Quizplus · Accepted Answer

The Montreal Protocol, signed in 1987, is a treaty aimed at phasing out the production and consumption of substances that deplete the ozone layer, including CFCs.

The other treaties mentioned (Geneva Protocol, Kyoto Protocol, and OPRC-HNS Protocol) do not directly address the issue of ozone depletion.
