By The #LeaveNoTrash University Challenge is a student-centered spinoff of the existing Leave No Trace #LeaveNoTrash campaign.
It’s a week-long event in April, designed to build a community of people who recognize the 7 Leave No Trace principles and apply them every place people live, work, and play, including college campuses and communities. This year, Cleanup Week is April 18-26, 2026.
