Air Pollution Awareness In The Eu: Who Cares?

Air pollution is a pressing issue in Europe, with almost everyone across the continent living in areas with dangerous levels of air pollution. It is the single largest environmental health risk in Europe and a major cause of premature death and disease. The most vulnerable groups, such as lower socio-economic groups, older people, children, and those with pre-existing health conditions, are more susceptible to the harmful effects of air pollution. While the EU has implemented strict measures to reduce air pollution and emissions have decreased significantly since the 1980s, the air quality in many European cities still exceeds the recommended levels, posing a risk to the health and well-being of its citizens.

Air pollution's impact on human health

Air pollution is a major threat to global health and prosperity, causing more than 6.5 million deaths each year worldwide. It is caused by a mix of hazardous substances from both human-made and natural sources. While the effects of air pollution on human health vary depending on the type of pollutant, the length and level of exposure, and individual health risks, it primarily enters the body through the respiratory tract, leading to inflammation, oxidative stress, immunosuppression, and mutagenicity in cells throughout the body, impacting the lungs, heart, and brain, among other organs.

Particulate matter (PM), composed of chemicals such as sulfates, nitrates, carbon, or mineral dust, is one of the most important air pollutants leading to disease. Fine particulate matter (PM2.5), in particular, is extremely harmful as it can be inhaled deeply into the lung tissue, contributing to serious health problems. It can also enter the bloodstream and travel to other organs, causing systemic damage to tissues and cells. Exposure to PM2.5 has been linked to increased risks of various cancers, including lung, colorectal, and prostate cancers, as well as cardiovascular disease, respiratory diseases, and adverse birth outcomes.

Ozone (O3), a ground-level atmospheric gas often referred to as smog, is another significant pollutant. It is created when pollutants from cars, power plants, and industrial processes react with sunlight. Ozone, along with other noxious gases like carbon monoxide (CO), nitrogen dioxide (NO2), and sulfur dioxide (SO2), can irritate the eyes and throat and damage the lungs, especially in children, the elderly, and those who work or exercise outdoors.

In Europe, air pollution remains the largest environmental health risk, causing an estimated 300,000 premature deaths each year. Energy consumption and agriculture are the biggest sources of air pollution on the continent. The most deprived people in society often face higher levels of exposure to air pollution due to their proximity to busy roads or industrial areas. Additionally, regions with lower GDP per capita, particularly in Eastern and Southeastern Europe, tend to have higher levels of PM2.5 due to the combustion of low-quality solid fuels for domestic heating.

While there are signs of improvement, with emissions of various pollutants decreasing significantly between 1990 and 2021, the impact of air pollution on human health remains a critical issue. The World Health Organization's latest data shows that in 2021, 97% of the EU's urban population was exposed to fine particulate matter (PM2.5) levels above their guidelines. This highlights the ongoing challenge of mitigating the health risks associated with air pollution and the need for stricter air quality standards and legislative measures.

The economic burden of air pollution

Air pollution has a significant economic impact, with a global cost of up to an estimated $5 trillion annually. Burning fossil fuels, such as gas, coal, and oil, has been linked to three times as many deaths as road traffic accidents worldwide, and air pollution has a substantial economic burden, estimated at $2.9 trillion, or 3.3% of global GDP. This figure takes into account the costs associated with environmental damage, lost ecosystem services, and healthcare expenditures related to pollution-related illnesses and deaths.

In 2018, air pollution was linked to 4.5 million deaths, 1.8 billion workdays lost, 4 million new cases of child asthma, and 2 million preterm births worldwide. The economic costs of air pollution are diverse and far-reaching, including healthcare costs, reduced productivity, work absences, and premature deaths. For example, in 2019, India's economy lost an estimated $95 billion, or 3% of its GDP, due to the impacts of air pollution.

In Europe, air pollution is the largest environmental health risk, causing an estimated 300,000 premature deaths annually. While emissions of the main air pollutants in the EU have decreased significantly since the 1980s, with an 80% reduction in the energy sector from 2012 to 2021, air pollution still poses a significant economic burden. The EU's urban population is exposed to high levels of fine particulate matter (PM2.5), with 97% living in areas exceeding World Health Organization (WHO) guidelines in 2021.

The economic costs of air pollution in Europe are significant, with impacts on healthcare, agriculture, and ecosystem services. For instance, in 2019, several EU countries lost more than 5% of their wheat yield due to ground-level ozone (O3), resulting in substantial economic losses. Furthermore, lower socio-economic groups in Europe tend to be exposed to higher levels of air pollution, with vulnerable populations facing increased health risks and potential healthcare costs.

The most vulnerable groups to air pollution

Air pollution is a significant environmental health risk in Europe, causing an estimated 300,000 premature deaths annually. While everyone is susceptible to the harmful effects of air pollution, some groups are more vulnerable than others. Here are some of the most vulnerable groups:

• People of colour: People of colour are disproportionately affected by air pollution due to various factors. They are more likely to live in polluted areas, close to sources of pollution, and face higher rates of chronic conditions such as asthma, diabetes, and heart disease, which increase their susceptibility to the health impacts of air pollution.
• Individuals with lower incomes: Lower-income communities often reside in proximity to industrial areas or busy roads, leading to increased exposure to air pollution. They may also experience psychosocial distress and chronic stress due to a lack of safety, green spaces, and access to high-quality food, making them more vulnerable to pollution-related health issues.
• Pregnant individuals: Pregnancy is a uniquely vulnerable stage when it comes to air pollution. Exposure to air pollution during pregnancy has been associated with adverse outcomes such as premature birth, low birth weight, and an increased risk of hypertensive disorders like preeclampsia. The physical changes and stress of pregnancy, combined with exposure to pollutants, can impact the growth and development of the fetus.
• Older adults: As people age, their lung capacity decreases, and their immune systems become less effective at protecting the lungs from inhaled contaminants. Older adults are also more likely to have chronic illnesses, such as lung or heart disease, which can be exacerbated by air pollution.
• Children: Children are particularly vulnerable to the effects of air pollution as it can harm their lung development and increase the risk of respiratory diseases. In EEA member and collaborating countries, over 1,200 deaths in people under 18 years of age are estimated to be caused by air pollution annually.
• Individuals with pre-existing health conditions: Those living with pre-existing health conditions, such as asthma, COPD, cardiovascular disease, or diabetes, are more susceptible to the harmful effects of air pollution. The pollutants can trigger asthma attacks and further compromise their lungs, hearts, and other organs, leading to serious health complications.

The EU's legislative response to air pollution

Air pollution is the leading environmental health risk in Europe, causing an estimated 239,000 premature deaths in 2022. The EU has adopted strict policies to improve air quality and protect the health of its citizens. The EU's legislative response to air pollution includes:

The European Green Deal

The European Green Deal sets out the EU's zero-pollution ambition, aiming to protect citizens and ecosystems. It includes the Zero Pollution Action Plan, which targets a 55% reduction in premature deaths caused by air pollution by 2030, relative to 2005 levels.

Ambient Air Quality Directives

The EU's Ambient Air Quality Directives establish standards for 12 air pollutants, including particulate matter (PM2.5 and PM10), nitrogen oxides (NOx), sulphur dioxide (SO2), and ammonia (NH3). These directives also outline methods for monitoring, assessing, and informing the public about air quality.

National Emission Reduction Commitments Directive

The National Emission Reduction Commitments Directive sets national targets for reducing five key air pollutants: NOx, non-methane volatile organic compounds (NMVOCs), SO2, NH3, and PM2.5. Member states are expected to prepare air quality plans to address responsible sources and ensure compliance when levels exceed limit values.

Revised Air Quality Rules

In April 2024, the EU Parliament adopted revised air quality laws to align with the Zero Pollution Action Plan's 2050 goal. These laws set stricter limits for 2030, targeting pollutants with severe health impacts, including PM2.5, nitrogen dioxide (NO2), and SO2. The rules also enable legal action and compensation for those affected by air pollution.

Directives on Specific Pollutants

The EU has directives focusing on specific pollutants, such as arsenic, cadmium, mercury, nickel, and polycyclic aromatic hydrocarbons.

Cooperation and Support

The EU cooperates with strategic partners to address transboundary air pollution and provides financial support to member states for implementing clean air policies. The European Environment Agency (EEA) plays a crucial role in supporting these policies through data, indicators, and assessments, including the annual air quality report.

The impact of air pollution on the environment

Air pollution has a significant impact on the environment, causing harm to human health, plants, animals, and natural ecosystems. It is caused by various human activities, such as burning fossil fuels, industrial emissions, and energy consumption, and it poses a substantial risk to people's well-being and the planet's delicate balance.

One of the primary ways air pollution affects the environment is by contributing to climate change. Greenhouse gas emissions, particularly carbon dioxide, trap heat in the Earth's atmosphere, leading to global warming and rising temperatures worldwide. This phenomenon has far-reaching consequences, including the melting of ice sheets, warming oceans, and more frequent extreme weather events. As a result, ecosystems are changing at a rapid pace, often faster than plants and animals can adapt, leading to species extinction and disrupting the balance of entire ecosystems.

Air pollution also affects the quality of the air we breathe, with fine particulate matter, ozone, and nitrogen dioxide levels exceeding World Health Organization recommendations in many parts of Europe. This has severe health implications, causing respiratory diseases such as asthma, lung cancer, and stroke, and resulting in premature deaths. According to estimates, air pollution claims the lives of around 300,000 people in Europe annually, including over 1,200 individuals under 18 years of age in EEA member and collaborating countries.

In addition to its impact on human health, air pollution also harms vegetation. Ozone pollution, for instance, damages stomata, tiny pores on the underside of leaves that enable plants to breathe, hindering their growth. Acid rain, lead toxicity, and nitrogen oxide exposure alter the chemical composition of the soil, depriving plants of essential nutrients. This, in turn, affects agriculture, forests, and grasslands, with significant economic repercussions.

Furthermore, air pollution can reduce visibility and block sunlight. The presence of pollutants in the air, such as haze and smog, obscures shapes and colours, impacting our ability to see clearly. Additionally, air pollution contributes to the acidification of aquatic ecosystems, as carbon dioxide dissolves in seawater, leading to ocean acidification, which makes it challenging for marine species to develop shells and skeletons.

Overall, air pollution has far-reaching consequences for the environment, affecting ecosystems, human health, and economic stability. Addressing this issue requires a concerted effort to reduce emissions, improve air quality, and mitigate the impacts of climate change to protect both human well-being and the delicate balance of nature.
