GreenChill is an Environmental Protection Agency (EPA) cooperative alliance with supermarkets, and chemical and refrigeration equipment manufacturers. The alliance is dedicated to promoting the use of retail food refrigeration technologies that reduce emissions of ozone depleting substances and greenhouse gases by both reducing refrigerant emissions and increasing refrigeration system energy efficiency. The program also asks supermarket partners to make several important commitments that go beyond regulatory compliance. The EPA estimates that widespread adoption of best practices, improved equipment design and service, and advanced refrigeration technologies could reduce refrigerant emissions by 1 million metric tons of carbon equivalent per year, which is the equivalent of taking 800,000 automobiles off the road, and save over $12 million in operating expenses.
