Council of Europe AI Framework Convention: The First Binding International AI Treaty
The Council of Europe Framework Convention on Artificial Intelligence and Human Rights, Democracy and the Rule of Law (CETS No. 225) is the first legally binding international treaty on AI. Opened for signature in Vilnius on 5 September 2024, it entered into force after five ratifications — and as of August 2026, signatories include the EU, UK, US, Japan, Israel, and 30+ Council of Europe member states. Unlike the EU AI Act (which regulates market access), the Framework Convention creates obligations across the full AI lifecycle: transparency, accountability, privacy, non-discrimination, and human oversight — with specific provisions for public-sector procurement (Article 14) and remedy mechanisms (Article 15). For procurement officers: any AI system purchased by a signatory government after the Convention enters into force domestically must demonstrate compliance with these lifecycle obligations.
The Council of AI provides a verified measurement credential that maps Convention articles to measurable system properties — Article 10 (transparency), Article 12 (accountability), Article 13 (human oversight), and Article 14 (procurement safeguards). This is not a legal opinion. It is an auditable measurement: for each article, a measurement card shows the system's actual properties, signed and verifiable against the published Council public key.
If a vendor claims Convention compliance without measurement evidence, ask for the Council card.
