Waitrose has recorded a 6.6 percent average energy saving, with as much as 9 percent saved on the high temperature systems, in the first installation of R-449A in a United Kingdom (UK) supermarket.
In 2010, Waitrose published its Carbon Plan, based on an absolute operational emissions target of 15 percent carbon dioxide equivalent (CO2e) reduction. The indirect and direct emissions from the refrigeration systems in its shops are a very significant contributor, making this area a prime target for improvement.
