Supporting the Use of Natural Refrigerants


Natural refrigerants— including carbon dioxide, hydrocarbons, and ammonia—are sustainable alternatives to commonly used hydrofluorocarbon (HFC) refrigerants. They have zero or near-zero global warming potential (GWP) and can decrease energy, gas, and water consumption while also permanently reducing greenhouse gas emissions from refrigeration.

However, supermarkets and other end users face a range of barriers when shifting to natural refrigerants, such as high upfront costs, a shortage of workforce training, and a lack of performance data. This collection of resources provides information on the applicability, technical considerations, and benefits of using natural refrigerants in place of traditional HFC refrigerants in order to support the widespread adoption of natural refrigerants.
