What's happened
The American Lung Association's 2025 'State of the Air' report reveals a significant rise in Americans exposed to unhealthy air, with 25 million more people affected compared to last year. The report highlights worsening ozone and particulate pollution, particularly due to climate-related events like wildfires and extreme heat.
What's behind the headline?
Key Findings
- Rising Pollution Levels: The report indicates that over 156 million Americans live in areas with unhealthy air, a stark increase of 25 million since the previous year.
- Geographic Shift: While California remains a pollution hotspot, the report notes a troubling shift in air quality issues towards the eastern U.S., driven by factors like wildfires and extreme weather.
- Disproportionate Impact: Communities of color are disproportionately affected, with Hispanic Americans nearly three times more likely to live in areas with failing air quality grades.
Implications
- Policy Challenges: The report warns that proposed cuts to the Environmental Protection Agency (EPA) under the Trump administration could exacerbate air quality issues, undermining decades of progress.
- Health Risks: Increased exposure to ozone and particulate matter is linked to serious health conditions, including respiratory and cardiovascular diseases, raising concerns about public health outcomes in the coming years.
Future Outlook
- Climate Change Effects: As climate change continues to drive extreme weather patterns, the frequency and severity of air quality issues are expected to worsen, necessitating urgent policy responses and community action.
What the papers say
According to the New York Times, the American Lung Association's report highlights that 'the biggest thing that has saved patients’ lives in regard to lung health... is the Clean Air Act.' This underscores the importance of regulatory frameworks in improving air quality. Meanwhile, Bloomberg notes that 'the number of Americans exposed to high levels of these pollutants has risen by about 25 million since last year’s report,' indicating a significant regression in air quality.
The Independent emphasizes the alarming trend of worsening air quality, stating that 'nearly 25 million more people are breathing unhealthy air compared with last year’s report.' This stark increase is attributed to climate-related factors, including wildfires and extreme heat, which have shifted pollution patterns across the U.S. The report serves as a clarion call for renewed efforts to protect air quality, particularly as the Trump administration's policies threaten to roll back environmental protections.
How we got here
The report analyzes air quality from 2021 to 2023, a period marked by severe wildfires in Canada and ongoing climate challenges. Despite past improvements in air quality due to regulations like the Clean Air Act, recent trends show a troubling increase in pollution levels.
