An introduction to the characteristics, nuances and applications of an emerging natural refrigerant.

Although the U.S. has seen steady increases in CO₂ adoption in recent years, it still hasn’t experienced the industry-wide acceptance taking place in Europe. But that appears to be changing.

Over the past several years, the dynamic regulatory landscape has influenced the selection of commercial refrigeration equipment for new and renovated facilities.

According to industry estimates that forecast the use of natural refrigerants over the next few years, the adoption of CO₂ (refrigerant name R-744) is expected to increase significantly in the U.S.

A refrigerant’s environmental sustainability is determined largely by its greenhouse gas emissions, which are measured by their ozone depletion potential (ODP) and global warming potential (GWP).

If you're a supermarket owner or operator, selecting a sustainable refrigeration strategy is imperative to your long-term success.

With regulations potentially varying from state to state, operators are attempting to make refrigeration equipment decisions that align with regional environmental mandates and operational objectives.

For the past several years, the state of California has led the charge in the development of environmental regulations in commercial refrigeration applications. Read our full article to learn more.
