ESG Components: Disaggregating the Three-Pillar Framework

ESG & CSR Mining → Conceptual Foundation

ESG disaggregates corporate performance into three measurement domains. Each pillar contains specific indicators that rating agencies, investors, and regulators evaluate. Understanding component structure determines which data systems to build and which performance gaps carry material risk.

ICMM Mining Principles cover 38 performance areas organized across environmental stewardship, social responsibility, and governance accountability. This structure reflects the ESG framework applied globally.

Environmental Pillar

Mining's environmental footprint is measurable and highly material to valuation. Key indicators include:

• Climate Impact - Scope 1, 2, and 3 greenhouse gas emissions measured in CO2 equivalent. Mining operations are energy intensive; carbon pricing and transition risk directly affect operating costs.

• Water Management - Volume extracted, consumption rate, discharge quality, water stress context of operating locations. Water scarcity makes this increasingly material in arid regions.

• Biodiversity - Impact on critical habitats, endangered species, offset programs. ICMM principles specifically address biodiversity conservation as a core performance expectation.

• Waste Management - Tailings facility integrity, hazardous waste handling, circular economy initiatives. The Global Industry Standard on Tailings Management (GISTM) emerged from catastrophic failures like Brumadinho (2019, 272 deaths), establishing strict requirements for tailings facility design and oversight.

• Mine Closure - Financial provisions for remediation, progressive rehabilitation plans, post-closure water treatment. Regulations now mandate upfront jaminan (guarantees) for closure costs to prevent abandoned sites.

Social Pillar

Social performance determines whether communities accept or resist operations. Metrics include:

• Workforce - Local employment percentage, diversity ratios, training investment per employee, health and safety (LTIFR - Lost Time Injury Frequency Rate, TRIFR - Total Recordable Injury Frequency Rate, fatality rates).

• Community Relations - Investment in community development as percentage of revenue, grievance mechanism effectiveness (response time, resolution rate), consultation process documentation. ICMM principles emphasize building positive relationships with Indigenous Peoples through respect, meaningful engagement, and mutual benefit.

• Human Rights - Due diligence processes, security force conduct, resettlement protocols aligned with IFC Performance Standard 5, supply chain labor standards. The OECD Due Diligence Guidance provides detailed recommendations on identifying, addressing, and mitigating risks of human rights abuses and conflict financing in mineral supply chains.

• Economic Contribution - Taxes and royalties paid, local procurement spending, infrastructure investments. ICMM principles require ensuring that investments in mineral resources enhance social and economic development locally and nationally.

Governance Pillar

Governance quality affects all other ESG performance. Weak governance enables environmental violations and social conflicts. Indicators include:

• Board Structure - Independence ratio, diversity, ESG expertise of directors, committee structure (audit, sustainability, risk).

• Executive Compensation - Linkage between ESG metrics and variable pay, disclosure transparency, alignment with long-term value creation.

• Ethics and Compliance - Anti-corruption policies, whistleblower protections, conflicts of interest management, sanctions and violations record.

• Transparency - Financial disclosure quality, beneficial ownership clarity, payments to governments reporting (EITI compliance), ESG data verification and assurance.

• Risk Management - ESG risk integration into enterprise risk framework, scenario analysis for climate and social risks, board-level oversight mechanisms.

Materiality and Weighting

Not all indicators carry equal weight. Materiality varies by commodity, geography, and operating context.

A copper mine in water-scarce Chile faces different material ESG risks than a coal operation in Indonesia. Rating agencies like MSCI and Sustainalytics apply sector-specific weighting, tailings management scores heavily for hard rock mining, methane emissions for coal, artisanal mining due diligence for gold and cobalt.

Major miners like BHP, Rio Tinto, and South32 implement ICMM principles which provide measurable performance indicators for each sub-principle, enabling consistent evaluation across diverse operations.

Component understanding drives data architecture. Companies must instrument operations to capture these specific metrics, verify accuracy through third-party assurance, and disclose results in standardized formats. Gaps in measurement infrastructure translate directly to poor ESG ratings and higher capital costs.
