Question:

Natural refrigerants such as carbon dioxide and hydro carbons (propane) have high Global Warming Potential (GWP) compared to HFCs.

A False
Explaination

Carbon dioxide and Hydro Carbon refrigerants have very low Global Warming Potential & Ozone Depletion Potential. They are not currently used because hydrocarbon refrigerants (propane) are highly flammable and CO2 refrigerant is inefficient & requires a lot of energy.
