BHP and Amazon Pilot Separates Low-Carbon Copper Attributes from Physical Trade: What It Means for Recycled Copper

BHP and Amazon launched a pilot in September that creates environmental attribute certificates (EACs) for low-emissions copper from the Escondida mine. Under a Book and Claim model, Amazon can buy and retire these certificates to count supply-chain emissions reductions, without physically taking the copper. This separates the metal's environmental value from its physical flow, which could change how buyers evaluate copper's carbon footprint. The pilot raises a key question for recycled copper. Recycled copper uses about 85% less energy than primary production, but its environmental value depends on traceability and verified data. If primary copper can sell low-carbon attributes separately, recycled copper may need to demonstrate its green credentials through documented origin, recycled content, and processing emissions. This could eventually lead to a dual pricing structure where environmental attributes add a premium to material with solid verification. For now, scrap prices still hinge on copper content and market fundamentals. But the trend toward verified low-carbon claims suggests that 'inherently low-carbon' is giving way to 'demonstrably low-carbon'. Companies that can prove their environmental data will likely find better access to decarbonizing supply chains.

Book and Claim for copper is interesting. It decouples the green attribute from the metal itself, which could work if the registry and verification are solid. But I'd want to see how baselines are set and whether double counting is controlled. Without that, it's just greenwashing.

Agree on verification. The pilot only covers Escondida, so scale is tiny. Also, does the EAC account for actual emissions reductions from the mine's process, or just average vs baseline? That's the crux. Recycled copper's advantage is real, but if primary can buy attributes cheaply, the incentive to use scrap might weaken.

The market design question matters. If these EACs trade freely, they need clear additionality and ownership rules. For recycled copper, the real shift is that it can no longer rely on being 'low carbon by default'. It has to prove it. That's a higher bar but also a chance to differentiate with solid data.

I think the article nails it: recycled copper's advantage is energy savings, but that only counts if you can verify it. With primary copper getting EACs, buyers now have options. Scrap processors that invest in tracking and carbon reporting could capture a green premium. Those that don't might lose access to green supply chains.

From an industrial efficiency angle, the 85% energy saving for recycled copper is huge. But the processing route for mixed scrap can eat into that. If EACs for primary copper get cheap enough, some buyers might not bother with scrap at all. The key is whether recycled copper can prove its own low-carbon story with numbers.
