Air Pollution: A Priority Issue For Our Health And Planet

Air pollution is a critical issue that poses significant risks to human health and the environment. It refers to the contamination of the atmosphere by various chemical, physical, and biological agents, including particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulfur dioxide. The sources of air pollution are diverse and context-specific, ranging from household combustion devices and motor vehicles to industrial facilities and forest fires. The consequences of air pollution are far-reaching, leading to respiratory diseases, strokes, heart diseases, lung cancer, and other severe health issues. It claims millions of lives annually and imposes substantial costs on healthcare systems. Additionally, air pollution affects ecosystems, vegetation, water and soil quality, and has economic implications, such as lost labor income and reduced talent recruitment in severely polluted areas. Addressing air pollution is crucial for protecting public health, mitigating environmental damage, and minimizing economic losses associated with poor air quality.

Air pollution is harmful to human health and well-being

Air pollution is a pressing issue that poses significant risks to human health and well-being. It refers to the contamination of the indoor or outdoor environment by chemical, physical, or biological agents that alter the natural composition of the atmosphere. The World Health Organization (WHO) has identified air pollution as the "new tobacco," underscoring its detrimental effects on human health.

One of the primary ways air pollution harms human health is by increasing the risk of respiratory diseases and other ailments. Fine particulate matter in the air, resulting from both ambient and household pollution, leads to strokes, heart diseases, lung cancer, and acute and chronic respiratory illnesses. According to WHO data, almost the entire global population (99%) breathes air that exceeds the recommended guideline limits for pollutant levels. This situation is particularly acute in low- and middle-income countries, where exposures to pollutants are the highest.

The consequences of air pollution extend beyond physical health. It also impacts mental well-being and quality of life. For example, poor outdoor air quality can negatively affect job performance, even for those working indoors at desk jobs. Additionally, air pollution can disrupt daily business operations and increase healthcare costs, affecting the economy and people's livelihoods.

Vulnerable populations bear the brunt of the adverse effects of air pollution. Lower socioeconomic groups tend to be exposed to higher levels of air pollution, and communities of color and low-income neighborhoods are disproportionately affected due to the historical siting of highways and polluting facilities in their proximity. Environmental racism further exacerbates the issue, with outdoor laborers, including migrant and seasonal farmworkers, being among the most vulnerable to air pollution and the least equipped to advocate for their right to clean air.

The sources of air pollution are diverse and context-specific, making it a complex issue to address. However, major outdoor pollution sources include residential energy use for cooking and heating, vehicles, power generation, agriculture, waste incineration, and industry. By targeting these sources and implementing sustainable practices, such as those promoted by the WHO, we can mitigate the health risks associated with air pollution and improve the well-being of people worldwide.

It disproportionately affects vulnerable communities and people of colour

Air pollution is a pressing issue that disproportionately affects vulnerable communities and people of colour. This disparity arises from various social, economic, and environmental factors that converge to place an unequal burden on these communities.

One key factor is the historical and ongoing practice of environmental racism, where communities of colour are more likely to be located near sources of industrial pollution, such as power plants, factories, and waste disposal sites. This is a direct result of discriminatory policies and practices that have segregated communities and relegated people of colour to areas with poorer environmental conditions. As a result, these communities bear the brunt of exposure to toxic air pollutants, leading to a range of adverse health effects, including respiratory illnesses, cardiovascular diseases, and even cancer.

Additionally, vulnerable communities often face

It has economic costs, including lost labour income and reduced talent recruitment

Air pollution is a pressing issue that has far-reaching economic consequences, including lost labour income and reduced talent recruitment. The World Health Organization (WHO) has underscored the severity of the problem, likening air pollution to "the new tobacco". The economic implications of air pollution are significant, with an annual global economic cost of $225 billion in lost labour income alone.

The impact of air pollution on labour income is twofold. Firstly, it directly affects the health of workers, leading to increased morbidity and mortality rates. The presence of fine particulate matter, ozone, and nitrogen dioxide in the air has been linked to an increased risk of strokes, heart disease, lung cancer, and acute and chronic respiratory diseases. These health issues not only impact the quality of life for those affected but also result in reduced labour productivity and increased healthcare costs. Secondly, air pollution disrupts daily business operations, including transportation and supply chains. Traffic congestion caused by air pollution can hinder the efficient movement of goods and services, further contributing to economic losses.

The talent recruitment aspect is closely tied to the liveability of cities and regions with severe air pollution problems. Highly skilled workers tend to consider not just salary and career opportunities but also the quality of life a location can offer when deciding where to live and work. Cities with poor air quality may become less desirable, making it more challenging for companies to attract top talent. This dynamic was evident in a survey by Bain & Company and the American Chamber of Commerce in China, which found that 53% of American firms operating in Chinese cities faced difficulties in recruiting senior talent, with air pollution being the primary factor.

The economic costs of air pollution extend beyond labour income and talent recruitment. Air pollution can also influence consumer behaviour and spending patterns. For example, a Yale study found that Spanish consumers spent significantly less, up to $50 million less, on days with higher ozone pollution. As consumers become more aware of the health risks associated with air pollution, their purchasing decisions may be influenced by a location's air quality. This can impact businesses operating in areas with poor air quality, potentially driving consumers towards companies perceived as environmentally responsible or operating in less polluted regions.

Addressing air pollution is not just an environmental or health issue but also an economic imperative. By investing in solutions to tackle air pollution, businesses and governments can foster a healthier, more productive workforce while also enhancing their reputation and talent attraction capabilities. Furthermore, the development and implementation of innovative technologies to reduce air pollution can create new economic opportunities, such as those in the clean energy and sustainable development sectors.

It contributes to climate change, with sources including transportation and building operations

Air pollution is a pressing issue as it significantly contributes to climate change, with transportation and building operations acting as key sources. Transportation's role in air pollution is well-known, as the burning of fossil fuels like gasoline and diesel releases carbon dioxide and other greenhouse gases into the atmosphere. The transportation sector accounts for about 28% of total US greenhouse gas emissions, making it the largest contributor.

Initiatives like SmartWay by the EPA aim to improve supply chain efficiency, reduce greenhouse gases, and save fuel costs for freight transportation companies. Additionally, the EPA has required labels on vehicles indicating their fuel economy, fuel costs, and ratings on greenhouse gas emissions. These measures encourage the use of more fuel-efficient vehicles, reducing transportation's impact on air pollution.

Building operations also play a significant role in air pollution and climate change. The built environment generates 40% of annual global greenhouse gas emissions, with building operations responsible for 27% of those emissions. Natural gas use in buildings contributes to greenhouse gas emissions and is a health and safety risk, as it can negatively impact indoor air quality. Burning natural gas indoors can lead to unhealthy levels of nitrogen dioxide, carbon monoxide, and formaldehyde, which can be especially harmful to children and the elderly.

Furthermore, electricity use in buildings contributes to about 4% of total emissions, with associated emissions from electricity generation contributing as well. Climate-driven changes in weather conditions, including temperature and precipitation increases, are expected to worsen existing air pollution and negatively impact both outdoor and indoor air quality.

The effects of air pollution are far-reaching, causing harm to human health and well-being, reducing the quality of life, and impacting the economy. Therefore, addressing air pollution, particularly from transportation and building operations, is crucial in mitigating climate change and minimizing its detrimental effects on human society and the environment.

It causes morbidity and mortality, with 7 million premature deaths annually linked to air pollution

Air pollution is a pressing issue that significantly impacts human health and well-being, making it a priority concern. It is a major health and economic burden, causing morbidity and reducing quality of life. Morbidity refers to the state of being ill or unhealthy, and air pollution is a significant contributor to various diseases and health conditions. According to the World Health Organization (WHO), almost the entire global population (99%) breathes air that exceeds the recommended guideline limits and contains high levels of pollutants. This has severe consequences for human health.

Outdoor and indoor air pollution cause respiratory and other diseases and are significant sources of morbidity and mortality. Fine particulate matter in the air, such as PM2.5, is a leading cause of cancer, especially lung cancer. Chronic exposure to air pollution can affect every organ in the body, exacerbating existing health conditions. Children are particularly vulnerable as their bodies and immune systems are still developing, and they have little power to improve air quality.

The health impacts of air pollution are evident in the high number of premature deaths it causes annually. According to the WHO, the combined effects of ambient (outdoor) and household air pollution are associated with 7 million premature deaths each year. This is a staggering figure that underscores the urgency of addressing air pollution. These premature deaths are often due to strokes, heart diseases, lung cancer, and acute and chronic respiratory diseases caused by air pollution.

The issue of premature mortality due to air pollution is not limited to a specific region but is a global concern. For instance, in Europe, air pollution-related morbidity and mortality have decreased in recent decades, yet it still remains a significant risk factor for health. Data from 43 European countries between 1990 and 2019 revealed that the majority (90.4%) of all deaths associated with PM2.5 were due to ischemic heart disease (IHD). Additionally, in 2019, exposure to PM2.5 and NO2 led to thousands of years lived with disabilities (YLDs) due to chronic obstructive pulmonary disease and diabetes mellitus in multiple European countries.

Addressing air pollution is crucial not only for improving public health but also for mitigating its economic impacts. The global economy loses $225 billion annually due to lost labor income caused by air pollution. Additionally, businesses operating in severely polluted cities may face challenges in talent recruitment, as skilled professionals may be reluctant to live and work in such environments. Therefore, tackling air pollution is a priority issue that requires urgent attention to protect human health, reduce premature deaths, and minimize economic losses.
