The Environmental Investigation Agency (EIA) recently released a report that it says exposes Walmart and other major U.S. supermarkets leaking potent greenhouse gases into the atmosphere.
Leaking Havoc: Exposing Your Supermarket’s Invisible Climate Pollution is the result of a months-long investigation of dozens of supermarkets in the greater Washington, D.C. area, including Maryland and Virginia, that focused on detecting leaked refrigerant in refrigerated aisles. The investigation, using industry-accepted leak detector technology, found over half of all stores investigated to be leaking refrigerants. Using an infrared camera, EIA captured video showing HFCs leaking out onto products in an open refrigerated display case in a store.
EIA’s investigation, which focused on Walmart and other top-grossing supermarkets, showed that 60% of Walmart stores visited had an HFC refrigerant leak. Across all other stores investigated, more than half were measurably leaking these refrigerants. A few stores had high concentrations of HFCs still present months later.
The leakage of refrigerants can be avoided through proactive refrigerant management, stated EIA. In spite of the current lack of regulations on HFCs, the recently passed American Innovation and Manufacturing Act (AIM) Act authorizes EPA to regulate production, use, and emissions of HFCs.
“It’s alarming that today’s regulatory landscape still allows supermarkets to legally use and leak HFCs in massive quantities,” said Christina Starr, senior policy analyst at EIA. “With recent passage of the AIM Act, it’s high time for the EPA to design more effective regulations to accelerate replacement of HFCs with climate-friendly refrigerants and to require companies to monitor and mitigate leaks.”
