United States withdrawal from the Paris Agreement takes effect
The withdrawal notified by the United States in January 2025 takes effect approximately one year later under the agreement's Article 28 procedure, making it the second such withdrawal by the same state within a decade. The record is included for what it shows about the instrument rather than about any administration: an agreement designed for universality by making obligations nationally determined and unenforceable is also an agreement a party can leave without penalty and rejoin without cost. The exact effective date within January 2026 is stated here as a month because it was not confirmed in this session.
Historical — it happened, and the record is settled.

Paris Agreement
Supports the temperature goal formulation, the nationally determined contribution architecture with its ratchet and transparency provisions, the absence of any enforcement mechanism, and the entry-into-force and withdrawal procedures. V55 verification basis: the treaty text was not retrieved in this session; the decision reference is given without the full UN document symbol because that symbol could not be confirmed, and no article is quoted verbatim.
