International Laboratory Freezer Challenge

2023 Freezer Challenge Information 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.

  • Take the 2023 Freezer Challenge and start saving in your lab! Register online to receive your scoresheet and begin earning points for your cold storage energy savings. All scoresheets are due by July 1, 2023.
  • Participants can earn 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 can 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 2023 Annual Conference.

Congratulations to the 2022 Freezer Challenge winners! Over 1,200 labs from 27 countries and over 12,000 cold storage units participated in this year's challenge. Participants saved saved a total of 9.5 million kilowatt hours of energy—equivalent to the energy consumption of over 1,300 homes for one year! These savings also helped prevent 6,732 metric tons of carbon dioxide from being released. Since its inception in 2017, the International Freezer Challenge has saved 24 million kWh of energy.
