International Laboratory Freezer Challenge

The International Freezer Challenge is a friendly competition 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.

2019 Freezer Challenge Information

  • 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!
