Air pollution is a pressing issue in the United States, with nearly half of Americans exposed to dangerous levels of air pollution between 2021 and 2023. While public awareness of the health risks associated with air pollution is high, specific knowledge about the impacts on health is lacking. Americans are particularly unaware of the neurological health problems caused by air pollution, and the disproportionate impact on certain communities. With the Trump administration rolling back clean air regulations, there are concerns about the future of air quality in the United States and its potential impact on public health.
| Characteristics | Values |
|---|---|
| Americans' awareness of air pollution's health impact | 73% of Americans are aware that air pollution from fossil fuels harms human health. However, only 55% can name a specific health impact, with general issues like breathing problems and respiratory illness being the most frequently cited. |
| Air quality across the U.S. | 46% of Americans (approximately 156 million people) live in areas with unhealthy air quality, earning "F" grades from the American Lung Association for ozone or particle pollution. This is a regression from previous years, with climate change, heat, drought, and wildfires driving these changes. |

There are also plans to reconsider programs under the Clean Air Act, such as vehicle emissions standards and power plant regulations. |
| Health consequences | Air pollution is linked to asthma attacks, particularly in children, outdoor work sickness, low birth weight in babies, and an increased risk of lung cancer and other serious medical conditions. |
| Vulnerable populations | People of color, particularly Latino Americans, are more likely to be exposed to toxic air pollutants, experiencing environmental racism due to the deliberate location of heavy industry and other polluting sources in communities of color. |
What You'll Learn
Americans' understanding of air pollution's health impact
Americans' understanding of the health impacts of air pollution varies. While 73% of Americans are aware that air pollution from fossil fuels is harmful to human health, only about half can name specific health consequences. The most frequently mentioned health impacts include general respiratory problems, such as breathing issues and respiratory illnesses, rather than specific conditions like asthma.
A nationally representative survey conducted in 2018 by the Yale Program on Climate Change Communication and the George Mason University Center for Climate Change Communication provides insights into Americans' understanding. When asked about the health effects of air pollution from fossil fuels, 73% of participants acknowledged its harm to human health. However, when prompted to name specific health problems caused by air pollution, only 55% could provide at least one example.
The survey responses revealed a lack of awareness regarding specific health conditions linked to air pollution from fossil fuels. While some mentioned asthma and non-specific references to cancer, the majority cited general respiratory issues. This indicates a need for improved education on the diverse and specific health impacts of air pollution.
Additionally, Americans' understanding of air pollution's health effects may be influenced by their personal experiences and environments. Factors such as proximity to industrial pollution sources, underlying health conditions, nutrition, stress, and socioeconomic status can contribute to varying health impacts among different communities. People of colour are disproportionately affected by air pollution and are more susceptible to certain health consequences.
The Environmental Protection Agency (EPA) has played a crucial role in safeguarding public health from air pollution. However, significant budget cuts in 2017 reduced funding for environmental education, impacting public awareness and potentially compromising the EPA's ability to protect citizens from the health risks associated with air pollution.

Air pollution disproportionately affects minorities
Air pollution is a pressing issue in the United States, with nearly half of the population residing in areas with dangerous levels of air pollution. While most Americans (73%) are aware that air pollution from fossil fuels is harmful to human health, disparities exist in the impact of air pollution, disproportionately affecting minorities and vulnerable communities.
Studies have consistently shown that people of color in the United States suffer disproportionately from exposure to air pollution. Research by the EPA-funded Center for Air, Climate, and Energy Solutions found that African Americans, Hispanics, Asians, and other people of color are exposed to higher levels of particulate matter pollution (PM2.5) than their white counterparts, regardless of income level or region. This disparity is attributed to various factors, including systemic racism, housing policies, and the proximity of pollution sources to disadvantaged communities.
One study examining the impact of air pollution on premature death found that Hispanics and Asians, but especially Blacks, had a higher risk than whites. Notably, income was not the primary driver of these differences, as higher-income Blacks still faced greater health risks. This suggests that other factors, such as chronic stress due to discrimination, may play a significant role in the increased vulnerability of racial and ethnic minorities.
Furthermore, a 2016 study of New Jersey residents revealed that communities with larger African American populations, lower home values, and lower median incomes were at a higher risk of premature death from long-term exposure to particle pollution. Similarly, studies of Atlanta, Georgia, showed that particle pollution disproportionately increased the risk of asthma attacks in zip codes with high poverty rates and among individuals eligible for Medicaid.
The American Lung Association has emphasized the unequal burden of air pollution, highlighting that poorer people and certain racial and ethnic groups often face higher exposure to pollutants and experience more severe health consequences. The EPA shares the goal of ensuring equal protection from environmental and health hazards for all people, regardless of race or socioeconomic status. However, budget cuts to environmental education and the rollbacks of critical clean air regulations threaten to exacerbate the existing pollution crisis and further endanger vulnerable communities.

Clean Air Act and its regulations
The Clean Air Act (CAA) is the United States' primary federal air quality law, aimed at reducing and controlling air pollution across the nation. It is one of the country's earliest and most influential modern environmental laws. The CAA is administered by the Environmental Protection Agency (EPA), in coordination with state, local, and tribal governments.
The CAA was initially enacted in 1963 and has been amended several times since, including significant changes in 1970, 1977, and 1990. The 1970 amendment, passed unanimously in the Senate and signed into law by President Richard Nixon, established the EPA and tasked it with overseeing the implementation of the CAA. This amendment set National Ambient Air Quality Standards (NAAQS) to protect public health and the environment, with a goal of achieving these standards in every state by 1975.
The 1977 amendments strengthened requirements for reducing emissions in areas not meeting NAAQS and introduced Prevention of Significant Deterioration (PSD) regulations for areas already meeting the standards. The 1990 amendments addressed issues like acid rain, ground-level ozone, and the ozone layer, with a focus on cost-effective approaches. They also expanded EPA regulation to include non-road engines, such as locomotives and marine transport.
The CAA requires the EPA to regulate emissions of toxic air pollutants from a list of industrial sources called "source categories." These pollutants include mercury, polychlorinated biphenyls (PCBs), benzene, and volatile organic compounds (VOCs). The CAA also regulates vehicle fuel standards and emission-control components for motor vehicles and non-road engines.
The CAA has substantially reduced air pollution and improved US air quality, saving trillions of dollars and countless lives annually. It has been challenged in court by both environmental groups seeking stricter enforcement and states/utilities desiring more flexibility. The CAA provides a comprehensive framework for addressing air pollution and protecting public health and the environment.

EPA's environmental education budget cuts
Air pollution is a pressing issue in the United States, with a significant impact on public health and the environment. A study by Yale University and George Mason University found that 73% of Americans acknowledge that air pollution from fossil fuels is detrimental to human health. However, the same study revealed that only 55% could name specific health consequences, with general references to respiratory issues being the most common responses.
The Environmental Protection Agency (EPA) has played a crucial role in addressing these environmental challenges. Prior to 2017, the EPA allocated over $8.7 million annually towards environmental education initiatives, aiming to raise awareness and empower the public to address environmental issues. Unfortunately, in March 2017, the EPA's education budget suffered a significant blow, with the 2018 federal budget reducing their overall funds by approximately $2.5 billion, slashing the environmental education budget by 94% to just $0.555 million.
These budget cuts have had a profound impact on the EPA's ability to carry out its mission of protecting human health and the environment. The reduction in funding has resulted in staff cuts, with the agency planning to decrease its workforce to levels not seen since the 1980s. This downsizing includes the dissolution of the Office of Research and Development, which conducts vital scientific research, and the Office of Science and Technology, which plays a key role in developing scientific guidelines for water policy.
The consequences of these cuts go beyond the EPA's internal operations. The rollbacks of over 30 critical clean air and water regulations have sparked concerns among former EPA employees, who predict that these decisions could lead to 200,000 additional premature deaths and a significant increase in preventable asthma attacks by 2050. Additionally, the EPA's shift in focus away from environmental education has the potential to negatively affect public awareness and engagement in addressing environmental challenges.
The EPA's budget cuts and changes in organizational structure have been met with criticism from various groups, including the Union of Concerned Scientists and the Environmental Protection Network (EPN). These critics argue that the EPA is becoming a political tool rather than an independent scientific agency, with its decisions driven by political agendas rather than scientific evidence and the best interests of the American public.

Air pollution's impact on children
Air pollution is a significant threat to human health at every life stage, and it is the second leading risk factor for death among children under five. According to the 2024 State of Global Air report, air pollution was linked to around 709,000 deaths in children under five, with over 70% of these deaths associated with household air pollution from cooking with polluting fuels.
Children need clean and safe air to grow up healthy. Exposure to air pollution can cause a range of adverse health outcomes in children, including respiratory problems such as asthma, bronchitis, sinusitis, and frequent colds. Studies have also found a correlation between air pollution and developmental delays in children. For example, a study in New York City found that African American and Dominican children exposed to polycyclic aromatic hydrocarbons (found in coal, tar, and incomplete combustion emissions) had lower mental development index scores and a higher likelihood of cognitive developmental delays than Caucasian children living in less polluted areas.
Additionally, air pollution can impact children's immune systems. Studies in Europe have shown that air pollution may alter both cellular and humoral immunity in children, while a study in Chile found no association with the humoral immune system. However, toxicological studies suggest that air pollution may suppress host immunity, and children in regions with higher pollution levels are at an increased risk of developing vitamin D-deficiency rickets.
In the United States, air pollution has been linked to respiratory illnesses and lung function issues in children. For example, children who relocated to states with higher levels of PM10 experienced a decline in lung function, while those who moved to states with lower PM10 levels showed improved lung function. The Children's Health Study (CHS), funded by the California Air Resources Board, examined the long-term effects of exposure to ambient ozone, particulate matter, nitrogen dioxide, and strong acid vapors on children's respiratory health in Southern California.
Furthermore, air pollution disproportionately affects people of color, with Hispanic and African American individuals more likely to live in heavily polluted communities. The EPA's rollbacks on environmental regulations have been criticized for potentially exacerbating the pollution crisis and negatively impacting vulnerable communities, including children.

Frequently asked questions
A nationally representative survey conducted in December 2018 found that 73% of Americans believe that air pollution from the use of fossil fuels harms human health. However, only about half could name a specific health impact, with most citing general consequences like "breathing problems" rather than specific illnesses like asthma or cancer.
Air pollution poses a significant threat to human health at every stage of life. It has been linked to a range of serious health conditions, including asthma, cardiovascular disease, stroke, lung cancer, and premature death. In the United States, air pollution kills more people than all transportation accidents and gun shootings combined.
Air quality in the United States has improved significantly since the 1970s, with visible air pollution becoming less frequent and widespread. Between 1970 and 2017, combined emissions of six common pollutants (PM2.5, PM10, SO2, NOx, VOCs, CO, and Pb) dropped by 73%. However, recent reports indicate that this trend may be starting to reverse, with more cities experiencing increased levels of ozone and fine particle pollution since 2015.
The United States has implemented various initiatives and regulations to address air pollution, including the Clean Air Act, the National Clean Diesel Campaign, Clean School Bus USA, and the SmartWay Transport Partnership. The Environmental Protection Agency (EPA) has also issued standards to reduce vehicle emissions and gasoline sulfur content, improving air quality. Despite these efforts, critics argue that the Trump administration's rollbacks of environmental regulations and withdrawal from the Paris Climate Agreement could hamper progress in reducing air pollution.
