At the ATMOsphere Asia 2014 conference on natural refrigerants held in Tokyo, Japan, on 3-5 February, it was demonstrated by system manufacturer Panasonic and Japanese retailer Lawson that energy savings between 10-21% are achieved for a CO₂ transcritical system in the subtropical climate of Okinawa, Japan. In early 2014, Indonesia will see the opening of the first pilot CO₂ transcritical store by Lawson as well as an installation of Mayekawa’s NH₃/CO₂ NewTon in a cold store.
