In the 2021 Freezer Challenge, 222 labs participated from over 100 different research institutions across 17 countries. The combined efforts of the scientists and labs saved 4.6 million kWh of electricity over the past year, which is the equivalent of reducing carbon emissions by 3,260 metric tons. 

Based on the U of I's submitted scoresheets (33 in total), the combined actions of the university saved a total of 1051 kWh/day across multiple labs throughout campus.
