UNSCR 2254 was adopted unanimously by the UN Security Council on 18 December 2015. It is widely treated as the principal international reference point for resolving the Syrian civil war by political rather than military means.
The resolution endorsed earlier diplomatic frameworks — notably the 2012 Geneva Communiqué of the Action Group for Syria and the Vienna statements of the International Syria Support Group (ISSG) — and folded them into a single Council-backed process. Its core elements include:
- Syrian-led, Syrian-owned political process facilitated by the UN, with formal negotiations between the Syrian government and opposition representatives.
- A timeline calling for credible, inclusive and non-sectarian governance within six months, followed by drafting of a new constitution.
- Free and fair elections under UN supervision within 18 months, open to members of the Syrian diaspora, to "the highest international standards of transparency and accountability."
- A nationwide ceasefire to take effect in parallel with the political process, explicitly excluding ISIL (Da'esh), Jabhat al-Nusra and other groups designated as terrorist by the Council.
- Humanitarian access, release of arbitrarily detained persons, and support for confidence-building measures.
The resolution requested the Secretary-General to convene representatives of the government and opposition, work that was carried forward by successive UN Special Envoys — Staffan de Mistura, Geir Pedersen — through the Geneva talks and the Constitutional Committee launched in 2019.
Implementation has been minimal. The parallel Astana process led by Russia, Iran and Türkiye, the entrenchment of the Assad government with Russian and Iranian military support, and disagreements over sequencing (constitution versus elections, ceasefire scope, detainee files) stalled progress. Nonetheless, Western states, the Arab League and the UN routinely cite 2254 as the only legitimate basis for a settlement, and it is regularly invoked in Council debates and sanctions justifications.
Example
In 2023, as Arab League states began normalising relations with Damascus, Western governments insisted that any reintegration of Syria be tied to "meaningful progress" on UNSCR 2254, including the Constitutional Committee and detainee releases.
