Survey highlights

• In the last year, direct emissions from leaking refrigeration gases have been reduced by more than 120,000 tonnes of CO₂ equivalent – and that doesn’t include reductions from Sainsbury’s and Aldi¹
• Waitrose’s new climate-friendly refrigeration made significant savings in both energy and costs.  In one store, it managed to reduce its refrigeration carbon footprint by a whopping 69 per cent, and the company has committed to be completely HFC-free by 2020 
• Tesco now has HFC-free refrigeration in 46 stores across the UK and is introducing this technology in overseas stores too.  It’s also the first retailer to embrace doors for food refrigeration, with 265 express stores due to be fitted by April 2011 and a further 200 stores planned in 2011
• Sainsbury’s was the first retailer to commit to CO₂ technology in all new stores, and has increased its 2014 target for rolling out this technology from 135 stores to 250
• Marks and Spencer has made significant reductions in the leakages from its equipment, and despite currently using hybrid systems containing small amounts of HFCs, has pledged that all new stores will have totally HFC-free refrigeration
• The Co-operative Group and Morrisons have committed to using HFC-free systems in all stand-alone refrigeration. Lidl has committed to using HFC-free technology in all freezer cabinets and in all new distribution centres, and Iceland is finally trialling HFC-free equipment
