Refrigerants - Ozone Depletion and Global Warming Potential

Common refrigerants and 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 greenhouse gas to Carbon Dioxide where GWP by definition is 1.
