European Commission summary: 2025 COPs added chlorpyrifos, MCCPs and LC‑PFCAs to the Stockholm Convention

The European Commission’s ‘International agreements (Chemicals)’ page states that at the 2025 Basel/Rotterdam/Stockholm COPs, Parties added three hazardous chemicals to the Stockholm Convention (chlorpyrifos; medium-chain chlorinated paraffins (MCCPs); and long-chain perfluorocarboxylic acids (LC‑PFCAs), their salts and related compounds). For compliance teams, this signals that these chemicals are now listed POPs under the Stockholm Convention, which typically drives Parties’ national implementation measures (production/use prohibitions or restrictions, trade controls, and waste management obligations) and may cascade into regional implementing legislation (e.g., EU POPs Regulation updates).
