Economic Impacts of Air Pollution on Public Health

Air pollution imposes a substantial economic burden by driving up healthcare expenditure, reducing labour productivity and undermining quality of life. Fine particulate matter and gaseous pollutants increase rates of respiratory and cardiovascular illness, leading to higher hospital admissions, medication costs and insurance premiums. Beyond physical health, prolonged exposure contributes to mental health disorders, amplifying welfare losses and social care needs. Adverse effects on worker performance and attendance translate into lost output, diminished firm-level productivity and threats to economic growth. Traffic accidents exacerbated by reduced visibility and cognitive impairment constitute an indirect cost that is often overlooked. Vulnerable groups—children, the elderly and socioeconomically disadvantaged communities—bear a disproportionate share of this burden, heightening health inequities. Economic evaluations of the social cost of air pollution increasingly inform policy, demonstrating that investment in emission controls, urban planning and clean-energy transitions yields substantial returns in improved public health and enhanced gross domestic product per capita. The global scale of these impacts underscores the importance of coordinated regulation and cross-sector collaboration to mitigate risks and sustain economic development.

Research from Nature Portfolio

Recent studies have quantified the causal link between air pollution and mental health, using large-scale digital search data to construct daily indicators of psychological distress. Results show that sustained exposure to fine particulate matter exacerbates anxiety and depression, with stronger effects among middle-aged and married individuals. Cities with higher per capita income, more green space and better access to sports facilities exhibit attenuated impacts, suggesting that public infrastructure and economic capacity can buffer health risks. A one-standard-deviation increase in fine particulate concentration is estimated to raise the number of people experiencing mental health problems by over one million, highlighting the overlooked economic and social benefits of air quality improvements.

Economic Impacts of Air Pollution on Public Health publication trend

The graph below shows the total number of articles in economic impacts of air pollution on public health across all publications each year (not limited to Nature Index journals).

Technical terms

PM2.5: Fine particulate matter with a diameter of 2.5 micrometres or less, capable of penetrating deep into the lungs and bloodstream.

Health externality: Uncompensated impact of pollution on individuals’ health that is not reflected in market prices.

Disability-adjusted life year (DALY): A metric combining years of life lost due to premature mortality and years lived with disability to quantify disease burden.

Labour productivity: Output produced per unit of labour input, often expressed as output per worker or per hour worked.

Morbidity and mortality: Respectively, the incidence of disease or ill health in a population and the incidence of death.
