Campus Sustainability Month on the University of Illinois campus expanded from Campus Sustainability Week, which was created to raise awareness of the University’s sustainability projects, celebrate the successes of those projects, and motivate more progress on the sustainability front. The first Sustainability Week was held October 25-29, 2010, and the event has been held every Fall semester since then. 

National Campus Sustainability Day is celebrated each year in late October. Campus Sustainability Day is a time to recognize the success, challenges, and innovations of sustainability in higher education.  It coincides with the national Campus Sustainability Day and Food Day, which are typically on Wednesday at the end of October.  In collaboration with many partners, iSEE hosts Campus Sustainability Month events each year, to include activities to educate and encourage the campus and community to go green! It is a celebration of the University's sustainable successes, and provide educational motivation to make even more progress. Participants visit the University's most sustainable sites, and watch intriguing presentations about environmental ideas.
