Tesco, one of the world’s largest supermarket chains, will convert more than 1 200 UK stores from R-404A to a low global warming potential (GWP) refrigerant. Over the next three years, the companies will replace R-404A with the HFO R-448A, which has a GWP of 1 273, making it the lowest-GWP refrigerant available today for supermarket refrigeration.
The change is predicted to reduce the retailer’s carbon footprint by up to 40 %. The first phase of the project has converted 60 stores to R-448A, which is a near drop-in replacement for R-404A. Tesco has publicly committed to reducing carbon emissions by 26.5 % compared to a 2006-2007 baseline.
