BHP and Amazon have launched a pilot that turns the lower emissions of copper from Chile's Escondida mine into certificates Amazon can buy. It is an early attempt to put a verifiable label on greener copper.
At a glance
- BHP will create certificates recognising lower emissions from copper concentrate and cathodes made at Escondida, the world's largest copper mine.
- Amazon can retire the certificates against copper used in its power, cooling and computing hardware, including AI chips and circuit boards.
- The pilot will test rules for eligibility, governance and safeguards so no certificate is counted twice.
Background
A tonne of copper passes through smelting, refining, fabrication and manufacturing before it reaches a product, so it rarely carries proof of how it was made. Environmental Attribute Certificates (EACs) solve that by separating the claim from the metal. A producer issues a certificate for lower-emissions output, and a buyer retires it against the copper in its own supply chain.
What happened
BHP and Amazon have set up what they call an industry-first pilot to buy and sell certificates for lower-emissions copper. The certificates are tied to copper concentrate and cathodes from Escondida in Chile, the world's largest copper mine. Escondida draws its electricity from renewable sources and runs on desalinated water.
BHP will create the certificates, and Amazon will retire them against the copper in its power, cooling and computing infrastructure. That includes the circuit boards, chips, interconnects and cold plates that run its AI systems.
How the certificates work
BHP describes the scheme as "in-setting" rather than offsetting. The credits apply only to emissions inside copper supply chains, not to projects elsewhere. That matters because buyers can then point to cleaner copper, not to unrelated carbon savings.
The hard part is trust, and the pilot is built around it. The partners will test eligibility criteria, a governance framework and safeguards against double counting, so each certificate can be verified, traced and registered. Michiel Hovers, BHP's group sales and marketing officer, said the pilot "could help develop a practical pathway" to buyers that want "credible and verifiable lower emissions materials".
What it means
Big buyers increasingly want to know, and to shape, the emissions behind the copper they use. A working certificate market would let a low-emissions mine earn something for its cleaner output without tracking each tonne through every smelter and factory.
It also lands in a live debate. There is still no agreed definition of 'green copper', and India's Copper Vision Document mentions the idea without setting a benchmark. A working scheme between the owner of the world's largest copper mine and Amazon's cloud business could help shape what that standard ends up looking like.
Our read
Outlook: neutral. The pilot changes how copper's emissions are recognised, not how much copper is mined or used. Any premium for lower-emissions copper would sit on top of the benchmark price rather than move it.
What to watch
- The eligibility rules and double-counting safeguards the pilot settles on, which could become a template for other producers.
- Whether other copper miners or technology companies join a lower-emissions certificate market.
- Moves by governments, including India, to write a formal definition of green copper.

Detailed analysis
Demand Drivers
Buyers such as Amazon want verifiable data on the emissions behind the copper in their power, cooling and computing hardware.
Mining Production
Escondida, the world's largest copper mine, runs on renewable electricity and desalinated water, which lowers the emissions tied to its output.
What could lift prices
- Technology buyers are showing they will pay attention to how copper is produced, not just its price.
- A certificate market could reward low-emissions mines and support investment in cleaner supply.
What could weigh on prices
- The pilot adds no new copper supply or demand, so it offers no direct support to the benchmark price.
- Certificates only work if buyers trust them, and the double-counting safeguards are still being tested.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Chile | Medium | Copper from Escondida, the world's largest copper mine, is the basis for the pilot's certificates. |
| United States | Low | Amazon will retire the certificates against copper in its cloud and AI infrastructure. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Copper Mining | Positive | Lower-emissions mines could earn recognition for cleaner output through certificates. |
| Data Centers | Neutral | Operators gain a possible way to account for emissions in the copper they use. |
Who gains, who loses
- BHP: It gets a way to be rewarded for Escondida's renewable power and desalinated water.
- Higher-emission copper producers: If certificates catch on, their copper could look less attractive to buyers tracking emissions.
Other ways this could play out
- If the safeguards prove workable, other miners and buyers could adopt the same certificate framework.
- If buyers doubt the certificates, the pilot could stay a one-off between two companies.
Price risks
- A formal market for lower-emissions copper could open a price gap between cleaner and dirtier metal.
- Disputes over double counting could undermine trust in any premium the certificates carry.
