GWP (Global Warming Potential) is the EPA's measure of how much energy the emissions of 1 ton of gas will absorb over a given period, relative to 1 ton of carbon dioxide (CO2)
GWP is the new metric on which our industry is being evaluated. Basically, the lower the GWP, the less the refrigerant warms up the earth.
Passed in December 2020, The American Innovation in Manufacturing Act (AIM) authorizes the EPA to phase-down hydrofluorocarbon (HFC) production, restrict its uses, based on sector, and define refrigerant management standards.
Current regulations limit GWP thresholds to lower than 300, and in some cases, 150. Starting as early as Jan. 1, 2022, these new regulations are likely to continue through 2026 and beyond.
The key regulations likely to impact your business:
Ozone Depletion Potential (ODP) is out, GWP is in. It's the new standard by which all refrigerants are now measured, as you can see in this chart:
What refrigerants are Low GWP?
HFO refrigerants are made of organic compounds and have significantly lower GWP than their HFC counterparts.
NH3 or ammonia has a GWP of 0, the lowest of any product available. However, its toxicity may make it unsuitable for your business.
Propane satisfies Low GWP standards, but is highly flammable.

We'll analyze your facilities and determine the best course of action for Low GWP compliance, based on the intricacies of the regulatory requirements for your business needs, and more!
Did you know California passed a state regulation that imposes a limit of 150 GWP for new stationary refrigeration systems with greater than 50 lbs. of charge for new facilities? This law takes effect Jan 1, 2022. How could this regulation affect you? Let us help you navigate the complex regulatory landscape and what this law could mean for commercial cold storage across the U.S. and Canada.
Low GWP regulation doesn’t just apply to new installations. CARB (California Air Resources Board) and SNAP regulations offer specific language for handling retrofit applications in existing facilities. Are you replacing a complete refrigeration system, several systems or just a component? We can guide you on the requirements and options available to you.
Remove the risk of going it alone.
