Air Quality in the Sacramento Region

Let’s share the bad news first. The Sacramento Region remains high on the list of the most polluted metropolitan areas in the nation and our air quality continues to adversely affect the health of our communities, especially our children and elderly. Now, the good news! We are making strides towards cleaning our air through our local clean air programs, with the help of our partners, sponsors, and volunteers. We also support our partners and other organizations that are also working to improve air quality in our communities.

Understanding the Air Quality Index (AQI)

The purpose of the Air Quality Index (AQI) is to help you understand what local air quality means to your health. The higher the AQI value, the greater the level of air pollution, which means the greater the health concerns. It’s an easy way to determine if you can enjoy the outdoors as usual or if you should consider planning an indoor activity to reduce exposure to polluted air. The Air Quality Index assigns a color to the day’s air quality ranging from good (green) to very unhealthy (purple).
