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.

2023 Freezer Challenge Information

Congratulations to the 2023 Freezer Challenge winners! Nearly 2,000 labs from 27 countries and over 26,000 cold storage units participated in this year's challenge. Participants saved saved a total of 20.7 million kilowatt hours of energy—equivalent to 37.5 million miles driven by an average gas-powered vehicle! These savings also helped prevent over 14,600 metric tons of carbon dioxide from being released. Since its inception in 2017, the International Freezer Challenge has saved 44.7 million kWh of energy.
