Air Pollution's Economic Impact On Europe

Air pollution is a pressing issue in Europe, causing around 300,000 premature deaths annually and affecting the economy in various ways. It contributes to increased healthcare costs, reduced life expectancy, and lost working days across sectors. The economic impact of air pollution in Europe is significant, and it is essential to address this challenge to protect both the health and economic well-being of European citizens.

Healthcare costs

Air pollution in Europe has significant impacts on healthcare costs, with economic losses amounting to billions of euros annually. The health impacts of air pollution include increased mortality and morbidity, leading to higher healthcare expenditures and reduced productivity.

The economic burden of air pollution-related diseases and deaths in Europe is substantial. According to a World Health Organization (WHO) study, the economic cost of approximately 600,000 premature deaths and diseases caused by air pollution in the WHO European Region in 2010 was US$ 1.6 trillion. This amount is almost equivalent to one-tenth of the gross domestic product (GDP) of the entire European Union in 2013. The study also highlights that the economic value of deaths and diseases due to air pollution reflects the amount societies are willing to pay to avoid these outcomes.

The impact of air pollution on healthcare costs is evident in specific regions and cities as well. For instance, in the metropolitan area of Skopje, the social cost of premature mortality due to air pollution was estimated at between 570 and 1470 million euros in 2012. Additionally, air pollution was responsible for hospital admissions for cardiovascular and respiratory diseases, further contributing to healthcare expenditures.

Industrial air pollution, particularly from the energy sector, has been a significant contributor to the economic costs associated with health impacts. Over the last decade, external costs caused by industrial air pollution in Europe decreased by nearly 35%, mainly due to improvements in the energy sector. However, significant costs persist, and further reductions in pollution levels are necessary to mitigate the societal costs.

The economic burden of air pollution extends beyond healthcare costs, including productivity losses and harm to ecosystems. Implementing clean air measures is crucial to reducing these economic costs and boosting economic growth. According to Bruegel's analysis, clean air action can increase economic growth by €50-60 billion annually in the European Union.

Reduced life expectancy

Air pollution is a major issue in Europe, impacting both the environment and the economy. One of the most concerning consequences of air pollution is its effect on life expectancy. Here are some key points on how air pollution reduces life expectancy, specifically in the context of Europe:

Impact on Life Expectancy in Europe

Air pollution has a significant impact on the life expectancy of Europeans. According to the European Environment Agency, in 2022, an estimated 239,000 premature deaths were caused by exposure to fine particulate matter (PM2.5), with an additional 70,000 and 48,000 premature deaths linked to ozone and nitrogen dioxide levels, respectively. These pollutants are known to contribute to respiratory diseases such as asthma, as well as heart disease and stroke.

Global Impact of Air Pollution on Life Expectancy

Research has shown that exposure to air pollution shortens the average person's lifespan by approximately 1.8 to 2.3 years. This impact is comparable to other major drivers of death and disease, such as cancer, tobacco smoking, and inadequate water/sanitation/hygiene. Lower-resourced areas and regions with older populations tend to suffer the most severe impacts on life expectancy due to air pollution.

Health Risks of Air Pollution

The health risks associated with air pollution are well-documented. Fine particulate matter (PM2.5) is of particular concern as it is small enough to enter the lungs and even the bloodstream, causing serious health problems. Exposure to air pollution can lead to respiratory diseases, including asthma, lung cancer, and an increased risk of stroke. It is estimated that in 2021, 97% of people living in European urban areas were exposed to concentrations of PM2.5 above the recommended levels set by the World Health Organization (WHO).

Economic Impact of Reduced Life Expectancy

Improving Air Quality in Europe

Despite the challenges, Europe has made strides in improving air quality over the past few decades. The EU has adopted strict policies and measures to reduce air pollution, and emissions of the main air pollutants have decreased significantly since the 1980s. However, more efforts are needed to meet the recommended levels set by the WHO and to achieve the EU's zero pollution vision for 2050.

Lost working days

Air pollution has a significant impact on Europe's economy, and one of the factors contributing to this is lost working days. Air pollution is the leading environmental health risk in Europe, causing and exacerbating respiratory and cardiovascular diseases. The most common causes of premature deaths attributable to air pollution are heart disease and stroke, followed by lung diseases and lung cancer. These health issues not only result in personal suffering but also impose significant costs on the healthcare sector.

The impact of air pollution on lost working days is evident in the productivity losses and absenteeism among workers. Studies have shown that exposure to fine particulate matter, such as PM2.5, can lead to an increase in absenteeism at work. This is because air pollution can trigger and worsen respiratory and cardiovascular conditions, leading to more sick days and reduced labour productivity. The costs associated with absenteeism and reduced productivity can be substantial, affecting businesses and the overall economy.

In addition to the direct impact on workers' health, air pollution can also influence productivity through its effects on cognitive function. Research suggests that exposure to air pollution can impair cognitive performance, including decision-making abilities and concentration. This can result in decreased productivity and efficiency in the workplace, further contributing to lost working days.

Moreover, air pollution can also have indirect effects on labour productivity by impacting agricultural output. For example, ground-level ozone can damage crops and reduce yields, as observed in many EU countries in 2019, leading to economic losses. This, in turn, can affect the availability of certain products and disrupt supply chains, causing further economic losses and potentially contributing to lost working days in industries reliant on these agricultural products.

To mitigate the impact of air pollution on lost working days, it is crucial to implement effective policies and regulations aimed at reducing air pollution. This includes enforcing stricter emission standards, promoting cleaner technologies, and encouraging sustainable practices in various sectors, such as agriculture, industry, transport, and energy. By reducing air pollution levels, the number of lost working days due to health issues and cognitive impairments can be decreased, contributing to a stronger and more productive economy in Europe.

Damage to vegetation and ecosystems

Air pollution in Europe has a detrimental effect on vegetation and ecosystems, causing economic losses and threatening the environment. Ground-level ozone (O3) is a key pollutant, damaging agricultural crops, forests, and plants by reducing growth rates, yields, and biodiversity. In 2022, almost a third of Europe's agricultural lands were exposed to O3 levels above the EU's threshold for vegetation protection, resulting in crop damage and economic losses. This issue is not new; in 2019, economic losses due to O3's impact on wheat yields totalled EUR 1.418 billion across 35 European countries.

O3 is a secondary pollutant, formed when other pollutants, such as nitrogen oxides (NOx) and volatile organic compounds, react in the atmosphere with sunlight. It impairs plant photosynthesis, slowing growth and increasing vulnerability to pests and diseases. At the ecosystem level, high O3 levels can drive species loss, alter ecosystem structure, and impact habitat quality.

Nitrogen deposition, caused primarily by ammonia (NH3) from agriculture and NOx from combustion, also poses a significant threat. Excessive nitrogen in water bodies contributes to eutrophication, leading to algal blooms and reduced oxygen availability. In sensitive terrestrial ecosystems, such as grasslands, exceeding critical nitrogen levels can result in the loss of sensitive species, favouring species that thrive in high-nitrogen environments, and altering ecosystem structure and function.

The deposition of sulphur dioxide (SO2), along with NOx and NH3, can lead to acidification, disrupting ecosystems and causing biodiversity loss. While SO2 emissions have decreased in recent decades, addressing the issue of acidification, the relative contribution of NH3 and NOx to soil and water acidification has increased.

Heavy metals, transported long distances through the atmosphere, are another toxic pollutant. They accumulate in soils and the food chain, posing risks to human health, animals, and plants. Lead, cadmium, and mercury, for example, have been found in marine organisms, exceeding safe limits.

To protect vegetation, the EU has set air quality standards, including targets and critical levels for O3, NOx, and SO2. However, in 2022, only 11.2% of the total agricultural area in the EEA countries met the long-term objective for O3, indicating ongoing risks to vegetation.

Impact on water and soil quality

Air pollution has a significant impact on water and soil quality. When air pollution occurs, the precipitation that falls into water bodies and soils also becomes polluted. This is a pressing concern as soil and water are fundamental to all life on Earth, providing homes and nutrients for most organisms.

Acid precipitation, a result of air pollution, can alter soil chemistry, which in turn affects plant growth and water quality. Soils become more acidic, resulting in a decreased ability to retain essential nutrients, minerals, and elements such as calcium, magnesium, and potassium. These nutrients are then transported by water flowing through the soil, making them less accessible for land organisms.

Additionally, increased soil acidity can increase the mobilisation of heavy metals like aluminium, which are then able to flow into lakes, rivers, and streams. These heavy metals are poisonous to fish and other wildlife, remaining suspended in the water at higher acidities.

Air pollution also affects water bodies, causing short-term but dramatic acidification or long-term acidification from ongoing exposure to acid precipitation. This "acid shock" can be fatal for aquatic organisms, while eutrophication, or rapid and significant increases in plant and algal growth, can deplete oxygen resources needed by other organisms.

The effects of air pollution on water and soil quality have far-reaching consequences, impacting the health of ecosystems and organisms, including humans, that depend on these natural resources.
