The International Freezer Challenge

The NIH Freezer Challenge is modeled after the International Freezer Challenge, run by the non-profit organizations My Green Lab and the International Institutes of Sustainable Laboratories (I2SL). The International Freezer Challenge is an annual competition where labs compete to see who can reduce the most energy consumed by the freezers in their labs. The NIH won the 2020 International Freezer Challenge in the government organization category. Additionally, the NCI Laboratory of Cell Biology won the 2020 International Freezer Challenge in the individual government laboratory category. Help us become repeat winners by participating in the 2021 freezer challenge.
