The latest amendment to the Montreal Protocol is?

The Kigali Amendment is the most recent change to the Montreal Protocol, aimed at phasing down the powerful warming gases used to replace CFCs.

There is no recognised Nairobi Amendment to this protocol, so that name does not fit.

The Copenhagen Amendment was an earlier step that tightened control on ozone depleting substances, not the latest one.

There is likewise no Bangkok Amendment in the sequence of protocol changes.

Adopted in 2016 in Rwanda, the Kigali Amendment targets the phase down of hydrofluorocarbons.

By curbing these strong greenhouse gases it links ozone protection directly with climate action.
