Air pollution is one of the world's most pressing health and environmental problems, with human activity being the primary cause. It is estimated that 8.1 million premature deaths occur annually due to air pollution, making it the leading environmental cause of disease and premature death. The dominant take, make, waste linear economy, fueled by cheap and abundant energy, is a significant contributor to this issue. Household combustion devices, motor vehicles, industrial facilities, and forest fires are common sources of air pollution, releasing harmful pollutants such as particulate matter, carbon monoxide, ozone, nitrogen dioxide, and sulfur dioxide. The impact of air pollution extends beyond health, with economic consequences totaling $6 trillion in annual global health costs and losses in productivity. Additionally, global waste is projected to increase to 3.4 billion tons by 2050, exacerbating the challenges of pollution management.

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. This figure has increased over the past two decades. It is the single largest environmental health risk in Europe and the largest environmental threat to human health worldwide. It is responsible for 8.1 million premature deaths annually, killing more people than tobacco.
The World Health Organization (WHO) has published evidence that links air pollution to type 2 diabetes, obesity, systemic inflammation, Alzheimer's disease, and dementia. It also impacts neurodevelopment, leading to lower cognitive test outcomes, negatively affecting mental and motor development. Air pollution is also damaging children's lung function, even at lower levels of exposure.
The primary sources of human-made air pollution are vehicle emissions, fuel oils, and natural gas used to heat homes. By-products of manufacturing and power generation, particularly coal-fueled power plants, and fumes from chemical production are also major contributors. Nature also releases hazardous substances, such as smoke from wildfires, ash and gases from volcanic eruptions, and methane from decomposing organic matter in soils.
Air pollution is a mix of hazardous substances from both human-made and natural sources. The main pathway of exposure is through the respiratory tract. Pollutants with the strongest evidence for public health concern include particulate matter (PM), carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2), and sulfur dioxide (SO2). Fine particulate matter is especially harmful as these very small particles can penetrate deep into the lungs, enter the bloodstream, and travel to organs, causing systemic damage to tissues and cells. Almost every organ in the body can be impacted by air pollution, and it can lead to inflammation, oxidative stress, immunosuppression, and mutagenicity in cells throughout the body.
By reducing air pollution, we can save and improve millions of lives, tackle climate change, build fairer societies, and strengthen economies.

The economic impact of air pollution
Air pollution has a significant economic impact, affecting productivity, healthcare costs, and overall economic activity. It is a major risk factor for premature deaths, with 8.1 million deaths attributed to air pollution each year. The World Bank estimates that the health damage caused by air pollution costs $6 trillion annually, or 5% of global GDP. This includes costs associated with environmental damage, lost ecosystem services, and reduced life expectancy.
Air pollution also hampers workforce productivity, with 1.2 billion workdays lost globally every year, which could reach 3.8 billion by 2060. This includes work absences and reduced productivity due to pollution-related illnesses and premature deaths. Poor air quality also impacts talent recruitment, as cities with severe air pollution are viewed as less desirable places to work.
However, there is an economic incentive to reduce air pollution. The implementation of clean air policies and technologies can boost economic growth. For example, the EU economy has gained €50-60 billion annually since 2014 due to improved air quality. Similarly, the estimated economic benefits of integrated pollution management policies could be as high as $2.4 trillion by 2040. In the US, every $1 spent on air pollution control yields $30 in economic benefits.
Overall, the economic impact of air pollution is significant, and addressing this issue through clean air policies and technologies can have substantial economic and health benefits.

Air pollution and climate change
Air pollution is a major global issue that severely impacts public health and the environment. It is the leading environmental cause of illness and premature death worldwide, with 8.1 million deaths attributed to it annually. The health effects of air pollution include asthma, strokes, heart attacks, cancer, dementia, low birth weight, stillbirths, miscarriages, and more. The World Health Organization (WHO) reports that 99% of people breathe air that exceeds their guideline limits, with those in low- and middle-income countries suffering the most.
Air pollution also exacerbates climate change and harms biodiversity and ecosystems. Many air pollutants, such as black carbon, tropospheric ozone, and methane, are short-lived climate pollutants (SLCPs) that have a much greater warming potential than carbon dioxide (CO2). SLCPs contribute to global warming, intensify smog, increase allergenic air pollutants, and threaten food security by decreasing agricultural yields.
Addressing air pollution is crucial in tackling the climate crisis. Reducing air pollution improves human health, strengthens economies, and mitigates climate change. Lower levels of air pollution result in better cardiovascular and respiratory health for populations. Additionally, reducing ambient and household air pollution can lower carbon dioxide (CO2) emissions and SLCP emissions, providing near- and long-term benefits for the climate.
Despite the urgency of the issue, clean air projects are often underfunded, and many countries lack pollution standards. However, there is some progress, with countries like Colombia and Mali integrating air pollution considerations into their national climate plans. Implementing policies and practical measures to reduce emissions is essential for improving air quality and mitigating climate change.

Air pollution and children
Air pollution is the largest environmental threat to human health worldwide. According to the World Health Organization (WHO), 93% of children under the age of 15 years (approximately 1.8 billion children) breathe polluted air that puts their health and development at serious risk.
Children are more susceptible to air pollution than adults due to their developing organs and weaker immune systems. Their breathing rates are also higher than those of adults, and they inhale a larger fraction of air through their mouths, which allows pollution to penetrate deep into their lower respiratory tract. As a result, air pollution is linked to several adverse health effects in children, including respiratory infections, asthma, reduced lung function, allergies, and an increased risk of adult chronic diseases. It also impacts their neurodevelopment and cognitive abilities, affecting their mental and motor development.
Moreover, air pollution contributes to negative pregnancy outcomes, including miscarriages, premature births, and low birth weight. In 2016, the WHO estimated that 600,000 children died from acute lower respiratory infections caused by polluted air. Additionally, children who grow up breathing high levels of air pollution are at an increased risk of developing lung diseases later in life.
To reduce the impact of air pollution on children, it is crucial to implement policies that improve air quality around schools, kindergartens, and other child-centric settings. Families can also play a role by monitoring air quality and adjusting their activities to limit exposure during periods of high pollution. Promoting healthy diets and lifestyles can further help reduce the overall impact of air pollution on children's health.
By addressing air pollution and taking steps to protect children from its harmful effects, we can save and improve millions of lives, build fairer societies, and foster stronger economies.
