What is the EMRT?
Understanding the Extended Minerals Reporting Template
The Extended Minerals Reporting Template (EMRT) is a standardized supply chain reporting template developed by the Responsible Minerals Initiative (RMI). It enables companies to collect and share due diligence information about cobalt, mica, lithium, nickel, natural graphite, and copper in their supply chains, focusing on materials associated with human rights and environmental risks.
The EMRT was created to expand responsible sourcing efforts beyond traditional conflict minerals (3TG: tin, tungsten, tantalum, and gold) and address growing ESG expectations and new regulations such as the EU Battery Regulation. It helps companies demonstrate supply chain transparency and OECD-aligned due diligence across multiple high-risk materials.
The EMRT captures essential data:
- Smelters and refiners processing the minerals
- Mine locations and operators (where known)
- Country or region of origin
- Whether sourcing involves Conflict-Affected or High-Risk Areas (CAHRAs)
- Supplier due diligence policies and practices
Instead of responding to multiple custom surveys, suppliers complete one standardized template and provide it to their customers, improving consistency and efficiency across the supply chain.

What Minerals Are Included in EMRT?
The EMRT currently covers six “extended minerals”, each with distinct ethical, environmental, or strategic concerns:
Why Were These Added?
Cobalt and mica were initially added due to documented human rights risks similar to traditional conflict minerals.
Lithium, nickel, natural graphite, and copper were added more recently (October 2025), largely driven by the introduction of the EU Battery Regulation (Regulation (EU) 2023/1542), which introduces mandatory due diligence requirements for battery supply chains.
EMRT vs. CMRT – What’s the Difference?
The EMRT does not replace the CMRT. It complements it.
The Conflict Minerals Reporting Template (CMRT) focuses on 3TG (tin, tungsten, tantalum, and gold) minerals under:
- Dodd-Frank Act (Section 1502, United States)
- EU Conflict Minerals Regulation
The Extended Minerals Reporting Template (EMRT), by contrast, addresses additional minerals that are not traditionally covered by conflict minerals law but are increasingly regulated or required under ESG and battery legislation.
Today, many manufacturers must manage both templates simultaneously, creating new complexity in supplier communication and data consolidation.
- Covers 3TG (tin, tungsten, tantalum, gold)
- Focused on conflict financing
- Driven by Dodd-Frank & EU 2017/821
- Long-standing regulatory requirement
- Covers cobalt, mica, lithium, nickel, natural graphite, copper
- Focused on human rights + environmental risks
- Driven by ESG expectations & EU Battery Regulation
- Emerging due diligence and battery compliance driver
How does EU Battery Regulation relate to EMRT?
The EU Battery Regulation requires operators with a turnover exceeding EUR 150 million to conduct OECD-aligned due diligence on batteries placed on the EU market by August 18, 2027.
The Extended Minerals Reporting Template (EMRT) provides a structured framework for collecting much of the necessary upstream information. Specifically, EMRT standardizes the supplier data needed to:
- Map supply chains
- Verify smelters and mines
- Assess environmental and human rights risks
- Document mitigation measures
By harmonizing supplier disclosures in a consistent format, EMRT supports the documentation and traceability efforts required under the regulation and helps make compliance manageable at scale.
How Companies Manage EMRT at Scale
Managing EMRT effectively requires more than sending spreadsheets to suppliers.
Companies typically implement structured workflows to:
- Identify in-scope suppliers
- Distribute EMRT templates simultaneously
- Track response rates with automated reminders
- Consolidate supplier responses
- Validate smelters against RMI databases
- Generate audit-ready documentation
Modern compliance platforms like eliminate manual consolidation and enable centralized oversight of both CMRT and EMRT reporting within one system.
