EPA 608 Core · Clean Air Act & Montreal Protocol · Medium
What is the primary difference between the Montreal Protocol and the Kigali Amendment?
Answer: A. Kigali targets high-GWP HFCs, while Montreal originally targeted ozone-depleting substances.
- AKigali targets high-GWP HFCs, while Montreal originally targeted ozone-depleting substances.✓ Correct
- BKigali regulates the use of natural refrigerants, while Montreal phases out HFOs.
- CKigali mandates the use of A2L refrigerants in all residential systems.
- DKigali is a U.S. domestic law, whereas Montreal is an international treaty.
Why A is right
The original Montreal Protocol focused on phasing out ozone-depleting substances (ODS) like CFCs and HCFCs. The Kigali Amendment specifically targets the phasedown of HFCs due to their high Global Warming Potential (GWP).
