The Copper Mark is the leading assurance framework to promote responsible practices across the copper, molybdenum, nickel and zinc value chains. We work with companies and organisations throughout these metals’ value chains to enable them to better understand and meet the increasing demands for independently verified responsible practices, and to contribute positively to sustainable development.

We work with partners across the entire value chain to help increase the amount of responsibly produced, sourced, and recycled metal available to society, focusing on copper, as well as molybdenum, nickel and zinc.

Consolidated Mining Standard Initiative Consultation Report

We are pleased to announce the publication of the CMSI Consultation Report, outlining the feedback we received during the first public consultation on the draft Standard and oversight system. For full transparency, the CMSI partners have also made all verbatim submissions (with respondents’ consent) publicly available on the CMSI website.

We are grateful to have received so much detailed feedback from a wide variety of perspectives. It will guide updates to the Standard and oversight system that will be shared for a second round of public consultation in 2025. A response explaining how the feedback has been addressed will also be published.

Revised Monitoring and Evaluation System

The Copper Mark Monitoring and Evaluation System complements the Theory of Change by defining the data and indicators to track performance toward achieving our short- and long-term goals, as well as our intended impact.

In 2024, the Copper Mark revised the Theory of Change and Monitoring and Evaluation System.Thank you to those who were able to review and provide feedback!

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

Revised version and results of public consultations
