Stockholm Convention on Persistent Organic Pollutants

The Stockholm Convention on Persistent Organic Pollutants is a multilateral environmental treaty that commits its parties to control and phase out chemicals that persist in the environment and accumulate in living organisms. Its text was adopted by a Conference of Plenipotentiaries held in Stockholm on 22 May 2001 and it entered into force on 17 May 2004. The United Nations Secretary-General acts as depositary of the authentic texts. The Convention is administered together with the Basel and Rotterdam Conventions through a joint secretariat. The Conference of the Parties has repeatedly amended Annexes A, B and C to list additional chemicals, adopted Annex G on arbitration and conciliation procedures in 2005, and published a revised consolidated text in 2025 that includes the decisions of its twelfth meeting.
