Ralphie’s Green Stampede, a partnership between the CU Environmental Center, CU Athletics, and Facilities Management, completed another successful basketball season. Ralphie’s Green Stampede had student volunteers at over 20 men's and women's basketball games in the 2021-2022 season. Volunteers educated Buffs’ fans about zero waste, how to be a sustainable buff, and achieve a record 91% diversion rate at the Buffs’ final home game against Arizona.
