The American Lung Association’s 2019 “State of the Air” report revealed that Springfield’s ozone pollution got worse since last year’s report. The 20th annual report found that Springfield had a weighted average of 1.0 unhealthy ozone days between 2015-2017, which is higher than the average of .3 unhealthy days from last year’s report. 

“Springfield residents should be aware of unhealthy air quality days, which are largely caused by hotter days and vehicle emissions,” said Angela Tin, national senior director for clean air initiatives for the Lung Association. “In addition to challenges here in Springfield, the 20th-anniversary ‘State of the Air’ report highlights that more than four in 10 Americans are living with unhealthy air, and we’re heading in the wrong direction when it comes to protecting public health.”

The annual “State of the Air” report tracks Americans’ exposure to unhealthful levels of ozone or particle pollution, both of which can be deadly. This year’s report covers the most recent quality-assured data available collected by states, cities, counties, tribes and federal agencies in 2015-2017. Notably, those three years were the hottest recorded in global history. 

Each year the “State of the Air” provides a report card on the two most widespread outdoor air pollutants, ozone pollution, also known as smog, and particle pollution, also called soot. The report analyzes particle pollution in two ways: through average annual particle pollution levels and short-term spikes in particle pollution. Both ozone and particle pollution are dangerous to public health and can increase the risk of premature death and other serious health effects such as lung cancer, asthma attacks, cardiovascular damage, and developmental and reproductive harm.

Ozone Pollution in Springfield

  • Grade: C
  • Rank: 110th most polluted 
  • 1.0 unhealthy ozone days

Compared to the 2018 report, Springfield experienced more unhealthy days of high ozone in this year’s report. However, this is a significant improvement from the 2016 report, where the area had 4.3 unhealthy ozone days.

“Ozone especially harms children, older adults and those with asthma and other lung diseases,” said Tin. “When older adults or children with asthma breathe ozone-polluted air, too often they end up in the doctor’s office, the hospital or the emergency room. Ozone can even shorten life itself.” 

This report documents how warmer temperatures brought by climate change make ozone more likely to form and harder to clean up. This year’s report showed that ozone levels increased in most cities nationwide, in large part due to the record-breaking global heat experienced in the three years tracked in the report. 

Particle Pollution in Springfield

  • Short-Term Particle Pollution
    • Grade: A
    • Rank: One of the cleanest cities
    • Zero unhealthy air quality days
  • Year-Round Particle Pollution
    • Grade: Pass
    • Rank: 104th most polluted

The 2019 report also found Springfield had the lowest levels ever for year-round particle pollution.

“Particle pollution is made of soot or tiny particles that come from coal-fired power plants, diesel emissions, wildfires and wood-burning devices. These particles are so small that they can lodge deep in the lungs and trigger asthma attacks, heart attacks and strokes, and can even be lethal,” said Tin. “Year-round particle pollution levels have dropped thanks to the cleanup of coal-fired power plants and the retirement of old, dirty diesel engines.”

While the report examined data from 2015-2017, this 20th annual report online provides information on air pollution trends back to the first report. Learn more about Springfield’s rankings, as well as air quality across Illinois and the nation, in the 2019 “State of the Air” report at
