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 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.

2021 Freezer Challenge Information

  • Registration for the 2021 Freezer Challenge is now open! Register online to receive your scoresheet and begin earning points for your cold storage energy savings. You can count any actions you’ve taken from August 1, 2020, until the July 1, 2021, deadline on your scoresheet.
  • Labs can receive points for implementing good management practices, retiring and upgrading old freezer units, temperature tuning, and more. Participants can also earn points for sharing their own cold storage best practices. Learn more about what you can do to earn points on the Freezer Challenge website.
  • Winners get their photo in Nature and will be recognized at the September 2021 I2SL Annual Conference.
  • Despite the challenges presented by COVID-19, 218 labs or sites participated in this year’s International Laboratory Freezer Challenge, representing 88 research organizations around the world. This year’s Freezer Challenge participants saved a combined 3.2 million kilowatt hours (kWh) of electricity per year. These energy savings helped reduce carbon emissions by 2,260 metric tons—the equivalent of removing 360 cars from the road for a year!
