Earthfest, U-M’s fall event celebrating sustainability initiatives across the university, returned to the Diag on Sept. 22. It featured 40 student organizations, university units and local nonprofits sharing opportunities to learn about and get involved in sustainable operations, environmental advocacy, research and environmental justice. Earthfest serves as a touchstone for the U-M community to convene around efforts to achieve universitywide carbon neutrality and foster a shared culture of sustainability.
