Pollution is a pressing issue that poses significant risks to human health and the planet. It refers to the introduction of harmful substances or energy into the environment at a rate that exceeds the capacity for safe dispersion or storage. The main types of pollution are air, water, and land pollution, with air pollution being the leading cause of climate change. While pollution has various natural sources, human activities such as burning fossil fuels, industrialization, and deforestation play a significant role in its proliferation. The effects of pollution are far-reaching, impacting not only the environment but also human health and well-being. Vulnerable communities, particularly those with lower socioeconomic status and racial and ethnic minorities, often bear the brunt of pollution's detrimental consequences. As such, understanding the link between pollution and mental health becomes crucial. Companies with strong positive reputations are perceived as providing more value, and they attract better talent, making them more resilient to reputational risks.

Air pollution is the leading environmental cause of disease and premature death
The health effects of air pollution vary depending on the type of pollutant, the length and level of exposure, and individual health risks. Fine particulate matter, or soot, is made up of tiny particles of chemicals, soil, smoke, dust, or allergens that are carried in the air. These particles can irritate the eyes and throat and damage the lungs, especially in children, the elderly, and people who work or exercise outdoors. Soot particles can also penetrate the lungs and bloodstream and worsen bronchitis, lead to heart attacks, and even hasten death.
Another harmful pollutant is ground-level ozone, or smog, which occurs when emissions from combusting fossil fuels react with sunlight. Smog can irritate the eyes and throat and damage the lungs, particularly in vulnerable individuals. It can also trigger asthma attacks and worsen symptoms in people with asthma or allergies.
In addition to these direct health impacts, air pollution contributes to climate change, which in turn intensifies the effects of air pollution. For example, increased heat and ultraviolet radiation from climate change intensify smog formation. Additionally, climate change increases the production of allergenic air pollutants like mold and pollen, which can trigger allergic responses and asthma attacks.
The distribution of air pollution also varies across socioeconomic groups, with low-income communities often bearing a disproportionate burden of air pollution. This environmental injustice is due in part to racist zoning policies and discriminatory lending practices that have resulted in polluting industries and highways being located in or near low-income communities and communities of color. As a result, the negative health impacts of air pollution disproportionately affect these vulnerable populations.
Addressing air pollution is crucial not only for improving public health but also for mitigating climate change and promoting social justice.

Air pollution stunts economic growth and exacerbates poverty and inequality
Air pollution has a detrimental impact on economic growth, exacerbating poverty and inequality. This is evident in the correlation between rising pollution levels and economic costs for nations worldwide. The consequences of air pollution extend beyond borders, affecting neighbouring countries and the wider world. For instance, air pollution in China has resulted in increased mortality rates in South Korea due to respiratory and cardiovascular diseases.
The economic implications of air pollution are far-reaching, impacting labour productivity and health costs. In 2013, India lost approximately 8.5% of its GDP due to increased welfare expenses and labour losses caused by air pollution. The onset of winter in North India brings a haze that reduces visibility and triggers cardiovascular and respiratory illnesses. The impact of air pollution on health is significant, with premature deaths and disabilities incurring economic costs. According to a World Bank study, the global economy suffered a loss of about $225 billion in 2013 due to decreased labour income associated with premature deaths caused by air pollution.
In addition to health costs, air pollution also affects vital sectors such as agriculture and ecosystems. It reduces crop yields, impacting food production and biodiversity. Moreover, it damages cultural and historical monuments, requiring remediation or restoration. The costs of addressing these issues can be substantial.
However, taking measures to control pollution can have economic benefits. Implementing emission limit values for air pollutants has proven effective in stimulating investment in clean technologies and promoting sustainable industrialization. While certain sectors may experience job losses, others will gain employment opportunities. In the long run, environmental policies will favour the economy by encouraging more efficient resource use, and the resulting health benefits can increase GDP by up to 10%.
The relationship between economic growth and air pollution is complex. While economic growth may contribute to increased pollution levels, it also provides the resources to address environmental issues. For example, China's dramatic decline in air quality accompanied its economic success, but strong measures to reduce pollution, including clean air regulations and reducing the number of cars on the road, have led to modest improvements.

Air pollution disproportionately affects low- and middle-income countries
Air pollution is one of the leading causes of health complications and mortality worldwide, with 7 million deaths linked to it every year. According to the World Health Organization (WHO), 99% of people currently breathe air that exceeds the WHO's guideline limits for pollutants, with those living in low- and middle-income countries suffering the most.
In a study of 211 countries and territories, it was found that 7.3 billion people are directly exposed to unsafe average annual PM2.5 concentrations, with 80% of them living in low- and middle-income countries. Moreover, 716 million of the world's lowest-income people (living on less than $1.90 per day) live in areas with unsafe levels of air pollution, especially in Sub-Saharan Africa.
Air pollution levels are particularly high in lower-middle-income countries, where economies tend to rely more heavily on polluting industries and technologies. This is due to less stringent air quality regulations, the prevalence of older, more polluting machinery and vehicles, fossil fuel subsidies, congested urban transport systems, and rapidly developing industrial sectors.
In the United States, people of color are 61% more likely than white people to live in a county with a failing grade in air quality. Historically, racist zoning policies and discriminatory lending practices have kept polluting industries and highways away from white neighborhoods and turned communities of color into sacrifice zones. As a result, residents in these communities have been forced to breathe dirty air and suffer the associated health problems.
