TLDR :city_sunset:

This article examines the most polluted cities in the United States, focusing on fine particulate matter (PM 2.5) pollution levels. It highlights the economic and health impacts of air pollution, and discusses efforts to improve air quality.

Key Points :key:

  • The top 21 most polluted cities in the U.S. are identified, with 6 of the top 7 located in California.
  • Air pollution can have significant economic impacts, including reduced worker productivity, increased healthcare costs, and impacts on consumer and investor decisions.
  • The EPA has found that the benefits of the Clean Air Act far outweigh the costs, providing $2 trillion in benefits between 1990-2020.

In-depth Summary :memo:

The article begins by discussing the global impact of air pollution, which the World Health Organization estimates is responsible for 7 million deaths annually and could cost the global economy $18-25 trillion per year by 2060. With predictions that 70% of the world’s population will live in urban centers by mid-century, cities are on the frontlines of the fight for cleaner air.

The article then presents data from the American Lung Association’s 2024 “State of the Air” report, which ranks the 21 most polluted cities in the U.S. based on annual average PM 2.5 concentrations. Six of the top seven cities are located in California, with four in the state’s Central Valley region. This is due to the valley’s geography, which traps pollution from coastal population centers.

The article also discusses the economic impacts of air pollution, including reduced worker productivity, increased absenteeism, and higher healthcare costs. However, it also highlights the economic benefits of improving air quality, citing an EPA study that quantifies the benefits per metric ton of particulate matter reduced across various sectors.

Finally, the article touches on the impact of air quality on businesses, noting that it can influence employee retention, healthcare costs, and consumer/investor decisions. It also discusses the EPA’s recent $2 billion settlement with engine manufacturer Cummins, highlighting the regulatory stick that can be used to drive air quality improvements.
