For the second year running ATMOsphere America - The Business Case for Natural Refrigerants, included a lively end user panel featuring leading North American retailers. This year, representatives from Whole Foods, Sprouts, Delhaize America, SUPERVALU and Sobeys, shared their experiences in the use of natural refrigerants. The biggest change since last year: CO₂ transcritical has made it to the US.

Chaired by Keilly Witman from EOS Climate, formerly of the GreenChill Partnership, ATMOsphere America 2013’s end user panel looked at progress made by retailers in the use of natural refrigerants, the challenges faced, and their plans for the future. Over the last 12 months many of the retailers have made significant investments in CO₂ refrigeration. For example Sobeys currently has 45 CO₂ transcritical stores, with another 20 coming online in 2013. Whole Foods has a CO₂ transcritical system in construction on the East Coast, and one in the design stage planned for the West Coast, whilst the first Delhaize CO₂ transcritical store opens in July.


"Very pleased to see transcritical systems being piloted in the US because that is where the bigger market is. Once these pilots get going and other commitments are made, I think between now and next year we are going to see some huge leaps forward”, Rod Peterson, Sobeys.
