Background: The addition of chemicals to Annexes A, B or C of the Stockholm Convention triggers the need for most parties to review and update the national implementation plans (NIPs) in accordance with decision SC-1/12. Parties have expressed the need for assistance in the process, in particular in addressing newly listed POPs that are widely used for industrial purposes and are contained in products and articles. A set of guidance documents has been developed to assist parties in establishing inventories, controlling the import of new POPs, monitoring the presence of products and articles containing new POPs, and selecting best available techniques and best environmental practices for the management of new POPs.Working languages: English and French
