​​​Clean, healthy air is critical to ensuring our health and community vitality. Research has linked air pollutants such as ozone and particulate matter to lung and heart disease, increased asthma rates, and other health problems. In our community, the major sources of these air pollutants include emissions from internal combustion engines (i.e., tailpipe emissions from cars), emissions from power plants, and emissions from indoor and outdoor appliances that ​run on fuels such as natural gas, diesel, propane, and gasoline. In addition, climate change is negatively impact air quality by causing more extreme heat days which both drive up cooling needs (and power plant emissions) and create the conditions for the formation of ground level ozone. Climate change is also leading to more wildfires and the associated increase in particular matter and more

​Air ​Quality Monitoring

Kerrytown_AQM.jpgIn order to monitor our community's ambient air quality, OSI is installing a network of air quality monitors across the city. So far, we have installed three of these monitors: one ​at the Kerrytown Farmer's Market; one at the intersection of Main Street and Washington Street; and one at Bryant Community Center. Additional monitor installations are planned for 2022 and 2023!

These solar-powered air quality monitors measure pollutants such as particulate matter (PM), carbon dioxide (CO2), ​​ozone (O3), ​nitric oxide (NO), nitrogen dioxide (NO2), ​carbon monoxide (CO), and sulfur dioxide (SO2). These pollutants, when at high enough concentrations, all have negative impacts on both human health and the environment. By monitoring concentrations of these pollutants in our air, we can be alerted to potentially harmful concentrations of the pollutants and gather data on the source of these high concentrations.

All of the data gathered by this network of monitors will be made publicly available. Please keep an eye out on this webpage for updates, information on how to download the data, and links to maps showing live pollutant concentrations at each monitoring site. These tools are currently in development and will be available soon!​ Please note that while the data provided by these sensors is monitored for accuracy, it is not EPA reference data.

​IDLE Free Ann Arbor

Did you know that vehicle idling constitutes 1.6% of all U.S. greenhouse gas emissions, double the total emissions from the steel and iron manufacturing in the country? This is partly why, effective July 1, 2017, Ann Arbor has an anti-idling ordinance​. This ordinance specifies that:

  • Commercial vehicles have a 5-minute idling limit city-wide and no idling while vehicles are unoccupied.
  • Non-commercial vehicles have a 5-minute idling limit in signed "No Idling" zones and no idling while vehicles are unoccupied. 

*The ordinance does not impact cars on residential property or in driveways. 

For violations of the ordinance, citations can be issued. If you observe a violation of the ordinance, please immediately ​report the violation by contacting Community Standards at 734-794-6942 or dispatch at 734-994-2911, so that an officer may be sent to the site to confirm the violation.

Do Your Part

1. Turn your engine off.  Whe​ther you're picking up your child from school or using the ATM, turn off your engine if you're stopped for longer than ten seconds.

2. Reduce warm-up idling. Experts agree modern engines require only a short idle period after engine start—even in very cold temperatures. Driving slowly for the first mile or two is the best way for the car to warm up.  Long idling periods can harm your engine and waste gas.

3. Spread the word.  Most people idle out of habit.  Encourage your family, friends and neighbors to help protect children's health, the environment, and save money by turning off their vehicles. 

Electrification

A key piece of A2ZERO (Strategy 2) focuses on mass electrification of buildings, appliances, and vehicles. This initiative is just beginning but is designed to improve indoor air quality, comfort, and safety, all while reducing local and regional greenhouse gas emissions. If you're interested in learning more about the City's efforts to electrify, please visit www.a2gov.org/electrify

​​Indoor Air Quality Testing

​Frequent testing of indoor a​​ir and water quality is important to ​our health and safety. For more information on how to test for air and water pollutants - as well as other dangerous substances - in your home, check out this guide​ from ​​the Safety, Health, and Consumer Council and ​SafeHome.org.
