Cold storage units are mainstays of life sciences labs, yet few consider their environmental and cost implications. Just one ultra-low temperature freezer consumes as much energy as a typical single-family home. In 2017, two non-profits, the International Institute for Sustainable Laboratories and My Green Lab, launched the Freezer Challenge to promote and share sustainable cold storage practices. Now the International Laboratory Freezer Challenge, hundreds of labs now participate each year and serve to inspire savings in many, many more.
Laboratory refrigeration requires a surprising amount of energy. Since 2017, the International Laboratory Freezer Challenge has pushed labs to reduce their draw.
My Green Lab and the International Institute for Sustainable Laboratories (I2SL) teamed up for the fourth year to foster competition between research institutions and encourage best practices with laboratory cold storage, including energy efficiency.
