Trending Now - Report: Almost 50% of US Kids Exposed to Harmful Air Pollution

WHO:

CNN - Anne Krieg, director of community & economic development department in Bangor, Maine, stated that Bangor's clean air has become an important part of the city's brand, attracting new residents.

The Guardian - Will Barrett, assistant vice-president of the ALA’s Nationwide Clean Air Policy, stated, “There’s a devaluing of children’s health by this EPA as they are weakening, delaying and repealing critical health protection.”

The Guardian - Barrett pointed to “missing deadlines for particle pollution standards, repealing vehicle standards, repealing EPA’s responsibility for protecting health against climate pollution, and even allowing for increased emissions of pollution from oil and gas facilities” as specific rollbacks.

WHAT:

Los Angeles Times - The report found that 44% of Americans, or approximately 152.3 million people, live in areas with unhealthy air, with California reporting that 82% of its residents are affected.

Los Angeles Times - San Bernardino County ranked as the most ozone-polluted county in the nation, with an average of 159.2 unhealthy ozone days.

The Guardian - The report indicates that a person of color is 2.42 times more likely than a white person to live in a community that fails all three pollution measures.

The Guardian - The report marks a 3.9 million increase in the number of people exposed to unhealthy ozone levels compared to the previous year.

The Guardian - 33.5 million children in the US, or 46% of those under 18, live in areas with failing air pollution grades.

The Guardian - 7 million children, or 10% of all children in the US, live in communities that failed all three air pollution measures.

The Guardian - 38% of the US population, approximately 129.1 million people, were exposed to unhealthy ozone levels between 2022 and 2024.

CNN - About 152 million people in the US breathe unhealthy air and live in counties with failing grades for air pollution.

CNN - 32.9 million people live in counties with failing grades for all three pollution measures.

CNN - Los Angeles has the worst ozone pollution in the country.

CNN - Bangor, Maine, has zero days of unhealthy ozone and short-term particle pollution.

WHERE:

CNN - Bangor, Maine, is noted as the only city making all three clean air lists in the ALA report.

The Guardian - The report highlights that the regions most affected by high ozone levels include southwestern states from California to Texas and much of the Midwest.

CNN - The report was published on Wednesday, April 20th, 2026.

WHY:

Los Angeles Times - The report indicates that recent federal actions could undermine California’s efforts to improve air quality, including missed deadlines for stronger particle pollution standards and rollbacks of clean vehicle regulations.

The Guardian - The report attributes worsening air quality to climate change, which is intensifying ozone pollution by boosting precursor emissions and creating conditions that allow pollutants to build up.

The Guardian - Climate change is intensifying ozone pollution by boosting precursor emissions and creating conditions that allow pollutants to build up.

The Guardian - Communities of color are disproportionately exposed to unhealthy air due to higher rates of chronic health conditions.

The Guardian - Extreme heat, drought, and wildfires have contributed to unhealthy pollution levels.

HOW:

Los Angeles Times - The report states that the EPA's February revocation of a scientific conclusion regarding climate change's threat to health is one of the most significant deregulatory actions in U.S. history.

The Guardian - The report highlights datacenters as a growing source of air pollution, with their electricity consumption projected to rise from 4.4% to as much as 12% of total US electricity within the next decade.

The Guardian - The report grades levels of ground-level ozone and measures year-round and short-term spikes in particle pollution.

The Guardian - Datacenters are identified as a growing source of air pollution, consuming roughly 4.4% of total US electricity.

CNN - The EPA defines particulate matter as a mix of solid and liquid droplets that can come from various sources including power plants and vehicles.

(UPDATED April 23, 2026 11:21 UTC)

A recent report released on Monday, reveals that 44% of Americans, or about 152.3 million people, live in areas with unhealthy air, with California notably affected as 82% of its residents are impacted. In contrast, Bangor, Maine, is highlighted as the only city making all three clean air lists in the American Lung Association report, with local officials emphasizing that the city's clean air has become an essential part of its appeal to new residents. The report also raises concerns that recent federal actions, including the EPA's revocation of a key scientific conclusion on climate change, could hinder efforts to improve air quality, particularly in California, where San Bernardino County has been identified as the most ozone-polluted county in the nation.

A recent report released on Monday, reveals alarming trends in air quality, indicating that a person of color is 2.42 times more likely than a white person to live in a community that fails to meet pollution standards, with a staggering 3.9 million more people exposed to unhealthy ozone levels compared to the previous year. Will Barrett, assistant vice-president of the ALA’s Nationwide Clean Air Policy, criticized the EPA for weakening critical health protections, pointing to missed deadlines and rollbacks that allow increased emissions from oil and gas facilities. The report highlights that regions most affected by high ozone levels include southwestern states from California to Texas and much of the Midwest, with climate change exacerbating the situation by intensifying ozone pollution and increasing emissions from sources like datacenters.

A recent report from the American Lung Association reveals that 33.5 million children in the U.S., or 46% of those under 18, live in areas with failing air pollution grades, with about 152 million people breathing unhealthy air overall. The report, released on Monday, highlights that Los Angeles has the worst ozone pollution in the country, while Bangor, Maine, enjoys zero days of unhealthy ozone and short-term particle pollution. Climate change, along with extreme heat and drought, is intensifying ozone pollution, particularly affecting communities of color that face higher rates of chronic health conditions.
