National Campus Sustainability Day will take place from 11 a.m. to 2 p.m. Thursday in the free speech zone at Iowa State. The event is free to attend.

About 30 organizations from the ISU and Ames community, including the GreenHouse Group, ISU Bike Share, Team PrISUm and The Green Umbrella, will host the event. All of these businesses and groups participating in the event will be sustainability-minded organizations.

National Campus Sustainability Day, which is running under the theme “Campus as Catalysts,” will allow these groups to promote themselves as well as provide an opportunity for students to learn how to go green in their daily lives.

Free bike tune-ups will be available, as well as free cookies. Students can get free hot beverages by bringing their own mug from home or have the chance to earn a reusable mug at the event, according to the Iowa State Office of Sustainability

The event is sponsored specifically by the ISU Office of Sustainability and the Green Umbrella Club, a nonprofit dedicated to sustainability, in honor of National Campus Sustainability Month.
