Refrigerants account for 12 percent of our global GHG footprint, contributing nearly twice that of the fuel used in our trucks. As demand for our retail services expands globally, especially for fresh and frozen food, the need for refrigerated equipment will continue to grow. We’re committed to becoming more sustainable in this area, while working to ensure safe, reliable and affordable food to our customers around the world.
Our work in this area has driven a greater than 8 percent decrease in total annual GHG emissions from refrigerants in our 2005 base of stores and clubs. Furthermore, we continue to see the growth rate of our refrigerant emissions decrease at all our facilities, when compared to both sales and square footage. This suggests we’re using them more effectively than ever before.
We continue to produce results by applying industry best practices and by remaining committed to a refrigerant strategy that focuses on:
We continue to evaluate feasible alternatives to conventional refrigerants, from both a GWP and TEWI perspective. In November 2010, former President and CEO Mike Duke and others from the Consumer Goods Forum signed a resolution “to begin phasing out HFC refrigerants by 2015 and replace them with non-HFC refrigerants where these are legally allowed and available for new purchases of point-of-sale units and large refrigeration installations.”
In 2011, we began incorporating refrigeration and store designs that would enable the transition to less HFC-reliant systems. We’ve also begun testing full HFC-free systems in several markets. These experiments will allow us to validate system efficiency, total GHG impact and quality functionality.
