mirrored listing x402 eip155:8453

Multiplies the copper quantity by literature emission factors for the chosen secondary rou

Multiplies the copper quantity by literature emission factors for the chosen secondary route and for primary cathode production, and reports the difference as low, typical and high. The factors are published life cycle averages and are stated in the response; they are not a certified product carbon footprint and are not a valid basis for a carbon credit, a customer declaration or an audited claim.
