how U.S. Supermarkets Can take Action to reduce the climate impacts of cooling
Technologies are available to phase-down HFCs by replacing them with low global warming potential (GWP) refrigerants and energy efficient designs. By installing best-in-class low GWP technologies in all new stores beginning in 2020, U.S. supermarkets can collectively avoid 20.8 million metric tons CO2e of HFC use by 2025. Converting existing stores to refrigerants with lower GWPs can also have a positive impact. Reducing average refrigerant GWP in all U.S. supermarkets by 50% would shrink refrigerant emissions in the U.S. by 22.7 million metric tons CO2e annually in 2025. More on technology adoption.
Refrigerant management strategies focus on avoiding refrigerant leaks and venting of refrigerants retired from systems at their end of life. Reducing leak rates to the GreenChill Partnership corporate average of 13% in all U.S. supermarkets can mitigate about 15.5 million metric tons of CO2e emissions annually in 2025. Destroying the HFCs retired from a single supermarket system containing 3,000 pounds of R-404A mitigates over 5,000 metric tons of CO2e. More on refrigerant management.
Technical & Policy Dialogue
Supermarkets can help overcome the remaining market barriers to widespread adoption of climate-friendly technologies and best practices in cooling by engaging with other industry stakeholders and policymakers. This includes participation in dialogue on standards and code development, supply chain availability, technician training and certification, and state and federal policy dialogue.
