International Laboratory Freezer Challenge Awards

As a CU Boulder lab participating in the Freezer Challenge, you're automatically helping the University of Colorado Boulder compete against other universities to take home the top awards! Awards are given to research institutions based on the total number of points and energy saved. "Organizational awards reward those research institutions that have encouraged many laboratories to make the greatest difference during this challenge" (Freezer Challenge FAQs). With your help, the University of Colorado Boulder could win the Organizational award for the Academia category.

Additionally, awards are also given to individual laboratories who score the most points per number of refrigeration units. Lab awards reckognize those labs who have made the greatest effort to improve their sample management and reduce the impact of their cold storage. 

Organization and Lab winners will have their names and photos published in Nature.
