Air Quality

Improving our local environment benefits everyone in our community and makes Louisville a better place to live. As a community, we face an uncertain environmental future that requires us to make bold, innovative steps to reduce the harm human activities cause to the natural world. We will help our agencies make progress on our community’s air quality goals by working with them to pilot and scale innovative technology and data products.
We will be successful when…
When Louisville’s air quality is no longer a risk to our community’s health


  • Reduce emissions on Smart Corridors
    • % reduction in emissions on corridors with upgraded traffic technology
  • Increase adoption of alternative fuel vehicles
    • % of alternative fuel vehicles in LMG Fleet
  • Make Louisville a test bed for innovative air quality monitoring
    • # of innovative air quality monitoring techniques & technologies pioneered in Louisville


AIR Louisville is the first-of-its-kind data-driven collaboration among public, private and philanthropic organizations to use digital health technology to improve asthma. Propeller Health and the Institute for Healthy Air, Water and Soil are leading the program with support from the City of Louisville, the Mayor's office and the Louisville Metro Department of Public Health and Wellness.
In addition to local Louisville residents, a coalition of seven employers, three healthcare providers, a health plan and three advocacy groups have committed to enrolling patients, members, dependents, and employees. The program includes local employers Brown-Forman, Humana, Kindred Healthcare, Metro Louisville employees, Papa John’s, Seven Counties, WHAS11, healthcare providers including Family Allergy & Asthma, JenCare, and University of Louisville Pediatrics, and Passport Health Plan.

Connection 21

This project is updating the transportation technology at 114 intersections covering 6 suburban corridors. The deployed technology, fiber-optic cable and 2070 traffic signal controllers (computers that run traffic signal timing) will give our Traffic Engineers improved ability to communicate with the signals and modify signal timing. Additionally, the new traffic signal controllers could act as a hub for smart devices like Connected & Autonomous Vehicles (CAV) and air quality monitoring to help us understand transportation’s impact on the immediate environment. This is the first step towards Louisville creating a comprehensive Intelligent Transportation System (ITS) that will help us reduce the impact of transportation on our local air quality.
