To facilitate implementation of our policy commitments and objectives, we use a combination of audit and assessment programs along with an annual program for corporate and site-level third-party assurance of our sustainability framework – including ICMM’s enhanced Mining Principles and the Copper Mark assurance framework. Validation of ICMM’s Mining Principles and 39 performance expectations at the corporate and asset levels is a requirement of ICMM member companies and includes a mix of self-assessments, third-party assessments and transparent disclosures of outcomes. To receive the Copper Mark – a continuous improvement responsible production framework – supply chain participants across mining, smelting and refining operations in the copper, molybdenum, nickel and zinc value chains voluntarily undertake third-party assessments against their performance on various ESG risk areas. FCX has maintained the Copper Mark and Molybdenum Mark at its copper and molybdenum producing sites globally.

Across our sites in 2023, we completed 11 internal Environmental Management Systems (EMS) audits and 9 internal environmental compliance audits. An Independent Accounting Firm provided reasonable assurance over FCX’s Scope 1 & 2 GHG emissions and limited level assurance over Scope 3 GHG emissions. Our health and safety management systems and environmental management systems obtain independent certification to the International Organization for Standardization (ISO) 45001 and ISO 14001:2015, respectively. These systems include corrective and preventive action tracking for internal and external audit findings.

Our tailings management programs include inspections and reviews of all active and inactive tailings storage facilities (TSFs). Engineers of Record inspect our operating TSFs on a quarterly basis. Human Rights Impact Assessments (HRIAs) are our primary method of conducting human rights due diligence at our active operations, including a sampling of our on-site contractors and local suppliers. HRIAs are conducted by third-party consultants, who gather direct input from internal and external rights holders. In addition to our own audit programs, customers and financial institutions periodically request to conduct sustainability-focused audits or assessments at certain facilities. Our operations are routinely inspected by regulatory agencies of host governments. We believe findings and feedback from these processes provide improvement opportunities.
