December 2, 2019

From November 25 (Mon.) to 29 (Fri.), 2019, the Third Meeting of the Conference of the Parties to the Minamata Convention (hereinafter referred to as the “Convention”) on Mercury (COP3) was held in Geneva, Switzerland. The meeting brought together over 1,000 stakeholders.

At COP3, working-level officials held discussions on technical rules for the implementation of the Convention and on organizational arrangements of the secretariat and made progress in development of the detailed rules of procedure for the Convention.

1. Organizational arrangements of the secretariat

2. Technical matters

(1) Harmonized System codes developed by the World Customs Organization (WCO)

In response to the report on assigning product codes to mercury-added products in order to help customs identify and distinguish non-mercury-added products and mercury-added products, the parties agreed to request the secretariat of the Convention to draft a guidance document and to provide an assessment on the usefulness of such codes.

(2) Review of Annexes A and B

The Convention stipulates that the parties should review Annex A (mercury-added products) and Annex B (manufacturing processes in which mercury or mercury compounds are used) no later than five years after the date of entry into force of the Convention. Accordingly, concerning mercury-added products and manufacturing processes in which mercury or mercury compounds are used, the parties agreed that they will collect information on: technical and economic feasibility and environmental and health risks and benefits of non-mercury alternatives and other facts and that the secretariat of the Convention should compile the information into a report toward COP4 based on the opinions of an ad hoc group of experts to be established. Concerning dental amalgams containing mercury, the parties agreed to request the secretariat of the Convention to prepare an information document on the presence of mercury-free alternatives, impacts on users’ health and other facts.

(3) Releases of mercury

The Convention stipulates that the parties should as soon as practicable, establish an inventory of releases from relevant sources and adopt guidance on best available techniques (BAT) and on best environmental practices (BEP). Concerning this, a group of technical experts, which was established under these provisions of the Convention, submitted a report on its past efforts to COP3. The parties decided to request the group of technical experts to continue to develop the inventory and draft guidance during the intersessional period, and they held discussions on the coverage subject to the inventory and the guidance at COP3.

(4) Guidance on the management of contaminated sites

The parties held discussions on the draft guidance, which is an outcome of the efforts by the secretariat of the Convention in consultation with the group of technical experts, and they revised part of it and adopted the revised one. The guidance is a compilation concerning methods and approaches for: Site identification and characterization, Risk assessments, Options for managing the risks, etc.

(5) Mercury waste, in particular the consideration of relevant thresholds

The parties held discussions on the report compiled by the group of technical experts and other documents. They decided that no threshold needs to be established for “waste metal mercury, etc.” and “waste mercury-added products,” which are two of the three categories of waste mercury under the Convention, and that waste corresponding to the respective types of wastes in the list will be regarded as such mercury waste. Furthermore, the parties requested the group of technical experts to further substantiate its present recommendation that a totals concentration threshold may be appropriate for “objects contaminated with mercury,”  In addition, the parties decided to extend the mandate of the group of technical experts until COP4 and to hold discussions on related issues, including the thresholds, during the intersessional period.

(6) Effectiveness evaluation

Based on the report compiled by the ad hoc technical expert group, the parties held discussions on frameworks, organizations, indicators and other elements for evaluating the effectiveness of the Convention. The parties decided on: exchanging information on items necessary for evaluation indicators in preparation for COP4 for the purpose of further information collection and discussions; and requesting the secretariat of the Convention to prepare guidance for monitoring activities, an integrated report of national reports, and a Trade, Supply and Demand Report.

3. Future schedule

COP4 will be held in Bali, Indonesia, from October to November 2021.
