MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) recognizes Clean Air Month every May, emphasizing the importance of clean air and the impact it has on our health and environment.

Over the last several decades, air quality across Wisconsin has significantly improved. In recent years, however, that trend has slowed. Recent rollbacks of federal emission control rules will make it even more difficult to achieve important emissions reductions and protect public health across the state.

One of Wisconsin’s highest air quality priorities continues to be addressing ozone nonattainment. Ozone exposure can lead to or worsen numerous health issues, especially for children, older adults and people with respiratory conditions. “Long-term nonattainment and exposure to elevated ozone concentrations is a public health concern,” said Gail Good, DNR air management director. “It also negatively impacts economic development in the state.”

For decades, Wisconsin has implemented statewide rules limiting ozone-causing emissions from power plants and other industrial sources, but resolving nonattainment is difficult because most emissions come from either out-of-state sources or from sources the EPA controls, like cars and trucks. Wisconsin sources are responsible for only about 10% of the ozone measured in nonattainment areas, while emissions from other states are responsible for about 50%.

The DNR is focused on science-based strategies to improve air quality and public health outcomes in the nonattainment areas by focusing on the emissions that are causing the problem. As the DNR continues to take on air quality challenges, there are ways you can contribute to improving air quality in your community. Driving fewer miles and using cleaner forms of transportation reduces emissions of many pollutants, including those that form ozone.
