About the Festival

The Ann Arbor Earth Day Festival is an annual celebration coordinated by the Ann Arbor Earth Day Festival Planning Committee, a coalition of local environmental nonprofits and agencies, and will be held this year at Leslie Science & Nature Center.

This free, family-friendly event features displays; hands-on activities; live entertainment; green building and commuting technologies; energy topics; water awareness; sustainable agriculture; and more.

In the true spirit of Earth Day, this festival will be a Zero Waste event. Visitors can help keep up the average of 90% waste diverted from landfills during the Earth Day Event by bringing their reusable water bottle, and putting their waste in the right receptacles.

Special Presenters

Pop-up clothing swap - Leslie Science & Nature Center Energy House

Join Ann Arbor’s Office of Sustainability for a special pop-up clothing swap to refresh your wardrobe, without contributing to the massive climate impact of the fashion industry by buying new. You can also gift your gently used clothing to give them a second life and help build a community around reuse.

How it works: Each person can bring up to 10 items of clothing in good condition (no rips, holes, stains, or unwashed items, please!). Accessories such as bags, jewelry, and belts are also welcome. You can take clothing without bringing anything or bring clothing without taking anything.

To celebrate Tree Town's many amazing trees during the Earth Day Festival, OSI will also provide a self-guided tree walk at Leslie Science and Nature Center! We hope that these walks will help connect you with our urban trees and their place in making Tree Town more sustainable.
