GWP 150 refers to refrigerants with a Global Warming Potential of 150 or lower, representing low-impact alternatives to high-GWP substances. These refrigerants meet EPA regulations under the Significant New Alternatives Policy (SNAP) and support compliance with the Kigali Amendment to the Montreal Protocol. GWP 150 refrigerants include HFOs like HFO-1234yf and HFO-1234ze.
Technical Specifications
A refrigerant’s GWP measures its climate impact over 100 years compared to CO2 (GWP = 1). GWP 150 refrigerants have minimal warming potential, making them suitable for new equipment installations. Common examples include HFO blends certified for commercial and light commercial applications, with zero ozone depletion potential (ODP).
Regulatory Compliance
EPA SNAP regulations increasingly favor GWP 150 or lower for most applications. The 2015 Kigali Amendment requires participating nations to phase down HFCs by 80 percent by 2047. GWP 150 compliance positions HVAC systems for current and future environmental standards while reducing long-term regulatory risk.
