Stewardship Gaps in Asia’s Mineral Boom
New assessment flags modern slavery, climate and community risks in nickel, cobalt, copper.
A new investor-backed assessment of 14 Asian miners finds elevated modern slavery exposure across all sites, uneven human rights due diligence, and mounting climate and water stress—risks that grow as demand for critical minerals accelerates toward mid‑century.
In June 2026, the Asia Investor Group on Climate Change and the ISS STOXX Research Institute released a cross‑market assessment of sustainability performance in the region’s critical minerals value chain, a sector now central to energy transition supply lines and investor balance sheets; the study, titled “Stewardship in the Critical Minerals Value Chain,” examined 14 Asian mining operators tied to nickel, cobalt, and copper, and it did so with a lens calibrated to recognized benchmarks, aligning the evaluation against Initiative for Responsible Mining Assurance (IRMA) standards to clarify both policy posture and on‑the‑ground conduct (Das, n.d.). With United Nations Environment Programme projections pointing to a potential sixfold rise in critical minerals demand by 2050 and a market that could reach roughly $400 billion, the report’s timing underscored how performance gaps can scale as quickly as production targets, particularly where labor oversight is already thin and ecological baselines are fragile (Das, n.d.). The researchers organized findings by discrete risk areas, comparing paper commitments to implementation metrics, and then mapped climate‑physical hazards that could constrain operations or intensify community impacts across coming decades, setting a sober frame for investors considering engagement, divestment, or conditional financing (Das, n.d.).
The human rights ledger opened unevenly: nine of the fourteen operators maintained formal human rights policies, yet only seven demonstrated strong diligence systems capable of identifying, preventing, and addressing harms, and five were classed as laggards on due diligence overall, a designation that signals procedures lacking in scope, depth, or follow‑through (Das, n.d.). On modern slavery risk management specifically—an axis that covers forced labor, servitude, and related coercion—nine operators qualified as leaders or outperformers, while three were marked as laggards, indicating that good practice is present but far from universal across the cohort (Das, n.d.). The assessment further flagged supply chain exposure: seven operators were categorized as high risk for modern slavery concerns embedded upstream or among contractors, and—of structural significance—all fourteen companies operated in locations that the researchers classified as having elevated modern slavery risks, a baseline that transforms any lapse in oversight from a probability into a near‑term operational vulnerability (Das, n.d.). The throughline was clear for boards and asset managers: policy statements, while necessary, did not guarantee systems robust enough to meet the ethical and legal standards now expected in high‑risk geographies (Das, n.d.).
The gap between commitments and practice sharpened around forced and child labour safeguards, where thirteen companies counted as leaders on policy content, yet only six achieved leadership in implementation, a divergence that moved seven firms into the laggard category on measures intended to prevent the very abuses their codes prohibit (Das, n.d.). Community dynamics presented a partially stronger picture—ten operators ranked as leaders for outreach and consultation—though the lifecycle test exposed a weak flank: only two companies were leaders in planning for mine closure and rehabilitation, and twelve fell into advancer or laggard bands, a signal that long‑term environmental liabilities and post‑operation social impacts remain under‑provisioned (Das, n.d.). The assessment’s framing connected these deficiencies to plausible conflict drivers, from inadequate restitution planning to insufficient engagement with affected groups, circumstances that, in practice, can escalate grievances or trigger project delays that are costly for everyone involved (Das, n.d.). For stakeholders seeking to differentiate credible stewards from high‑risk issuers, the message was to interrogate not merely whether policies exist but whether the operational evidence—training, contractor controls, audits, remediation—matches the promise line by line (Das, n.d.).
Climate governance registered similar asymmetry: ten companies led on reducing greenhouse gas emission intensity, yet seven lagged on setting concrete reduction targets and action plans, and another seven lagged in disclosing climate risks and mitigation strategies, leaving investors without the scenario data needed to price transition and physical hazards (Das, n.d.). Those physical hazards were not abstract; under a high‑emissions pathway of roughly 4.3°C warming by 2100, the report assessed 297 Asian mining assets and projected high water stress at seventy‑seven sites during 2026–2040, rising to one hundred forty during 2026–2055, while the number of assets in the low‑stress category fell from sixty‑six to seventeen across those periods (Das, n.d.). Heat amplified the squeeze: assets facing high heatwave risk more than doubled, from sixty‑six in 2026–2040 to one hundred fifty‑two in 2026–2055, a trajectory that threatens workforce safety, processing efficiency, and local water balances already strained by competing uses (Das, n.d.). In this context, absence of targets and disclosure is not a paperwork issue but a governance deficiency with direct cost, safety, and social license implications (Das, n.d.).
The analysis tied business continuity to nature dependencies that, while often invisible on income statements, are measurable and material: mining companies derived an estimated sixty‑three percent of ecosystem service‑linked revenue dependency from regulation and maintenance services—water flow, climate regulation, and related functions—while about thirty‑five percent came from provisioning services such as freshwater resources, a profile that placed water in multiple, overlapping risk channels (Das, n.d.). Surface water flow maintenance, groundwater, and surface water emerged as the most financially material dependencies, meaning disruptions there could directly affect output, costs, or compliance, with cascading effects in host communities (Das, n.d.). Biodiversity impacts were apportioned with similar clarity: land‑use change accounted for fifty‑seven point one percent of impacts from the assessed companies, pollution drove thirty‑two point four percent, and climate change contributed ten point five percent, a breakdown that points investors toward the specific operational levers—land clearing, waste management, emissions controls—where reductions would buy the greatest ecological return (Das, n.d.). That level of specificity invited stewardship targets that are granular, time‑bound, and verifiable in the field (Das, n.d.).
Market concentration in nickel gave the findings immediate geopolitical texture: Indonesia held more than twenty‑two percent of global reserves and produced about sixty percent of global nickel in 2024, having banned raw ore exports since 2020 to promote domestic processing, while setting a sectoral goal of an eighty‑one percent emissions reduction by 2045, a target that will now be judged against facility‑level energy and water realities (Das, n.d.). On the demand side, China accounted for more than sixty‑three percent of global nickel demand in 2024, Chinese firms controlled around seventy‑five percent of Indonesia’s nickel refining capacity, and China absorbed more than eighty‑five percent of Indonesia’s ferronickel exports, a chain that gives Chinese buyers and operators significant leverage over processing standards, traceability, and remediation norms in the archipelago (Das, n.d.). For those pressing for stronger labor and environmental safeguards, that configuration suggests that engagement strategies must be transnational and attuned to where procurement decisions and processing technologies actually sit (Das, n.d.).
Investor behavior has already been shaped by these fault lines; a review of sixty‑nine mining‑related engagement cases from 2020 through 2025 showed that about half involved environmental violations and more than one‑third involved human rights violations, with pollution and Indigenous rights the most frequently raised issues, indicating where accountability is being demanded and where companies are most exposed (Das, n.d.). The report’s authors translated these patterns into a set of practical directives: strengthen investor due diligence that reaches into contractors and high‑risk tiers, prioritize engagement on implementation gaps rather than policy drafting alone, and consider capital allocation that rewards demonstrated leaders over firms stuck in chronic laggard status (Das, n.d.). Integration of climate and nature risk analytics into investment decision‑making was framed not as an add‑on but as necessary infrastructure in markets where water stress and heat will intensify and where communities bear the immediate externalities of weak controls (Das, n.d.). This is a roadmap for narrowing the distance between stated commitments and lived conditions around mine sites (Das, n.d.).
Taken together, the assessment’s detail—the IRMA‑aligned scoring, the modern slavery exposure in every operating location, the climate hazard curves that steepen through mid‑century—constructed a clear threshold test for stewardship in Asia’s mineral economy: policies must be enacted through practice that is evidenced, monitored, and built to withstand heat and water shocks as well as social scrutiny (Das, n.d.). For operators, that implies binding targets, audited supply‑chain controls, closure and rehabilitation plans that are financed early, and community consultation that is frequent and transparent; for investors, it implies active engagement, conditional capital, and escalation paths when remediation stalls (Das, n.d.). The volume of nickel, cobalt, and copper the transition will demand is no longer in question; whether it is mined with respect for workers, communities, and ecosystems is, and that decision will be captured in line items like due diligence scores, heat stress projections, and grievance outcomes, not in slogans (Das, n.d.). In the meantime, assets move into higher risk bands, and the cost of delay compounds (Das, n.d.).
