To determine if a refrigerant is non-ozone-depleting, checking its classification and Global Warming Potential (GWP) value is the most reliable method. The classification of a refrigerant can be found in regulatory documents and safety data sheets, which indicate whether it is an ozone-depleting substance (ODS) or not.

Ozone-depleting substances typically contain chlorine or bromine, while many modern refrigerants are categorized as hydrofluorocarbons (HFCs) or other alternatives that have been formulated to minimize their environmental impact. The GWP value provides insight into the refrigerant's potential contribution to global warming compared to carbon dioxide. Refrigerants with low or zero ozone-depleting potential and low GWP values are considered more environmentally friendly.

On the other hand, evaluating manufacturers’ recommendations, assessing color codes on containers, and inspecting the physical state may not provide conclusive information about a refrigerant’s ozone-depleting properties or its associated environmental impact. Manufacturers' recommendations may vary and could be focused on safety rather than environmental classification. Color coding can also differ between regions and does not universally indicate whether a refrigerant is ozone-depleting. Lastly, the physical state (gas or liquid) does not
