National Analysis Suggests Cutting Carbon Dioxide Would Improve Air Quality In Missouri

Cutting carbon dioxide emissions from power plants would also reduce other types of air pollution, both here in Missouri and nationally.

That's according to a recent analysis by researchers at Harvard and Syracuse Universities.

Along with carbon dioxide, coal-fired power plants emit other pollutants, like sulfur dioxide and nitrogen oxides. Those in turn can contribute to forming particle pollution, ozone, and smog.

A new report by the American Lung Association finds that the St. Louis metro area still

has high levels of ozone pollution, the main ingredient in smog.

The annual State of the Air report ranked St. Louis 13th out of 217 metro areas in the country for ozone pollution. That’s worse than St. Louis performed in last year’s report, although the trend over recent decades has been gradual improvement.

It’s a stretch to think about summer now. 

But close your eyes and imagine.

The sun is shining; bees are buzzing; your arms move through warm air; you even have to mop a thin veil of perspiration from your brow. And on the news in the morning, Geri Mitchell intones the familiar admonition: “It’s a red air quality day. Sensitive groups should avoid exercising outdoors.”

If you happen to be near the Saint Louis Science Center planetarium at around 2 o’clock in the afternoon, look up. You might see a weather balloon.

Students at Saint Louis University are launching them as part of a study sponsored by the U.S. space agency NASA.

The mission aims to improve our understanding of air pollution and global climate.

A report released today by the American Lung Association shows that air pollution in the St. Louis region has recently increased.

The annual report ranks the St. Louis area 12th worst among U.S. metropolitan regions for particulate pollution and 25th for ground-level ozone, the main component of smog.

Susannah Fuchs is the Senior Director of Environmental Health for the American Lung Association’s Plains-Gulf Region, which includes Missouri.

Warming temperatures may have you wanting to spend more time outdoors. But warm weather can mean more unhealthy air.

Susannah Fuchs of the American Lung Association says our region’s sunny, hot, nearly windless summer weather creates the perfect conditions for the formation of ozone – the main component of smog.
