Ultra-low temperature freezers consume as much electricity annually as a typical single-family home. Hopkins laboratories can lower their lab’s carbon footprint and challenge your cold storage practices by taking part in the Freezer Challenge. Supported by the International Institute for Sustainable Laboratories (I2SL) and My Green Lab, this challenge is designed to promote best practices in cold storage management for laboratories around the world.

The annual competition operates from January to July and the top Johns Hopkins winners will be awarded a cash prize. In addition, the overall winner of the international challenge will be featured in Nature magazine and awarded during the annual I2SL conference.
