Refrigerant Management 


Reducing Leaks

By employing best practices to prevent, detect, and repair leaks, retailers can reduce their corporate leak rates from the sector average of 25% down to less than 10%. Reducing refrigerant leaks rates to the EPA’s GreenChill Partnership corporate average of 13% across the entire sector can reduce annual US emissions by 15.5 million metric tons of CO2 equivalent in 2025, while also reducing costs. The average supermarket participating in EPA’s GreenChill Partnership saves $2,400 per store each year due to reduced servicing and refrigerant costs. Following best practices in refrigerant management and servicing including reducing leaks can also improve energy efficiency significantly, curtailing up to half of the reduction of performance of equipment over its lifetime.

Leading supermarkets can:

  • Join EPA’s GreenChill Partnership

  • Set targets and strategies to achieve an average corporate leak rate under 10%

  • Install automated leak detection on large refrigeration systems or conduct regular inspections

  • Use software or other electronic system for tracking refrigerant use, leaks, and repairs 

Reclamation and Destruction

Leading supermarkets should ensure all refrigerants removed from systems are properly recovered and either reclaimed or destroyed, in order to avoid refrigerants being vented into the atmosphere at their end of life. Destroying HFCs retired from a single supermarket system containing 3,000 pounds of HFC-404A at end of life mitigates over 5,000 metric tons of CO2 equivalent emissions.

Leading supermarkets can:

  • Work with vendors to ensure all refrigerant recovered from systems is either reclaimed or destroyed

  • Ensure servicing technicians are trained in proper recovery techniques

  • Identify opportunities for incentives to destroy refrigerants such as voluntary carbon offset protocols
