The Montreal protocol worked because it was focused on a limit set of changes. Something similar could also work again if metal satellites and uncontrolled hypersonic reentry spaceship metal parts were outlawed as well.
Unfortunately, the lack of a gradual set of limited changes is why the same process cannot be replicated for climate change remediation. Countries are trying to tackle the entire problem as an "impossible" monolith rather than breaking it up into separate industry and lifestyle practices to address incrementally.
