Hy-Vee won three awards from the U.S. Environmental Protection Agency for achieving voluntary goals to reduce refrigerant emissions. The EPA is running a GreenChill Partnership because leaky refrigeration units can be expensive and add to climate change by releasing greenhouse gases. “We applaud the supermarket chains for their environmental leadership in minimizing refrigerant emissions and their adoption of advanced refrigeration technologies,” said Anne Idsal, acting assistant administrator for the EPA’s Office of Air and Radiation. “They’re not just protecting the environment; they’re keeping costs down for themselves and their customers.”
