The Stockholm Convention’s 2023 effectiveness evaluation reveals persistent implementation gaps in global controls on persistent organic pollutants (POPs), despite continued declines in legacy chemical levels. Conducted by the United Nations Environment Programme (UNEP), the review highlights urgent action needed by manufacturers and stakeholders in chemicals, electronics, agriculture, and waste sectors to meet key elimination targets—particularly for PCBs by 2028.
Ongoing PCB Risks Demand Industry Response
The Convention, ratified by over 180 countries, aims to eliminate or restrict POPs known for their environmental persistence and human health risks. While levels of legacy POPs like DDT, aldrin, and dieldrin are declining globally, the report raises red flags about delays in the destruction of polychlorinated biphenyls (PCBs). Only a fraction of PCB-containing equipment has been safely disposed of. Parties face a 2028 deadline to end their use entirely.
“The global goal of eliminating PCBs in equipment by 2028 is at serious risk without urgent intervention,” the report warns.
Industries that operate or service electrical equipment, particularly transformers and capacitors, are directly impacted. Delays in decontamination or disposal increase both regulatory and reputational risks.
Reporting and Compliance Gaps Undermine Effectiveness
Despite international consensus, only 70% of parties submitted national reports, and less than 50% updated their National Implementation Plans (NIPs) following new substance listings. This administrative lag undermines monitoring and enforcement, making it harder for regulators and businesses to assess compliance or exposure risks.
From a value chain perspective, companies may face increased due diligence requirements and supply chain disruptions if governments respond with tighter controls or inspections.
What Manufacturers Should Do Next
Businesses in affected sectors—especially those handling equipment, chemicals, textiles, or waste—must assess their compliance with PCB phase-out rules and monitor potential restrictions on other POPs, including PFOS and PFOA. Enhanced recordkeeping, stakeholder engagement, and waste management practices will support both compliance and corporate sustainability goals.
The Convention urges improved technical assistance and financial mechanisms to support developing countries, highlighting opportunities for service providers offering expertise in chemical compliance and waste treatment technologies.
