Lowest Global Warming Potential Refrigerators And Freezers

Many refrigerants — the material in a freezer or refrigerator that are used to create a cooling effect — are harmful to the Earth’s atmosphere. As a result, they are labeled as having high “Global Warming Potential” or GWP.

Low GWP freezers and refrigerator do exist and can be spefically shopped for. These appliances usually used R-600a or R-441A refrigerants.

GWP ratings vary depending if you are looking at the number for the 25-, 50-, or 100-year impact of that material on the atmosphere. Lower numbers are better, so an ideal number would be 0, but ratings of 3 an under are considered good.

The common, but outdated, refrigerant called R-22 is a type of hydrochlorofluorocarbon. It’s sometimes labeled as HCFC-22 and has a GWP rating of about 1800 (100-year rating). On the other side of the spectrum there are substances like refrigerant grade ammonia (R-717) which has a GWP of 0, marking a vast improvement.

R-600a, or Iso-Butane, is an increasingly popular refrigerant 2022 thanks to its affordable price and low GWP (about 3). R-600 is commonly found in residential and small commercial refrigerators, freezers, water coolers, and drink dispensers.
