WHAT ARE THE GOALS OF THE UNC FREEZER CHALLENGE?
1. Raise awareness about environmental impact of cold-storage 4

”
As former scientists, neither Allison nor myself ever once
thought about our lab refrigerators or -80°C freezers, aside from making sure they were still functional and that
samples remained where they were left

WHAT ARE THE GOALS OF THE UNC FREEZER CHALLENGE?1. Raise awareness about environmental
impact of cold-storage
2. Give scientists tools to use cold-storage efficiently
3. Reduce energy usage in labs across UNCGoal to have 100 labs participate
