6.3.7 (HL)—UN role

The IPCC assesses evidence; the UNFCCC and COP process negotiate commitments; the Montreal Protocol and Kigali Amendment regulate specific substances.

Keep roles distinct: science synthesizes findings, parties negotiate rules, and governments implement them. Kigali links ozone governance to climate by targeting high-GWP HFCs.

An IPCC assessment can inform a COP decision, but it does not itself legislate a national emissions limit.

IPCC; it assesses science and does not enforce policy.

A negotiated commitment and a scientific assessment have different authority and functions.
