BHP and Amazon have established a pilot for environmental attribute certificates linked to copper concentrate and cathodes from Chile’s Escondida mine. BHP says the certificates would recognise lower greenhouse gas emissions within copper supply chains and could be retired against copper used in Amazon’s infrastructure.
The pilot is intended to examine eligibility rules, governance and safeguards against counting emissions reductions twice. It addresses a traceability challenge: copper passes through several processing and manufacturing stages before reaching users.
The announcement describes a framework under development, rather than an established certification market.
This brief is based on BHP’s announcement of September 22, 2026. Company statements and forecasts are attributed to their source. This is a summary of the announcement, prepared by Mining Brief, rather than independent on-site reporting.
