The first U.S. supermarket to address climate-forcing HFCs (hydroflourocarbons) is in Maine in the tiny town of Turner.
Belgium-based Delhaize America, which owns the Hannaford supermarket chain, opened the first store that chills and freezes foods using carbon dioxide instead of super-greenhouse gas HFCs.
Carbon dioxide is a natural refrigerant used in Canada and Europe in moderate-to-cold climates.
Just using this system will cut the store's carbon footprint by 3.4 million pounds a year. Delhaize's goal is to lower greenhouse gas emissions 20 percent by 2020.
