Marks and Spencer PLAN A and experiences with alternative refrigerants

M&S adopted the Plan A strategy in 2007 setting out sustainability commitments. From 100 commitments Plan A was extended to include 180, to be achieved by 2015. Every year M&S publishes the document “How We Do Business” reporting on progress towards targets. Commitment 10.15 states that from 2010 all new installations will use CO2 secondary systems wherever possible and M&S should reduce GHG emissions from refrigeration by 50%. M&S is investing in “learning stores” to evaluate available technologies. For example at Ecclesall Road the refrigeration system is a hybrid a CO2 pump distribution system cooled by a primary hydrocarbon system.
