Refrigerant regulations are another reason why change is coming, as HCFCs will be phased out by 2020, and given their high global warming potential (GWP), HFCs will likely be phased down in the near future as well. At some point, supermarkets will need to start considering low GWP alternatives such as HFO blends, as well as so-called “future-proof” refrigerants such as ammonia, CO2, or propane.

The conference offers an opportunity for leaders of the food retail industry and their business partners to discuss new refrigeration technology, energy-efficiency, and conservation, as well as refrigeration system and store design.

The coalition charges that EPA violated the federal Clean Air Act when it effectively rescinded regulations prohibiting the use of HFCs through guidance, rather than a public rulemaking process.

The U.S. Climate Alliance has made substantial progress toward the implementation of its commitment to uphold its share the Paris Agreement. Sixteen states and Puerto Rico continue to be on track to collectively meet their share of the U.S. climate target to reduce emissions by 26 to 28 percent from 2005 levels by 2025.
