Profile of an Average U.S. Supermarket's Greenhouse Gas Impacts from Refrigeration Leaks Compared to Electricity Consumption NjxS3.o^ENTAL PR0TEcr,0/v GREENCHILL ^frigeration This is a profile of an average U.S. supermarket and the resulting Greenhouse Gas (GHG) impacts from leaked refrigerants and electricity consumption in a given year. The GHG estimates are based on the assumptions and industry information cited below and provided in pounds and metric tonnes of carbon dioxide equivalent (CC^eq). To calculate your specific store's GHG impact from refrigeration leaks and electricity consumption use the corresponding GreenChill calculator. U.S. Supermarket Store Size1 Annual Electricity Consumption Intensity for U.S. Supermarkets2 Annual Electricity Consumed (Annual Consumption Intensity x Store Size) Electricity Use Emission Factor (U.S. Average)3 Annual C02eq Emissions from Electricity Consumption Annual C02eq Emissions from Electricity Consumption (metric) 46,000 square feet 51 kilowatt hours per square foot 2,346,000 kilowatt hours per year 1.30 pounds of C02eq per kilowatt hour 3,049,800 pounds of CO2 per year 1,383 metric tonnes of CO2 per year Typical Commercial Refrigerant Used4 Global Warming Potential (AR4 standard)5 Commercial Refrigeration Charge Size6 Annual Commercial Refrigeration Leak Rate7 Annual Volume of Commercial Refrigerant Leaked Annual C02eq of R-404A Leaked Annual CO2 eq of R-404A Leaked (metric) R-404A 3,921.6 3,500 pounds 25% per year 875 pounds per year 3,431,400 pounds of C02eq per year 1,556 metric tonnes of C02eq per year 1 Food Market Institute, n.d.
