The final public consultation of Consolidated Mining Standard Initiative ran from 8 October to 17 November 2025 and provided an opportunity for stakeholders to provide their feedback on the draft consolidated standard, assurance process and claims policy. Over the coming months, the CMSI Partners will be considering every submission as they develop and finalise the consolidated standard, assurance process and claims policy.

All information and documentation relating to the CMSI final public consultation can be found here.

The Copper Mark is undertaking a revision of the Chain of Custody (CoC) Standard. The draft revised CoC Standard was open for public consultation from 17 September to 17 November 2025.

The Standard is being revised with the following key objectives:

• To facilitate a dialogue and updates to the standard based on initial learnings from the limited uptake, including addressing barriers to uptake.
• To include in the CoC Standard the remaining principal covered metals of molybdenum, nickel, and zinc.

The Terms of Reference for the revision are available here.

A summary of stakeholder engagement and feedback from the consultation is available here.

WHAT: The Copper Mark and the Rocky Mountain Institute held a consultation on the report “A 1.5°C-aligned Trajectory and Target-setting Methodology for the Copper Sector” and supporting tools. Specific deliverables that we consulted on are the following:

• Methodology: “ A 1.5°C-Aligned Trajectory and Target-Setting Methodology for the Copper” Report, please read before the next supporting documents
• Target-Setting Tool which defines all data and assumptions used in the SDA.

• • Copper GHG Target Setting Tool_v1.2
  • Copper GHG Target Setting Tool_v1.2 – archetype1
  • Copper GHG Target Setting Tool_v1.2 – archetype2
  • Copper GHG Target Setting Tool_v1.2 – archetype3

WHO: We invited all interested stakeholders to review the draft report and provide your input.

WHEN: The public consultation was open from 17 June 2025 to 17 August 2025.

HOW: We collected feedback using response form with consultation questions but also welcomed any other feedback including in other formats.

WHY: Currently, the copper industry lacks specific guidance on how to set science-based emissions targets that reflect both the sector’s need to expand production in support of the energy transition and the sector’s unique decarbonization challenges.

The report aims to fill this gap by providing copper producing companies with 1.5°C-aligned emissions trajectories a clear methodology to set emissions reduction goals that are in line with the 1.5°C target.

The report and supporting tools are intended to serve as an optional guidance for participants implementing the requirements of criterion 27 (“Greenhouse Gas Emissions Reductions”) of the Copper Mark Criteria for Responsible Production v3.0.

The current draft Sector Decarbonization Approach report has been developed by Rocky Mountain Institute in cooperation with the Copper Mark and leveraging the expert input of the technical working group.

RESULTS: Overview of responses and outcomes

In 2024, the Copper Mark updated its Theory of Change and Monitoring and Evaluation System. The public consultation closed on 31 January 2025.

The purpose of the limited revision was to:

• Ensure alignment with the revised Copper Mark vision
• Incorporate “critical issues of copper” as identified by the Impact Working Group in 2023
• Incorporate other metals (molybdenum, nickel, zinc) included in the Copper Mark Assurance Process

Relevant documents:

• Track-changed version of the draft Theory of Change used in the public consultation
• Clean version of the draft Theory of Change used in the public consultation
• Track-changed version of the draft Monitoring and Evaluation System used in the public consultation

The Consolidated Mining Standard Initiative (CMSI) is a collaboration between the Copper Mark, ICMM, Mining Association of Canada (MAC) and World Gold Council (WGC) to consolidate their four responsible mining standards into one global Standard. The vision is for a sustainable society, enabled by the responsible production, sourcing, and recycling of metals and minerals.

The CMSI's first public consultation was open from 16 October to 16 December 2024. The consultation provided an opportunity for stakeholders to provide their opinions on the draft consolidated standard, governance model, assurance process and claims policy.

All information and documentation relating to the CMSI first public consultation can be found here.

The Responsible Minerals Initiative (RMI) and the Copper Mark revised the Risk Readiness Assessment (RRA) Criteria and corresponding Criteria Guide in 2021-2023 and published the final version on 19 October 2023.

The RRA is used by over 320 mining, smelting, refining, and manufacturing sites across multiple metals including aluminum, alumina, bauxite, cobalt, copper, gold, graphite, iron ore, lead, lithium, mica, molybdenum, nickel, palladium, platinum, rare earth elements, silver, steel, tantalum, tin, tungsten, and zinc.

The RRA is both a set of criteria for responsible production and a tool for companies to communicate their environmental, social and governance practices. Its main uses are:

1. As a voluntary self-assessment and self-reporting tool for minerals and metals producers and processors participating in the RMI’s Responsible Minerals Assurance Process.
2. As the foundation of the RMI’s Environmental, Social, and Governance Standard for Mineral Supply Chains; and
3. As the foundation of the Copper Mark Criteria for Responsible Production against which sites are independently assessed during the Copper Mark Assurance Process.

Risk Readiness Assessment Revision Process

The first public consultation on the revised RRA Criteria and Criteria Guide took place from 2 May 2022 through 1 July 2022.

Summary feedback from that public consultation can be found here.

The draft documents on which stakeholders provided feedback during the first public consultation are here:

2022 DRAFT Risk Readiness Assessment (RRA) Criteria (ESP, CHI)

2022 DRAFT Criteria Guide (ESP, CHI)

All of the feedback received was discussed by the Copper Mark and RMI teams. Substantive feedback was further discussed with the joint Copper Mark/RMI Technical Committee, a multistakeholder group of technical experts. The feedback received during the first public consultation and the subsequent input from the Technical Committee led to the development of a second draft of the RRA Criteria and Criteria Guide.

The second public consultation on the second draft of the RRA Criteria and Criteria Guide took place from 1 March through 1 April 2023.

Summary feedback from that public consultation can be found here.

The draft documents on which stakeholders provided feedback during the second public consultation are here:

2023 DRAFT Risk Readiness Assessment (RRA) Criteria (ESP)

2023 DRAFT Criteria Guide (ESP, CHI)

Finalisation of the Draft

Once again, all of the feedback received was discussed by the Copper Mark and RMI teams. Substantive feedback was further discussed with the Technical Committee

The final RRA Criteria Guide was adopted by the Copper Mark Board of Directors and the RMI Steering Committee.

Publication of the final draft of the RRA Criteria and Criteria Guide (CHI, ESP, FRA, IND) took place at the Responsible Business Alliance Annual Conference on 19 October 2023.

Summary of the feedback that we received across both consultations, our responses to that feedback and lessons learned from the revision process can be found here.

The Copper Mark published its draft Chain of Custody Standard for consultation from 22 December 2021 through 28 February 2022.  The Standard is complementary to but not a replacement for an assessment of the Copper Mark Criteria, available to mines, smelters, refiners, and semis-fabricators (currently in pilot).

The Chain of Custody Standard’s core objectives are to:

• Increase transparency in copper supply chains.
• Allow customers to be confident that their copper was produced responsibly.
• To track a copper product throughout the supply chain.
• Contribute to the uptake of responsible production practices and in particular use of the Copper Mark Responsible Production Criteria (Copper Mark Criteria) and Assessment Process.
• Contribute to the increased use of recycled material and support efforts to move to a circular economy.
• Allow product-level claims of Copper Mark copper.

Thank you to everyone who provided feedback.  Your comments have been logged and will be reviewed to inform the revision of the Chain of Custody Standard.  If necessary, the Copper Mark will hold a second public consultation for any unresolved issues.

Development of the Standard

The development process is managed by Copper Mark staff through the Technical Working Group. The timeline for development, consultations, and finalization are intended to be complete for launch in 2023.

Summary documents of the public consultation are available below:

• Chain of Custody Standard Public Consultation Feedback Log
• Chain of Custody Standard Public Consultation Summary Report

The Joint Standard was developed by a working group including the partner organizations, other interested commodity associations, multi-metal company representatives, as well as OECD and LME. The Joint Due Diligence Standard will undergo an independent third-party OECD Alignment Assessment. Through the working group, the partner organizations implement a clearly defined roadmap to ensure copper, lead, nickel and zinc brands will be able to rely on the shared framework to respond to the LME before June 2022. The process includes four main phases:

• Phase 1 – 2019 / early 2020: Development of the roadmap and formation of the working group (completed)
• Phase 2 – 2020: Development of the joint Due Diligence Standard and Tool, including a public consultation (finalization of the tool in progress)
• Phase 3 – Early 2021: Pilot implementation of the joint Due Diligence Standard
• Phase 4 – 2021 / early 2022: Independent third-party OECD Alignment Assessment and application for approval by LME as Track A “OECD-aligned external standard”.

From 27 August 2020 to 30 September 2020, the partner organizations published a draft of the joint Standard for consultation. The anonymized comment log, as well as a summary report of the main feedback received and how the working group has sought to address these are published here:
