CO2 refrigerant gains in popularity as an ozone-friendly alternative

(Before It's News)

Commercial refrigeration unitThe U.S. Environmental Protection Agency has approved additional hydrocarbon refrigerants to be used in everything from cars to industrial refrigeration that are considered safe for the environment and “ozone friendly.” Meanwhile, carbon dioxide (CO2) is growing in popularity as an alternative refrigerant that is both natural, abundant, and inexpensive.

This final step of the EPA’s ongoing Significant New Alternatives Policy (SNAP) to approve alternative refrigerants that won’t harm the ozone and have a low global warming potential includes four new substances. This is part of President Obama’s Climate Action Plan, spearheaded by the EPA’s chief administrator Gina McCarthy.

Even with the addition of these new Earth-friendly refrigerants, the EPA still encourages manufacturers to choose carbon dioxide (CO2) when feasible due to it having an extremely low global warming potential, is non-combustible, and is ozone friendly.
