Get the Lowdown on Low GWP

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 icon
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.
HFC icon
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.
Lower cases icon
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.

At Heatcraft, we're involved in key committees and working groups to help the industry develop standards for your operating location and your applications.

The low GWP landscape is rapidly evolving. For the latest information or questions, please contact Heatcraft at [email protected]

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:

  • 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.

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 took 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. Choose Heatcraft and choose the best partner for Low GWP.
