As the global energy transition gathers pace and geopolitical uncertainty reshapes international trade, mining and metals companies are facing growing pressure to demonstrate not only how metals are produced but also how they move through increasingly transparent, resilient and responsibly managed value chains, highlights assurance framework body The Copper Mark value chain director Mike Smith.

He says this shift represents a fundamental change in how the mining industry approaches responsible production.

While environmental, social and governance (ESG) considerations once focused largely on mine sites, attention is increasingly turning to the entire journey of metals, from extraction and processing to manufacturing and, ultimately, the finished products.

Responsible sourcing, traceability and supply chain transparency are becoming commercial imperatives for producers of copper and other critical minerals, as downstream manufacturers require more certainty regarding the origin of raw materials and whether they have been produced responsibly.

Smith tells Engineering News & Mining Weekly that the latest responsible sourcing developments reflect a broader ongoing transformation across global metals markets.

“The world is going to need more metals and materials. The International Energy Agency (IEA) predicts there’s going to be a doubling in demand for metals and minerals to meet the energy transition over time. Coupled with that, you’re also seeing increasing demands for those materials to be produced in a way that minimises environmental and social impacts.”

He emphasises that rising demand and rising expectations will continue to reshape upstream-downstream partnerships, environmental and assurance alliances, and government and community ties across the mining value chain.

Beyond Responsible Mining

Established as a responsible production assurance framework for the copper industry on March 31, 2020, The Copper Mark currently covers about 40% of global mined copper. Against this backdrop, Smith argues that responsible production can no longer be viewed solely through the lens of mining operations.

Instead, the organisation is broadening its focus beyond upstream mining, smelting and refining to encompass processors, manufacturers and downstream consumers.

Smith says this strategy reflects a growing recognition that sustainability commitments made by various value chain stakeholders – including automotive manufacturers, electronics producers and renewable- energy companies – will ultimately depend on greater visibility into their raw material supply chains.

To support that objective, The Copper Mark is introducing a Midstream Standard for processors and fabricators, alongside a Chain of Custody Standard designed to trace responsibly produced metals throughout the value chain.

The organisation is also establishing the Responsible Metals Value Chain Platform, which will bring together mining companies, manufacturers and end-users to improve collaboration and information sharing.

Rather than solely verifying mine sites, the aim is to provide confidence in the responsible journey of the material throughout the value chain, he says.

Transparency Focus

Smith highlights that the increased emphasis on transparency is being reinforced by a series of global disruptions that have exposed vulnerabilities in international supply chains.

The Covid-19 pandemic, for example, highlighted the risks associated with highly concentrated supply networks, while geopolitical tensions and shipping disruptions have encouraged companies to reassess their procurement strategies.

Many companies “may only really have visibility of one or two tiers into the manufacturing process; they don’t know where the smelter or refiner is and they don’t know which mines the material has come from”, he adds.

The need to close such information gaps is becoming increasingly important, as businesses aim to strengthen supply chain resilience and reduce operational risks.

Smith also notes that companies are consequently moving away from traditional “just-in-time” procurement towards more resilient sourcing strategies that prioritise transparency and supplier diversity. This creates an opportunity for mining companies to differentiate themselves from their competitors by providing independently verified information about responsible production.

Smith says mandatory due diligence legislation, particularly in Europe, requires companies to demonstrate a greater understanding of the ESG risks embedded within their supply chains.

He also notes that although many of these regulations originate in consumer markets, their effects extend throughout global mineral supply chains, adding that mining companies supplying international markets increasingly need to provide assurance that materials have been responsibly produced, regardless of where they operate.

Complexity Reduction

Moreover, Smith believes that recognised sourcing standards can play an important role in helping companies to meet those expectations.

“It’s becoming really important as a way to ensure market access because where there are due diligence requirements, companies have to understand their supply chains and have assurance around how those metals and materials are produced.”

These requirements are not applicable to European producers only, as companies operating in Africa, Asia and Latin America increasingly face the same expectations if they want to supply manufacturers serving regulated markets.

For African copper producers, in particular, demonstrating responsible production is likely to become an increasingly important source of competitive advantage as demand for energy transition minerals continues to grow.

Yet translating responsible production into a meaningful competitive advantage is not without challenges. As Smith notes, one of the greatest challenges is the proliferation of responsible sourcing frameworks, with mining companies often having to comply with multiple customer requirements, exchange rules and industry standards, which create duplication and increasing compliance costs.

The Copper Mark is aiming to address that complexity by improving interoperability among different assurance systems.

For example, The Copper Mark assurance already meets the LME’s responsible sourcing requirements.

The organisation hopes to build additional equivalencies that enable companies to demonstrate compliance across multiple frameworks through one recognised assurance process.

That objective extends to the Consolidated Mining Standard Initiative, under which The Copper Mark and three other major mining standards (the ICMM, the Mining Association of Canada, and the World Gold Council) have spent the past three years developing a unified global responsible mining standard. The proposed framework is intended to apply across commodities, jurisdictions and operations of all sizes, simplifying assurance while maintaining robust governance.

Once finalised, The Copper Mark will take ownership of the new standard and manage its implementation.

The new mining standard is a core component of the organisation’s evolution later this year which will see it adopt a new name, brand, and independent governance structure to fit its growing mission.

Transparency is also becoming increasingly important in relation to environmental reporting and with customers requiring lower- carbon materials and greater recycled content, mining companies are under growing pressure to provide comparable and independently verified data.

However, various organisations often use different methodologies to calculate greenhouse-gas emissions and recycled content, limiting meaningful comparison, Smith says.

Rather than introducing another reporting framework, the organisation aims to support greater alignment around existing methodologies while promoting consistent verification and disclosure.

Comparable information will become increasingly important as manufacturers want to reduce the embedded carbon intensity of products ranging from electric vehicles to renewable energy infrastructure, he elaborates.

Environmental Sustainability

The growing focus of the mining and metals industries on responsible value chains signals a broader shift in the role of sustainability.

Responsible production is no longer regarded as an ESG consideration or corporate responsibility initiative only. Instead, Smith highlights that it is becoming closely linked to market access, customer relationships, investment decisions and long-term competitiveness.

For producers of critical minerals, demonstrating responsible production through transparent, independently verified value chains is likely to become an increasingly important differentiator.

He notes that as governments pursue energy security, manufacturers diversify supply chains and regulators tighten due diligence requirements, companies capable of providing trusted information about the origin and movement of their materials are likely to be better positioned to compete in evolving global markets.

From a Copper Mark perspective, the future of responsible mining will not be defined only at the mine gate but also across value chains that connect producers, processors, manufacturers and consumers through greater transparency, traceability and trust.
