Development of the Joint Due Diligence Standard for Copper, Lead, Nickel and Zinc

Facilitated by The Copper Mark, a working group has been established to develop the joint Standard to enable brands’ compliance with the LME Responsible Sourcing requirements. The group also includes other interested commodity associations and multi-metal company representatives, along with the OECD and LME. Through the working group, the partner organizations will 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 (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”.
