Refrigerants - Environmental Properties

Refrigerants - Ozone Depletion (ODP) and Global Warming Potential (GWP).

Common refrigerants and their Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) are indicated below.

  • Ozone Depletion Potential (ODP) of a chemical compound is the relative amount of degradation  it can cause to the ozone layer
  • Global Warming Potential (GWP) is a measure of how much a given mass of a gas contributes to global warming. GWP is a relative scale which compares the amount of heat trapped by greenhouse gas to the amount of heat trapped in the same mass of Carbon Dioxide. The GWP of Carbon Dioxide is by definition 1. Be aware that GWPs are highly controversial.
