The Stockholm Convention Clearing-House Mechanism (CHM) meeting page indicates POPRC-22 will be held 21–25 September 2026 in Rome, Italy. The agenda includes consideration of a revised draft risk profile for polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs) and mixed polybrominated/chlorinated dibenzo-p-dioxins and dibenzofurans, following a prior deferral and requests for additional Annex E information on linkages between long-range environmental transport and adverse human health effects. For compliance teams, this is an official process milestone that can signal future scope clarifications and potential future listing actions, informing substance monitoring and stakeholder engagement planning (e.g., preparing technical data submissions if relevant).
The Stockholm Convention Secretariat published the official meeting information for the 22nd meeting of the Persistent Organic Pollutants Review Committee (POPRC-22), including the meeting dates (21–25 September 2026) and venue (FAO Headquarters, Rome, Italy). The meeting overview also highlights technical work relevant to future POP listings, including consideration of a revised draft risk profile for polybrominated dibenzo-p-dioxins and dibenzofurans and mixed polybrominated/chlorinated dibenzo-p-dioxins and dibenzofurans, and the related invitation for Parties/observers to provide Annex E information. Compliance teams tracking upcoming global POP listing actions should monitor POPRC-22 agenda items and associated information calls, as POPRC outputs can progress substances toward future COP listing decisions.
The Stockholm Convention Secretariat’s POPRC-22 overview page announces that the 22nd meeting of the Persistent Organic Pollutants Review Committee (POPRC) will take place in Rome, Italy, 21–25 September 2026. The page indicates POPRC will consider a revised draft risk profile for polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs) and mixed polybrominated/chlorinated dibenzo-p-dioxins and dibenzofurans (mixed PBDD/PCDD/Fs), and references requests for additional Annex E information (e.g., long-range environmental transport and adverse effects). For compliance teams, this is an official process milestone that can signal forthcoming recommendations for new POP listings or scope clarifications, which may later translate into national/regional implementing controls.
The European Commission’s international agreements page states that Parties, at the 2025 Basel/Rotterdam/Stockholm COPs, added three hazardous chemicals to the Stockholm Convention (chlorpyrifos; medium-chain chlorinated paraffins (MCCPs); long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds). For compliance teams, this is a confirmation of new global POP listings that can trigger downstream national/regional implementing measures and updates to restricted substance lists, supply-chain declarations, and product stewardship programs in Parties to the Convention.
The Stockholm Convention CHM COP Decisions page is identified in the research as the official landing page to retrieve COP-12 outputs, including the report and the decisions adopted at the twelfth meeting (advance versions). For compliance teams, this page is an authoritative entry point for tracking adopted COP decisions that may include new listings, exemptions, technical guidance mandates, or compliance mechanisms requiring future implementation by Parties.
The European Commission’s international agreements page indicates the Commission decided to close its proposal to nominate octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6) for listing under the Stockholm Convention. For compliance and horizon-scanning teams, this signals that this specific EU-driven nomination pathway has been halted, potentially changing expectations/timelines for any future Stockholm Convention consideration of these substances via that route.
The Stockholm Convention Compliance Committee initiated an information-collection exercise under its 2026–2027 work programme (referencing decision SC-12/22) by publishing questionnaires for Parties and for supporting entities, with responses due by 2 March 2026. Compliance teams at Parties (and relevant supporting organizations) should plan resources to complete and submit the requested information by the stated deadline, as inputs may inform compliance-related consideration under the Convention’s mechanisms.
The Stockholm Convention Register of Specific Exemptions page for PFOA, its salts and PFOA-related compounds includes an exemption entry (noted in the research as for the European Union) describing a specific allowed use and setting review/assessment milestones including a review by 31 December 2026 (and periodic reviews thereafter). For compliance teams, this provides authoritative confirmation of the existence and review timing of a time-bound treaty exemption that may be relied upon by eligible Parties for the specified use while planning phase-out and future review submissions.
A UN Depositary Notification (C.N.672.2025.TREATIES-XXVII.15) communicates the COP-12-adopted amendments to Annex A of the Stockholm Convention to list chlorpyrifos, MCCPs, and LC‑PFCAs (their salts and related compounds). For compliance teams, this notification is a key procedural milestone for the amendments’ treaty lifecycle (including objection/non-acceptance procedures and entry-into-force mechanics) and should be monitored because national/regional implementing measures may reference the notification date and resulting timelines.
An official Stockholm Convention BAT/BEP meeting page indicates an implementation work programme to update Best Available Techniques/Best Environmental Practices guidance to reflect recent Stockholm Convention outcomes: incorporating MCCPs into SCCPs-related guidance, including LC‑PFCAs in PFOS/PFOA-relevant guidance, updating UV‑328 BAT/BEP guidance reflecting COP-12 exemption amendments, and considering in June 2026 whether to develop BAT/BEP guidance for chlorpyrifos. For compliance teams, these updates can affect operational expectations for controlling releases and managing wastes/industrial processes linked to newly listed POPs and exemptions.
At the 12th meeting of the Conference of the Parties (COP-12), Parties adopted decisions to amend Annex A (elimination) of the Stockholm Convention to list chlorpyrifos (decision SC-12/9), medium-chain chlorinated paraffins (MCCPs) (SC-12/10), and long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds (SC-12/12). For compliance teams, this is the international legal basis that triggers downstream implementation actions by Parties (national/regional bans or severe restrictions, plus any exemptions) and should be tracked for supply chain impacts on substances, mixtures, and articles.
The POPRC-20 follow-up page compiles official Secretariat invitations for comments and information that support the POPRC technical evaluation process for potential Stockholm Convention listings and related documentation. Items highlighted in the research include (i) an invitation dated 22 January 2025 for comments on indicative lists and explanatory notes relating to long-chain PFCAs, PFOA, and PFHxS (deadline shown on the page as 9 June 2025) and (ii) an invitation dated 10 March 2025 for comments on the draft risk profile for PBDD/Fs and mixed PBCDD/Fs (deadline shown as 14 April 2025). For compliance teams, these consultations signal potential future listing actions and evolving scope/interpretation for PFAS and brominated dioxin/furan substances under the Convention process.
