Critical Issues — Air Quality and Respiratory Health
As Boulder County residents, we cherish the outdoors. But unfortunately, we don’t have clean air in our county, particularly in the summer, when outdoor recreation is at its peak. In recent years, the American Lung Association Report Card gave Boulder County an “F” due to unhealthy levels of ground-level ozone, a lung-burning pollutant that contributes to asthma and other respiratory diseases, which are a major risk factor for severe illness or death from COVID-19.
Ozone is formed during Colorado’s famously sunny days when the sun “cooks” volatile organic compounds and nitrogen oxides – air pollutants from vehicles and industry, including oil and gas. Boulder County and Boulder County Public Health are fighting to uphold the air quality rules we need to clean up our air and protect our climate.
