RefrigeratorsMost domestic refrigerators are transitioning from HFC134a refrigerant (which has thousands of times the global warming potential of CO2) to climatefriendly refrigerants like R600a. In addition to being more energy efficient, these refrigerators are also typically much quieter!
To develop the following list of products, we started with the Energy Star Most Efficient refrigerator product list, then screened for those with climatefriendly refrigerants. Not finding what you're looking for? Then check out this longer list of hundreds of additional Energy Star qualified refrigerators that use lowGWP refrigerants (last upload: November 2020). Please contact us if you know of additional refrigerators you think should be added to this list.
