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 and how to be a sustainable buff at home, work, and play. RGS also helped achieve a record 91% diversion rate at the Buffs’ final home game against Arizona.

At the sustainability table, fans could take a pledge to reduce their environmental impact and play a

recycling game in order to win prizes like bamboo utensils, water bottles, t-shirts made from recycled

water bottles, and bike lights. Here an RGS student, Claire, and RGS program manager Angie hand out prizes.

of the waste from landfills, including 1,200lbs of bottles and cans for recycling and 1500lbs

of organic waste sent to a compost yard.
