Which international environmental treaty, designed to combat global ozone depletion, was ratified by the Kingdom of Saudi Arabia in 1993?
Answer and explanation
Correct answer: A. The Montreal Protocol
- Step 1: Review international treaty ratifications: The Montreal Protocol on Substances that Deplete the Ozone Layer phases out chlorofluorocarbons (CFCs) and halons.
- Step 2: Saudi Arabia acceded to the Montreal Protocol in March 1993, implementing strict national phase-out schedules for ozone-depleting substances.
Answer
The Montreal Protocol.
Why not the others: 'Kyoto Protocol' is an earlier carbon emissions framework; 'Paris Agreement' is the 2015 global climate accord; 'Ramsar Convention' protects international wetlands.
