Pollution has a significant impact on the economy, with poor air quality causing a vast array of economic costs. These include healthcare costs associated with pollution-related illnesses and deaths, environmental damage, reduced productivity, and decreased tourism. In 2018, air pollution cost the global economy USD 2.9 trillion, equivalent to 3.3% of the world's GDP. Similarly, the US economy lost roughly 5% of its GDP in 2014 due to air pollution, with the highest costs attributed to early deaths caused by exposure to fine particulate matter (PM2.5). Nutrient pollution also affects the economy, with nitrates and algal blooms in drinking water sources increasing treatment costs and negatively impacting the tourism, fishing, and shellfish industries. Historical air pollution has also contributed to the poverty and deprivation in certain areas of metropolitan cities, such as London, Paris, and New York.

Healthcare costs
Air pollution has a significant impact on healthcare costs, contributing to adverse health outcomes and increased healthcare expenditure. It poses a severe threat to global public health, with far-reaching economic consequences.
Numerous studies have examined the impact of air pollution on healthcare costs, particularly respiratory diseases. Research in Beijing, China, found a significant positive impact of PM2.5 on healthcare expenditure for respiratory illnesses, including drug and antibiotic costs. Another study using data from 30 Chinese provinces concluded that industrial waste-gas emissions affected health expenditures. The impact of air pollution on healthcare costs varies with income levels, with low-income groups facing different challenges than high-income groups.
The Environmental Protection Agency's BenMAP-CE tool is widely used to estimate the healthcare costs associated with air pollution. This tool considers hospital admissions and emergency department visits, but a more comprehensive assessment should include ambulatory and other care expenses. By including these additional categories, the estimated healthcare costs can increase by approximately 40% for respiratory and cardiovascular patients.
The health consequences of air pollution lead to increased healthcare utilisation and costs. For example, air pollutants can exacerbate pre-existing conditions and contribute to the development of respiratory and cardiovascular diseases. The impact of air pollution on mortality is also significant, affecting future productivity and economic growth.
The economic burden of air pollution is substantial, with health costs from climate change and fossil fuel pollution exceeding $820 billion annually in the United States alone. These costs include hospitalizations, injuries, mental health ailments, and lost wages. The transition to a clean energy economy is crucial to reducing these healthcare expenses and promoting public health.

Lost productivity
Air pollution has a significant impact on workforce productivity and economic activity. Poor air quality has been linked to decreased productivity at work, and it is estimated that 1.2 billion workdays are lost globally each year due to air pollution, a figure that could rise to 3.8 billion by 2060. This loss of productivity has a substantial economic impact, with the World Bank estimating that the health damage caused by air pollution costs $6 trillion annually, equivalent to a 5% reduction in global GDP. This figure includes the costs of lost productivity and reduced life expectancy, as well as healthcare expenditures associated with pollution-related illnesses.
The impact of air pollution on productivity is evident in various sectors of the economy. For example, the burning of fossil fuels contributes to poor air quality and has been associated with significant costs. The average American incurs around $2,500 in additional medical bills due to air pollution exposure from fossil fuels. When higher temperatures lead to increased ozone pollution, the health costs in the United States rise even further, reaching $7.9 billion annually due to worsened asthma and other health issues.
The agriculture sector is another significant contributor to air pollution, particularly through human activities such as manufacturing and transportation. In 2014, agriculture was responsible for $230 billion in air pollution damages in the United States alone, making it the economic sector with the highest level of damages. The impact of air pollution on this sector has far-reaching consequences, including global crop yield losses of 3-16%.
While the costs of air pollution are substantial, it is important to note that taking action to improve air quality can have significant economic benefits. Research has shown that the economic gains associated with air pollution mitigation can outweigh the costs by a factor of up to 30. For example, a reduction in air pollution in the EU has boosted its economy by €50-60 billion annually since 2014.
Overall, the impact of air pollution on productivity and economic activity is undeniable, and addressing this issue through clean air initiatives and sector-specific emissions reductions can lead to substantial economic gains and stronger, more sustainable economies.

Impact on tourism
Tourism is one of the fastest-growing industries, contributing more than 10% to the global GDP. However, the impact of tourism on the environment, and the resulting economic consequences, are significant. The tourism sector accounts for about 5% of global CO2 emissions, with aviation contributing to 40% of those emissions. Local pollution at tourist destinations includes air emissions, noise, solid waste, littering, sewage, oil and chemicals, architectural/visual pollution, heating, car use, and water pollution.
Tourism can have a detrimental impact on rivers, which can be excessively extracted and polluted by the demands of tourists. Noise pollution can also disturb wildlife, and light pollution can disrupt the feeding and reproductive behaviour of many creatures. The increase in food and beverages consumed by tourists creates waste plastic and non-biodegradable products. Coastal areas are particularly vulnerable to these impacts, as well as rising sea levels due to climate change.
Tourism can also impact the socio-cultural environment, bringing both benefits and challenges. Tourism may increase awareness of certain environmental issues, but it can also lead to the neglect of environmental concerns to satisfy tourist demands. Tourist destinations located in the wild may contribute to issues such as pollution and deforestation. The interaction between tourists and locals can foster cultural exchange, but differing expectations and values can also cause friction. Some researchers argue that contact with Western tourists leads to the destruction of pre-existing cultures and the growth of capitalist values and consumer culture.
The economic impacts of tourism are significant, with tourist spending contributing about US$1.45 trillion to the global economy in 2019. Tourism can create jobs and business opportunities for local craftsmen and improve transportation and telecommunications in an area. However, the degradation of the natural environment due to tourism can also have economic consequences, impacting waste and wastewater treatment, food security, raw materials, and ecosystem functions.

Property values
Environmental considerations are now a crucial factor in the analysis of real estate. The presence of pollution can significantly impact property values, with consequences for homeowners, investors, and communities.
Air quality has become one of the most important factors in evaluating property and its demand. Clean air can raise the value of a nearby home by up to 25%, and cities with cleaner atmospheres tend to have higher property prices and demand. Conversely, air quality risk areas have lower real estate prices and sluggish markets. Research by the National Bureau of Economic Research found that a 10% improvement in air quality can increase housing markets by 4%.
Water cleanliness can also impact property prices. Waterfront property values can decline due to the unpleasant sights and odours of algal blooms, which are caused by nutrient pollution. Similarly, the presence of toxic pollutants in water can lower real estate prices, while clean water can increase property rates.
Soil pollution can also affect property values. Potential buyers may be concerned about the health risks of living near old factories, brownfields, or landfills, which can lower the value of the property.
The impact of pollution on property values is complex, and the time it takes for property values to recover after environmental remediation depends on the effectiveness of the clean-up action. If the situation worsens or continues, the chances of property values recovering are much lower.

Crime rates
While the link between pollution and crime has been largely overlooked, there is a growing body of research that suggests a strong correlation between the two. Studies have found that exposure to air pollution can increase violent crime rates, with a particular impact on aggravated assaults and other violent crimes. This relationship may be due to the adverse health effects of air pollution, which can cause respiratory irritation, depression, anxiety, and increased stress hormone levels, leading to higher risk-taking and aggressive behaviour.
For example, a study of 9,360 US cities found a positive correlation between air pollution and crime, with a 10-point raise in the air quality index (AQI) resulting in a 0.9% increase in the crime rate. Similarly, research in London, UK, found that air pollution had a statistically significant impact on overall crime and several major crime categories, including those with economic motives. The study also revealed that the effect occurred at pollution levels well below current regulatory standards.
The link between pollution and crime has important implications for policy and law enforcement. Improving air quality in urban areas through tighter environmental policies and regulations may provide an effective way to reduce crime rates. Additionally, law enforcement resources can be more effectively deployed by incorporating information from pollution forecasts, a strategy known as predictive policing.
Furthermore, the impact of pollution on crime extends beyond violent crimes. For instance, high levels of air pollution have been associated with increased fraud, possibly due to people choosing to stay indoors and engage in more online activities to avoid exposure to polluted air.
While the exact physiological mechanism behind the link between pollution and crime remains unclear, the existing research suggests that reducing air pollution could have significant benefits not only for public health but also for reducing crime and its associated costs.
