About GreenChill
Launched in 2007, GreenChill is an EPA voluntary partnership program that works cooperatively with the food retail industry to lower refrigerant emissions, protect the ozone layer, and address climate change.
Food retailers, including supermarkets, grocery stores, co-ops, supercenters, and wholesale clubs, use commercial refrigeration systems throughout their stores to keep products cool. The commercial refrigeration systems typically used in these stores can leak harmful refrigerants into the atmosphere and those refrigerants can deplete the Earth’s ozone layer and contribute to climate change.
The GreenChill Advanced Refrigeration Partnership program works to help food retailers:
- Transition to refrigerants with zero ozone depletion potential and low global warming potential
- Lower refrigerant charge sizes
- Eliminate refrigerant leaks
- Implement best environmental practices
- Adopt advanced refrigeration technologies.
The GreenChill Partnership has three main programs:
- The Corporate Emissions Reduction Program: Partners with food retailers, refrigeration system manufacturers, and chemical producers.
- The Store Certification Program for Food Retailers: Recognizes individual stores for using environmentally friendlier commercial refrigeration systems based on rigorous criteria.
- The Advanced Refrigeration Promotion Program: Promotes the use of advanced refrigeration technologies, strategies, and practices.
