Question: What is the primary environmental concern associated with HFC refrigerants, such as R-410A?
Answer options: ✅ High Global Warming Potential (GWP).
- Ozone Depletion Potential (ODP).
- Toxicity to marine life.
- Contribution to acid rain.
Correct answer: High Global Warming Potential (GWP).
Explanation: HFCs, while having zero Ozone Depletion Potential (ODP), are potent greenhouse gases with high Global Warming Potentials (GWPs). This contributes significantly to climate change, leading to regulatory phase-down schedules under the Ozone-depleting Substances and Halocarbon Alternatives Regulations (CEPA) due to their role as short-lived climate pollutants.
