My Green Lab and the International Institute for Sustainable Laboratories (I2SL) are proud to announce that the 2022 Freezer Challenge has saved a total of 6,732 metric tons of carbon dioxide, which is equivalent to the energy consumption of 1,310 homes for one year, more than doubling the carbon reduction from last year’s competition!




It's our pleasure to share with you the video that we put together featuring the impact of the Freezer Challenge and many testimonials from the 2021 Freezer Challenge winners!

We are proud to announce that our My Green Lab Certification has been selected as a key indicator of progress for the United Nations Climate Change's High Level Climate Champions 2030 Breakthroughs Race to Zero campaign!

Hello again from the International Freezer Challenge! Today we bring you an inspiring story from a group participating in this year's competition: the Sanofi Pasteur R&D group in Cambridge Massachusetts. They reached out to us and wanted to share the progress they've made this year, and we hope this will inspire you to continue dedicating time and energy to the Freezer Challenge and laboratory sustainability efforts more generally.

This year's International Freezer Challenge now has over 150 labs from 18 different countries participating in this year's competition. Amazing!
