EPA 608 Core · Ozone Depletion · Easy
What is the Ozone Depletion Potential (ODP) of HFC refrigerants such as R-134a and R-410A?
Answer: C. 0
- A1.0
- B0.5
- C0✓ Correct
- D100
Why C is right
HFCs (Hydrofluorocarbons) do not contain chlorine or bromine, meaning they have an Ozone Depletion Potential (ODP) of exactly zero. However, they are regulated because of their high Global Warming Potential (GWP).
