The 2024 Challenge engaged over 3,000 labs and saved over 30 million kWh—highlighting the real-world climate impact of lab sustainability practices.

This year’s challenge demonstrated how simple lab actions can scale to massive environmental savings. Here’s what our global community accomplished together.
Total energy saved across all participating labs.
Greenhouse gas emissions avoided.
Participated globally across all sectors.
Organizations represented in the 2024 Challenge.
Participating cold storage units.
Equivalent gas-powered cars driven for one year with energy savings.
Award categories for the Freezer Challenge
While every participating lab is a winner for helping save an incredible amount of energy, we are proud to honor the below labs for their significant contribution to the Freezer Challenge.
kwh/day savings is not the only determinant of whether a lab or organization receives a top award or honorable mention. Many actions in the Freezer Challenge do not equate to energy savings – normalized points is the first factor looked at, then kwh/day saved.
Note: Winning Streak Awards are given to previous year’s winners that exceeded their energy savings from last year.
