International Laboratory Freezer Challenge
The International Freezer Challenge is a friendly competition co-sponsored by I2SL and My Green Lab designed to promote best practices for energy efficiency in cold storage management. Challenge winners are determined based on the amount of energy they save and can also earn points for sharing tips about their own cold storage best practices.
- The 2022 Freezer Challenge is now closed! Please check back soon to learn more about this year's winners.
- Participants earned points through various efficiency actions, such as temperature tuning, retiring or upgrading old freezers, cleaning out unneeded samples, implementing cutting-edge practices, and more. You could also earn points by sharing your own best practices with others.
- Winners will be featured in Lab Manager magazine and will be recognized at the I2SL Annual Conference in Pittsburgh, Pennsylvania, October 16-19, 2022.
Wondering how your fellow scientists implement cold storage best practices in a variety of lab environments? Hear from four panelists who have participated in My Green Lab and I2SL's Freezer Challenge. If interested in viewing the panel discussion, you can download the free recording here.

Congratulations to the 2021 Freezer Challenge winners! Despite the challenges presented by COVID-19, over 220 laboratories completed the competition, representing 113 different research institutions from around the world. This year's Freezer Challenge participants saved a combined 4.3 million kilowatt hours per year, more than any year previously. This is equivalent to reducing carbon emissions by 3,000 metric tons annually.
