Explain Why Montreal Could Coordinate a Phase-Out
The Montreal Protocol is an international treaty controlling the production, trade and use of CFCs and other ozone-depleting substances; it is widely regarded as the most successful international environmental cooperation to date.
A scheduled phase-out, monitoring, differentiated responsibilities, finance and technology support, trade controls and national law aligned action around a specific measurable chemical pathway.
A phased CFC reduction gives manufacturers time to replace equipment while monitoring tests whether atmospheric ODS levels fall.
Its success depends on commitments, timelines, reporting, assistance, domestic implementation and revision as substitutes create new risks.
International agreement is not magic compliance; domestic law, finance and monitoring complete the chain.
