Air Pollution: Economic Costs And Health Hazards

Air pollution is detrimental to economies worldwide, causing a vast array of economic costs. These costs arise from healthcare expenditures associated with pollution-related illnesses and deaths, environmental damage, lost ecosystem services, and decreased workplace productivity and tourism. In 2018, air pollution cost the global economy USD 2.9 trillion, or 3.3% of the world's GDP. The World Bank estimates that the health damage caused by air pollution costs USD 6 trillion annually, or 5% of global GDP. Air pollution also disproportionately affects disadvantaged communities and developing economies, exacerbating inequalities. However, research shows that the economic benefits of air pollution mitigation can outweigh the costs, providing a strong case for investing in cleaner technology and green industry development.

Reduced productivity, work absences and premature deaths

Air pollution has a detrimental impact on productivity, causing a reduction in workforce efficiency and an increase in absences. In 2019, India lost an estimated $95 billion, or 3% of its GDP, due to these issues. Globally, 1.2 billion workdays are lost each year due to air pollution, which could rise to 3.8 billion by 2060. This results in a 5% reduction in global GDP, according to the World Bank.

The health impacts of air pollution are a key driver of these losses. Poor air quality affects the entire body and can lead to a range of diseases, impacting physical and mental health. This results in increased healthcare costs, which can affect both individuals and governments. In the US, for example, air pollution was estimated to cost $790 billion in 2014, with the highest costs coming from early deaths attributable to fine particulate matter exposure.

Premature deaths due to air pollution also have a significant economic impact. Research has shown that 85% of the economic benefits of mitigating air pollution come from reducing premature deaths tied to particulate matter pollution exposure. A study in China found that a 10 mg/m3 decrease in PM2.5 would reduce healthcare spending by over $9.2 billion.

The economic impact of air pollution extends beyond healthcare costs and productivity losses. It also affects talent recruitment, with cities with severe air pollution being less desirable places to work. Additionally, air pollution can have intergenerational effects, impacting the economic well-being of future generations. For example, children whose parents were exposed to less air pollution were more likely to attend college and have higher expected earnings.

Overall, the costs of air pollution are significant, and addressing this issue is crucial for both the health and economic well-being of societies.

Healthcare costs and environmental damage

Air pollution has a detrimental impact on human health and the environment, leading to a range of economic costs. Poor air quality has been linked to a variety of illnesses and diseases, resulting in increased healthcare costs and reduced productivity in the workplace.

Healthcare costs associated with air pollution-related illnesses and deaths can be substantial. In the United States, for example, cardiovascular disease and respiratory conditions caused by air pollution were estimated to result in $820 billion in annual healthcare costs. The burning of fossil fuels, which contributes to poor air quality, has also been associated with additional medical bills for individuals, with an average American spending around $2,500 more due to air pollution exposure from fossil fuels.

The impact of air pollution on healthcare costs is not limited to the United States. Globally, the health damage caused by air pollution is estimated to cost $6 trillion annually, according to the World Bank. This corresponds to a 5% reduction in global GDP, considering factors such as health impacts, lost productivity, and reduced life expectancy.

In addition to the direct healthcare costs, air pollution also has indirect economic impacts through environmental damage. Air pollution can damage vegetation, ecosystems, water and soil quality, and local ecosystems. The decline in ecosystem functionality has been estimated to cost more than $5 trillion per year due to the loss of services provided by biodiversity, such as food provisioning, carbon storage, and water and air filtration.

The economic costs of air pollution-related environmental damage are significant. For example, in Europe, the environmental and health costs of industry have decreased by a third from 2012 to 2021, showing that addressing air pollution can have a positive economic impact. Additionally, the implementation of clean air action plans, such as the National Clean Air Action Plan in China, has been shown to have substantial health and economic benefits, further emphasizing the importance of addressing air pollution to improve economic welfare and growth rates.

Economic growth and clean air action

Air pollution is responsible for a wide range of economic costs. These costs are incurred through healthcare expenditures, environmental damage, lost ecosystem services, and reduced productivity. The World Bank estimates that the health damage caused by air pollution costs $6 trillion a year, or 5% of global GDP. This figure includes losses from reduced workforce productivity, staff absences, premature deaths, and lower crop yields.

Clean air action, on the other hand, is profitable and can boost economic growth. For example, reducing air pollution in line with World Health Organization guidelines could prevent 17,000 premature deaths each year in the UK, saving £1.6 billion annually. Similarly, a 10 mg/m3 decrease in PM2.5 would reduce China's annual healthcare spending by more than $9.2 billion. In the United States, damages from air pollution have fallen by 20% between 2008 and 2014, resulting in significant economic gains.

The economic benefits of air pollution mitigation are significant. Research on the Clean Air Act in the United States found a 30:1 ratio between the economic benefits and the costs of air pollution mitigation. This translates to an 85% return on investment in the form of reduced premature mortality, improved productivity, and increased tourism. By addressing air pollution, businesses can improve their bottom line and contribute to sustainable economic growth.

Furthermore, clean air measures can help achieve the UN's Sustainable Development Goals (SDGs), particularly those related to health, sustainable cities, environmental sustainability, industrialization, and reducing inequality. Companies across diverse industries, including transport, technology, and retail, are recognizing the importance of clean air and are committed to reducing their air pollution footprint. By prioritizing clean air, businesses can attract environmentally conscious customers and stakeholders, enhancing their reputation and long-term sustainability.

Overall, addressing air pollution is not only crucial for public health but also makes economic sense. By investing in clean air technologies and practices, governments and businesses can reduce healthcare costs, increase productivity, and promote sustainable economic growth. The benefits of clean air action extend beyond financial gains, contributing to a healthier, more equitable, and environmentally sustainable future for generations to come.

Inequality and environmental hazards

Air pollution is the leading environmental risk to health, causing approximately 7 million premature deaths each year. It is also closely linked to climate change and harms ecosystems, causing global crop yield losses of 3-16%. The economic burden of pollution associated with premature mortality and morbidity is significant, estimated at 5-14% of countries' GDPs.

Inequality in the distribution of wealth and power is central to how societies function and malfunction. Inequality, not per capita income, might be the underlying cause of environmental degradation. Research has shown that countries with higher income inequality and fewer political rights and civil liberties tend to have more polluted air and water. Power imbalances facilitate environmental degradation, and the poor suffer the consequences. For example, polluting power plants and hazardous waste dumps are located in poor neighbourhoods.

Economic disparities have long been suspected to be a root cause of environmental inequality. However, the relationship between income and air pollution exposure is relatively weak. While individuals with higher incomes tend to live in cleaner neighbourhoods, racial gaps in pollution exposure persist. Even large increases in income appear to have little effect on an individual’s pollution exposure.

Environmental inequality research has important health implications. Low socioeconomic status (SES) communities face higher exposure to air pollutants and other environmental hazards, increased susceptibility to poor health, and health disparities driven by environmental factors. For instance, in most low- and middle-income countries, women and children bear the brunt of the impacts of household air pollution. They spend the most time in polluted living spaces and have higher rates of exposure to particulate matter and other pollutants emitted by stoves and open fires.

Overall, air pollution exacerbates inequality and disproportionately affects low-income communities, racial minorities, and vulnerable populations. Addressing economic and social inequality is crucial not only for improving public health but also for mitigating environmental degradation.

Multigenerational economic opportunities

Air pollution has a significant impact on economies worldwide, with a range of economic costs. It affects businesses through reduced workforce productivity, staff absences, and lower crop yields. For instance, in 2019, India lost an estimated $95 billion, or 3% of its GDP, due to reduced productivity, work absences, and premature deaths caused by air pollution. Similarly, China's economy is hit with a bill of around $900 billion annually, while the US economy loses $600 billion each year.

The costs associated with air pollution are not limited to the present but also extend to future generations. Research suggests that exposure to fine particulates during pregnancy can impact not only the exposed woman and the child she carries but also the grandchildren. This exposure has been linked to lower educational attainment and reduced earnings, affecting the economic health of the first and second generations.

The economic burden of air pollution is evident in healthcare expenditures, environmental damage, and lost ecosystem services. Poor air quality increases healthcare costs due to pollution-related illnesses and deaths, with the World Bank estimating a $6 trillion annual loss, or 5% of global GDP. Additionally, commercial activities such as energy production, agriculture, and transport contribute significantly to particulate matter emissions, impacting the economy.

However, addressing air pollution can bring significant economic gains. For example, the Clean Air Act in the United States has successfully reduced pollution, improved health, and increased worker productivity. Since 1970, cleaner air has coincided with economic growth, creating market opportunities and innovations in cleaner technologies. The Act has also resulted in avoided premature deaths, reduced illnesses, and prevented lost workdays, further contributing to a stronger economy.

Furthermore, air pollution control equipment presents economic opportunities. In 2008, this equipment generated revenues of $18 billion globally, with exports accounting for $3 billion. The environmental goods and services market is substantial, comparable to the aerospace and pharmaceutical industries, offering prospects for economic growth and technological advancements.

In conclusion, air pollution has far-reaching economic consequences, affecting businesses, healthcare costs, and future generations. However, tackling air pollution through regulations, innovations, and control equipment can yield significant economic benefits, improve public health, and enhance overall economic growth.
