the California Air Resources Board (CARB) supports this, indicating that children exposed to high levels of PM2.5 experience slower lung growth and have smaller lungs at age 18 compared to those living in areas with lower PM2.5 levels.

The sources of PM2.5 pollution vary, with energy consumption and agriculture being the primary contributors in Europe. Other sources include industrial emissions, vehicle exhaust, smoke from fires, and dust. In 2021, 97% of the urban population in the EU was exposed to PM2.5 concentrations above the WHO guidelines. Southern and Eastern Europe, particularly Northern Italy and Eastern Europe, have reported the highest levels of PM2.5.

Despite improvements in air quality over the past two decades, PM2.5 pollution remains a significant issue. Between 2005 and 2022, the number of deaths in the EU attributable to PM2.5 fell by 45%. However, air pollution is still the largest environmental health risk in Europe, causing an estimated 239,000 premature deaths in 2022 alone. The EU has set a zero-pollution target for 2050 and is working towards tightening air quality standards to reduce permitted pollution levels of PM2.5.

Air pollution is the leading cause of death for children under 18 in Europe

Air pollution is a major issue in Europe, and it is the leading cause of death for children under 18. According to the European Environment Agency (EEA), air pollution causes over 1,200 premature deaths per year in this age group across the EEA's 32 member countries. This figure represents a significant burden of chronic illness and loss of future potential. Children are particularly vulnerable to the effects of air pollution as their bodies and immune systems are still developing.

The main sources of air pollution in Europe are traffic, heating, and industry. While emissions have declined in recent years, air pollution levels remain a serious health risk. Fine particulate matter (PM2.5) is one of the most harmful pollutants, causing respiratory and cardiovascular diseases, including asthma, and even cancer. Exposure to PM2.5 during pregnancy is linked to low birth weight and an increased risk of pre-term birth. In 2021, 97% of the urban population in the EU was exposed to PM2.5 levels above the World Health Organization (WHO) guidelines.

Central and Eastern European countries, such as Poland and Croatia, along with Italy, have reported the highest concentrations of PM2.5. This is primarily due to the burning of solid fuels like coal for domestic heating and industrial use. Other pollutants, such as ozone (O3) and nitrogen dioxide (NO2), also pose significant risks to health, especially for children's lung function and development. The Mediterranean region and Central Europe have been found to have the highest ozone levels.

To address this issue, the European Commission has set a goal under the European Green Deal's Zero Pollution Action Plan to reduce PM2.5-related deaths by 55% by 2030 compared to 2005 levels. The EU is working towards tightening air quality standards and reducing permitted pollution levels. However, despite these efforts, air pollution remains a significant challenge, and the air in Europe is still not safe for children and adolescents. More stringent policies and measures are needed to protect the health and well-being of Europe's youth.

In summary, air pollution is the leading cause of death for children under 18 in Europe, with over 1,200 premature deaths estimated annually. Fine particulate matter, ozone, and nitrogen dioxide are key pollutants contributing to this issue. While there have been improvements in air quality over the years, Europe continues to struggle with unsafe air pollution levels, necessitating further action to safeguard the health and future of its younger generations.

Air pollution is the biggest environmental health risk in Europe

Despite improvements in air quality over the past two decades, air pollution remains a significant issue in Europe. The European Environment Agency (EEA) estimates that in 2021, there were at least 253,000 deaths in the EU attributable to exposure to fine particulate matter (PM2.5) above the recommended levels. Nitrogen dioxide pollution caused 52,000 deaths, and short-term exposure to ozone led to 22,000 deaths in the EU. These pollutants are linked to asthma, heart disease, stroke, and lung cancer.

The EU has implemented policies to improve air quality, such as the Ambient Air Quality Directive and the National Emission Reduction Commitments Directive. However, many EU countries do not comply with the air pollution limits, which are weaker than WHO guidelines. The UK, for example, has been in breach of EU air quality limits since 2010. The EU Court of Auditors has criticized governments for not adequately addressing the air quality crisis.

Air pollution also impacts Europe's economy, resulting in increased healthcare costs, reduced life expectancy, and lost working days. It damages vegetation, ecosystems, water and soil quality, and local ecosystems. Lower socio-economic groups tend to be exposed to higher levels of air pollution, and older people, children, and those with pre-existing health conditions are more susceptible to its effects.

To address the issue, the EU is working towards a zero-pollution vision for 2050 and is developing new rules to achieve this goal. The European Council and Parliament have agreed on a new EU Air Quality Directive to tighten air quality standards and reduce permitted pollution levels.

Eastern and Southern Europe are pollution hotspots

Air pollution is the leading environmental threat to public health in Europe, and it is the tenth leading cause of death in the European Union. According to the World Health Organization (WHO), tens of millions of people in Europe live and work in areas where air pollution levels exceed the maximum recommended limits.

The burning of solid fuels for domestic heating and industry is a major contributor to the high levels of air pollution in Eastern and Southern Europe. Fossil fuel use, in particular, is a key driver of poor air quality in Southeast Europe. Fossil fuel combustion contributes between 29% to 35% of outdoor PM2.5 exposures in Southeast European countries. In 2019, North Macedonia had the highest annual average of PM2.5 exposures in the region, while Romania had the lowest.

Air pollution is linked to a range of health issues in Eastern and Southern Europe. In Southeast Europe, air pollution was linked to one in ten deaths in the region, with the largest numbers of deaths among people aged 70 or older. More than 56,000 deaths were linked to air pollution in Southeast Europe in 2019, and the average death rate was nearly four times higher than in Western Europe. Exposure to air pollution can also impact the health of newborns, accounting for 7.7% of infant deaths in Southeast Europe in 2019.
