Colorado had far fewer ozone alert days this summer than last, a Colorado media outlet is reporting.
The Front Range, which includes the Denver-Boulder area, Colorado Springs, Fort Collins and Greeley, saw 30 Ozone Action Alert Days between May 31 and Aug. 31 this year. Last year, the same time period had 52 alert days, Colorado Public Radio reports.
On alert days, residents are recommended to limit their driving and avoid refueling vehicles.
Denver-Aurora ranked 12th worst in the country for ozone pollution in an April study by the American Lung Association.
The issue has been a recent focus for Denver City Council, which has been considering a "pollution tax" on businesses, reasoning that the city's downward trend of gas emissions isn't enough to meet the levels that scientists say are necessary to combat climate change.
Gov. Jared Polis has also made air quality a priority in Colorado, recently signing an executive order Aug. 22 advising the Air Quality Council to act "boldly and cost-effectively" and prioritize mitigating climate change.
When the governor first took office, he issued an executive order to promote the use of electric vehicles, prompting the Colorado Air Quality Control Commission to require that automakers sell more qualifying vehicles each year.
Polis plans to have Colorado using 100% renewable energy by 2040, a goal that he says will not be deterred by President Trump directing the Environmental Protection Agency to ease regulations.
"It’s up to states like Colorado to drive bold solutions that will protect the health of our communities and address climate change," Polis said in a statement.
